Hey I remember your posts from back in the days of
Nathan.  Glad to see you are still using the IIGS.

As for the Second Sight, I actually have one but that
is not what I am after.  My Second Sight can display
on my PC monitor all right but it does not support
the modes I want to use such as 3200.

Technically, the IIGS RGB to component video out
adapter cable should be easier to design than an
SVGA to component video because TV component
video operates at the same 15kHz scan frequency
as the IIGS and component video IS RGB.  ;-)

I suspect that it is a simple matter to wire a cable
with the 15-pin IIGS RGB connector at one end
and the four RCA plugs (luma, red, green, and blue)
on the other (or is it just red, green, and blue...I
don't own such a TV yet so I'm not sure if luma is
split off).  No electronics should be necessary.
