I recently decided to try out FloppyMIDI, a BeOS driver that plays MIDI music using a floppy drive.
After connecting a spare floppy drive to my BeOS PC (heeding the warnings of "This will almost certainly destroy your floppy drive!"), I installed the driver. So far, I've played quite a few MIDI files without any issues and recorded all of them.
You can find my recordings here: FLOPPYMIDI.zip
