Boost if you're old enough to know why I have one of these on my computer desk.

You can make the flip side usable or, if you’re bad enough at it, both sides unusable.

@rk I see all the references to 5.25" floppies, which I knew well, but I have never used a punch with one. What does it do with a floppy?

You could use a hole punch to make another write notch on the other side of a single-sided floppy, doubling your disk space (though at the time most drives could only read one side at a time).

Some disks were also shipped without a write notch at all, so that you couldn’t replace whatever was on them; a hole punch gave you a free reusable floppy!

@rk I used to own a square hole punch that had a spacer that aligned the floppy to the exact position for the hole. I was a hit at the BBS parties, let me tell ya.
