I _think_ the Amiga 3000/16 had a 16Mhz 68881 and the A3000/25
had a 25Mhz 68882, but I could easily be mistaken.
My memory is that the parts were interchangable in hardware (presuming
the speed was OK) but the performance was better at a given speed
for the 68882 over the 68881. I never did any rendering on my Amigas,
so my use of the floating point was rather limited. I skipped over
the '020 when I was heavily into Amigas, leaping from a massively
expanded A1000 (Rejuvinator, Spirit InBoard, Microbotics Starboard w/Star-
Drive, ROM switcher, etc.) to an A3000/25.
