So what exactly is the Mac HD20?  Is this just an external SuperDrive?
I have connected a SuperDrive to my CPS UDC (half-sized I'm guessing)
but it only recognized the drive as an 800K which I believe to be
a limitation of the firmware, but perhaps in the hardware, as well.

If I had a UniDisk 3.5, I'd test this out.  Unfortunately, I don't think
a Macintosh external is the same thing.  In fact, I distinctly recall
the the UniDisk 3.5 having a 6502 built into the drive case.
