Got an interesting mail from a fellow who has a
"PMC MicroMate" CP/M
computer, and was wondering about it. The specs are neat - it's a fast Z80
(4MHz), but has 128k of RAM (so I guess it's CP/M-Plus, or a heavily
modified version of 2.2), an internal 400k floppy and some sort of interface
for three external drives. Am asking for details on the external drive
interface. The machine doesn't sound familiar to me, but it sounds like a
neat little thing - it's just a boxen, you need a TTY.
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.

PMC made a crappy TRS-80 Model I clone called, I
think, the PMC-80, but this
is obviously a different machine. I'll see if I can come up with anything on
it.
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.
