DMC Commfile

Ok, my friend gave me two DMC systems this weekend. Never heard of DMC
and I'm hoping someone else has.

The box is about 12" high, 19" wide and about 18" deep. The front panel
has a POWER and RESET switch. It says "DMC" and under that "Division of
Cetec Corporation". It also says "COMMFILE". I'm assuming that's the
name of this system. On the back serial number sticker, one says model
125 and the other model 130. The difference seems to be in the number of
serial ports and RAM each has. Both have two integrated 8" disk drives.

Inside we find a card cage with 8 slots. The cards at first look like
S-100 but upon closer inspection (and a count) I noticed that they
actually have 60 conductors on the each side of the edge connector. On
the component side, conductors 12-51 are common. The cards are about 1.5
times the height of a typical S-100 board, and the same width. The CPU
board has an 8080 on it.

There are two serial ports on the back of each, one labeled "OPERATOR
CONSOLE" and the other "MODEM".

I got two 8" floppies (hacked into double-sided) with the system. Only
one seems to boot. I plugged a terminal into the operator console port
and booted the disk (it only takes about 2 seconds) and get:

READY (V7.0)

and then a flashing cursor. Haven't figured out any commands yet,
because anytime I type anything I get:

?? INVALID COMMAND

and then the READY prompt.

Anyone know what I've got? I don't know if my friend knows but he wasn't
around when I picked them up so I haven't had a chance to ask him. My
guess is he knows nothing about them anyway. He's been sitting on them
for years and finally decided he was sick of them taking up space in his
room.

Any help would be appreciated.
