Project DoomBox

I had several spare parts from my previous PC projects in my possession and wanted to do something with it. So I decided to do my first PC case-mod with retro parts. The finished PC should be able to run DOS games like DOOM 1/2, Duke Nukem 3D and others.

These are the spare components I used:

To make the PC complete I ordered several parts from Amazon:

This is what I came up with:

The chest has several holes in the bottom as air inlets. The fan of the power supply blows out the hot air on the back.

I used the RJ45 coupling to get ethernet to the backside and soldered the PS/2 adapters for keyboard and mouse myself.

The display and the speakers get their power from the ATX supply so everything turns on when you hit that power switch… 

On the software side I used FreeDOS as an operating system and made myself a game launcher menu using DJGPP and the GRX library. I was even able to find code to play samples with the SoundBlaster. A short video of the box booting into the menu and running doom is available here.

This was actually the second try on the launcher menu. I already implemented a version using FreeBASIC which worked fine on all my PCs and in DOSBox but failed to switch into graphics mode on the DoomBox. I tried to change the graphics board, but with no effect. Seems to be an issue with the mainboard itself as swapping out all the other components didn’t work either…
