It'd be interesting to find out how well that PRM-85 works. I've laid out a
board for a rough equivalent but I haven't fabbed it out. It may be cheaper
for me to buy that instead.
I've also got a 9122C but I don't have the mass storage ROM so I can't use
it with my 85. Right now I'm using it with my 9000 series 300.

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.
