[Coco] The thrill of CoCo'ing again.

[Christopher Barnett Fox]

I really couldn¹t say, Kandur. I found the AVC-011 from a post where
someone else had also used it for CoCo3 RGB to VGA. I didn¹t do research
on alternatives, since I didn¹t know enough about the technical details
and requirements. I needed a solution that would be as quick and easy as
possible. With the AVC-011, it only requires the construction of a cable
going from the CoCo¹s 2x5 pin header RGB out to the six-pin CGA input on
the converter. It¹s a direct connection between the RGB, H and V sync and
ground pins on both.

My goal was just to get something clear enough for 80-column text. I
haven¹t finalized the cable build, and I know my signal quality should
improve as I reduce the signal path, etc., but even a rough and quick
setup produced very usable output.
