I just checked my 9122C I happen to have open and the interval between
index pulses is 199.66mS which would be 300 RPM, which is good news for
me I can now proceed with adapting a more common 1.44 drive to replace
my broken one.

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

Yes it does. I have an HP 85A, the PRM 85 and a 9122, and that combo works
beautifully.
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!

Yes it does. I have an HP 85A, the PRM 85 and a 9122, and that combo works

I could check that if you want.

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

Hmm, I'll consider yours if a more workinger one doesn't appear. That
