I've had to use them up until just recently. To run reverse engineering tests on an SNES console, I've had to use an old copier device. It's a box that plugs into the cartridge port and will load games off of floppy disks. (and of course, it can copy games plugged into the box onto said floppies.) Usually takes around 5-10 minutes to split an image file into four parts, write them to floppies, and then load them one at a time onto the copier. And it's only that fast because I'd do it in parallel. The disks would usually fail after a few hundred write cycles, so I stocked up on quite a few. Thankfully, I now have two alternatives. A flash cart that takes an SD card, and soon a boot loader for the expansion port that will let me load my own code through the controller port via serial. So I'm done with floppies at long last; but now my new fun is sourcing 5V-tolerant components, and card edge connectors for an extremely rare pitch size :D
