[stuff deleted]
Since we are on the subject, I have a question regarding the operation
of the accelerator itself:

Does it replace the 68030 CPU on the motherboard completely, ie: disable
it; or does it act as a sort of a co-processor? It would seem like a 
big waste to have a 68030 sitting idle on the motherboard if it can be
utilized to handle stuff like i/o and possibly quickdraw acceleration?

Is what I described anywhere near the truth or even feasable?
