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!
