I wonder if one could use a PIC chip to do it. They'll do 20Mhz, and they
like bits.

But that doesn't mean that's the only way to
read such disks. The format
(as in just what pulses appear where on the disk) is pretty well
documented. It wouldn't be that hard to use some random logic or an FPGA
to make a disk controller that read apple disks and transfered bytes to
whatever host you wanted to use.
I would guess the pulse rate is going to be low enough that modern CPUs
could read the pulse-stream off the disk directly and decode it. I'm not
going to try it, but I would be very supprised if it couldn't be done.
