Oops, I looked it up in our Seiko CH5301 hardcopier manual and it says that
it is compatible with both RS-170 and RS-343 RGB composite video as well
as R+G+B+Sync composite sync.  Our Ramtek GM-850 monitors say they use
"EIA Std RS-343A (separate composite sync availible)" which is 1280 X 1024
X 256 color resolution in our case.

We just rolled in a couple of Ardent workstations that provide 1280 X 1024
X 16,777,216 color resolution.  The manual only says RGB with sync on green
60Hz noninterlaced, no RS numbers are shown but It appears to be RS-343.
Does anybody spec the actual color resolution of their monitors?  From my
experience, it varies considerably with the age of the CRT.

Perhaps some well informed individual could post a table of common video
formats and their associated scan frequencies, resolutions, interlace
characteristics, etc.
