My friend's dad built one for him, for DOS/windows though. Must have been around -89 when we were 12. I think Scream Tracker had the schematic bundled with it as an ASCII drawing. We were taught how to solder in primary school, but I remember the schematics being way too advanced for us. Looking at it now it's just a simple resistor ladder tree I think it was roughly the same as Covox, someone had written a sound blaster emulator for it, and it worked pretty well on games, scream tracker/fast tracker and demoscene demos - for the price of a parallel port connector and a few resistors, pretty cool.
