Arck, I'm a moron; Paul has pointed out to me that this is, in fact, online
at Bitsavers:
http://www.bitsavers.org/pdf/dec/pdp11/handbooks/PDP11_BusHandbook1979.pdf
It didn't show up in a coup
I like the fact that https://williambader.com/museum/vax/pdphistory.html
shows a cover image plus identifies the marking on the back cover
("EB-17525-20/79 070-14-55").
https://authors.library.caltech.edu/5363/1/MARprocieee06.pdf cites it in the

I recently acquired another PDP-8/E and wanted to test basic CPU functions and
memory before I added peripherals. There are some available short "memory
tests" online, but most don't have have the flexibility to test multiple data
patterns by design.
The test below does a classic checkerboard type
Continuing the debugging of my recently acquired PDP-8/E, I wrote an address
test that's easy to enter from the front panel:

# Pass 2: Tests each location for the correct address. If

Another PDP-8E? You are very lucky :)
