Yes, the OS allows entering of drive geometry. Actually only supports
MFM up
to 70Meg. RLL drives will of course work, just not to RLL capacity. I'm
looking for the largest drives I can find.

Hmm... those aren't so common (in the DEC world, there are two
choices - the RD53 (Miniscribe 1325) and the RD54 (Maxtor XT2190).
I take it you aren't constrained by a narrow set of expected
geometries? (i.e. - you have a running system and/or the install
procedure asks you about the drive rather than assuming?)

I seem to have only up to RA81, but everything else :(

Subject: Disk drive head locking (DEC RA-82 and HP 7920)
Hello,
I'm scheduled to pick up a pair of DEC RA-82 drives along
with an HP 7920 drive in the next couple of weeks.
I don't have any technical documentation for either of these
drives, but I'd be very interested in learning the proper
procedure for locking down the heads on these drives
prior to moving them. If anyone has the steps to take
for either or both of these drives, please drop me a note
or point me to the proper archive.
They've already been warehoused, so it might be too late,
but I'd like to be as safe as I can.
Thanks!
Cheers,
Dan

It seems, that Olkiluoto 1 still has the Norsk-data machines. They will change
those next year, so they might still keep all that hardware in stock for some
time until block 1 is also modernised.
If someone likes to save equipment, doc's or photoos, its time to act now...
(too far away for me...)
BTW, back in the seventies I was working for a large finnish company that build
(parts of) the security shutdown system of the Lovisa npp. They also build the
npp-operator's training simulator and I remember that it was using several big
Eliott computers from UK. What happened to them? I mean Eliott, not N...a

A good PAT tester will check at a sensible current (though admittedly a
lot only check earth continuity at a proper current). As for strain
releif, well you're not supposed to swing the equipment by the power
cable, Tony!

I've a feeling I've seen this used somewhere -- but not recently, and I
can't think where :-(

I'll see what I can do. Maybe I can scan them at work. Just
found out my UMAX scanner doesn't work under Mac OS X.
