That's true...both cards are for 8-bit Apple II's--my mistake.


Even with the bugs, at least it basically displays VGA and I think
that is all anyone is looking for at this point. Just something to
play with.

But there are proven and affordable ways to convert IIgs RGB to
VGA.  Those methods are *completely* compatible.


Could you point me in the direction of one?  I've been following this issue
for some time, and all the ones I've seen on this newsgroup are either hit
and miss (the Highway 100 converter) or have nasty conversion artifacts that
make them unusable for a IIgs monitor replacement.

The "conversion to VGA" route I was referring to was the Highway 100
converter, so if that doesn't work for you, we're still waiting.
(The other methods were Apple RGB to SCART RGB or Component video--
but at NTSC scan rates, not VGA.)

The problem is that attractive conversion of IIgs RGB to VGA depends
on characteristics of the converter that are not usually specified,
and so are hit-or-miss unless someone actually tries one and finds
that it works well.

The reason for the problem is exactly the same as the one that Alex
Freed addressed in his recent mod to the //e VGA adapter for Carte
Blanche--the need to resample Apple video at a non-optimal rate.
