If it's brown/tan, it's metal, the plastic case is white, you would
know right away. The plastic case was made pretty close to the end
of the line for OSI. Not actually distributed until after they were
bought by MA/COM. The plastic case was an effort to compete with
the Apple II. A plastic case C1P should have a later rev 600 board
in it. Some of the later revs included built in 32 column support,
color support and software adjustment of the serial signal rate (for
the rs-232 and tape interfaces).

Blue/black was the earlier color scheme for OSI so, in a blue/black
machine, you would expect to find earlier board revs. The C2-4P
was the only machine that stayed blue/black for its entire life
(as far as I know anyway... I never seen or heard anyone mention a
tan/brown C2-4P).

I'd really like to see (or at least get a more detailed description of)
this dual 5 1/4" cabinet. If it has an OSI tag on it, what it says,
what color is it, etc.

I have a late rev 600 board schematic on line at:
http://members.bellatlantic.net/~vze25qnw/
Interestingly, the page no longer shows up on a google search.
It's my intention, when I get some free time (like maybe when my kids
go off to college and I retire), to put up an elaborate OSI museum
online.

It could really be just about anything! C1Ps are almost always hacked.
I don't quite understand your description of where it comes out. If it
is a wide cable, around 30 pins (memory fails at the moment and I can't
go digging for the docs right now, I would wake up the kids and get in
trouble) and it comes out of the back of the unit, then it's probably a
floppy cable to go to the 5 1/4" drives. If it is 12 or so pins and
comes out next to the keyboard, then it might well be a cable to go to
the optional num pad that OSI made.
