Subject: RE: Huge IBM 1800 find (and need some help)
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!

Ps. And thank you for all for good advices! :D Thaaaaanks!

it causes a strong oily smell that is quickly spread

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.
