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:

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.

it causes a strong oily smell that is quickly

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.
