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.

Thanks a lot! I'll check.

I have the C1P model which came with some interesting sale documentation and
even some program printouts by someone who was actually using it. it also
have what appears to be a tech. reference manual and board schematics. i dont
have a scanner, but I suppose I could use the copier at work if theres a need
for this material.

I don't have much, but I can give some of what I know. Ohio Scientific
made, or so I gather, four 8 bit home computers - the C1P, C2P, C4P and
C8P. Most of my info seems to be on the C8P, which was regarded as The Home
Computer of the Future largely due to its ability to control your security
system, electrical appliances (like lights), smoke alarms and so on, as
well as being able to dial up the police when needed.
The C2P, according to the little I have here, was a CIP with more ports, as
the IP had but one. Thus the info I have on specs is mostly for the 1P, not
the 2P, so I will give that in case it helps.
Anyway, the IP is said to have been the first fully packaged home computer
that you could just plug in and use. It came with either the MOS 6502 or
Motorola 6800 cpu as standard (depending on your requirements) and had a
CPU expansion board, allowing the addition of a Z80 or one of several other
popular CPU's. It had a standard 53 key keyboard, upper and lower case
letters, and 64 char by 24 line mono video. 4k or 12K RAM was standard,
with8k BASIC in ROM.
Sorry that I don't have more, but my interest tends to lie in the history,
rather than the specs. Just for fun, it is worth noting that Ohio
Scientific is noted for being the first PC Company to have a woman (Charity
Engel Cheiky, I think) as President.
Adam.
I recently aquired a 1040STe and STf as well. It's a great machine, If you
need a monitor for one I know where you can get a color 14inch stereo
monitor for 85.00. This machine will do Slip, PPP and do just about
anything a PC will do on the web, {with some upgrades} the Atari ST's were
very cool machines I've found. If you need any info or help with the Atari,
don't hesitate to ask, Its a wonderful fun machine.

Picked up few new finds this week. 1. A Challenger 2P (Model C2-4P) by Ohio
Scientific SN5040. Anyone have spec's on this one?; 2. ATARI 1040STF with
mouse; 3. A IBM 5110, had to leave the 8inch drive unit and the printer no
more in car; 4. Tandy FD 501 unit; 5. IBM tape unit Type 3363; 6. SUN SPARC
station 1 model147; 7. CPT9000; and 8. Nextstation and color monitor. Now to
get it all cleaned up and working.

Correct me if I am wrong, but wasn't the ZX81 a UK machine? I was under
the understanding that it was sold in North America as the TS1000
(Timex/Sinclair). I'm pretty sure the ZX81 was made in the UK (at least
that's what mine says on the case).
Of course I'm not sure if it was made in the UK for a North American market...

The ZX81 was sold in both the US and the UK, the US version had a VHF RF
modulator and the UK version had a UHF modulator.

CLASSICCMP READERS: Please pardon the CC. I'm still not sure that Tim is
able to receive mail from me for whatever reason.
Ok... here's the current status. I've used SYSGEN as you described, reset
a couple of cards as needed to correct some mis-set addresses, and put
everything back together.
I've used AUTOCONFIG ALL /SELECT=(PU,PT,XQ,TX). This should have
configured the tapes, the disks, the DELQA, and the DHV11.
I then issued the commands:
SYSGEN> WRITE ACTIVE
SYSGEN> WRITE CURRENT
SYSGEN> EXIT
I then shut down and rebooted. However, the second TK50 still does not
appear to be available under any of the device names. It should, I thought,
come up as MUB0:, PUA0: or PUB0:. I cannot mount it under any of those
designators. At this point, I am reinstalling OpenVMS 6.2 from scratch on
another drive. I'll see what happens then.
I've borrowed some documentation that covers SYSGEN, but either I'm not
doing something right or I've overlooked something so basic that either one
of us might take it for granted.
Could the problems I've been having with the license management affect it?
As soon as I get the hardware issues dealt with, I can -- FINALLY!! --
copy that stupid tape!
Please let me know if you receive this in your E-mail box or only from
CLASSICCMP. Thanks in advance.
