All of my listed systems work especially the CP/M
hardware.
Not me--I do it under emulation on a nice speedy windoze system.
It's amazing how fast MAC will munch code running on a software
emulator.
Qualifies as an 8080! With a bunch of Pc hardware to
impair it. ;)
Maybe, but ti couldn't run JRT Pascal. AFAIK, the only commercial
product that ever used the bizarre coding sequence:
LXI SP, PROC-1
CALL PROC
i.e., the stack is stored just prior to the entry point.
This throws the V20 into never-never land. I've got the technical
bulletin from NEC that talks about this. There was no fix, AFAIK.
