The scan doublers for the Amiga should work with a IIgs but I've never
tested it myself.  They still cost too much for me to play with but
now that I have an Amiga 500, I might need one because I only have one
Commodore 1084S monitor and it is being used on my IIgs right now.  :)

I would probably want one of the flicker-free models myself as I have
a Video Overlay Card in my IIgs and I like to use it to display 320 x
400 and 640 x 400 interlaced images on my IIgs.

The only thing that you would have to do is make an adapter of some
kind (a cable would probably be easiest) to hook up the scan doubler
to a IIgs.  It should be too much trouble.
