Wouldn't it be hilarious if Clint from LGR still _somehow_ covered this before you ? XD
Clint's basically covered everything
*he already has*
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...
@@gavinthecrafterLGR: "This was graciously donated to me by-"
The Science Elf:"HOW DID YOU GET INTO MY HOUSE??"
LGR:"uh oh"
Smart enough to build a custom computer when they're 15.....
Not smart enough to give variables normal names.
*you were so close to greatness*
I've repented, I promise! Sometimes now, I leave more comments than code. :)
More comments than code? Careful there, too many comments can render it almost as unreadable as no comments!
Self taught programmers learn the hard way, but once learned they never forget.
The Science Elf Linux has properly commented code....

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.
You made that when you were 15? Holy shit
Oh cool, I have one of those. It's a fun computer.
Right. Sure.
This should be the top comment.
You obviously missed the joke.
Can it run roblox?

Oh, and in case you were wondering, yes. I'm still a potato.
Well it is a potato pc so, i guess, its fitting
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
_Freshman year of high school?!_ Man, you must have learned early, I'm still trying to figure out what I'm good at and I'm in college.
Grilled Cheese Sandwich - this video confirmed my suspicions that the science elf is Very smart.
it's an elf you're talking about, c'mon
an elf that has science in the name
bwgti surely true, but if he had computer engineering classes available in school, likely privileged as well
what does that have to do with his intelligence?
Moral of the story: Comment your freaking code
MarkusTegelane here's my code: code123
my rarest computer is my virtual box
nice, did you make it yourself or just use virtualbox?
.
[one letter can change the meaning]
nodrinks stop being gay
nodrinks There wasnt any incorrect grammar in there?
Virtualbox is one word, sentences start with capital letters and end in periods, and you're never gonna get off the ground with a gaming channel.
And so are you for supporting OP :)
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 used to never comment my code, but now I find I can't think straight without doing it.
Same lol
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...
You're the eXtern guy!
Propintosh 2 release date ???
"When i get to it, probably never"
This would be dope! Also I was thinking that he could use a Raspberry pi.
I finshed a second one its not simliar thought
@@KekseTheFox how so?
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.
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.
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 ;)
If you still have it, can you review it on your UA-cam channel? That is so cool
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'm surprised this comment didn't get more upvotes. Maybe it would on a more DIY-computer type channel.
if you search propintosh in 2019 you will see roblox profiles
*_"AT LEAST IT HAS HEADPHONE JACK"_*
I would love to see a video on how to make something like this. It's admittedly not very useful as a computer, but it's an amazing learning tool.
"Another fine addition to my collection!" -General Grievous
But can it create a GUI interface in visual basic to track an IP address?
it could, if it had visual basic and an interface to track the ip from
You're missing the joke...
Nino Ivanov UA-cam commenters do no understand what jokes are
but why didn't you add a speaker?
or a color display?
_just asking_
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 understand now
But wow 32Kb
Pretty nice project tho
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.
Not enough ram.
A color display will use up a lot of ram, he only had 32kb of it
I don't care how long your videos take to come out. The wait is always worth it. Good job 😁
I like the little treasures of the past!
Thanks! =D
Have you heard of TempleOS? You should do a video on it... And find out if it's usable lol it has an interesting back story too
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!
How about using several propellers (think multi-core/multiprocessor architecture) in the Propintosh 2 (if you decide to make one)?
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
How did you capture the screen? It looks awesome!
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.
Cool but does it run....
Donkey kong
yes
yes it does
"donkey kong: the new text adventure"
No but it could run Microsoft Adventure

>During my first year of high school
Thanks that’s the type of existential crisis I needed this morning
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.
I used to think I was smart to do a Pi lego laptop when I was 14. Now I see it was obsolete.
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.
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.
That’s awesome! Think you could share some resources on how to build one? Also, you should totally put that code up on GitHub!
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.
i know next to nothing about computers but i love new content from you :3
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.
Definitely didn't mind the clickbait, this is much better than what the title implies. Pretty inspiring, actually!
Wow you have a pretty good taste and quality computers, my friend. You did a nice job on creating that custom computer.
This is wonderful, thank you for sharing.
Do you make firmware or os for with macnihe?
Can you make a video series of you building the Propintosh 2.0 please?
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.
This is a neat project. Great job!
god damn you certainty know your stuff good video!
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 you teach us on how to make computers like the propintosh?
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?
happy green drink day
I Cant Think Of A Name *squeezes a body part with thumb and index fingers to inflict pain*
Does anyone know how I can get started on something like this? I'd love to build my own tiny computer at some point
honestly really impressive. reminds me of how in freshman year of high school I made a computer in minecraft.
You should continue work on this.
Itd be fun to see you build one that is far more powerful and and even possibly a useable graphical os that runs like windows 1 or 2
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.
i love the parallax propeller chip. i have been using it for about 2 weeks or so now.
That's actually really cool! Like, how could you make this when you were only 15? I love your videos, by the way. Keep it up! :D
PLEASE MAKE A MARK II. This was very interesting to see, and it would be soo cool to see a faster model!
Ladies and gentlemen,
the New Steve Jobs
*Wozniak
oof
lol
are the software and the designes available so that i can take over the development?
ohh so cool good job!btw can you do a video about updating This little machine?
What LCD screen did you use?
That's some real hacking right there. Forcing to work on something it was never designed to do.
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.
Oh Dang it I fell for clickbait but tell me, will you make a more "updated" version in the future?
Probably not, but I might show a few other projects I did with the Propeller in the future...
it'd be nice to have an actual mostly-full-featured custom computer...oh well, all is good enough
I really like this video. It has a nice quaint feel to it, maybe even cute (in a good way though).
Hello! love all ur videos!!
Would you ever release this code and make it open sourced?
The Science Elf: "Always, always, always comment your code!"
Me: *No*
I'd have used one propeller for display and stuff, and another to compute stuff
I'd guess the graphics one could _probably_ also handle the I/O, meaning you'd have the "whole 32kb" of ram purely for programs...
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
man i remember seeing one of those at a yard sale.....dang.
Also when will this thing get the obligatory Sim city port ?
Something to cherish!
You could still use a microcontroller as a computer using something like the NodeMCU.
It's all about the journey, not the destination. Great video :-)
As a freshman myself now. Your video inspired me to make something of my own
You're good at hardware and software, that's amazing. You only need two apps: your own Tetris clone and a text adventure.
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).
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
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.
Cool video, how many years ago was this?
I almost forgot to watch this today
Cool! My Grandpa did this sort of thing when he was in High School. Kinda feel like I missed the boat on this stuff :(
very nice! PLEASE KEEP UPLOADING MORE VIDEOS!
I wish I could do the stuff that you did, and I think I can do it, but, it's just that I don't know where and what to start with.
Can you do a tutorial to show how did you made it?
Ábel Lowescher hahaha nice one
what the
Magyar vagy
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.
What LCD are you using in this build? Or where can I find one similar to it?
So cool that you made this in high school/early college.
What is that big blue box on the
Computer board?
Do you ever plan on selling these? It could be a cool retro item but not the best computer :/
now instead of just one 32k memory / processor you could put several ones interconected to see how much you can improve the project.
What is this mystical "Smart LCD"? is it just an SPI display?
This man build his own computer from almost scratch! You just went from a level 1 computer geek, to a level 3 computer geek in my opinion!
Imagine if he made this computer a big deal and kept on improving it, what company would have come into existence....
How did you get the Code on the Microcontroller?
you could use a arduino for grafics so that it doesn't too much processing power
HE DESIGNED THIS THING IN HIS FRESHMEN YEAR OF HIGH SCHOOL? IN MY FRESHMAN YEAR I DIDN'T EVEN KNOW HOW A CIRCUIT BOARD WORKED
You could host a website and release the source code. It would be awesome!
Also, you could make it simpler, by making it a full BASIC computer or something like that.
not really
even on commercial computers of the BASIC era the BASIC mode was too slow for most graphics stuff like games...
Woah, you did that when you were 15!?! That's inspiring (I'm 15 now and couldn't do anything near that)!
