Yep, I've been meaning to do that for a while.

Hi Eric,
It's not urgent, but when you have a chance, could you dump the 9122C
ROM(s) and take high resolution photos of the controller board?
Since it does HD, I suspect it probably does not use a 600 RPM mechanism.
Thanks!
Best regards,
Eric

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.

Extended
wondervifcthec9122 drives,will work on 85?
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 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.
