	The 24-bit SuperMac board is essentially 3 8-bit boards
(and it takes 3 NuBus slots), rigged so that one board handles
red, one handles green, and one handles blue.  So every time
a new window is plopped on the screen, for instance, three
passes are required to draw it, and this is very noticeable.
So in that respect it is slow.  However, after looking at it
at the Expo I can assure you it is worth the wait!
