For the record: the Adaptec 1542B ISA bus SCSI controller includes a
floppy controller that's compatible with the one in the original PC, and
which can be programmed in minute detail for tracks, sectors,
interleaving, inter-sector gaps, and so forth.
I used one of those and a modified NetBSD floppy driver to create boot
floppies for my Osborne 1, after downloading images off the net. :)
