It'll take quite a bit more than a simple modulator, I'm afraid. The compact macs use 
horizontal scan rates that differ from PAL or NTSC, and the vertical scan is 
non-interlaced. Even if those weren't problems, the bandwidth of mac video is about 
triple what an ordinary TV video chain supports, so only large objects will be 
rendered ok.

If you have infinite free time, love a challenge, etc., you can find the pinouts (and 
a detailed description of the video circuits) in the Mac Plus tech info at 
http://home.earthlink.net/~gamba2.
