Very useful to see as I ponder trying to get my 11/45 (with a KB11-D in
it) going again. I think next time I work on this beastie I will roll
it out from my main room where the lighting and access are just OK into
my larger room where my PC is kept temporarily, for easier access.
Going to want to buy a load tester and thoroughly check out the power
supplies first - which are unfortunately really heavy (and may not be
mounted quite properly, either), as it has been several years since I
turned the thing on.

From the blog
of someone who got a KB11-A working
It's Fritz Mueller's blog; at about the top of this page:
https://fritzm.github.io/category/pdp-116.html
he's just turned the machine on for the first time, and you can
follow as he chases, finds and fixes CPU problems. The KB11-C/D
of the -11/70 is _very_ similar to the KB11-A he was dealing with
(they are _basically_ the same CPU, with a cache, and other stuff
added on the other side from the CPU, on the KB11-C/D), so there
are probably some good lessons to be learned.
