People might remember the faux-cassette tapes with an analogue audio input, that you could use to play music from other sources on a tape-only car stereo.Does something similar exist for legacy floppy drives? Like a fake floppy with a micro SD card slotted in.
Packing it into an actual diskette might be challenging - I guess you'd need to read an encoder on the rotation. Perhaps if you had some legacy musical or scientific instrument with a tape drive you'd be better swapping out the whole drive with something that presented as a floppy drive to the device?
A device like this exists for Apple II floppy emulation. I've not seen one for PCs, and modeling it as a floppy would have significant downsides to the alternative, just modeling it as a removable (hard) drive
