As a several boxes of floppy disks slipped and fell, the question occurred ...
if you have a disk with only a vague idea of what computer it might go to, is
there an easy way to find out what computer made it without trying it in a
number of systems? Is Teledisk or Dave's program likely to be useful? And what
about Apple disks?
And to make it "easy", assume the disks all look like soft-sector disks.
