I have two "flippy organizers" (that's
around 20 floppies each) full
of these oddball floppies.

They are 8", hard sectored, and the sectors are on the outer edge
rather than the hub, and there is an odd cutout on one edge that goes
inside the drive.
I know I don't have a machine that uses these, so they are available
for trade.
