This is very impressive. How did you learn to design a real computer, not the toy ones a lot of people made? I read part 1 and part 2 and looks like you just “thrown in” Ethernet and other stuffs and it was done. Really hope to learn from the process, thanks!
This is really cool and impressive... but relatedly...
Has anyone figured out what the minimum specs for Quake are?
I feel like the first thing everyone does with a computer is to determine whether or not it can run quake, and I'm just wondering what the like, most simple computer that could exist is, that could run quake?
Quake 2 was the one with the clever approximate inverse square root code, right? I wonder (especially since there’s an instruction nowadays to draw inspiration from), can you implement it “in hardware,” so to speak?

I find first version https://github.com/petrmikheev/endeavour much more impressive. Dude somehow managed to get 100MHz DDR1 ram working on 2 layer board with no ground reference :o Its one of those things you only attempt when crazy or dont know any better. Anyone with EE experience will tell you its impossible, like flying commercial grade SoCs in satellites :) Mad lad.
I can't imagine why a 100 MHz digital signal at 2.5 V would be even particularly challenging on a small two-layer PCB. A lot of signal integrity lore has to do with passing EMI compliance (this almost certainly wouldn't), as well as with people extrapolating from Rick Hartley videos without pausing to think if it really applies to hobby stuff.
