[Coco] Re: [Color Computer] CoCo 2 and a PC VGA

Fri Sep 10 15:16:28 EDT 2004

I've been using a TV and/or composite video capture card and an old pc to do the 
conversion.  It's cheap if you have the old PC around...

(all my cocos are modded to composite now, so I just do a composite capture card...but a 
TV tuner capture card should work too)
