In response to those wondering if CP/M emulation is available on the
8088, 8086, etc.-- there is a fine emulator program available on many
bulletin board systems areound the country. It is called Z80MU and it
emulates a CP/M machine running CP/M 2.2. I have briefly played with it
(it will run the original crowther's adventure) and it seems to run
well behaved CP/M software.

This program was reviewed in the Oct 86 Byte on page 203. I would
recommend that you folks take a read on this article. The major
difficulty that I found with this program is getting the CP/M stuff
onto a DOS diskette. The article explains a couple of methods of
doing this, but I wound up using the serial port transfer (works
every time).

I have run this program on numerous configurations including the PC/XT,
AT, and clones with the same results. The faster the clock speed of your
machine, the faster emulation of the Z80. On an AT, the program clocks in
as about an 8mHz Z80. (Better than that old Altos you are using huh??)
The Z80 speed is determined by some internal algorithm (my machine runs
a tad fast).
