Does anyone have any information about these HP hard drives?

Model 97500-85620.
They have a 40 pin connector on them, but no power input. Doing a search
shoes a mix of companies describing these as either HPIB or IDE. I
believe HPIB is probably the case, but I can't find any documentation for
the drives to be 100% sure. I would love to find a manual/spec sheet for
the drives.
Thanks!

Those are 10 Mb drives used in the HP 915X and HP 913X series drives.

They also can be used in the first series HP Vectra in combination with the HP 45816A
controller.

They are 20 MB MFM drives with a proprietary interface. I have at least a
dozen of them, coming from old HP Vectra PCs. I also have a HP 4972A
network analyzer that has one built in. The Vectras used a special
controller (8 bit ISA) with a 6809 and a BIOS. I also have those cards;
they work well in other ISA bus PCs (successfully used them in Pentium
class machines). IIRC the transfer rate is inferior (4 Mbit/s?) to the
usual ST-412 MFM rate (5 Mbit/s). But I really like the sound of the
actuator, similar to a ST-225.

Is this a little (3.5"-ish) winchester drive? If so, it was used in the
HP Vecta (some models) and in some HPIB disk units.

If it's the drive I am thinking of, it's not HPIB. The interface is
strange. It's 'raw' read/write data and an 8 bit data bus + control lines
ot position the heads, etc. There was an HP custom chipo used as the
controller, but I've never seen one 'bare' or seen a data sheet for it.
There was an HPIB controlelr for it, used in the 9153 and 9154 drive
untis (the former includes a floppy drive, the altter doesn;t).
You might take a look at the Australian Museum site
(http://www.hpmuseum.net) and look at the HP9153 and 9154 drive units.
There are some manuals on thsoe whihc will, I think, at least give a
pinout of the connector
