Actually the IEM-4400 has a SCSI DAT tape drive and a board to interface it
to HP-IB. I wonder if that board can be made to connect a SCSI *disk* to
HPIB (probably need a new ROM though which will make the project more
expensive than building everything from scratch).
Regarding the HP Nighthawk drive I have one too (it was inside a
9153A box). When I bought the 9153A I assumed I'd find a standard
drive inside (disappointed...). Once I saw the custom drive I decided
not to bother with that drive (no way of repairing it, or recovering
data stored on it). Unfortunately I was proven right, as the drive
gave up the ghost. The Nighthawk drive now shorts the power supply.
If you remove the hard disk, the 9153A powers up, but with the drive
connected, nothing comes on, and a resistor on the drive begins to
smell! :-(

I don't think that simplifies things that much. OK I'm a hardware hacker,
but I think I could build the hardware for this in an afternoon without
really trying. Writing the firmware would take (me?) a lot longer.

I wonder if some standard part has failed, and thus the thing could be
repaired. I _will_ investigate this drive sometime, and trace out
schematics, but alas I have other things I want to do first...
