[Coco] RGB video on CoCo3

[Phill Harvey-Smith]

Ok, so I've pulled my CoCo3 out of storage because I need to test 
something on it, and am really quite disapointed with the quality of the 
  composite video display on my LCD TV. Though the TV is fine with other 
machine's composite (Dragon included, but then that like the CoCo 1/2 
uses a 6847 instead of the Gime).

So I know the CoCo3 has an RGB port on the underside of the board, that 
I can hopefully use to drive the TV/monitor, which as well as composite 
and ariel input also has SCART and PCVGA inputs, both of which I know 
work fine and display a nice crisp picture with a variety of retro systems.

So how can I go about utilizing this port, if it's going to be a problem 
the CoCo3 is of a US NTSC model, and though the TV is a UK PAL model, it 
is also capable of displaying an NTSC picture fine (tested with a Tano 
Dragon, and an MC-10).

Cheers.

Phill.
