I've also had good results with pre-OMNIBUS PDP-8
gear by removing all
the cards, then cleaning the backplane with a chunk of manila folder,
cut to one 36-pin slot width, then dipped in >70% isopropyl alcohol
and run up and down each slot (switch to a new section when you start
to see grey streaks on the paper). That one trick has taken machines
I find a bit of 80-column punched card used in much the same way is ideal
for this... But perhaps it's a waste of rare punched cards these days :-(
