Try checking out "Inside Macintosh", sometimes that is helpful. If you
are using Linux there is a patch to the kernel so that you can read mac
disks. That also might be useful ... check out sunsite or tsx-11 if you
For a 1.44Mb disk, I believe the sector size and GAP value are the same
as PC 1.44Mb disks ... what is different is the boot sector, FAT and
directory stucture. For 800k disks, Anthony was right ... you need a disk
drive (or controller) that will let you alter the read/write speed of the
disk head, and unless you want to program the floppy controller yourself
(email privately for details) it can't be done.
