My DIY FPGA board can run Quake II

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

Willing to solder BGA, but not willing to use 0402 components while using the stencil anyways?

Nonetheless, impressive project!

Section 6 where you link to Quake II is 404. (at the time of this post)

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.

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

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

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!

What's the deal with the diagonal squigglys

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?

Very impressive, and I'm sure satisfying. Kudos!

The diagonal traces and the empty spaces are throwing me for a loop. Is this the autorouter in action? (But… still, nice work.)

Good to see I'm not the only weirdo still using Midnight Commander.

Quake II had the best fn soundtrack.

Hey, routing your own length-matched traces, nice. Is this Altium?

Very impressive project!

With Claude, a software engineer can now be a hardware engineer.

Another board has become Frag complete. Important milestone!
