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 bug daddy in the picture is 8", first type I used, with COBOL)

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

This reminds me of when I got a new PC when I was younger and I was shocked… “WHAT?! THEY COME WITH 128MB RAM NOW!!! AND THEY HAVE A DVD TRAY??? No more floppy disks!!!”

Fuck, those were nice times (except for dial-up internet).

The part that’s wild to me is I have an SD card in a computer in my pocket that cost $10 or so and is basically disposable but it’s larger than the hard drive in my first computer from 25 years ago
