[Coco] CoCo 2 Factory Composite Video RE'd

[Bruce W. Calkins]

Be advised that the modulators are different in the CoCo 1.  For one thing 
the MC-1372 is on the motherboard and not in the RF modulator.  My CoCo 1 
composite monitor driver simply clipped to several points on the 
motherboard.  FWIW; it looks to me that you have complicated a simple task. 
"Back in the day" even the CoCo 2 composite monitor drivers simply clipped 
in, the rub being that the RF modulator needed to be opened to access the 
MC-1372.
