I don't have an LS-120 anymore, but I did have one at the very tail end of the floppy era. I never fed it one of the fancy disks. :-/

It worked, though, and it was really fast with regular floppies. Part of me says that I should have held onto it, but the rest of me is kind of glad that I haven't been moving it from place to place for the past ~20 years.

LPT: You can plug your USB floppy drive into your modern pocket supercomputer. In what may be the funniest bit of anachronistic computing you've seen in a long time, it will show up as removable storage without any effort and you can read and write files with it. :)
