     The fastest official 68040 Mac was the Quadra 840AV, which ran at 40  
MHz (mind you, all 68040's were clock doubled, like 486DX2's, so I guess  
you could stretch it a bit and call it an 80 MHz). The PowerPC 601 based  
systems (6100, 7100 and 8100 went from 60 to 80 MHz in their first  
generation (I own a couple of the 8100/80's). I don't know if Apple had  
prototype 68060 based machines... I would guess not, as they did the big  
PowerPC announcement with Motorola and IBM years prior to when that  
generation of chips came out.
    The original Mac prototypes, on the other hand, did originally have  
6809's in them...
