Why don't you just connect your NTSC machines via the composite input?
You won't get a better picture by adding a SCART connector. What you'd
need is an s-video input. In my 1084-P the only difference between
composite and s-video is a grounded inductor. I guess it is used for
filtering the color part out of the composite signal. When using already
separated video, the filters are not needed anymore and can be bypassed
or disabled. This will result in better video bandwidth.
