[Coco] CM-8 Monitor Specs

[Brian Hostetler]

Hi guys and gals,

            I just got my old coco setup going and realized one of my coco2s
has a composite video output with mono audio from a 1/8" stereo jack.  Most
of the coco2s have an RF RCA output and I was curious if the setup I have is
stock from Tandy, or was modified by someone.  In addition, the switch that
normally selects channel 3 or 4, sets the composite output to
color/monochrome.

            Another question I have is: does anyone have the specs to the
CM-8 monitor.  I have two of these monitors (for coco3 use), and was
thinking of using them for the coco2 also.  I could use a composite to VGA
scan converter, but I'm unsure if the CM-8 can handle 480 lines of video
(@60Hz).  If I recall correctly, the sync signals on the CM-8 are inverted
also.  Another approach could be to convert the Y,B-Y, and R-Y signals
coming from the MC6847 into RGB with op-amps and generate the sync signals
somehow.  Sorry if this has already been covered, I was off of the list for
a couple years when my email account was deleted.  If I figure out a way to
do this, I suppose artifacted colors would be possible with the coco 3 on a
CM-8   (maybe)..   Thanks.
