AFAIK they use variable speed to using a PC drive to read/write Apple
3.5" disks is at least difficult.

Wouldn't it be possible to cleverly emulate the variable speed zones in software by playing with the data rate?

I thought about it - that's why I said "at least difficult" rather than
impossible. In fact reading may not be too hard, but writing is a different story. Since the device requires almost no hardware and all the programming is done on the AVR side, it is easy to experiment. I mean the prototype doesn't even need to be connected to an Apple - just a serial channel to a PC or a Linux box.
