Unfortunately, I want to use the VGA display with the Apple IIGS.  I
had a IIe a long time ago and I know what you see when you plug
the IIe into a television.  The IIGS has a better output via an RGB
connector.  The IIGS's native output is really quite clear and crisp
when displayed on its 11-inch RGB screen.  I remember it quite
well.  Even as a PC user who has a Kyro2 video card now I can
say that the colors of the IIGS paired with its RGB monitor were
stunning.  The IIGS only had 4096 of them but they were put to
good use.  There was NO color fringing on the RGB output.

So that's what I would like to do.  Get that display on VGA.  Not
the NTSC composite output.
