  <div class="attr SUMMARY">
1) Question: Will the Macintosh Display Card 8*24 GC accelerate the internal video circuitry on the Macintosh IIci?<BR>
<BR>
Answer: No. The Macintosh Display Card 8*24 GC accelerates only NuBus video<BR>
cards that use frame buffering for video images. This works even better if<BR>
the other video card supports NuBus slave mode. The Macintosh IIci's video<BR>
circuitry does not use NuBus, nor does it support frame buffering. It will not be accelerated, except possibly in some very complex, pixel-deep images. This would be due to the Display Card 8*24 GC's processor and modified 32-bit QuickDraw. It probably would go unnoticed.<BR>
<BR>
<BR>
2) Question: Will the Macintosh Display Card 8*24 GC accelerate the Macintosh II Portrait Display Video Card?<BR>
<BR>
Answers: The Display Card 8*24 GC accelerates the Portrait Display Card, but the increased performance would be at the low end of the spectrum (5 versus 30<BR>
times increase).  This is because the Portrait Display does not support the NuBus slave mode.<BR>
