I just moved and things are difficult to find,
but I did find my MicroMate, just couldn't find
the user manual. The external disk interface is
(I assume) pretty standard, consists of a PC
board edge with 34 plated fingers (17 on each
side) spaced .1" on center.
The MicroMate system disk has a cool utility
that allows you to configure any of the external
drives as one of about a half dozen different
CP/M disk formats. The details escape me until I
find that user manual.

Actually, Personal Micro Computers had just
the opposite problem. They started with the
PMC-80 that included a built-in cassette drive.
Then they came out with the PMC-81. As I
understand it, these were sold around the world
with names like Color Genie, TRZ-80, etc.
Then Tandy sued them. In what was the first
case of firmware infringement, Tandy said that
the keyboard input routine was a little too
close to the original (or words to that effect).

That is when they came out with the PMC-101
"MicroMate".
I have all three machines.
