I designed and built a number of GPUs out of TTL in the 70s, although we called then VDUs back then. It's interesting to see your approach... I can see you're a software guy! One of the engineering challenges back in the mid 70s was to use the minimum number of chips. Also back then we didn't have any chips beyond 7419x. The cheapest counters were the 7490 and 7493. Also RAM was expensive. The designs typical of the day used 256 visible pixels across and 256 visible pixels down, 320 by 320 including front & back porches plus vertical blanking period. Using a 5MHz clock, this gave the 15625Hz Hsync frequency. The Vsync works out at about 48.8Hz, good enough. Divide by 320 is achieved with 7493 binary counters configured as div-by-32, plus a 7490 div-by-10. When the MSB goes high, that's the blanking periods. Sync timing is achieved with 74123 monostables: digital comparators massively increases chip count. Instead of a complete memory mapped display (remember RAM was expensive), we used character generator ROMs. These presented 8 pixels at a time, which went into a shift register either a 74165 or 74166 from memory. At 5MHz, the character time of 8 pixels is 8/5MHz = 1.6us, which was easily achievable with the ~450ns RAM and ROM we had back then. For the CPU to access the RAM, we need to multiplex the CPU's address bus with the 749x counters. This was done with 74157s. When the CPU needed to access the RAM, it took precedence over the counters, so you'd get snow on the screen during CPU accesses. Including the RAM (8 x 2102) and character generator, maybe 30 chips in total. I was a 12yo school kid at the time when I designed my first one, no oscilloscope, just an analog multimeter and an LED for debugging.

I tried to build something similar that used the VGA standard. I only got as far as the timing signal generation and pixel counters, because although it all worked, if I even breathed on it, it would stop working for some reason or another. I think the counters I used didn't like the extra capacitance in the breadboards. It was a great feeling measuring all the timings with my scope and seeing it match perfectly with the VGA standard. If I was going to continue I would have needed to build it all on proto board with magnet wire like my z80 computer. I never bothered making a schematic diagram though so it wasn't worth continuing. You did fantastic for never doing any electronics before

Wow. This is soo impresive!!!! People are awesome!!!!

It had like 1 fps with the smallest possible image data in my standard. This is a really cool project though, and it is super interesting to see someone build it irl. I can recommend scrap mechanic to you, obviously, it is more satisfying to see a result in real life than in a game, but I think you could have a lot of fun building stuff in it, and it might even be a good place to simulate your circuits before you spend money on your stuff in real life. It doesn't have stuff like memory ICEs, but you could simply make them with regular logic, and copy-paste them however many times you want.

clock latch the output of the EPROM. So your actually addressing the eprom and fetching the next bit, while displaying the latched previous bit, that gives the EPROM the most time to settle, the latch "will" hold that settled output for full clock time. You may need to tweak when the clock happens to get a perfect output, but once found...

Sweet lord - I hope those jumpers don't randomly snap! Several people have done VGA and similar with full-fidelity emulation of NES and even the BBC micro on the Pi Pico board with just a "few" external components.

My colleague was assigned to built tele text device to mix running text onto bottom of TV screen, as a compulsory project to complete his undergrad. electric engineering degree. It was 30 yrs ago. And he ended up being retired without graduated because it's far beyond his capacity as an undergrad student then.

Latches, my man! SN74LS573 or similar. You can use a very brief signal to latch the output from your ROM chip, thus allowing the ROM's output to stabilize before sending the next byte out. It will mean reorganizing your data on the ROM chip by about 1 byte, but that should help.

This is hilarious to me, as I went down a very similar road (and same glitches and pain) 7 or 8 years back. I didn't try PAL, but NTSC... but with 'golden arches' of wrirwe mess causing interference (stray capacitance etc), it was making me nuts. I ended up switchign to VGA output, as much more widely available on monitors, and also a _really easy_ signal to generate, in black and white or colour. (Same analog range style to generate a colour or b/w). A couple years back I went FPGA to try and figure out HDMI and got that going too .. and its a lot like VGA but with some evil suppressed-information encoding at the end. Go VGA, and use Eagle or whatevere to get some PCBs printed .. doing it all in jumper wires is fun to a point, then just annoying ;) (When elecrow or jclpcb etc can give you a dozen 4" square pcbs for $10 a week or two after you place the order, its pretty nuts.)

You appear to have missed the several weeks required to become proficient in an HDL and the FPGA's tool chain. More seriously, you can do all of this on $2 microcontrollers using on chip DMA and on chip timers, there's no need for FPGAs. But I found the approach to do it solely in software first was interesting if a little quaint/naive!

First Live stream jdh* "You unemployed or sth?"

Great job! You can use an FPGA, like I did in college for computer engineering. They are not always so expensive-- the one I was using is discontinued now but it was only $5 - $6 US. Some soldering required! But then just download the logic gates (if you've never used one before). 5 minutes from working simulation to working circuit! Keep up the great work. Also, you're very attractive! Congrats!

I am glad that there are some people in this world that think in similar way to me! I hope there will be more like us 😊 I got soo annoyed when I found out how big companies manipulate people to sell more that I just had to start to build things myself really !

Good luck trying to put an RTX4080 together in your bedroom. There's a reason there's only a few factories in the world that make the wafers for GPUs.

Great work, I made the Ben Eater video card not too long ago myself. Have you read the TV Tennis schematics from Popular Electronics? It produces a sync signal with a pair of 555's and a pair of NANDs in monochrome.

That sounds fucking awesome. 555's are the fuckin best

Nice. Please make that into a font, also I'd love to see something like this based in software that could be played with.

you genius bastard! amazing mate!

I love that you do this. Great content, smarty pants man.

I'm still waiting for the video where you mine silicone to produce homemade microchips.

THANK YOU SOOO MUCH JDH I HAVE BEEN WAITING FOR THIS FOR SOOOO LONG.

This video caused massive blood pressure spiking when I saw that circuit

Color was indeed 'hacked' into it. The two chroma channels were modulated together using a carrier frequency and then basically just added to the luminance channel. Pretty much like analog tv.
