I can't speak for Andrew, but for me, I already have this SBC with
CPU, some RAM, enough ROM, and a peripheral bus with 5 or 6 PIO
chips, all in a package a little smaller than an Apple II PSU.
You might ask on comp.os.cpm; at least one person there claims to have
installed CP/M on a printer buffer/sharer.
