There's a ?M-3 locally I've been meaning to pick up to round out my 1000HX. It's a much smaller monitor than the CM-5. At first I thought it was a monochrome monitor (which would imply VM-3), but the CRT has an aperture grille which leads me to believe it's a color monitor instead. Anyone know what the specs of this one are?
There is indeed a VM-3 monitor; it appears to be an older version of the VM-5. See here:
Google turned up nothing, even with leet syntax searches.. I did find references to a CM-4 model though.
The CM-4 is just an older version of the CM-5 (would have been contemporary to the original T1000).
