hp 9000/300-320 68K, Questions

Well, it'll work in that neither end will emit magic smoke. But whether it does anything useful depends on the software running on the 9000. As I understand it, the earliest HPIB drive units (mostly floppies, but the HP9133V ans XV hard drives are included too) used a command set called 'Amigo' Later untis used either CS/80 (Command Set 80) or SS/80 (Sub Set 80). THey are very different. Unfortuantely that hpdrive program is only supplied as a binary for a proprietary OS, so it's not something I'ev looked at. Making an HPIB 'drive' using flash memory cards (or USB sticks), a microcontroller, et is one of those projects that gets talked about here from time to time but which nobody has ever doen. It certainly would be useful. Not so. IIRC the 9121 is Amigo, the 9122 (and 9123 [1]) is SS/80. [1] This is a special drive unit for the HP150-II. It has no internal PSU, it takes power from a special DIN socket on the HP150-II. Electronciing it's quite different otother HP drives, logically it's an 9122
