[Coco] Using Roy's vga adapter with other computers

[Bob Devries]

Hi Aaron,

http://medialab.freaknet.org/doc/Hardware/Retrocomputing/commodore-128/C128-pinouts.txt

According to that website, the RGB is indeed digital:

pins 1 & 2 are GND,
pins 3, 4 & 5 are RED, GREEN and BLUE
pin 6 is INTENSITY
pin 7 is MONOCHROME VIDEO
pin 8 is H-SYNC
pin 9 is V-SYNC
