Thera are 2 kinds of floppies an 360 kb and another in High density 1.2 Mb.
But, with a tool, I cut a small hole at left floppy and I double the
floppy. goes to 720 at total
I have that tool in my Museu.
Are you talking about a jig to modify a single sided diskette, so that you
can flip it over and use the other side as a single sided diskette?
(called a "flippy" disk)
Are you just punching an additional write-protect notch (suitable
for Apple, Commodore, Atari) or are you punching an additional set of
index hole access holes?
The first such jig that I'm aware of was sold by Don? French.
(sheet metal with tabs to hold the disk against)
The second one was the Berkeley Microcomputer Flip-Jig.
(plexiglass pocket jig)
