No such luck for me. I have two monitors that will not produce color from
an NTSC signal. Have you tested this yourself. It is possible that my
monitors may be broken. If you have a way of checking this please do. It
will save me a lot of time if I know they are broken for sure.

I also used a green screen as a TV monitor some time ago. I had no
problems with that displaying a good picture. The AppleColor has been a
different story though.
