Since emulating a CPU is a fairly memory intensive thing to do,
it's unlikely that the Z-80 emulator code will require any reworking
to fit your needs. There is an option you need to set, though. Two
files are included to handle I/O instructions. io_mem.c implements
a 256 byte RAM on the I/O space. io_ask.c prompts the console
for input and prints output writes.
You also have a couple choices for main():
debug.c is a debugger. This debugger is intended primarily to debug
the interpreter itself rather than debug z-80 code.
upm.c implements CP/M on top of the emulator. See README.upm
Many thanks to Mark W. Eichin for his help in debugging some
of my truely nasty code during Alpha-testing. Truely a saint.
