One of my first products to market, the "Berkeley Microcomputer
FlipJig", was a plexiglass "pocket" with holes, for marking diskettes
for punching the extra holes.
The "deluxe" model had a stub spindle on the outside and a ring, for
putting on hub reinforcers.

Well, that one is not the "Berkeley Microcomputer Flip-Jig"
Mine was just a simple plexi pocket with holes for MARKING the disk.
Then, the holes were punched with an ordinary handheld hole punch
I included a stationery store one with a clear blue plastic cover of the
lower jaw, to avoid scratching the disk and to catch the chad.
