I ran the existing lumma signal to the lumma input of my Commodore 1702 monitor and the new chroma signal to the chroma input. Yes, it does work fine. However, I have to say I can't tell the difference between using the new chroma signal composite video into the chroma input. Both seem equally good. I guess I can see now why Atari did not bother with the separate chroma when the designed the XL. Notice that I am talking about running composite to chroma input. If I run composite into the composite input, the picture quality is distinctly inferior. Just curious...has anyone else (perhaps someone with an 800 non-XL) tried substituting composite for chroma? Can you see the difference? Thanks for all your help. Burns fisher%star@DEC.COM
