Could the HT12 be replaced by some "pie", or other project?
They aren't mainstream to find... just curious.

Might be tough to emulate a 20 Mhz memory interface and ISA bus with a Pie.

But if you are going ATX, I guess you could include a Picogus to fill out the Sound and USB ports on the standard ATX IO shield. How cool would that be? 286 with a USB port that can do CD emulation?
