Good deal. I guess I'm just gonna go for it after a cursory inspection and
dusting. It has stayed utterly dry; just the temp and dust were concerns.
I'll report back in a while.. Thanks!

At the very least, take a good long look at the power
supply and its caps.
Has the storage, as bad as it's been, been dry? If not, you'll almost
certainly have corrosion all over the place, especially in the fastons ISTR
run power to the backplane. (I haven't looked at my own 11/73 in a few
years, but it's in a dry, temperature-stable basement.)
Best of luck! - Ian

Hey all,
I've been getting the bug worse and worse to start working on a real
pdp11. The Raspberry Pi / simh emulation is fantastic, but my hunger for
authenticity is becoming rampant. I haven't run the youngest in my fleet
of pdp11s, the 11/73, since circa 2002 and if I recall correctly, it was
becoming flaky and popping out to ODT inexplicably from time to time back
then (I think this is the one with the notoriously combustible power
supply
wires that probably haven't been ECO'd
yet -- need to get to that too).
It's been lying in a warehouse in western Pennsylvania with no heat and a
lot of dust. So, worst case, we're talking temperature transients around
110 F and -20 F with no protection. It did stay quite dry.
Think it'd be bad to simply blow the dust off and fire it up?
thx
