I recently got Atmega16 @ 14.31818 MHz to generate NTSC Color signal with the help of a shift register. More details about the project:

It might be possible to have a version of uzebox without AD725, which should enhance uzebox's retro feel. Would you be interested in something like this ?

Re: Atmega16 NTSC Color generation without AD725
Impressive! I'll have to read your articles in great details to understand. As hard as I could back then I could never figure out how to use a simple shift register to generate the chroma signal.
It sure is *very* interesting and very well written, congrats!
