That's some second-hand store you have.

I have some IEEE-488 Commodore PET-era disk drives which should connect to it (with conversion since it doesn't sound like a standard GPIB connector), but they're for my PETs and I don't think there's a lot of benefit to connecting them to the LC. :lol:

Also, my HP 9000/350 has GPIB to the hard disk and floppies.
