Ken,
years ago, when I ported V7 to my own microprocessor ECO32,
I wanted to have a stable reference running on a (simulated)
PDP-11 in order to better understand some difficult corners
of the original implementation. The set of files I used can
be found here (and the archive's docs say "This set of files
from Keith Bostic looks like the original tape records from
the 7th Edition distribution tape."):
https://www.tuhs.org/Archive/Distributions/Research/Keith_Bostic_v7/
I had a few minor difficulties to get it running in simh,
mostly centered around the tape format and the configuration
of the simulator, but finally I was able to install V7 exactly
as advised in the manual ("Setting Up UNIX"). I packaged the
whole adventure (original files, simh, scripts) together with
a HOWTO:
https://homepages.thm.de/~hg53/pdp11-unix/
On this site, you can also find all files extracted from the
V7 file system to the host (Linux in my case).
If you have questions, I will be glad to help.
