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.
