	Actually, you *can* read high-density Mac Floppies in any 1.44 Mb PC
disk drive. The best programs I've seen for this are Mac-ette and
Macsee, which should be in any SimTel mirror.

	It's *impossible* to read lower density Mac disks in a PC, not
because the format is propietary, but because Mac drives before the
SuperDrive used variable-speed motors for the disk drives. That is, the
disk drive would slow down when reading the outer edge of the disk. PC
hardware uses a constant-speed motor, so it simply can't read those ole
Mac disks.
