Even though many of the computers in my collection are hard to find, or no longer manufactured, only one can claim the title of being the only one of its kind to be made.
I can imagine the episode now: Ahhh, the Propintosh. The best computer you've never heard of. Where did I get it, you say? Well... that's a different story...
I remember doing something almost exactly like this. At the time, DRAM was dropping in price in the sub MB varieties, so I ended up buying some 3.3v memory, dedicating one of the cogs to being the memory arbiter and then with a combination of dropping down to PropASM and learning how to use 74x logic to keep the memory refreshed while the cogs were rotating, I learned SO MUCH about how computers dealt with memory and how it was mapped. However, I am super jealous of your 15 year old harware skills. I didn't really get started until I was 25, but seeing what you did with that is mega impressive :D
i was thinking of doing something like this but i only know how to program in python, so and OS is gonna be hard...then again i wanna try using micropython to build the computer(just a box with a small lcd screen, keyboard,mabey mouse since what i am building is a text based operating environment, a pyboard, charger, and i need to know if it can even use input arguments, because i have looked all over the internet and could'nt find one damn video using inputs on a pyboard. Please anyone help
Honestly, I think it's really cool you turned a limited microcontroller into a computer. I always love seeing tech stretched to its limits and taken outside the bounds of its intended purpose.
Ok this is actually pretty cool! And I have the same problem with commenting my code as well! I have been trying to get out of that habit but like a few hours later I end up not bothering and telling myself "I will comment it later" and never do haha
At least you give your variables proper names. As recently as a year ago my logic was "Why find a code minifier, I'll just do it myself", and hence a bunch of single or two-letter variable names. Suffice to say I've learned my lesson.
I head to programm in C in one course for one semester. Well, it pretty much forced me to comment anything. Especially when you had to programm for the professor, or when you had to work in a 2- team to wirte a program. It was hard for me to learn that, but when I do an Arduino thing, I comment now more and have a way cleaner style of writing ( it's still very very shitty though). But before My programms where like shit. Style was bad, no comments, and whenever I dropped something for a few weeks, it was hard to come back. And code was simpel back then, as it got slightly evolved, you couldn't figure out shit. On my recent project, that I dropped for a couple of month, I am now very grateful to myself to have them. Was way easier to figure out, what the fuck I was doing :D But yeah, without the preasure of the professors I wouldn't have learned it...
He should start a patreon page for the the propentosh 2, people donate and he will make a better one. Maybe if he got enough money, he'll start mass producing it, starting a retro business.
Reminds me of the 4 bit bus computer I built over a weekend as an assignment back in 1987 using a 74181 TTL ALU, 3 x shift registers and 2 x 16 x 4 bit word 7484 TTL RAM chips. It had a 555 timer clock running a pair of 74193 controllable UP / Down binary counters and all display was via 7447 TTL LED numerical blocks. I still have it somewhere and it could perform 64 mathematical functions so long as the number didn't exceed 15 (well 16 if one counts the "carry up" flag pin on the 74181). I'd built a basic CPU functionality in TTL, which is what engineers did before processors were invented. Macro coding by hard wire with a pretty simple machine code instruction set: The 3 x shift registers were for Register A, Register B and Command Word Register with the resultant answer ending up in Register A. The programme bytes consisted of the lower 4 bits being the numerical content and the upper 4 bits being the instruction word. All built on strip board with lots of Kynol wire.
I absolurely love this. In high school I did similar with a 6502. Today I am embedded at software engineer. Projects like what you have created absolutely fascinate me. You took something with limited capability and through creative thinking, you made something amazing as well as useful with that basic interpreter! Prop(ellor) to you man! Totally gonna follow you channel. I like to do/make the same for fun, challenges and for the "hell why not" factor ;)
This is without a doubt a beautiful passion project. That's what makes this so special. It's not some Rasberry Pi stuffed into a retro looking design, it was built from the ground up. Awesome work.
Honestly, for the speaker, I just never got around to it. I mentioned in the video, there were plenty of things I was planning on adding further down the line with this computer, like the speaker, a TTS chip, wireless serial communication, IO ports, an SD reader, and even a receipt printer. I just came to the conclusion pretty soon that no matter what I did, the device just wasn't going to be powerful enough, and dropped it before I had the chance to make those upgrades. As for the color display, (at least when I was building the thing) the largest color smart display was something like 3 inches wide. I could have used a larger TV LCD and powered it off of the Propeller's RCA output, but that would have pretty much defeated the purpose of having an external display, since the TV would have used all the memory.
I also imagine migrating to a color display would have been mean on the RAM limitation. Some people ask why EGA/CGA existed and we didn't go straight to VGA and "millions of colors". Long story short, memory was a limiting factor, and being able to define a color in just one byte was almost a necessity in some applications like spreadsheets and charting.
pretty much thought the same I thought of "why not use one as gpu and another as cpu" the "gpu" can likely also proccess the input, since it doesn't need to actually compute much
With a well-positioned camera. You can see the flashes from the panel, as well as the slightly off center display and the visible pixel outlines, meaning it's recorded with a camera.
This chip is actually very similar in specs to the microcontroller that handles by Nerf primary, my FDL-2X. It handles motor speeds, select fire, and power management features. Let that sink in for you people watching this. That's how impressive this build and its software are, the creator of the Propintosh literally programmed on a platform that's so low-spec, it's only really ever used for very simple robotics work.
External SRAM chips on an I2C bus, with a dedicated core to handle memory management would sort out your space issues quite effectively. Possibly add a bit of "slow memory" on top of that in the form of an old MMC card (easy to handle in terms of I/O, as well as nice small code size for access and read/write ops). Other than that, great little puter dude, well done! You nailed the aesthetic! Subbed!
This reminds me of coding in TI-Basic on my TI-83+ in high school. I loved making text based RPGs, and at the time, I learned the coding language pretty thoroughly.
Hello. I really like this project. I really like how you were also able to program a graphical user interface on such limited hardware. I was wondering what you had to learn to build and program such a machine? Thank you.
I'm a high school freshman (soon to be sophomore) and I've been planning to do a similar sort of thing, albeit with a z180 instead of a micro controller. As of now, the computer is going to pair a 10mhz z180 processor with a 1mb SRAM chip and 256k EEPROM. For the video card, I'm going to cheat and use an ATmega328 instead of having to deal with designing (or modifying) an existing video card design. I was also originally going to write my own operating system, but I've since decided on porting CP/M instead. Anyways, thanks for the inspiration. This was a pretty cool video.
How did you put somekind on of LabVIEW on you Propintosh?? BTW very immpressive, but that fault with a code is hilarious X-D, I'm not into a programming, but I can't imagine myself doing so.Love your channel.
I'd say that sane variable and function names are far more important than comments. Comments can clutter the code if used to much. If the code isn't obvious, which it should be, a comment might be useful, but otherwise a short introduction at the beginning of a file or function is plenty.
First video I watched from your channel, autosubbed because of coolness. Did you get one of those pis eventually? You should, I'd like to see what you can come up with software wise.
Reminds me a lot of the stuff I used to wright for the TI-82 back in the 90s. I actually got a functional wireframe 3d engine working on a TI-82. Wasn't much you could do beside walk around the little wireframe house I hard coded in, but it gave me something to do in 9th grade pre-calc class.
In school I remember my java teacher always said if you give your variables/methods etc smart names then you'll never need to comment your code regarding what it does, only what it can interact with ('code coupling' === 'failed assignment'; , hence can). He was spot on too. I can still tell what my code from years ago does just from looking at it and I've been using a different language for the last five years. Point being.. for **c*$ sake tell me you don't still use actual variables to name your variables....
This reminds me...In either my sophomore or junior year of high school (most likely junior, but I couldn't access my schedule to confirm), I built a little game using 74xx series logic chips and a 556 timer chip. Basically, it was a two player "see who can hit the button first" game, complete with a scoring system. Of course, it did have a few glitches. Unfortunately, I tore it down shortly after the presentation. However, that led me to my next adventure: Messing around with the Arduino boards I have.
Can...can I go back to being a teenager so I can learn how to code without having to cut my leg off to do it? 15 year old now: Oh, I just threw this little thing together and wrote a bunch of custom code to make it all run, no big deal. 40 year-old me: Um...I can write documentation and set tech policy and build my own computer! I'll be replaced by automation in the next couple of years!...
This machine looks a lot like a micro of about 1980-82 (no PCs apart from IBM until about 85). If you built a machine now with the same computer power relative to today that you did then, what would your new machine be able to do? Would you be up to the power and versatility of something like an Amiga 500- or would the "new" machine basically be a Macintosh Classic? Which direction would you go in?
No comments and single letter variables! I can't tell you how many programs I wrote just like that. It's still fun to go back and look at stuff you did when you were a kid.
Bit of an intresting thing: I was browsing craigslist the other day when I found a macintosh classic M0420 but it was black. At first I thought I found some undocumented rare macintosh but no, I looked up the model number and It was just a macintosh that was painted black. The paint was done really nice too also It had come off in some areas. Wouldve got It but the thing was broken and it didn't have a keyboard and he wanted $70 for it. It looked kind of similar to this thing.
Man I wish I was cool enough to build a computer as a high school freshman. I'm a junior at the moment I haven't ever really finished a project as cool as this
I know this is probably kind of stupid but you could try to write another demo for the propintosh and see what you can do by improving over the previous versions! :D I know you will probably not do it though.
This is awesome. If you could upgrade it a bit to support something like MikeOS' floppys (is fully documented, BTW), witch is very similar to your OS in purpose and usability, I think you have something I'll buy for a hundred dollars, better than the Playstation classic mini scam.
Try to write pure functional code and just give the functions descriptive names. It's self documenting that way and easy to debug since you don't keep state.
Wouldn't it be hilarious if Clint from LGR still _somehow_ covered this before you ? XD

I really like this video. It has a nice quaint feel to it, maybe even cute (in a good way though).
You could try using another Propeller chip to drive TV graphics and the CPU could send commands to the second CPU (which I like to call PPU).
This is awesome. If you could upgrade it a bit to support something like MikeOS' floppys (is fully documented, BTW), witch is very similar to your OS in purpose and usability, I think you have something I'll buy for a hundred dollars, better than the Playstation classic mini scam.
You must share code and scheme! Maybe someone will build it to. I think there is way to make more RAM.
Try to write pure functional code and just give the functions descriptive names. It's self documenting that way and easy to debug since you don't keep state.
Also when will this thing get the obligatory Sim city port ?
You should figure out how to add more memory and make more complex programs!
2:25 whats the small chip on the left?
32k EEPROM. It stores the program the Propintosh will boot to when first turned on.
Thanks
You could still use a microcontroller as a computer using something like the NodeMCU.
I tried to write a BASIC interpreter in C. My head exploded.
How did you get the Code on the Microcontroller?
Remember kids. Always comment your code.
I wonder if it's possible to make a modern day Macintosh clone WICH can run actuall Mac software and has more features.
Like a Ethernet port USB etc.
And yet the most technological thing I have done was replace the Display of my phone using a "all included" kit I bought from amazon
now instead of just one 32k memory / processor you could put several ones interconected to see how much you can improve the project.
Something to cherish!
Except this would be perfect computer to develop your own OS
How much would you be willing to sell that for?
can you please share the details of circuit and code
Will there be a Propintosh emulator one day?
How much did it cost to make?
So cool that you made this in high school/early college.
Or if your language is high level enough, never comment your code and make sure everything is named in such a way that it explains itself.
Do you ever plan on selling these? It could be a cool retro item but not the best computer :/
