not to go off topic, but I think part of that solution would be to tap into the motherboard before all the signals come together and have an SVIDEO type output
I'm not sure that will do the trick. I don't claim to be a video expert, but from what I gather the timing of an Apple II is "off" a bit from the NTSC standard, resulting in odd behavior from scan converters. Color graphics also depend heavily on aliasing, which does not seem to be handled at all by any of the converters I've seen.
I wish someone with a lot more domain knowledge than I would produce a scan converter that uses a sliding window to produce pure colors from a source that normally relies on CRT monitors blending things. None of my older 8-bit machines look all that great on LCD monitors and it's surprising that no one has tackled this issue head on. There would appear to be enough owners of Atari, Apple, Tandy Cocos, etc. to make this a reasonably sized market.
