I just visited see 1800 (900 km of driving! I'm little bit exhausted...) and we had
big time with plant manager when we went throught the stash! I think I have infected him
of old computer disease, he had very excited this project too, haha! :) Original plan was
to pickup some small items today, but it was impossible, because of all my hurry at work
:/
But now I have good, interesting and of course, bad news ... Lets take the bad news
first: it seems that machine have donate some parts as can be seen at the pics. That
company had another 1800, maybe some parts have been picked out for it... Also there is
"small" dust problem, it is every freaking place!
Then interesting news: it have been used to since 1986, longer as I excepted. Second, and
more interesting fact, that same warehouse had used as mushroom farm ;)
Good news: There is documents every where! Just quick look, and I found tens of IBMs
original documents! And also it is still fully enough to fix it up. Some spare parts are
laying around and almost all stuff what is know used back then, is still there (except
Tektronix displays, GRRR!).

And that moving... Somebody recommend sleigh and thats really only option, it is absolute
enourmous work to but it small pieces. I have to make sleigh of RHS beams, plywood and
polyamidi slides. This whole set is lowered on stairs by winch. That's the plan and it
should (and would) work!
More coming later! Now I have to sleep!
Oh, the pictures:

We had a 1620/II in college with a pair of 1311s, which are similar to the 2311. The
system drive sprung a leak. The field service tech replaced the failed seals, and I
obtained some reagent grade isopropyl alcohol from the chemistry department. He used that
with Kimwipes to clean the oil from pack and heads. The result was complete success.
Packs and heads in those days had tolerances far larger; I wouldn?t want to try that with
anything much newer. But if you have a 2311 with contaminated heads or packs, you might
give that technique a try.

This one wasn't when I was there. I think we also had a oil spraying event
there, but it was relatively contained. We had one at Washington University, also that
might have contaminated several spindles before they got all the packs unloaded.
I think this one is fairly quickly detected if the computer room is occupied, it causes a
strong oily smell that is quickly spread by the A/C system. OK, a quick search shows the 2311 was indeed
hydraulic!
The University of Missouri, Rolla 9 drive 2314 was hydraulic, and on
night a drive's actuator unloaded into the pack area, and took it out, but the damage
from that major failure was contained w/o the pack or actuators exiting the enclosure.
however the debris took out all the packs and drives.
