  • One more interesting feature was the “write lock” switch on the 3.5" ones, a sliding button that covered one of the squared holes on their edges. The floppy drive would sense that and refuse to write on them.

    On the 5.25" it was a notch cut on the side (there were punchers for that). To write on a “protected” disk, you’d cover the notch with adhesive tape.

    It’s the guts of 3.5" floppies, like these, they usually stored 720kB, then 1.44MB, but the latest versions (double sided) were 2.88MB.

    The larger one at the bottom is from a 5 1/4" (orange in this picture, the big daddy in the picture is 8", first type I used, with COBOL)

    … and now you kids know where the “save” button icon came from.

    They were not meant to be removed from their protective envelopes, they’re probably damaged now.
