Can this be done?
It looks doubtful so far, but it never hurts to ask.
nope, not possible. I looked into this in the past and what I can tell is that the chip emits Y and C (S-video) video lines and then combines them into composite. You can identify the seperate Y and C by the 2 choke inductors on the board. So S-Video is the best quality you can get out of the Radica. Stereo is possible as well.

Hey, it's better that the insanely blurry composite that thing puts out.
Maybe S-video will bring it up to normal composite standards...
Then perhaps I'll build myself a portable.
