Are you on the CoCo mailing list? Have you seen the RGB2VGA by Luis Antoniosi (CoCoDemus)? I know at one point he had been tinkering with making it support composite from the Apple II. It’s semi open-source, I think there are 2 versions and the latest version is currently all closed source. https://sites.google.com/site/tandycocoloco/rgb2vga -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com
