You don't NEED 64K. CP/M can run in 16K. But, if you want a decent sized
TPA, you can have 50+ K TPA with 64K, or even 63K TPA with 128K.
8080. Yeah, a Z80 is NICE. and FAST! and some aps insist on it. But,
CP/M can run on 8080, 8085, and anything else, including emulators that
can handle 8080 code.
It's too bad that nobody brought up CP/M on the Kyoceras (Radio Shack
model 100, Nec 8200, etc). THAT would have been a project.
Or on the Epson RC20!
