That's some mad dedication to go from kicad schematics to running Quake. Very impressive!

Cool write up, getting initial bill shock from 2 layer to the 4+ layer PCBs is a rite of passage :)

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!

Quake II had the best fn soundtrack.

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?

Cool! Have you considered offering this board on Crowd Supply or similar? There don't seem to be many boards available for Efinix FPGAs.
