But some work toward that must have already occurred, because at so-called
KansasFest an Apple employee demonstrated a 640x400 version of Finder (with
a few remaining glitches, but mostly functional).  Completion of this work
would be very nice, or I would even be happy to obtain the preliminary hack.

Thanks.  When launched from GS/OS it worked but didn't return properly
after termination.  A nice demonstation of the capability, though.

If it's not too much trouble, I'd appreciate it.  Is there some published
work giving programming information?  The manual accompanying the card is
Apple's typical dumb-user guide and gives no useful information at all,
apart from how to install the card and run VideoMix, which needed no
explanation.  (Well, actually, the requirement that the card be installed
in slot 3 in a IIGS surprised me.  Is this a deficiency in the support
software or does the card rely on something magical about the slot 3
signals?  I had to move my FPE to slot 6, which was the least bad of the
options I had available.  I guess this is my last Apple II bus peripheral!)

That would be nice, since MANY GIF images have more than 200 lines.
