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.
