There is a video connector that comes off the Color Classic Analogue
connector (input from the logic board). It has 6 wires feeding into the
video hardware which I have decoded using the CCFAQ site as follows:

1 = ? ground (not defined)
2 = Red Video
3 = Green Video
4 = Blue Video
5 = Composite Video
6 = ground

Obviously I have not confirmed for sure what pin 1 connects to, though the
traces appear to be a common ground which would make sense for the RGB
signals.

I intend to take a VGA cable and send the appropriate signals out of another
computer VGA card and feed them into the corresponding CC video connector.
If I am correct, this will effectively make the CC an external VGA monitor.
If I'm lucky, the brightness pushbutton board on the front of the monitor
will continue to function normally. There are 15 pins on the VGA connector,
several of which will not be used here, such as V-synch and H-synch, but I
don't see a corresponding pin anywhere on the analogue connector from the
logic board, so I assume it is not needed. I also don't see a composite line
coming out of the VGA pins to route into pins 5 & 6, so I assume this is not
needed, just the RGB and common ground.

Anybody have any thoughts about this approach?
