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.
