That pin tells the card if the computers are in a graphics mode or not.
I doubt that the IIgs has anything like it, as the video hardware
is substantially different.

There should be a 4 pin block that actually has the NTSC signal information
on it.  That probably won't be in the IIgs either.

If you want to use these screwy older video boards, use them on
the screwy older Apple II's (and clones).  This stuff is II+ vintage,
and there may be support hardware in the //e for it.  The IIgs
was really built for an RGB monitor, not a composite monitor; it
just happens to support composite for the heck of it.
