I'm already planning on doing the CD4050 for S-Video. It's the composite side I'm really worried about: what's the right way to mix Chroma and Luma to get a good composite signal? Oh, how I wish that the Commodore 1702 monitor had stereo audio. I just got one, finally, and it's wonderful, and has separate Chroma and Luma, but only one audio channel. So I'll need to add a mono/stereo switch to my 2600 mod as well.
