I'm considering a Homebrew project that if successful may be worth making in quantity.

Basically I'm looking for a chip that I can still find over 50 of easily, requires a minimum of external parts to function, and can take composite video in and convert it to RGB or RGB-Y ( having a sync output would be a plus) and not require other stages of a TV be present to support it.

I don't work on enough SS sets to know how to go about finding such a part.

Well for now I'm probably going to make the chroma decoder and sync sections out of disembodied 9-86 and 9-87 Zenith modules taken from a good spare upright CCII chassis then build up the additional circuits I want and see if it works...

If it does work then paired with an agile modulator (with enough power to transmit) it may become the first and only single box whole house solution to watch color on unmodified monochrome TVs.
That is if the obscure long extinct color encoding format I'm trying to ressurect works like the documentation suggests.

Are you experimenting with flicker color ( Fechner color ) perception, perhaps?

Basically. ( Good guess!) This is the article on the system I'm hoping to recreate. http://earlytelevision.org/butterfield.html it sounds like it was implemented and did work. I'd like to see how it looks in practice on a TV signal. It should be easier to count frames and use logic circuits to gate the demodulated video primaries then mix the output back into baseband video with what I have on hand than make up some camera with a color wheel...not to mention more practical for watching Video from a source. The only thing I wonder is if the slight shift in vertical rate in color video will mess with the effect (my gut feeling is it won't matter).
