Dear Roy Justus,
Congratulations on your successful conversion of two CGA monitors to CoCo
III - compatible analog RGB! I did two or three such conversions back in
the mid 1980's, myself. All worked well, and at least one I accomplished
without a factory schematic diagram, doing just as you did, just tracing the
video circuitry. Your report brings back to me happy memories!
The only "problem" with this approach (apart from a mild amount of
tediousness) is that CGA monitors, themselves, are getting as rare as hen's
teeth now, nearly 4 years into the 21st century!
