Apple has a dedicated graphics CPU on one of the 24bit color cards Apple
has just announced.  The CPU is an AM29000 (DSP-- I think.  ToddPW tells
me this card is "Way Overpowered" with this processor.

Any graphics coproccessor in a Mac with NuBus must be on the far side of NuBus.
I.E.: It must be on the graphics card, because NuBus doesn't have the bandwidth
to support the high speeds a coproccessor would allow.  Therefore, the
responcibilty of providing these graphics processors falls on all color
card manufacturers.  Blame Apple, Radius, and SuperMac.  Actually, don't blame
them... They all have already come out with graphics cards with
graphics processors.  (Actually Radius's is a 2 card system w/ a non-NuBus
connection between the card, I think.)

Therefore, Since Apple has a CoProcessor for the NuBus Macs, you cannot
complain there. (Imagine: 24bits faster than B/W on a stock Mac II!)

However, I agree Whole-Heartedly that Apple needs a coproccessor for the 
B/W Macs and the Apple //.  How else to take the market from the Amiga!?!?!
