IBM invented the 8" floppy disk format. Generally their disks follow the standard

I've got a pretty good pile of IBM 8" disks,from System/3 to
Displaywriter. If you've got a PC hooked to a standard drive that can
handle FM recording, you're good with IMD and a few other packages.
If you've got any of the 8" "magazines", they open easily and the
disks
are straightforward 8" floppies.
