I was wondering, does anyone have programming information for the FM Towns/Marty I/II? I guess I could look at the source for one of the emulators, but there don't seem to be any docs, at least on the English web.
And I'm sure I've seen some detailed docs for the PC/FX, but I can't seem to find them again. I think there were detailed register layouts, bios calls, memory map, etc. (Update: found: http://daifukkat.su/pcfx/ )
