The jumper part of the M941 I can probably help with; I don't have any real
M941, but I think the extender part is used with some test equipment or
other.

My TU56 arrived and I spent some time looking over it. It is missing a
G742 module, but has a "homemade" card in its place. It is also missing
two M941 jumper/extender cards. Otherwise it appears to be complete.
I need a couple of empty take-up reels. Does anyone have any of these
or the G742 or M941s? I don't want to waste decent DECtapes just
to get empty reels. It is quite dusty and has some cat hairs on it.
I'm thinking I should
dis-assemble some of it and get rid of the dust that has adhered to most
things. What's the best way to clean the backplane to restore it to what
should be a functional, clean condition?
Knowing where you got it, I'd guess those are dog hairs :-). Sorry no
advice on removing it, except perhaps to try to gently vaccum it out.
I looked at the capacitors and they don't appear
to have leaked (yet).
I also discovered that it likely has not been powered on since 1989.
Would it be prudent to go ahead and replace the capacitors, or should
I use the "power up slowly" method described by others so the the
capacitors can be re-formed?
I though he had powered it up more recently than that (though probably for
only a few minutes).
