Subject: Re: CPM emulators written in 68000 assembly language

Just some comments. 1) Most of the tools you mentioned like
M80, L80, MAC, RMAC run on an 8080 machine and don't require
a Z80 (emulator).   2) If you have an old PC around, you can
get quite respectable performance with either emulators like
Z80MU or 22NICE.  3) Most unix 68000's use a peculiar brand of
68k assembly language mnemonics compared to Motorola standards.
For example, SIMCPM is written using Motorola mnemonics plus
quite a few macros.   
    Anyway, I would suggest getting the 8080emulator available
from hopf.math.purdue.edu (128.210.3.18) in the ~ftp/pub/cpm
directory, and trying it out to see if you really need higer
performance ( compared to the work of getting it).

I didn't write the emulator. I imported it from the U. Tokyo
archives, and the documentation is in Japanese. I figured the
configuration out from the source files. Someone in Australia
promised me a rough translation of the docs, but I don't have
them yet.
