The thing I really love about 8-bit computers is the fact that you can literally understand the entire thing including the CPU and ram and even the whole electrical design of the motherboard. I never lived through the 8-bit computer era, but I really do love how simple and clean they are to understand, except for the programming for me at least.
It really was another time. In those days spirits were brave, the stakes were high, men were real men, women were real women and small furry creatures from Alpha Centauri were real small furry creatures from Alpha Centauri. And if you wanted to play a game on a CD you had to start by writing your own kernel.
Yeah, I was thinking the same thing. Also, "David asked me to design a board that could interface the C64 with the Gamduino. Here it is." I guess this is a product of a time when really using a computer meant understanding the computer (when it was possible to understand a computer completely).
I don't think you're quite aware how rudimentary a kernel for an 8-bit CPU needs to be in order to fit the project goals. For example the Apple][ ROM was only 4k That's 4096 bytes. Basically it has to handle serial and character IO by polling IO addresses, it needs to output to display memory, it needs cold and warm reboot entry routines that set up memory and the display. That's about it.
@@linuxgeex I don't think you're quite aware how crap I am at assembly. But seriously, I know it is nothing on writing a kernel for a modern machine. But it is non-trivial. I had a hard time in college trying to write an assembly function that took a number and changed the base. Even if it isn't a ton of code, it does require pretty intimate knowledge of the hardware and is difficult to debug. Not exactly a Saturday afternoon project. Particularly for most developers today who are used to high-level languages with visual debuggers and profiling tools such as myself.
I used a visual debugger for 6502 in 1984... it was called the Apple ][ monitor lol. But I think you're right in that the idea of what is 'difficult' these days has changed. Current generation is too accustomed to everything being handed to them on a silver platter, and a prize for last place. It's a great world they want to live in but it's hard to build anything that lasts out of snowflakes.
Since LGR collects old computers and since old computers typically came in beige (especially business level machines like the IBM PC’s and compatibles and most Macs prior to the iMac G3 (1998). You can thank the Germans for this. Apparently, back in 70’s and 80’s when the personal computers first came to be and became popular, Germany (more specifically what was then West Germany) had enacted an office regulation law dating back to the late 70’s regarding workplace standards that required office equipment including computers to be light-value colors such as off-white, pearl, beige, light grey, etc. This office equipment color standard spread to other parts of Europe. Because computer manufacturers of business computers such as DOS/Windows PC’s didn’t want to have to build separate computer and monitor case colors for North America and Europe, they settled on boring beige or light grey colors as standard. The first DOS/Windows business computer to not come in beige/grey was the black colored original IBM Thinkpad laptop models (300, 700, & 700C). IBM wanted it to stand out so they insisted that Germany grant them an exemption which Germany eventually did but also requiring IBM to include a warning with the Thinkpad that it was not for Office use. They original iMac G3’s and 2nd gen. Powermac G3’ desktop Macs would also break free of the beige/grey color standard, though I don’t know if they too were given any sort of similar exemption or if the standard still applied by 1998. Now some of you will recall there are 70’s/80’s home computers in non-beige/grey colors, particularly black (such as the Sinclair ZX Spectrum and Amstrad computers) and that was because they were not business computers so they where exempt from the German workplace office equipment color standards.
Being born in 1985, these BASIC computers are a little before my time, but in high school I had a TI-83 Plus calculator that came with a nice thick manual. I spent a ton of time going through TI-BASIC and coding games and messaging apps. It was amazing and really got me into programming.
Maybe that is what is wrong with modern computers (even the Raspberry Pi) and why there is a wanting to go retro, the all but zero documentation that comes with them. The last computer I had with decent docs was an NEC APC3, I was able to have some great time programming it.
I think the TI-83/84 plus calculators are pretty great for people interested in a modern 8-bit computer aesthetic. They have similarly limited hardware, a simple OS which starts immediately and shows little more than a blinking cursor, and they have a lot of documentation included with examples for how to program them in BASIC. You can also program them in assembly and directly write to any of the of the hardware registers. There are also "plugins" which extend the Basic version so you can call those commands from a BASIC program. They also have a community around them which has been able to do very impressive things with the limited hardware.
Hell.. even simply just GAMES nowadays. I know it's a little hypocritical to say that I like to just get into a game from the start with tutorials and such, but I fondly think back at the (sometimes) extensive manuals games could come with that lets you ponder over every little thing the game featured, even though most of it you could figure out by playing :D Back in primary school a buddy's father owned a Apple Macintosh and he had SimAnt for it, which had a game manual that not only contained all the ins and outs of the game, but a full biology section (hundreds of pages) about ants and ant life, which subsequently made me learn more about ants and I photocopied the entire manual. Now it's just a simple "Quick Install Guide" or "Quick User Guide" and the rest is all just about playing. Even though nowadays you just want to just install a game and get playing, there's something about having extensive documentation going with it that you can study outside of the game :D
Well, the Ti-83 uses a Z-80, so a tad more modern (by one year) but used almost as widespread as the 6502, and fully intel 8080 compatible. It even runs Doom!
@@WickedMuis The extras were often included to hide the fact that the games themselves were pretty limited compared to their modern day counterparts. It's also tied to the distribution system - today games are "shipped" digitally, which is a Good Thing™ as physical media, packaging and shipping just add cost. If you want extensive manuals and extras today you can still get them: simply buy the "Collector's Edition" and pay extra for the privilege.
My thing about 8 bit machines - they were completely knowable. Both from a software and hardware perspective. I knew my TRS-80 Model I so well - that when the characters started dropping bits I knew which RAM chip went bad. And that Tandy/RS socketed the RAM. Plus I knew enough about the Z80 CPU that I didn't use an assembler - I'd poke stuff into memory direct from poke/peek. The other benefit was instant on as soon as power was applied.
"instant on as soon as power was applied." - I miss that too - the C64 had a cartridge slot, I had the Terminator game in there, awesome back in the day. Trying to make a phone call on my "smart" phone is a chore now as well as I have to dismiss so many ads before I can actually make a call!
Indeed. I'm getting pretty involved in my Tandy 1000HX right now making expansion cards for that goofy PLUS header. I realize that people do make adapters to go from PLUS to 8-bit ISA (XT), and I've even made one of my own, but you quickly realize that space is still an issue, so the best solution is to build your card straight onto a PLUS card.
I wrote a word processor for the commodore pet that used the tape deck for the data at wrote directly to the cassette so was not limited by the computer memory. It was shown on the BBC TV program Tomorrow's World around 1978 or 1979.
Perhaps he should just talk to a Chinese OEM manufacturer, which would whip one up to Dave's exact specs in a short time, and produce it in quantity very affordably. That's what Chinese do very well, inexpensive mass production. Course one would have to keep a close tab on production, because they are known for lack of quality. Just my two cents. ;)
Some parents seem to have this idea that kids should be limited in computer time, i've always disagreed somewhat, that its not the computer time that kids need to be limited, its the internet time. Computers without internet are very different devices. A non connected computer is more of a personal and introspective experience than a connected computer
@@sullivanzheng9586 Even games are fine, just don't give them modern kid's games or shows those look like something to make you in to a person with no brain functions. And it is a bit mean but what my dad and my brother did was to let me figure out myself what to do. Countless hours studying how to get pirates games to work and how to solve old driver issues :D Ah I miss not having money 10 years ago at age 13 trying to get stuff to run on intel hd graphics. Edit: I don't miss the 5400rpm hdd though.
The argument is that computing time lowers creativity. Perhaps it is so, but I think that they really miss working with their hands, and playing with an Arduino and blinking LEDs based on the input of a photo resistor with it will undo that lack.

OMG!! My first pc was a vic-20!!!! XD I was totally enamored with the fact I could change colors, scroll lines of text and poke addresses that made beeps and boops come out of it ^_^ Up until then any access I had to a computer was one that had some sort of basic GUI and pre-installed games... it totally blew my mind.. I never did manage to get a tape drive for it, but I had a few carts that plugged into the back if memory serves me right... Still nothing was more amazing than taking a game from pages of a magazine and (after painstakingly copying it line by line) fiddleing around with the code to make it do other things :) I remember I had some sort of ASCII adventure game, but it had no sound ... so I must have threw in like a hundred diff pokes so every time you moved it booped, and encounters had a little doo-de-doo kind of melody before they popped up ^-^ I was ssuuuuper proud of it too, I must have (over a few weeeks) re-compiled the damned game at least a few hundred times.... and even wrote all my addidtions on paper with annotations in the magazine I copied the game from XD I am gonna ask my mom if she still has my vic20 stuff (fingers crossed but I doubt it) I wouild love to see that again.. as it was like 30 years plus ago.. my memories are VERY faint.. god would I love to get my source and make a proper compiled version of it today XD THANKYOU for blowing my mind and letting me remember this cool stuff dude :) Always loved your work, this just totally blew me away with nostalgia!

Of course this was meant to be joke. I recall seeing a 500 meg. Hard drive at a software etc thinking who would ever need that much storage when wordperfect ran off of 2 floppy disks. 🤣
I remember the first time I booted up a IBM compatible 386, with it's massive 45MB HDD. Coming from a C64, young me was blown away at the thought of having most every game I owned on hard drive, with no need to swap or flip floppies. Cue 1997 when we finally left the C64 and 386 (we used both side by side as there was a lot of documents on the C64 we couldn't transfer without a lot of work) behind for a 450MB HDD AMD K6-2 Win95 machine. Then Baldur's Gate came out with it's 2GB size and 5 CD install...
Look dislikers, if you want to waste your time watching "Linus Tech Tips" "build" a "gaming" PC then go waste your time. But People who build a computer completely from scratch are legends. thank you, 8-Bit. Great content!👍👍👍
The RC2014 is a Z80 based computer designed in 2014. It's actually pretty good and can use a Pi zero to drive the screen and keyboard etc. Take a look.
I wish I lived when 8-bit computing is "mainstream" and you could manually adjust registers on the fly. These systems made you understand what was happening and it was simple enough to learn through playing with it. I wish this because I would have a greater understanding of why things evolved to what they are today and a greater appreciation for the modern hardware that seems so abstracted away from me in the modern Windows PC and even in the Linux world to a point.
The VIC-20 was my first computer. I got it for Christmas but mum & dad gave me the manual to read in advance and I read it cover to cover about a *million* times before the big day - it was a great manual! I was completely hooked from that point on. :)
You can get relatively cheap FPGAs (sub $9) that'd be able to handle VGA no problem and maybe some extra I/O stuff on top. Keep in mind that $50 may be pushing it in terms of unit cost. The WDC 65C816 (6502 CPU) is $7 alone on Mouser, an FPGA to handle VGA will be another $7 - 12 (i.e. Spartan-IIA Xilinx) and the DRAM will run you around $2-5 (Digikey: 1MB, 8Bit Parallel SRAM). Then you'll need circuitry for misc I/O, SD card interfacing (prob another low level FPGA) and interfacing to the CBM Serial bus which is another $10 due to the FPGA used. The power circuits will run another $5-8 (assuming you want to power it from microUSB) and the board required (you'll be needing atleast a four layer board) assuming 5" x 5" will run $20-25/unit (PCBWay: 4 layer, 6/6mil rules). Assembly will also be potentially costly depending upon volume. If you want to hand assemble, you'd need a reflow oven, hot air tool, solder paste, as steady hand and a stencil. Hand assembly is cheap, but if you go to volume (say 50 board run) you're looking at ~$15 - 25/unit (PCBWay: Turnkey Kitting, ~100 SMT parts, ~5 TH Parts i.e. connectors). $100 is definitely on the high end, but $65-75 / unit is probably more realistic. But this is only back of the napkin math, so there can definitely be some cost savings abound. It'd definitely be a challenge to do the interface over an 8 bit parallel bus whilst aiming for the goal of everything being near bare metal accessible to any coder (as opposed to something like the VIC chip using its VRAM straight from the main data bus to which the programmer can just directly address VRAM instead of obfuscating it through the 8 bit parallel bus).
When buying in bulk the price per unit drops, and considering he is open to using modern components these costs are a bit nuanced but you bring up an (unfortunate) reality.
He showed his GameX selling something like 50 games a day. I have idea insight into his numbers, but I'd say a run in at least 100s of units. 50 would be big for you or me, but check out his subscribers! And two sizeable channels giving adivice here. That's a huge audience. I'd guess easily 50 a month, or per week.
What I miss about 8-bit computers: I miss feeling in control of my computer. Maybe it was slow. Maybe it was limited. But it was mine and it didn't do anything(literally nothing) that I didn't tell it to do. I miss the immediacy of the computer following my instructions(How many times have you double clicked on something which didn't respond immediately despite your computer being thousands of times faster than an 8-bit computer). I miss being able to understand what my computer is doing and why(I don't even know how many millions of lines of other people's code is running on my computer nor do have enough time in my life to read all of them even if they were available). I miss being able to run programs without internet access. I miss software being designed specifically for my computer instead of being forced to buy the computer that the software vendor asks for. I miss being independent of huge corporations sending me updates that do God only knows what or why. I miss my computer not getting slower as it ages(How many times has someone told you to buy a new computer because yours is running slower than it did when you bought it). I miss being able to write and run my code without needing multiple devices(development board, cable, software tool chain, and computer used for code editing) which all have to be compatible with each other. I'm the kind of guy who leaves specific wrenches and screwdrivers in places where I'm going to need them so that I don't have to go looking for them later and it irritates me when I have to scrounge together a development environment to alter the behavior of a "brick" which I haven't touched in 3 years. I miss being forced to get creative while adapting my task to a set of known constraints as opposed to the modern paradigm where you just write a logically sound(but perhaps inefficient) program and throw resources at it until it works acceptably. What I don't miss about 8-bit computers: Low capacity floppy disks and the difficulty of moving data from one computer to another.
@Jack's Model Railroad , that's true and they are so cool for what they were built for - simplicity. Modern computers are made for enormous complexity, and they can be used in a very user-friendly way or get dived into extremely deep and complicated engineering. Let's say that back with 8-bitters we behaved in simpler ways, and expected much simpler stuff. Perhaps we don't miss 8-bit, we miss ourselves and simpler times. Because - less is more, keep it small and simple, DIY, small is beautiful... etc. Human being is cursed with finding new ways to get his life complicated, comforting oneself that it somehow makes life easier. Oh, well, tragicomedy drama.
I definitely understand your love of that first 8 bit computer. In my case, the gateway drug was a TRS-80 model 1. Within months, I knew what every single byte in the memory was for and as every device on the system was memory mapped that meant I understood EVERYTHING about that system. Even when I moved up to the disk system extension I was still comfortable with each and every part of the system (though, my investment was about $1500.00 in 1979, I was quite as comfortable with the expenditure). Sadly, with today's systems, I don't even have an inkling about what is going on in the sound card (the trs-80 had a relay to stop and start the cassette recorder, if you switch that on and off quickly enough, it made a sound .Hi-fi, it wasn't). Even at the age of 79, I do still enjoy programming the latest chipsets but the nostalgia for the 8 bit days is intoxicating.
@Michael Dina Yes, but asking for help doesn't necessary means "make it open source". I.e. I can ask for help, and in the end, implement things like I want, with closed source, based on user's ideas. Which is what it looks like, but let's hope it's just my misinterpretation.
If you're using an FPGA for video you should be able to synthesize dual-port RAM which would allow you to directly access it both on the C64 side and the video driver itself. You'd need a voltage conversion on the C64 side which just requires a few extra chips (like an Everdrive)
I did much the same on BBC computers with BBC Basic when I was like 9 or 10. I used to get excluded from school for using the computer rooms at lunch-time. Apparently it was s silly fad and so was use of calculators... LOL Who's laughing now?
I'm guessing 8 bit guy is the same age as me as he went through the same vic20 experience initially. I wrote so many games in a mixture of basic and machine code (no assembler then) to shift graphics around.. Annoyingly I chucked the tapes a few years ago, I would do like to see my creations (of a 14/15 year old me) again. I then migrated to the atari ste and released a few games on that and then the gp2x games console. I'be been lucky in that I'm an embedded software engineer since the mid 80s and would never have got into this without my parents helping me to buy that initial vic20. I owe them so much and thankfully they lived long enough (my father died a few weeks ago at the age of 90 from pneumonia, possibly triggered by this covid-19 virus, my mum died from cancer 3 years ago, aged 81) to see me have a successful and interesting career. I'm now 53 and considering retiring in 7 years but feel I will miss messing around writing software at a low level once I do that. Dunno why I had to post this but thought it was a good placeholder to say thanks mum and dad for being such great parents and I miss you.
For sound capabilities I would highly recommend Yamaha's OPL FM synthesis. It's instantly recognizable, nostalgic, and sounds pretty darn good. The benefit with OPL and FM synthesis in general is that, unlike the SID, it is purely digital and has no analogue filters, which dooms the SID to either be recreated in custom silicon, or faked in software. The OPL chips such as the OPL2/YM3812(used in AdLib and Sound Blaster), and the OPL3(used in Sound Blaster 16) and their clones can also be had for a dollar or two, and I know of several people designing and building brand new Sound Blaster compatible cards, as chip stock can still be found readily online, but there's more to it than that. With OPL, you can recreate the whole chip in an FPGA and have it be identical to the original in every way, and there's already code available online to do just that. OPL and FM synthesis in general, unlike the SID, is purely digital and has no analogue filters, which dooms the SID to either be recreated in custom silicon(absurdly expensive), or approximated in software(all SID chip replacements use this method still). The digital to analogue converter that usually paired with said OPL chip runs at a nonstandard frequency alongside the OPL, with a master clock at 14.31818Mhz and a sample rate of 49.7159KHz, which may prove a little more odd to replace with modern parts, but far from impossible. Nevertheless, it shouldn't be too difficult to implement and because of the nostalgia and past popularity, it would have a much greater following and ease of use as well. It might prove hard to take full advantage of OPL with the 65816 when multitasking, if the clock speed is as low as the original processors. Here's an example of some code I found for an OPL3 (YMF262) chip replicated in an FPGA: github.com/gtaylormb/opl3_fpga
Why not a ym2612? Personally I like the sound of that chip compared to the OPL ones, at least from what songs i've heard that were made between the two
The most challenging aspect of the Kernel will be dealing with the 64K blocks of memory. Yes the 65816 can address 24-bits, but moving across the 64K chunks can be quite tricky since the ALU is 16-bit (a simple jump table doesn't cut it). There are already solutions to this if you poke around the various forums (6502.org, etc.)
@@colejohnson66 x86 segments can start almost anywhere and overlap each other. Segments of 65816 is just all memory divided into 64K chunks. So you can run a normal 6502 or 65816-enhanced code in a segment, but if you need more memory, you need to long jump to another segment (or perform a long read to reach data there). Not too bad, actually, 65816 is very simple easy to learn device, just like 6502.
@@colejohnson66 Same concept, different implementation. Instead of an offset that gets added to the address like x86 there is an 8-bit bank register which specifies which 64K chunk you are working in.
As part of my master degree I had to design a 20 command Microprocessor/Micro controller. I had an idea from the 68HC05 Trainer board, which only had a 16 key keypad and two seven segment displays I learned Assembly on. I design a actual computer around my Micro controller, added five more commands to allow it to be programmed, and added a series of LED;s to the top that could show the status of each bit of the registers. I when way above the requirement of the assignment, and I did get an A, the instructor wrote "fine" on my report. I keep that report, and have shown it to other instructor at the schools I have been an adjunct at. At least one has said it would be a great computer for people to learn assembly on.
I painted a 4116 chip on my school bag in 1987 with silver metallic paint. Since it's much more difficult to paint a 6502 and I did not have a broken CPU chip, I painted that 2 kB memory chip and glued a real 4116 chip under the enlarged painting.
I had no interest in the games you developed as your last 2 long-term projects, but this computer is a product I could see myself actually buying (assuming you are able to keep the cost reasonable).
I think for me, the appealing aspect of 8 (and 16 bit) computers was the simplicity, yet complexity in terms of what you could do with them (of course, by today's standards these are nothing, but back then, you could do some pretty cool stuff, and you didn't have to worry about things like updates, viruses -- at least not as much -- and other things you battle with today, software compatibility, drivers, security, etc). They were a simpler computer, but a more fun experience IMO over what we have today. Granted what we have today is great, but as computers got more complex, so did the upkeep (so to speak) of them.
If you’re using the 65816, something you should know is that bank zero contains the stack and 16-bit interrupt vectors (and since they’re 16-bit, the interrupt handlers are expected to be in bank zero as well). So for bank 00, you’ll have to do some odd stuff where the bank is part RAM (for the stack) and part ROM (for the interrupt vectors and handlers). Source: W65C816 Data sheet + “Programming the 65816” by David Eyes / Ron Lichty
I thought the stack was page 2 on the 6502, and has its own high-bits register on the 65816? Oh! You mean the first 64K, not the first page. Why not copy a ROM image to RAM, scattering segments to various addresses if it is discontinuous, at reset? You could use a cheap serial flash chip and be cheaper than a full bus interface.
John Długosz That sounds like more work than should be needed. The location of the interrupt handlers can be anywhere within bank zero. The interrupt vectors that point to the handlers have set addresses. For example, the RESET vector is located at FFFC,FFFD. For the general IRQ vector, it’s located at FFFE,FFFF in Emulation Mode and FFEE,FFEF in Native Mode.
That’s not hard. I’m designing my own 65816 system and as I come from an Acorn background it’s going to be somewhat like a BBC Micro/Master memory layout. So bank 0 has a 32K static RAM and 2 x 32K EEPROM devices. The reason for 2 is 0x8000 to 0xBFFF was paged ROM (it could support 16 “sideways” ROMs) and 0xC000-0xFFFF is for the OS. The 32K OS is two 16K banks switched by the emulator pin (because the Acorn OS has vectors for OS calls which clash with the 16 bit vectors). Finally the edge connector has a ME line which if pulled low deselects ALL of the onboard memory. It’s taken about 5 TTL chips to do this.
Well, since you didn't ask me, I'll share anyway... What I missed about the Commodore 64 was the excitement of new things. Amazing things that were never done before. From games to office productivity. Everything - from the beginnings of email to BBS's to cool games. Everything and everyone was on a race to the next great idea and there was no shortage of them either. We simply don't have much of that anymore. Sure, graphics are better - sure, sound too - but in the end, most of everything we have today is just an improved version of these 80's developments.
The fact that you have seen the c64 kernel source could be a problem... You had better hardcore CYA to make sure that none of your code is at all similar to c64 code otherwise they could make your life extremely difficult with copyright issues.
I otoh haven't seen the C64 ROM code, but I've seen the Apple ][ and ][+ ROM code (because they were published openly like IBM's). Of course, that's only 2K, and it's very easy to NOT do the same thing.

Interesting project! Reminds me of a discussion I had with my cuz. He, born in 72 and I, born in 86 have entirely different computer origin stories. He started with the Vic 20 I believe and I cut my teeth on a Packard Bell 386 with Windows 3.1. This lead to entirely different computer experiences. Which ultimately lead to entirely different career paths. He went into industrial programming and I went into networking. Long story short, it still baffles me every time I see anyone program in assembly or whatever being someone who grew up windows and GUIs.
As much as I hate to suggest another forum to monitor, I suggest you make a subreddit for this project. The reason is that I don't have a Facebook account, nor will I ever. If it were just me, I wouldn't be making this suggestion. However, I'm pretty sure I'm not alone in this opinion. With that being said, I think reddit might be a better place for discussion anyway, as you have ways to segment the discussion. I am not familiar with Facebook groups or their features, but I can say with confidence that Reddit does have these features in an easy to use and easy to reference format.
Even teens no longer use facebook, it's just not cool anymore. And I don't think it was ever known to be a platform for any kind of intellectual thought discussions going on.
One thing I miss about old 8 bit machines (mine was an Atari 800xl) was the ability to access the physical bus or program the game sockets. The most interesting thing I did was replacing a paddle controller with a light sensitive cell and creating an optically triggered alarm.
What I miss about 8-bit computers is the need to be creative to make something useful out of a limited set of resources. Resources that I fully understand. Each nook and cranny. The hunt for 10 more bytes of program space. The smart tricks to cram one more function in an already-full memory.

He had a demonstration system that was based on a bunch of ideas, constraint programming, custom languages graphics and other concerns, in fact including a system for generating new languages as needed.
I spent my entire childhood as a TRS-80 Coco guy, fighting the "dark side" as represented by all my Commodore friends, and here we are, 35+ years later, and between you and Ben Eater, you guys have me happily and enthusiastically joining that dark side!! UGH.. My 12 year old self would be so ashamed.. :-) Keep it up.. I look very much forward to buying one of your computers once they're ready! Actually... I look forward to buying at least 3 more as gifts for others! I cant believe I am thinking of trying my hand at 6502 assembly...
7:15 Clint's whole section in this video is exactly what I love about retro hardware and is something I've really been struggling with as a game developer. I actually have a license to work on modern hardware as an indie but still I feel that there's no limits with the modern hardware and thus I feel I'll end up making a game that feels just like every other game or worse will just not be that interesting or fun because well "I could do anything, so I did this" Richard O'Brien, the playwright behind the Rocky Horror Show (1973) and Shock Treatment (1980), has a quote that I think really applies here and has become the basis of my mindset as a developer "Limitations inspire creativity", this comes from the person who had to rework their movie to be recorded completely indoors after a writers strike caused outdoor filming in America to no longer be an option so they rewrote the movie to take place in a TV studio where all the locations were no represented as shows on the channel. This is a lesson I think many developers could learn from nowadays, sure the AAA companies won't but that's okay, indies could as those limitations are already there in other ways so why not make a game within them instead of trying to reach outside of them. I've seen various "retro" looking games that didn't adhere to the limitations of the old hardware and that just made the game feel off to me as I knew that's not how the old graphics looked so it made the game feel surreal. For some games that was the point and those games used the dissonance to their benefit but some were supposed to be convincing and just weren't. So that's what I miss about 8-bit computers, if you tried to fly you hit the ceiling and reality would come back into perspective instead of letting you clip through the roof and off to space like modern hardware does. In non-metaphorical terms, it actually restricted you to adhere to it's limitations and if you wanted to escape from them, you had to be more clever and even then it still kept you down to Earth.
I wonder if Bill Herd, the former lead engineer and creator of the C128 might be able to help him out with stuff. Bill did guest star in the Commodore History series in the Plus4/16 (TED machines) and C128 episodes and he's intimately familiar with all the Commodore machines, likely especially the 64. EDIT: Bill also knows what the VIC II did and didn't do and might have input on a good replacement.
I would actually prefer subtractive synthesis. The SID even had analog filters. With FM you tend to get those cheesy casio-keyboard sounds. But yeah they can be charming too. I would really love to have both FM and subtractive, but if the whole thing is to cost around $50, that might be hard.
@@letMeSayThatInIrish the YM2608 has a YM2149 core in it that has 3 square wave channels like the SID chip, it also has 6 four operator FM channels that can be tuned to produce some realistic instruments, it includes another 6 built in drum channels and one sample channel. it also has GPIO.
I love legacy relics of the golden age of personal computers that required an artisan to operate i remember my at and xt computers up till 16 and 32bit computing blew the minds of us nostalgic geeks... these machines required skill or hidden talent to operate.. i learned QBASIC aka quick basic when i was 11 and got ms dos 6.22 and windows for workgroups wfw 3.11 for my birthday
I just want something game artist friendly for development and easy to port to modern platforms. Good sound card would be rad too. Also, I don't want to use facebook.
Even a not very good sound system could be good enough. If you want low cost, perhaps making the video character fetching system fetch a few extra bytes during retrace could give you the audio DAC values. 3 16 bit values would be more than more than enough to make sound clips play.
What I miss about 8-bit machines was watching in amazement that programmers could overcome the extreme limitations placed on them to create some real masterpieces. That's why I'm a big fan of the Atari 2600 & IBM PC demoscenes.
The greatest unpopular micro, the Atari 800L. Aww man I still really want one buy I could never find a good one. Tramiel had something to do with it, the same ideas appeared later in Amiga machines. What a great time!
The "floppies were so slow" was solely an issue of poor design by Commodore and Atari (weird both companies made essentially the same error). My first PC was an Apple IIe and thank God (or rather Woz) it had a very fast floppy drives and 80-column support out-of-the-box. That made programming and things like word processing (Apple Writer IIe got me through all my high school writing assignment) very nice. While the Apple IIe suffered when it came to graphics and sounds, Woz's efficient design that allowed for a fast, cheap disk drive and 80-columns made both ubiquitous. Those two base features kept the Apple II line alive long after it had any right to be relevant. Many game devs used Apple IIe's as their "workstations" (sometimes with custom IO boards in a open Apple II slot) and cross-compiled to the "more powerful" Atari and C64's.
Yeah, I never though about floppies as being slow back in the day with a ZX Spectrum clone. Compared to 5 minutes of loading from a tape, 5-15 seconds loading from a floppy was a breeze.
I did both an English minor and Comparative Lit minor at University on Wordperfect for Apple IIe. Green monochrome monitor because my parents wanted to minimize game time. Although come to think of it, it needed an "80 column/ 128 kb RAM card", -not out of the box!
Vyl Bird: You are quibbling over the sense of "design" being used ... the original design concept was better than the final delivered design, as shown by the much better C128 serial disk interface, which is much like what the C64 would have been if the CIA's had been able to do hardware serial I/O on the serial bus.
The problem with using stuff like the Gameduino is that you very quickly end up with a very powerful graphics processor being scripted by a very simple applications processor --- you get completely insulated from the platform and might as well be writing in Javascript! Also, the Gameduino is anything but cheap, costing about two to three Raspberry Pis. It's possible to bitbang VGA using an 8-bit AVR, at a fraction the price, although that's probably not suitable for game graphics, but it shows you don't need high-end electronics to generate modern video. If you aim at VIC-chip like capabilities you can probably replicate the same functionality using a slightly higher-end processor without going for a full-on high-end graphics chip.
I get that feeling with full control on old machines. It did what you told it to do and if it did something it wasn't supposed to, it was more than likely your own fault. And wringing every inch of performance out of that C64 or old PC by tweaking just felt great.
Kernel writing isn't that hard , its like falling out of a tree once you broke your arm , your back in the tree to brake the other arm ;) It's a program , think simple memory and time shearing thoughts
Is quite impressive that he’s doing that I’ll give him that but I’m 13 and I’m actually working on a small kernel of my own :/ but still he is going beyond that and putting it in his own hardware, not only that he’s doing it only in assembly, I’m doing it in assembly and C which makes it much easier. At this point idk why I’m writing this lol I’m fucking stupid
One of the negatives of 8-bit computing noted here is one I miss: the long loading times, especially from cassettes, especially the 1st time loading a game. The anticipation of how the game will be. I actually miss it so much, I turn off Turbo Load on my emulators.
I personally would have gone with a Motorola 68000 CPU. The 68000 has a flat 32bit address space, hardware multiply, it's simple, it has a very simple and clean instruction set, there's better C compilers for it. Every register is 32 bits The 6502 is kind of tedious
@@alerey4363 I suppose so. I'm not sure why you'd want to stick with 8 bit, though. You could get a C64-like experience with a significantly faster, easier to use, cpu for the same price as a 6502
Because the m68k is not even close to the fun and elegance of a 6502 or derivatives. Having coding for both of these systems in the past, one can see why m68k died the way it died (not even spark succeed, and spark was based from the m68k... but to be honest, the old good computer era died with the m68k...), and the 6502 heritage is still in use as of today (arm). Of course if you don't like the 6502, you probably like the m68k. To each it's own.
@@terramap2902 it's pretty well accepted that the 68000 has one of the most human-friendly ISAs. I moved from coding the 6502 to the 68000 in the 80s. The 68k was enormously more developer friendly. With the 68000, ALU operations have a nice bag of addressing modes to pick from. It makes a smoother flow writing code. I do want I want to do in one instruction rather than four or five. Not to mention the 6502 barely has any registers. While the 68000 was ahead of its time with a large number of general purpose 32bit registers. Naturally this makes coding the thing more pleasant as you spend less time juggling the registers and/or stack. On top of that, the 68010 supports privilege levels, so you could make a proper OS, which makes it more interesting from a comp-sci point of view, some of the 68* series also supports memory mapping
Well.. it seems that [your dream computer] != [8-bit guy and the rest of us dream computer.]. Not trying to begin a holy war between dead architectures anyways (well.. not so dead considering m68k->spark, 6502->arm, z80->x86), so i'll stop here. Let's just say, we agree to disagree :) (tho, my dream computer is a 6502 based machine, with 16 MB ram, multiple graphics modes, raster interrupts so video chip with non fixed RAM (so you can move the data anyplace inside the main RAM) is a must for me, at least 64 multicolor sprites, MIDI sound would be good, but depends on the audio chip he will put in there, and the standard ps2 port is not a bad idea... i think the RPI serial port can also be a good idea to thinker with, but i don't know if an internal sd card would be a good idea due to licensing involved...
one suggestion, move off Facebook. maybe use Discord? there are many reasons for this, but mainly Facebook is just scummy. hope this doesn't sound too negative. love you!
I can understand, that you find Facebook scummy. But Discord? They are not really better. I personally think a forum would be the best solution, because you probably have different topics to cover and you'll probably don't want to read through a whole Chat-History just to find the thing you are searching for. If you recommended Reddit, it would have been a whole other story(I personally don't like Reddit either, but it would've been a better suggestion).
@@MrDavibu thought about saying Reddit as well, though honestly a forum on his site would be the best solution. just wanted to spark the discussion really.
Facebook has a much larger user base and is also much more accessible by the majority of people. If he used his own site it would be better but still not as streamlined as Facebook.
The Acorn Atom was a beautiful computer to use, in its day. The ability to code assembly language into BAsic programs, which could have offsets and macros, so the code could be saved to tape , and then reloaded into the required locations. Or the code could be compiled in site and then called. And the indirection operators ? ! for byte and 16 bit word access to memory directly. And of course the expansion bus was compatible with the mprevious System 3 And it was the foundation for what would have been the Proton, but in fact later became the BBC MICRO , *sigh*
Hey!! I _loved_ my BBC model B. My first computer really :) Loved it. I bought one last year but it arrived with no IC's inside lol. Damn eBay so refunded it. Archimedes has some cool machines too, aww those were the days.
Immediate gratification when you turn on an older system. It just brought up what you wanted, and fast. Same for the programming, no layers to access or go through to do low level bit manipulation. Great video!
While yes, the statement on the 65816 is backwards compatible is indeed correct, some older 6502 games used illegal opcodes, something that doesn't work on the 65816 (were overwritten with the newer opcodes).
Well, since this would be a new system, it wouldn't run old stuff for C64 anyway, so that backwards compatibility wouldn't be an issue. No VIC & no SID = not a C64. He's only using it as a general guide for architecture design. Make a C64-like machine freed from some of the more annoying limitations that don't "breed creativity"
@@zerobyte802 I'm saying this less of for backwards compatibility with C64 games, but more in the sense that some illegal opcodes are really useful; some do two intensive instructions at once, and save space in the process.
You should take a look at TI graphing calculators, they're basically the closest mass produced modern equivalent to old school 8 bit computers in terms of closeness to the hardware and their limitations and I know a lot of people who first learned to program on them. It's usually relatively easy to start doing assembly on them, the memory and the speed are somewhat limited so you have to take that into account when writing programs, and they typically come with pretty extensive user manuals, plus you can hookup a TI-Keyboard to get a closer experience.
The things are still $100 USD in stores and the 83+(!), the gold standard in math graphing calculators, can't do audio without sacrificing every cycle of the CPU to output to the 2.5mm port! I loved them in school simply because the Gameboy was relevant at the time and it's not like I had anything better to do... "Oh yeah, watch this date rape video" No thanks, I'll code my own rooms for a Doom engine I translated from the TI-85.
@@DoomRater True but can you think of any other modern 8-bit system with as much of a community? Most modern single board 8-bit computers are little hobbiest things and don't have anything close to the community you see for TI calculators. They're also significantly cheaper used, as little as $20 for a TI-82. The newer color editions bridge the gap somewhat between 80s computers and calculators. Granted it lacks dedicated sound hardware but it's theoretically possible to set up a DSS situation or even wire in a SID with a microcontroller
Okay okay, second hand market rules, and I own a few calculators that way, but how many parents know to do that? The color systems are something to behold, but my research is non-existant on them. I don't really know what they're capable of right now. Just keep in mind we have to get this knowledge to parents of kids in high school who are going to need the industry standard.
@@DoomRater The 84 Plus CSE can do some clever stuff with audio but the 84 Plus CE is still pretty new and nobody has built a DAC for it, that said the 84 Plus CE has basically the most powerful 8 bit chip on the market right now (eZ80 48mhz) so it certainly wouldn't be short on cycles running a dac.
The thing I like most about 8 bit computers is the fact that I am sitting in a modern world with modern, cutting edge technology, using what was once considered those same modern things. This is why I like the CRT/composite, floppy or cassette drives, and all the things that are so hard to get, because I enjoy the thought of using something that was once cutting edge.
same - there was a tutorial in one issue of Rainbow Magazine and I started programming text adventure games in BASIC at around 10 years old on the CoCo II.
Yeah, I was dismayed when the FB group was mentioned. FB is spying on users on behalf of governments, peddling mainstream fake news and suppressing and censoring alternatives. I've deleted my account, so won't be able to join the group sadly.
You really need a 100% custom kernel, otherwise Cloanto will sue you even if you license the old Commodore ROMs. Even mentioning that you looked at the code might get you sued, even with a 100% original kernel, since Cloanto is primarily a lawsuit troll company. Likewise, the Commodore BASIC v2 or v7 will be copyrighted still, by Microsoft. It may be better to implement FreeBASIC or OpenBASIC if you're going that route. Both are derived from QBASIC, have available compilers, and actual graphics routines. Going from there; if you're using an FPGA anyway, it can drive the VGA output I believe. For IO, is there a reason to choose PS2 peripherals? Why not pick up a USB controller, since USB keyboards, joysticks, and mice are common now? I don't think I've had a PS2 connector on my last two or three desktop builds, and I certainly haven't seen a PS2 keyboard for sale in ages, only USB. How will sound be handled? Something like an OPL chip?
agreed, set aside some funds to see an attorney who has a track record specializing in these things before getting too financially invested. all it takes is a request for an injunction to shut you down at the very least, and at worst competely drain your resources to zero. not sure you would be able to afford a six figure litigation team to fight something they have a case for.
There's a difference between being compatible with Microsoft Basic and shipping with Microsoft Basic. Shipping with a FreeBasic but being compatible with Commodore Basic v2 would be by far the safer way to go.
tenshi7anegl: They can still sue. They could well be looking for just enough of a claim that it's not immediately dismissed, since for copyright trolls, sometimes it's not the threat that they will beat you in court that they are counting on, but rather the cost and inconvenience of having to go to court to beat them.
I didn’t know MVG was on a video from the 8-Bit guy, right on!! I love MVG, even if I understand half of what he talk about, still very interesting to watch
If you want to learn about "computer architecture" you might as well pick any ARM SoC and go through the datasheet for it. Proper buses like pci are rare so it's mostly like an old machine with a better CPU running it.
Those datasheets are monsters though. An old Z80 is ~200 pages. Even a simple ATmega328 μC is almost 700 pages. If you add all of the design and relevant app notes this could easily top 1k pages. That's no small task for the inexperienced to tackle. There is a ton of assumed and contextual information in modern datasheets. Between the sales terminology, inflated metrics, and intentionally omitted info it's no walk in the park to learn on modern hardware in my (recent) experience. -Jake
@@UpcycleElectronics >An old Z80 is ~200 pages. The Z80 isn't a SoC. The block diagram of a recent SoC is going to be a single page and then you can get any info you want to know about a block from the reams of data provided.
In the early 90s, my mom got me a commodore 16 from a thrift store for 7 bucks. I was 11 or 12.. I went to the library and got programming books. None of them were about the commordore 16 exactly.. (i think they were for a 64 or a vic-20 its been a long time)so I had to wing it... plus I had no way to save. I never had any cartridges either.. I would just hook the computer up to a black and white tv that as in my mom's bedroom, turn the computer on.. write programs.. then turn it off and lose everything I just typed. One time I wrote a police record program and made my brother think I hacked into the police department. It was just a simple menu program.. if you pushed 1 then it would bring up a fake police record. not bad for a young kid.
I work with FPGAs, and porting the Gameduino to a more direct bus is quite easy to do. I'd be tempted to consider a Lattice ICE40 FPGA just for the open source development tools, but that might not work out depending on the memory design.
My first computer was a T61. The joys of Windows 7 setup... I'm not old enough to remember the 80s so I'm stuck in 2004. That doesnt mean I don't love building 90s/2000s desktops, I'm currently maintaining a ridiculously overspecced Optiplex GX620 as I don't have another XP machine, and I'm building a 98 system as soon as I have some clean floppy disks.
Discord for gaming is fine, and it's managable with a smaller community, but once it exeeds the low 3 digits of members it becomes too crowded. And facebook, well haven't been there for close to a year and have the feeling I'm missing nothing.
This is amazing...I have no knowledge about 8 bit computers since I started on an old dos dell from 1990...but something like this makes me want to learn
Learning to program in BAS8C on those old machines was/is a blast. The very first 8-bit computer I learned on was a TRS-80 Model I with Level 1 BASIC. While the BASIC itself is quite limited, it did come with a manual that was extremely readable and easy to follow. If you'd like more info, let me know.
I'm actually the artist that made that computer wallpaper that the first guest (the Australian dude) uses in the background. It's a weird feeling. Never thought I'd see it here, or out in the wild at all. In some tangential way, I've taken part in an 8-Bit Guy video. Neat.
The 'Australian Dude' has a popular channel called "Modern Vintage Gamer" and has written and ported emulators like MAME to different consoles at times. He's got a high quality channel. So you've probably been featured now on two influential UA-cam channels :)
Also for adding I/O as well. Taking the Z80-MBC2 as an example the ATmega32 chip on there gives you I2C, SPI, serial UART, basically everything onboard an Arduino. There's no denying the cost reductions and flexibility you get with a microcontroller.
The thing I miss most about 8-bit computing was being 10 years old.

It really was another time. In those days spirits were brave, the stakes were high, men were real men, women were real women and small furry creatures from Alpha Centauri were real small furry creatures from Alpha Centauri. And if you wanted to play a game on a CD you had to start by writing your own kernel.
Yeah, I was thinking the same thing. Also, "David asked me to design a board that could interface the C64 with the Gamduino. Here it is." I guess this is a product of a time when really using a computer meant understanding the computer (when it was possible to understand a computer completely).
I don't think you're quite aware how rudimentary a kernel for an 8-bit CPU needs to be in order to fit the project goals. For example the Apple][ ROM was only 4k That's 4096 bytes. Basically it has to handle serial and character IO by polling IO addresses, it needs to output to display memory, it needs cold and warm reboot entry routines that set up memory and the display. That's about it.
@@linuxgeex I don't think you're quite aware how crap I am at assembly. But seriously, I know it is nothing on writing a kernel for a modern machine. But it is non-trivial. I had a hard time in college trying to write an assembly function that took a number and changed the base. Even if it isn't a ton of code, it does require pretty intimate knowledge of the hardware and is difficult to debug. Not exactly a Saturday afternoon project. Particularly for most developers today who are used to high-level languages with visual debuggers and profiling tools such as myself.
I used a visual debugger for 6502 in 1984... it was called the Apple ][ monitor lol. But I think you're right in that the idea of what is 'difficult' these days has changed. Current generation is too accustomed to everything being handed to them on a silver platter, and a prize for last place. It's a great world they want to live in but it's hard to build anything that lasts out of snowflakes.
LGR had so much beige going on in that room, he was almost invisible.
Lindybeige would shake his hand. :D
Sara Thomas it’s a bit nice
Get it? Bit. Never mind.
LGR was in the video? Oooooh he mustve been the talking beard with glasses.
I was about to write the same comment (7:17 there's too much beige going on in your life LGR) before I looked at your comment.
Since LGR collects old computers and since old computers typically came in beige (especially business level machines like the IBM PC’s and compatibles and most Macs prior to the iMac G3 (1998). You can thank the Germans for this. Apparently, back in 70’s and 80’s when the personal computers first came to be and became popular, Germany (more specifically what was then West Germany) had enacted an office regulation law dating back to the late 70’s regarding workplace standards that required office equipment including computers to be light-value colors such as off-white, pearl, beige, light grey, etc. This office equipment color standard spread to other parts of Europe. Because computer manufacturers of business computers such as DOS/Windows PC’s didn’t want to have to build separate computer and monitor case colors for North America and Europe, they settled on boring beige or light grey colors as standard. The first DOS/Windows business computer to not come in beige/grey was the black colored original IBM Thinkpad laptop models (300, 700, & 700C). IBM wanted it to stand out so they insisted that Germany grant them an exemption which Germany eventually did but also requiring IBM to include a warning with the Thinkpad that it was not for Office use. They original iMac G3’s and 2nd gen. Powermac G3’ desktop Macs would also break free of the beige/grey color standard, though I don’t know if they too were given any sort of similar exemption or if the standard still applied by 1998. Now some of you will recall there are 70’s/80’s home computers in non-beige/grey colors, particularly black (such as the Sinclair ZX Spectrum and Amstrad computers) and that was because they were not business computers so they where exempt from the German workplace office equipment color standards.
Being born in 1985, these BASIC computers are a little before my time, but in high school I had a TI-83 Plus calculator that came with a nice thick manual. I spent a ton of time going through TI-BASIC and coding games and messaging apps. It was amazing and really got me into programming.
Maybe that is what is wrong with modern computers (even the Raspberry Pi) and why there is a wanting to go retro, the all but zero documentation that comes with them.
The last computer I had with decent docs was an NEC APC3, I was able to have some great time programming it.
I think the TI-83/84 plus calculators are pretty great for people interested in a modern 8-bit computer aesthetic. They have similarly limited hardware, a simple OS which starts immediately and shows little more than a blinking cursor, and they have a lot of documentation included with examples for how to program them in BASIC. You can also program them in assembly and directly write to any of the of the hardware registers. There are also "plugins" which extend the Basic version so you can call those commands from a BASIC program.
They also have a community around them which has been able to do very impressive things with the limited hardware.
Hell.. even simply just GAMES nowadays. I know it's a little hypocritical to say that I like to just get into a game from the start with tutorials and such, but I fondly think back at the (sometimes) extensive manuals games could come with that lets you ponder over every little thing the game featured, even though most of it you could figure out by playing :D Back in primary school a buddy's father owned a Apple Macintosh and he had SimAnt for it, which had a game manual that not only contained all the ins and outs of the game, but a full biology section (hundreds of pages) about ants and ant life, which subsequently made me learn more about ants and I photocopied the entire manual. Now it's just a simple "Quick Install Guide" or "Quick User Guide" and the rest is all just about playing. Even though nowadays you just want to just install a game and get playing, there's something about having extensive documentation going with it that you can study outside of the game :D
Well, the Ti-83 uses a Z-80, so a tad more modern (by one year) but used almost as widespread as the 6502, and fully intel 8080 compatible. It even runs Doom!
@@WickedMuis The extras were often included to hide the fact that the games themselves were pretty limited compared to their modern day counterparts. It's also tied to the distribution system - today games are "shipped" digitally, which is a Good Thing™ as physical media, packaging and shipping just add cost.
If you want extensive manuals and extras today you can still get them: simply buy the "Collector's Edition" and pay extra for the privilege.
My thing about 8 bit machines - they were completely knowable. Both from a software and hardware perspective. I knew my TRS-80 Model I so well - that when the characters started dropping bits I knew which RAM chip went bad. And that Tandy/RS socketed the RAM. Plus I knew enough about the Z80 CPU that I didn't use an assembler - I'd poke stuff into memory direct from poke/peek.
The other benefit was instant on as soon as power was applied.
"instant on as soon as power was applied." - I miss that too - the C64 had a cartridge slot, I had the Terminator game in there, awesome back in the day. Trying to make a phone call on my "smart" phone is a chore now as well as I have to dismiss so many ads before I can actually make a call!
Indeed. I'm getting pretty involved in my Tandy 1000HX right now making expansion cards for that goofy PLUS header. I realize that people do make adapters to go from PLUS to 8-bit ISA (XT), and I've even made one of my own, but you quickly realize that space is still an issue, so the best solution is to build your card straight onto a PLUS card.

Perhaps he should just talk to a Chinese OEM manufacturer, which would whip one up to Dave's exact specs in a short time, and produce it in quantity very affordably. That's what Chinese do very well, inexpensive mass production. Course one would have to keep a close tab on production, because they are known for lack of quality.

Up until then any access I had to a computer was one that had some sort of basic GUI and pre-installed games... it totally blew my mind..
I never did manage to get a tape drive for it, but I had a few carts that plugged into the back if memory serves me right...
Still nothing was more amazing than taking a game from pages of a magazine and (after painstakingly copying it line by line) fiddleing around with the code to make it do other things :) I remember I had some sort of ASCII adventure game, but it had no sound ... so I must have threw in like a hundred diff pokes so every time you moved it booped, and encounters had a little doo-de-doo kind of melody before they popped up ^-^ I was ssuuuuper proud of it too, I must have (over a few weeeks) re-compiled the damned game at least a few hundred times.... and even wrote all my addidtions on paper with annotations in the magazine I copied the game from XD

12:03 16 MB of memory are you crazy, no one needs that much. 3.5K Is all I need. :)
1 Bit of memory is all that a person may ever need
there will always be people that want more memory so put as much of it in as possible, maybe even allow us to use old RAM sticks to expand it :)
Of course this was meant to be joke. I recall seeing a 500 meg. Hard drive at a software etc thinking who would ever need that much storage when wordperfect ran off of 2 floppy disks. 🤣
I remember the first time I booted up a IBM compatible 386, with it's massive 45MB HDD. Coming from a C64, young me was blown away at the thought of having most every game I owned on hard drive, with no need to swap or flip floppies.
Cue 1997 when we finally left the C64 and 386 (we used both side by side as there was a lot of documents on the C64 we couldn't transfer without a lot of work) behind for a 450MB HDD AMD K6-2 Win95 machine. Then Baldur's Gate came out with it's 2GB size and 5 CD install...
And yet we have 6969696 KB of RAM (6.9GB) in computers and even phones!

The RC2014 is a Z80 based computer designed in 2014. It's actually pretty good and can use a Pi zero to drive the screen and keyboard etc. Take a look.
I wish I lived when 8-bit computing is "mainstream" and you could manually adjust registers on the fly. These systems made you understand what was happening and it was simple enough to learn through playing with it. I wish this because I would have a greater understanding of why things evolved to what they are today and a greater appreciation for the modern hardware that seems so abstracted away from me in the modern Windows PC and even in the Linux world to a point.
The VIC-20 was my first computer. I got it for Christmas but mum & dad gave me the manual to read in advance and I read it cover to cover about a *million* times before the big day - it was a great manual! I was completely hooked from that point on. :)
"Best Seller!! Over 30,000 Sold Worldwide!"
Wow. That really takes me back.
You can get relatively cheap FPGAs (sub $9) that'd be able to handle VGA no problem and maybe some extra I/O stuff on top.
Keep in mind that $50 may be pushing it in terms of unit cost. The WDC 65C816 (6502 CPU) is $7 alone on Mouser, an FPGA to handle VGA will be another $7 - 12 (i.e. Spartan-IIA Xilinx) and the DRAM will run you around $2-5 (Digikey: 1MB, 8Bit Parallel SRAM). Then you'll need circuitry for misc I/O, SD card interfacing (prob another low level FPGA) and interfacing to the CBM Serial bus which is another $10 due to the FPGA used. The power circuits will run another $5-8 (assuming you want to power it from microUSB) and the board required (you'll be needing atleast a four layer board) assuming 5" x 5" will run $20-25/unit (PCBWay: 4 layer, 6/6mil rules).
Assembly will also be potentially costly depending upon volume. If you want to hand assemble, you'd need a reflow oven, hot air tool, solder paste, as steady hand and a stencil. Hand assembly is cheap, but if you go to volume (say 50 board run) you're looking at ~$15 - 25/unit (PCBWay: Turnkey Kitting, ~100 SMT parts, ~5 TH Parts i.e. connectors).
$100 is definitely on the high end, but $65-75 / unit is probably more realistic.
But this is only back of the napkin math, so there can definitely be some cost savings abound.
It'd definitely be a challenge to do the interface over an 8 bit parallel bus whilst aiming for the goal of everything being near bare metal accessible to any coder (as opposed to something like the VIC chip using its VRAM straight from the main data bus to which the programmer can just directly address VRAM instead of obfuscating it through the 8 bit parallel bus).
When buying in bulk the price per unit drops, and considering he is open to using modern components these costs are a bit nuanced but you bring up an (unfortunate) reality.
He showed his GameX selling something like 50 games a day. I have idea insight into his numbers, but I'd say a run in at least 100s of units. 50 would be big for you or me, but check out his subscribers! And two sizeable channels giving adivice here. That's a huge audience. I'd guess easily 50 a month, or per week.
What I miss about 8-bit computers:
I miss feeling in control of my computer. Maybe it was slow. Maybe it was limited. But it was mine and it didn't do anything(literally nothing) that I didn't tell it to do. I miss the immediacy of the computer following my instructions(How many times have you double clicked on something which didn't respond immediately despite your computer being thousands of times faster than an 8-bit computer). I miss being able to understand what my computer is doing and why(I don't even know how many millions of lines of other people's code is running on my computer nor do have enough time in my life to read all of them even if they were available). I miss being able to run programs without internet access. I miss software being designed specifically for my computer instead of being forced to buy the computer that the software vendor asks for. I miss being independent of huge corporations sending me updates that do God only knows what or why. I miss my computer not getting slower as it ages(How many times has someone told you to buy a new computer because yours is running slower than it did when you bought it). I miss being able to write and run my code without needing multiple devices(development board, cable, software tool chain, and computer used for code editing) which all have to be compatible with each other. I'm the kind of guy who leaves specific wrenches and screwdrivers in places where I'm going to need them so that I don't have to go looking for them later and it irritates me when I have to scrounge together a development environment to alter the behavior of a "brick" which I haven't touched in 3 years. I miss being forced to get creative while adapting my task to a set of known constraints as opposed to the modern paradigm where you just write a logically sound(but perhaps inefficient) program and throw resources at it until it works acceptably.
What I don't miss about 8-bit computers:
Low capacity floppy disks and the difficulty of moving data from one computer to another.
This right here
Bunch of pedantic bs
@Jack's Model Railroad , that's true and they are so cool for what they were built for - simplicity. Modern computers are made for enormous complexity, and they can be used in a very user-friendly way or get dived into extremely deep and complicated engineering. Let's say that back with 8-bitters we behaved in simpler ways, and expected much simpler stuff. Perhaps we don't miss 8-bit, we miss ourselves and simpler times. Because - less is more, keep it small and simple, DIY, small is beautiful... etc. Human being is cursed with finding new ways to get his life complicated, comforting oneself that it somehow makes life easier. Oh, well, tragicomedy drama.
A simple OS and programming language - that's what we don't have anymore.
Just imagine what could be done if a "accessible" OS was running on "modern" hardware ....
The fact that as I take my classes, I slowly begin to understand what he's talking about more and more is exhilarating
I definitely understand your love of that first 8 bit computer. In my case, the gateway drug was a TRS-80 model 1. Within months, I knew what every single byte in the memory was for and as every device on the system was memory mapped that meant I understood EVERYTHING about that system. Even when I moved up to the disk system extension I was still comfortable with each and every part of the system (though, my investment was about $1500.00 in 1979, I was quite as comfortable with the expenditure). Sadly, with today's systems, I don't even have an inkling about what is going on in the sound card (the trs-80 had a relay to stop and start the cassette recorder, if you switch that on and off quickly enough, it made a sound .Hi-fi, it wasn't). Even at the age of 79, I do still enjoy programming the latest chipsets but the nostalgia for the 8 bit days is intoxicating.
Whatever you do, please make it open source/open hardware. People will help you with a lot of stuff if you do it that way.
I'd be surprised if he did not make it open source but you never know
@Michael Dina Yes, but asking for help doesn't necessary means "make it open source". I.e. I can ask for help, and in the end, implement things like I want, with closed source, based on user's ideas. Which is what it looks like, but let's hope it's just my misinterpretation.

If you're using an FPGA for video you should be able to synthesize dual-port RAM which would allow you to directly access it both on the C64 side and the video driver itself. You'd need a voltage conversion on the C64 side which just requires a few extra chips (like an Everdrive)

I'm guessing 8 bit guy is the same age as me as he went through the same vic20 experience initially. I wrote so many games in a mixture of basic and machine code (no assembler then) to shift graphics around.. Annoyingly I chucked the tapes a few years ago, I would do like to see my creations (of a 14/15 year old me) again. I then migrated to the atari ste and released a few games on that and then the gp2x games console. I'be been lucky in that I'm an embedded software engineer since the mid 80s and would never have got into this without my parents helping me to buy that initial vic20. I owe them so much and thankfully they lived long enough (my father died a few weeks ago at the age of 90 from pneumonia, possibly triggered by this covid-19 virus, my mum died from cancer 3 years ago, aged 81) to see me have a successful and interesting career. I'm now 53 and considering retiring in 7 years but feel I will miss messing around writing software at a low level once I do that. Dunno why I had to post this but thought it was a good placeholder to say thanks mum and dad for being such great parents and I miss you.
For sound capabilities I would highly recommend Yamaha's OPL FM synthesis. It's instantly recognizable, nostalgic, and sounds pretty darn good.
The benefit with OPL and FM synthesis in general is that, unlike the SID, it is purely digital and has no analogue filters, which dooms the SID to either be recreated in custom silicon, or faked in software.
The OPL chips such as the OPL2/YM3812(used in AdLib and Sound Blaster), and the OPL3(used in Sound Blaster 16) and their clones can also be had for a dollar or two, and I know of several people designing and building brand new Sound Blaster compatible cards, as chip stock can still be found readily online, but there's more to it than that.
With OPL, you can recreate the whole chip in an FPGA and have it be identical to the original in every way, and there's already code available online to do just that. OPL and FM synthesis in general, unlike the SID, is purely digital and has no analogue filters, which dooms the SID to either be recreated in custom silicon(absurdly expensive), or approximated in software(all SID chip replacements use this method still).
The digital to analogue converter that usually paired with said OPL chip runs at a nonstandard frequency alongside the OPL, with a master clock at 14.31818Mhz and a sample rate of 49.7159KHz, which may prove a little more odd to replace with modern parts, but far from impossible.
Nevertheless, it shouldn't be too difficult to implement and because of the nostalgia and past popularity, it would have a much greater following and ease of use as well.
It might prove hard to take full advantage of OPL with the 65816 when multitasking, if the clock speed is as low as the original processors.
Here's an example of some code I found for an OPL3 (YMF262) chip replicated in an FPGA: github.com/gtaylormb/opl3_fpga
OPL was definitely a great sound, I saw that fpga project too and was amazed. I'm pretty sure my Tx81z has a similar chip.
Why not a ym2612? Personally I like the sound of that chip compared to the OPL ones, at least from what songs i've heard that were made between the two
@@jlewwis1995 Oh, so you would like the computer to be a bit like the Sega Genesis
The most challenging aspect of the Kernel will be dealing with the 64K blocks of memory. Yes the 65816 can address 24-bits, but moving across the 64K chunks can be quite tricky since the ALU is 16-bit (a simple jump table doesn't cut it). There are already solutions to this if you poke around the various forums (6502.org, etc.)

So it’s like x86’s real mode with segmentation?
@@colejohnson66 x86 segments can start almost anywhere and overlap each other. Segments of 65816 is just all memory divided into 64K chunks. So you can run a normal 6502 or 65816-enhanced code in a segment, but if you need more memory, you need to long jump to another segment (or perform a long read to reach data there). Not too bad, actually, 65816 is very simple easy to learn device, just like 6502.
@@colejohnson66 Same concept, different implementation. Instead of an offset that gets added to the address like x86 there is an 8-bit bank register which specifies which 64K chunk you are working in.

I when way above the requirement of the assignment, and I did get an A, the instructor wrote "fine" on my report. I keep that report, and have shown it to other instructor at the schools I have been an adjunct at. At least one has said it would be a great computer for people to learn assembly on.
I painted a 4116 chip on my school bag in 1987 with silver metallic paint. Since it's much more difficult to paint a 6502 and I did not have a broken CPU chip, I painted that 2 kB memory chip and glued a real 4116 chip under the enlarged painting.

just a question. i'm not sure if that Dream Computer is to connnect to a C64 (like that prototype) or a Stand Alone Computer.
@@napomania He's describing a stand alone device. The C64 is only for prototyping until the kernel can take over.
I think for me, the appealing aspect of 8 (and 16 bit) computers was the simplicity, yet complexity in terms of what you could do with them (of course, by today's standards these are nothing, but back then, you could do some pretty cool stuff, and you didn't have to worry about things like updates, viruses -- at least not as much -- and other things you battle with today, software compatibility, drivers, security, etc). They were a simpler computer, but a more fun experience IMO over what we have today. Granted what we have today is great, but as computers got more complex, so did the upkeep (so to speak) of them.
If you’re using the 65816, something you should know is that bank zero contains the stack and 16-bit interrupt vectors (and since they’re 16-bit, the interrupt handlers are expected to be in bank zero as well). So for bank 00, you’ll have to do some odd stuff where the bank is part RAM (for the stack) and part ROM (for the interrupt vectors and handlers).
Source: W65C816 Data sheet + “Programming the 65816” by David Eyes / Ron Lichty
Snapp Which is another typical low end FPGA or CPLD job.
John Francis Doe ?
I thought the stack was page 2 on the 6502, and has its own high-bits register on the 65816? Oh! You mean the first 64K, not the first page.
Why not copy a ROM image to RAM, scattering segments to various addresses if it is discontinuous, at reset? You could use a cheap serial flash chip and be cheaper than a full bus interface.
John Długosz That sounds like more work than should be needed.
The location of the interrupt handlers can be anywhere within bank zero. The interrupt vectors that point to the handlers have set addresses. For example, the RESET vector is located at FFFC,FFFD. For the general IRQ vector, it’s located at FFFE,FFFF in Emulation Mode and FFEE,FFEF in Native Mode.
That’s not hard. I’m designing my own 65816 system and as I come from an Acorn background it’s going to be somewhat like a BBC Micro/Master memory layout. So bank 0 has a 32K static RAM and 2 x 32K EEPROM devices. The reason for 2 is 0x8000 to 0xBFFF was paged ROM (it could support 16 “sideways” ROMs) and 0xC000-0xFFFF is for the OS. The 32K OS is two 16K banks switched by the emulator pin (because the Acorn OS has vectors for OS calls which clash with the 16 bit vectors). Finally the edge connector has a ME line which if pulled low deselects ALL of the onboard memory. It’s taken about 5 TTL chips to do this.

what I miss about 8-bit computers? It was the best time period of my life.
Well, since you didn't ask me, I'll share anyway... What I missed about the Commodore 64 was the excitement of new things. Amazing things that were never done before. From games to office productivity. Everything - from the beginnings of email to BBS's to cool games. Everything and everyone was on a race to the next great idea and there was no shortage of them either. We simply don't have much of that anymore. Sure, graphics are better - sure, sound too - but in the end, most of everything we have today is just an improved version of these 80's developments.
The fact that you have seen the c64 kernel source could be a problem... You had better hardcore CYA to make sure that none of your code is at all similar to c64 code otherwise they could make your life extremely difficult with copyright issues.
And the company in question has a long and sordid history of copyright lawsuits. in fact possibly the longest and most sordid history in history.
Commodore is dead, in the ashes, it went bankrupt, they wont sue him
I thought about that too, Daniel. Right out of an episode of "Halt and Catch Fire".
I otoh haven't seen the C64 ROM code, but I've seen the Apple ][ and ][+ ROM code (because they were published openly like IBM's). Of course, that's only 2K, and it's very easy to NOT do the same thing.

Alan Kay, the inventor of Smalltalk is one of the people who's been working on this.
Google for STEPS and Alan Kay. He had a demonstration system that was based on a bunch of ideas, constraint programming, custom languages graphics and other concerns, in fact including a system for generating new languages as needed.

I spent my entire childhood as a TRS-80 Coco guy, fighting the "dark side" as represented by all my Commodore friends, and here we are, 35+ years later, and between you and Ben Eater, you guys have me happily and enthusiastically joining that dark side!! UGH.. My 12 year old self would be so ashamed.. :-) Keep it up.. I look very much forward to buying one of your computers once they're ready! Actually...

7:15 Clint's whole section in this video is exactly what I love about retro hardware and is something I've really been struggling with as a game developer. I actually have a license to work on modern hardware as an indie but still I feel that there's no limits with the modern hardware and thus I feel I'll end up making a game that feels just like every other game or worse will just not be that interesting or fun because well "I could do anything, so I did this"
Richard O'Brien, the playwright behind the Rocky Horror Show (1973) and Shock Treatment (1980), has a quote that I think really applies here and has become the basis of my mindset as a developer "Limitations inspire creativity", this comes from the person who had to rework their movie to be recorded completely indoors after a writers strike caused outdoor filming in America to no longer be an option so they rewrote the movie to take place in a TV studio where all the locations were no represented as shows on the channel.
This is a lesson I think many developers could learn from nowadays, sure the AAA companies won't but that's okay, indies could as those limitations are already there in other ways so why not make a game within them instead of trying to reach outside of them. I've seen various "retro" looking games that didn't adhere to the limitations of the old hardware and that just made the game feel off to me as I knew that's not how the old graphics looked so it made the game feel surreal. For some games that was the point and those games used the dissonance to their benefit but some were supposed to be convincing and just weren't.
So that's what I miss about 8-bit computers, if you tried to fly you hit the ceiling and reality would come back into perspective instead of letting you clip through the roof and off to space like modern hardware does. In non-metaphorical terms, it actually restricted you to adhere to it's limitations and if you wanted to escape from them, you had to be more clever and even then it still kept you down to Earth.
I wonder if Bill Herd, the former lead engineer and creator of the C128 might be able to help him out with stuff. Bill did guest star in the Commodore History series in the Plus4/16 (TED machines) and C128 episodes and he's intimately familiar with all the Commodore machines, likely especially the 64.
EDIT: Bill also knows what the VIC II did and didn't do and might have input on a good replacement.
Seeing as how the current model sources chips that are not available and is five hundred dollars this did not age well
Will await your upcoming retro platform.
A YM2608 or an OPL3 chip would be cool for a sound chip.
Second! Or, failing that, an ESS1869 or similar.
I think that it would be no brainer to not go with OPL or is older brothers. They are still made.
I would actually prefer subtractive synthesis. The SID even had analog filters. With FM you tend to get those cheesy casio-keyboard sounds. But yeah they can be charming too. I would really love to have both FM and subtractive, but if the whole thing is to cost around $50, that might be hard.
@@letMeSayThatInIrish At least YM2608 is a very capable FM synthesis chip. Nowhere near the "cheesy casio-keyboard sounds" category.
@@letMeSayThatInIrish the YM2608 has a YM2149 core in it that has 3 square wave channels like the SID chip, it also has 6 four operator FM channels that can be tuned to produce some realistic instruments, it includes another 6 built in drum channels and one sample channel. it also has GPIO.
I love legacy relics of the golden age of personal computers that required an artisan to operate i remember my at and xt computers up till 16 and 32bit computing blew the minds of us nostalgic geeks... these machines required skill or hidden talent to operate.. i learned QBASIC aka quick basic when i was 11 and got ms dos 6.22 and windows for workgroups wfw 3.11 for my birthday
"Limitations Breed Creativity" - Adam Neely

It sure does breed creativity, but only up to those limitations.
Never a trued word spoken. Been there. :)

I just want something game artist friendly for development and easy to port to modern platforms. Good sound card would be rad too.
Also, I don't want to use facebook.
Even a not very good sound system could be good enough.
If you want low cost, perhaps making the video character fetching system fetch a few extra bytes during retrace could give you the audio DAC values. 3 16 bit values would be more than more than enough to make sound clips play.
how about IRC or Riot.IM?
Just ordered an X16 from TexElec so i'm re-watching the entire playlist, can't believe it's finally here!
What I miss about 8-bit machines was watching in amazement that programmers could overcome the extreme limitations placed on them to create some real masterpieces. That's why I'm a big fan of the Atari 2600 & IBM PC demoscenes.
The greatest unpopular micro, the Atari 800L.
Aww man I still really want one buy I could never find a good one.
Tramiel had something to do with it, the same ideas appeared later in Amiga machines. What a great time!
The "floppies were so slow" was solely an issue of poor design by Commodore and Atari (weird both companies made essentially the same error). My first PC was an Apple IIe and thank God (or rather Woz) it had a very fast floppy drives and 80-column support out-of-the-box. That made programming and things like word processing (Apple Writer IIe got me through all my high school writing assignment) very nice. While the Apple IIe suffered when it came to graphics and sounds, Woz's efficient design that allowed for a fast, cheap disk drive and 80-columns made both ubiquitous. Those two base features kept the Apple II line alive long after it had any right to be relevant. Many game devs used Apple IIe's as their "workstations" (sometimes with custom IO boards in a open Apple II slot) and cross-compiled to the "more powerful" Atari and C64's.
Yeah, I never though about floppies as being slow back in the day with a ZX Spectrum clone. Compared to 5 minutes of loading from a tape, 5-15 seconds loading from a floppy was a breeze.
Not so much poor design as rushed design. The release date drew close, and they needed those floppies working with great urgency.
yeah floppies were fine since everyone modded the C=64 to make them run 5x faster
I did both an English minor and Comparative Lit minor at University on Wordperfect for Apple IIe. Green monochrome monitor because my parents wanted to minimize game time. Although come to think of it, it needed an "80 column/ 128 kb RAM card", -not out of the box!
Vyl Bird: You are quibbling over the sense of "design" being used ... the original design concept was better than the final delivered design, as shown by the much better C128 serial disk interface, which is much like what the C64 would have been if the CIA's had been able to do hardware serial I/O on the serial bus.
The problem with using stuff like the Gameduino is that you very quickly end up with a very powerful graphics processor being scripted by a very simple applications processor --- you get completely insulated from the platform and might as well be writing in Javascript! Also, the Gameduino is anything but cheap, costing about two to three Raspberry Pis.
It's possible to bitbang VGA using an 8-bit AVR, at a fraction the price, although that's probably not suitable for game graphics, but it shows you don't need high-end electronics to generate modern video. If you aim at VIC-chip like capabilities you can probably replicate the same functionality using a slightly higher-end processor without going for a full-on high-end graphics chip.
I think if he agrees to use a Spartan FPGA, he might as well implement all the chips gfx/cpu/audio in that FPGA ;)
It only temporary solution
@Omega LUL it is, if only people would watch it
ESP32 as VGA generator? ua-cam.com/video/qJ68fRff5_k/v-deo.html

I get that feeling with full control on old machines. It did what you told it to do and if it did something it wasn't supposed to, it was more than likely your own fault. And wringing every inch of performance out of that C64 or old PC by tweaking just felt great.

Reminds me of the time I played Theme Park on the PSX which was kept on for days until I finally bought a memory card. Childhood memories.
I was impressed by planet x2 / x3 but this is some next level shit. Man gonna write his own kernel.
Woodythehobo absolutely true. It is mind blowing
Kernel writing isn't that hard , its like falling out of a tree once you broke your arm , your back in the tree to brake the other arm ;)
It's a program , think simple memory and time shearing thoughts
Is quite impressive that he’s doing that I’ll give him that but I’m 13 and I’m actually working on a small kernel of my own :/ but still he is going beyond that and putting it in his own hardware, not only that he’s doing it only in assembly, I’m doing it in assembly and C which makes it much easier. At this point idk why I’m writing this lol I’m fucking stupid
Writing a Kernel it's not that advanced, it's a 3rd year course in my career

One of the negatives of 8-bit computing noted here is one I miss: the long loading times, especially from cassettes, especially the 1st time loading a game. The anticipation of how the game will be. I actually miss it so much, I turn off Turbo Load on my emulators.
I personally would have gone with a Motorola 68000 CPU. The 68000 has a flat 32bit address space, hardware multiply, it's simple, it has a very simple and clean instruction set, there's better C compilers for it. Every register is 32 bits The 6502 is kind of tedious
but i guess he wanted assembly language compliance with 6510; most of mainstream 8-bit computers used a 6502/6510 cpu
@@alerey4363 I suppose so. I'm not sure why you'd want to stick with 8 bit, though. You could get a C64-like experience with a significantly faster, easier to use, cpu for the same price as a 6502
Because the m68k is not even close to the fun and elegance of a 6502 or derivatives. Having coding for both of these systems in the past, one can see why m68k died the way it died (not even spark succeed, and spark was based from the m68k... but to be honest, the old good computer era died with the m68k...), and the 6502 heritage is still in use as of today (arm). Of course if you don't like the 6502, you probably like the m68k. To each it's own.
@@terramap2902 it's pretty well accepted that the 68000 has one of the most human-friendly ISAs. I moved from coding the 6502 to the 68000 in the 80s.
The 68k was enormously more developer friendly. With the 68000, ALU operations have a nice bag of addressing modes to pick from. It makes a smoother flow writing code. I do want I want to do in one instruction rather than four or five.
Not to mention the 6502 barely has any registers. While the 68000 was ahead of its time with a large number of general purpose 32bit registers. Naturally this makes coding the thing more pleasant as you spend less time juggling the registers and/or stack.
On top of that, the 68010 supports privilege levels, so you could make a proper OS, which makes it more interesting from a comp-sci point of view, some of the 68* series also supports memory mapping
Well.. it seems that [your dream computer] != [8-bit guy and the rest of us dream computer.]. Not trying to begin a holy war between dead architectures anyways (well.. not so dead considering m68k->spark, 6502->arm, z80->x86), so i'll stop here. Let's just say, we agree to disagree :)
(tho, my dream computer is a 6502 based machine, with 16 MB ram, multiple graphics modes, raster interrupts so video chip with non fixed RAM (so you can move the data anyplace inside the main RAM) is a must for me, at least 64 multicolor sprites, MIDI sound would be good, but depends on the audio chip he will put in there, and the standard ps2 port is not a bad idea... i think the RPI serial port can also be a good idea to thinker with, but i don't know if an internal sd card would be a good idea due to licensing involved...

The Acorn Atom was a beautiful computer to use, in its day.
The ability to code assembly language into BAsic programs, which could have offsets and macros, so the code could be saved to tape , and then reloaded into the required locations.
Or the code could be compiled in site and then called.
And the indirection operators ? ! for byte and 16 bit word access to memory directly.
And of course the expansion bus was compatible with the mprevious System 3
And it was the foundation for what would have been the Proton, but in fact later became the BBC MICRO , *sigh*

Immediate gratification when you turn on an older system. It just brought up what you wanted, and fast. Same for the programming, no layers to access or go through to do low level bit manipulation. Great video!
Wow.. You have the happiest intro I have ever heard!
While yes, the statement on the 65816 is backwards compatible is indeed correct, some older 6502 games used illegal opcodes, something that doesn't work on the 65816 (were overwritten with the newer opcodes).
WDC produces the 65C02, not the 6502 unfortunately for us :(
Well, since this would be a new system, it wouldn't run old stuff for C64 anyway, so that backwards compatibility wouldn't be an issue.
No VIC & no SID = not a C64. He's only using it as a general guide for architecture design. Make a C64-like machine freed from some of the more annoying limitations that don't "breed creativity"
@@zerobyte802 I'm saying this less of for backwards compatibility with C64 games, but more in the sense that some illegal opcodes are really useful; some do two intensive instructions at once, and save space in the process.
You should take a look at TI graphing calculators, they're basically the closest mass produced modern equivalent to old school 8 bit computers in terms of closeness to the hardware and their limitations and I know a lot of people who first learned to program on them. It's usually relatively easy to start doing assembly on them, the memory and the speed are somewhat limited so you have to take that into account when writing programs, and they typically come with pretty extensive user manuals, plus you can hookup a TI-Keyboard to get a closer experience.
The things are still $100 USD in stores and the 83+(!), the gold standard in math graphing calculators, can't do audio without sacrificing every cycle of the CPU to output to the 2.5mm port! I loved them in school simply because the Gameboy was relevant at the time and it's not like I had anything better to do... "Oh yeah, watch this date rape video" No thanks, I'll code my own rooms for a Doom engine I translated from the TI-85.
@@DoomRater True but can you think of any other modern 8-bit system with as much of a community? Most modern single board 8-bit computers are little hobbiest things and don't have anything close to the community you see for TI calculators. They're also significantly cheaper used, as little as $20 for a TI-82. The newer color editions bridge the gap somewhat between 80s computers and calculators. Granted it lacks dedicated sound hardware but it's theoretically possible to set up a DSS situation or even wire in a SID with a microcontroller
Okay okay, second hand market rules, and I own a few calculators that way, but how many parents know to do that? The color systems are something to behold, but my research is non-existant on them. I don't really know what they're capable of right now. Just keep in mind we have to get this knowledge to parents of kids in high school who are going to need the industry standard.
@@DoomRater The 84 Plus CSE can do some clever stuff with audio but the 84 Plus CE is still pretty new and nobody has built a DAC for it, that said the 84 Plus CE has basically the most powerful 8 bit chip on the market right now (eZ80 48mhz) so it certainly wouldn't be short on cycles running a dac.
I never should have sold my TI-85!
The thing I like most about 8 bit computers is the fact that I am sitting in a modern world with modern, cutting edge technology, using what was once considered those same modern things. This is why I like the CRT/composite, floppy or cassette drives, and all the things that are so hard to get, because I enjoy the thought of using something that was once cutting edge.

You really need a 100% custom kernel, otherwise Cloanto will sue you even if you license the old Commodore ROMs. Even mentioning that you looked at the code might get you sued, even with a 100% original kernel, since Cloanto is primarily a lawsuit troll company.
Likewise, the Commodore BASIC v2 or v7 will be copyrighted still, by Microsoft. It may be better to implement FreeBASIC or OpenBASIC if you're going that route. Both are derived from QBASIC, have available compilers, and actual graphics routines.
Going from there; if you're using an FPGA anyway, it can drive the VGA output I believe.
For IO, is there a reason to choose PS2 peripherals? Why not pick up a USB controller, since USB keyboards, joysticks, and mice are common now? I don't think I've had a PS2 connector on my last two or three desktop builds, and I certainly haven't seen a PS2 keyboard for sale in ages, only USB.
How will sound be handled? Something like an OPL chip?
agreed, set aside some funds to see an attorney who has a track record specializing in these things before getting too financially invested. all it takes is a request for an injunction to shut you down at the very least, and at worst competely drain your resources to zero. not sure you would be able to afford a six figure litigation team to fight something they have a case for.
There's a difference between being compatible with Microsoft Basic and shipping with Microsoft Basic. Shipping with a FreeBasic but being compatible with Commodore Basic v2 would be by far the safer way to go.
Good luck suing for copyright when 90% of the work is original.
tenshi7anegl: They can still sue.

If you want to learn about "computer architecture" you might as well pick any ARM SoC and go through the datasheet for it. Proper buses like pci are rare so it's mostly like an old machine with a better CPU running it.
Those datasheets are monsters though. An old Z80 is ~200 pages. Even a simple ATmega328 μC is almost 700 pages. If you add all of the design and relevant app notes this could easily top 1k pages. That's no small task for the inexperienced to tackle. There is a ton of assumed and contextual information in modern datasheets. Between the sales terminology, inflated metrics, and intentionally omitted info it's no walk in the park to learn on modern hardware in my (recent) experience.

In the early 90s, my mom got me a commodore 16 from a thrift store for 7 bucks. I was 11 or 12.. I went to the library and got programming books. None of them were about the commordore 16 exactly.. (i think they were for a 64 or a vic-20 its been a long time)so I had to wing it... plus I had no way to save. I never had any cartridges either.. I would just hook the computer up to a black and white tv that as in my mom's bedroom, turn the computer on.. write programs.. then turn it off and lose everything I just typed. One time I wrote a police record program and made my brother think I hacked into the police department. It was just a simple menu program.. if you pushed 1 then it would bring up a fake police record. not bad for a young kid.
I work with FPGAs, and porting the Gameduino to a more direct bus is quite easy to do. I'd be tempted to consider a Lattice ICE40 FPGA just for the open source development tools, but that might not work out depending on the memory design.

Learning to program in BAS8C on those old machines was/is a blast. The very first 8-bit computer I learned on was a TRS-80 Model I with Level 1 BASIC. While the BASIC itself is quite limited, it did come with a manual that was extremely readable and easy to follow. If you'd like more info, let me know.

Why not ask Linus Torvalds for the kernel part? He really liked the 6502.
I always found your original "No fpga/microcontroller" point amusing as those things are really handy for implementing glue logic.
Also for adding I/O as well. Taking the Z80-MBC2 as an example the ATmega32 chip on there gives you I2C, SPI, serial UART, basically everything onboard an Arduino. There's no denying the cost reductions and flexibility you get with a microcontroller.
