[Coco] New s-video board for the CoCo3 RGB port

[Zippster]

Hello everybody,

I’ve put together a composite and s-video adapter for the CoCo3 RGB port.
I had a chance to put together some prototype PCBs I received back, and it’s looking
pretty good.

The s-video output in particular is excellent.  Very useable 80 column text screen and
nice graphics screens for games.  Here is a link to some pics of the board and some
screen shots.  The screen shots are all s-video on a 50 or so inch LCD TV.
