The main problem is that this monitor has a scan frequency double
that of the IIGS video port.

You can use it, but you need a Second Sight SVGA card from
http://www.sequential.com/ Sequential Systems.  Otherwise, you'd
need to run the scan frequency of the monitor down yourself if
you are a qualified monitor tech.  Jim Poore, who used to post to
csa2, wrote about how to do it some time ago.  Do a search on
http://www.dejanews.com/ DejaNews for the article.  Final warning
is to be very careful...lethal voltages in monitors, even when
unplugged for some time.
