Interesting discussion by someone thinking of procuring a PDP-11/34, though having difficulty finding suitable space for it: <https://www.reddit.com/r/retrobattlestations/comments/dztvci/minimum_viable_system_for_pdp11/>

A comment that caught my eye:

That seems surprisingly pessimistic! I don't have experience with mainframes or minicomputers, but I've been working with personal computers of various kinds for going on four decades, and I have never seen hardware rendered inoperable just by being in a location that is not climate controlled.

Is there something about the technology with which the older minicomputers were built, that makes them more susceptible to moisture damage?
