It was stated that the speed changes prevented the Amiga from reading all the data on a MAC drive. Back in the days of the Apple ][ (I still have one BTW), some of the nasty protection schemes used to change the drive speed. By playing with the motor select line (ie, pulsing it at various rates [pulse width modulation]) the drive speed was controllable. I did some playing about with the Amiga drive hardware back under 1.1 writing a flux editor and there is certainly no reason why the drive can't be slowed up in a controllable manner. Speeding it up is another matter, but my understanding is that the drive needs to be slowed down to read/write the disks.
