I think I can guess what you meant to say there... :)

I’ve ordered a PRM-85 (a modern reprogrammable ROM drawer replacement) which includes the HP-85B version of the Mass Storage ROM, and the Extended Mass Storage ROM. Based on what I have read, I think that should let my A model use the newer 9122C drive, and other drives using either the Amigo or SS-80 protocols.

I’d like to get the 9122C mostly because I have a much easier time finding 1.44M media than the older double density media. eBay and I don’t talk, so that limits my options a bit. If I had easy access to lots of 3.5” DD media, then I would consider getting one of the more plentiful (?) other 3.5” HPIB floppy drives.
