[Coco] CM-8 Service Manual

The cord, the monitor is probably just sitting on it. Both come out the back.
As to Roy's box, already on the list: I think he had pity on me, so hurried a bit with mine :)
I bought all this neat, cool stuff from Mark: SuperIDE, Sardis FDC, repaired J&M FDC, and the CM-8 went out.
NitrOS-9 in 80 columns is not really legible out of the video-out connector, so I'm basically stuck.
Well, until I get Roy's VGA converter - then I should be good to go again except...
Anyone got an MPI for sale for NOT a King's Ransom? Mine is on it's last legs, and I'll need one to
test the floppies I got from Art so I can make .DSKs out of them.

Can't really help you on the issue, but I was curious about the cord
coming out of the -front- (bottom left corner) on the picture you posted...?
...and I must be getting old: I could've sworn my CoCo 3 always read
"SUPER EXTENDED COLOR BASIC 2.0" without the floppy drive connected (but
I don't mine set up right now to check); I just re-ran VCC and ejected
the MPI, and it comes up "EXTENDED COLOR BASIC 2.0", so that must be
right unless I'm going crazy, senile, or both...hmm.
I've heard/read here (you might check this list's archives) that there
did (at one time?) exist boards meant mainly for MAME emulation to
convert certain signals to VGA (which you want) and/or composite (which
you don't want); supposedly some were able to work with the CoCo 3's
output (???). I looked on Ebay ("mame converter") and found some, but I
don't know which, if any, would be possibly work. It might be something
to look into, at least.
I'd still put in for Roy's converter; I have one from one of the initial
runs, and I liked it's output - well worth waiting for.
