When I started playing with PDP-11's in 1986, they gave me a
messed-up 11/40 system which didnt work. The sys admin said
it used to work fine, so I had a good chance of getting it
back to life by cleaning out each and every part, stripping
the backplane, and then rewiring it.

So... I did. I spent the next 3 weeks with a wrap-gun clamped
in my right hand, a magnifying thinger on my head (I looked
like a surgeon ;-) and lots of paper around me.

The good news is.. it DID work afterwards. :)

Obviously, a -7 is *much* more work, but assuming Tor as the
complete wire lists and module locations, and LOTS of time,
he should be able to get that back to life, too.

Good luck, Tor.. I still have my wrap gun, you can borrow it
if needed!
