I'm glad this thread started (reading non-DOS diskettes)....
I have been toying with trying to get my PC/AT to read OS9 diskettes.
Os9 typically uses 256 byte sectors, and also has a description
of the media in sector 0 of the disk (although I would bet it's
not in DOS edible format). Is there any mechanism (short of directly
diddling the disk controller) for reading 256 byte sectors?
To throw in a worse curve, some formats of OS9 floppy disks have a
single density track on side 0, track 0 to support prehistoric boot
EPROMS on several machines. Will PC class disk controllers even DO
single density?
Thanks for any help or hints!
Pete
