And I do mean "haul".
I found the stash at work today, and dragged it home.
I had already copped the DEC 3000/300x Friday, and my boss told me he
thought there was some more of that stuff around somewhere. So I
snarked it.
3 DEC 3000/300x
2 untested as yet, w 2xRZ26E each and looks like 64M RAM
also MAGMA 2+1 TC (serial/parallel adapter?)
1 w/2xRZ26E and 80M RAM. no MAGMA
booting OSF/1 v3.2, Oracle
1 Mouse/KBD breakout w/mouse.
1 DEC SZ12 expansion unit with an RZ58 and a Seagate ST32430N
1 DEC MicroVAX 3100-90 w/serious problems - system board looks like it
was wet & powered up. :o(
Boots to console, but gets errors at several checkpoints and
ends up with "normal operation not possible". Haven't done much
trouble-shooting.
Looks like 128M RAM
*** RRD42 - with "OpenVMS v6.2 Binaries 1 of 1" in caddy!

1 VSXXX-AB Graphics Tablet & Puck. untested, and haven't found the

Do the RZ26-E drives always sound like a gravel-crusher, or are all
these toast?
All this cool stuff, and the other day I was heavily lusting after an
MV3100-30 on eBay, and right now I'm just p*ssed because the '90 is
broken. Spoiled, huh?

First thing I'd do is clean the board. Mineral deposits and such from
cooked water cause all kinds of weird problems with boards. I've cleaned a
large number of boards that were exposed to water (even ones that went
through a flood), and most worked fine after just cleaning. A few needed
minor repairs, but were otherwise in good shape. Switching power supplies
don't tend to survive water at all though.

Yep. My only excuse is that it was sorta dark in the garage, and I
couldn't see the deposits on the board till I got out the flashlight.
I'm going to give it a good cleaning (don't go near there!!) and an
OptiVisor inspection this weekend. It gets close enough to booting
correctly that I'm hopeful, if not at all confident.

If they're powered up at the time, I can see why (non-pure) water
would do all sorts of damage to an SMPSU. But if they're not turned
on, and if they're cleaned and dried before being turned on again,
then I see nothing that would be damaged by water. I keep on emphasising that if you get a machine in

First thing I do to any equipment I buy that is used is completely break
it down for cleaning and inspection. I repair anything I find suspicious
before ever powering the equipment up. I've actually waited years on some
equipment before ever powering it up. Less magic smoke gets a chance to
escape that way...

Nice haul! I'm jealous.

If you hear strange noises during seek operations, this is a "special
feature" of the disks when mounted in a 3000/300X (IIRC): the box seems
to act as a resonator for some (not much!) noise coming from the drive,
so it will sound like it's scratching the bits into the disk's surface.
So, as long as it happens only when seeking, don't bother about it, or
redesign the box to avoid the amplification effects ;-)
