Q:  What is the sync frequency of the monitor?  Actually, it is very
likely that you might be able to use such a monitor with the IIgs, but you
will need to obtain a cable to split the red, green, and blue inputs from
the IIgs RGB output and send them to the monitor.

This is assuming, of course, that the monitor does indeed have separate
red, green, blue (and possibly sync) inputs.  Just because the monitor has
BNC connectors does not necessarily mean it has RGBS inputs.

It just so happens that virtually all professional composite monitors have
BNC connectors; it is equally possible that the BNC connector on the
monitor you are looking at is merely a composite video input...you can
actually get adapters (on the order of $3 from Radio Shack) to connect
your RCA video cable to the BNC input.  Trouble is, that's the same signal
that you *didn't* want to use in the first place.

Caveat emptor!
