Untrue.  I've both created and read 400K disk images with Disk Copy (and
DART) on various PPC machines running upto OS 9.
This includes some Powerbooks as well as a TAM and and 7100.

You do not need System 7.5.  All that's required is Disk Copy and a
SuperDrive or 800K floppy drive. (USB floppy drives will not work.)

If you wish to read the files on MFS you need System 6 (or MFS lives on
OS X).
