- Well, no. There's no colorburst, to begin with. You're right, that the
- basic R, G, and B signals are timed like NTSC; so all you have to do is
- combine the three with an RGB->NTSC encoder, and you've got real NTSC.

- You probably could connect one channel up to an NTSC VCR, and record the
- signal; the VCR would treat it as a black-and-white signal, and the
- playback on your TV would also be in black and white.

- Yes, and yes. Works fine. These are not NTSC-input VCRs, though :-)

-
- SGI sells such a cable, I believe; at least we have a bunch around here.
