64K, surely?
What Microprocessors are still being sold new? 6502?
Z80?
Not many. You may find that only the high-volume distributors have
any of the 6502, Z80 or 6809 generation -- and you'd have to buy
in *huge* numbers. But having said that, many CPUs are simply not
made any more. So, you'd have to go to a specialist in obsolete
semiconductors.
It would consist of a small board with RAM, ROM, CPU,
and a serial port.
I was thinking of 6809, 27256, 62256 and 6551. Maybe 6522, maybe
AY-3-8910.
Is anyone interested?
Oh, yes!
