I have to agree. I did this a long time ago to a damaged PDP-8/L (broken
wires, broken enclosure, missing front-plex and broken front panel...)
At the time, I had two and had _no_ prints. I still have the net-list I
made from dismantling it (but it's of no value now that I have real PDP-8/L
prints).
I wish I hadn't done it now and I can only plead youth and ignorance (I was
16 when I got the pair of -8/Ls).
The point of this is to say that completely stripping the backplane is
probably a one-way activity. Documenting and removing the cards and
cleaning the slots (with a sliver of manila folder soaked in isopropanol)
on the other hand, is a good idea. That is entirely reversible.
