A friend just sent me a pointer to this site, which appears not
to have been mentioned on this list before:
PDP 11/70 Emulator
http://skn.noip.me/pdp11/pdp11.html
The site lists these working guest O/Ses:
RL0 BSD 2.9
RL1 RSX 11M v3.2
RL2 RSTS/E v7.0
RL3 XXDP
RK0 Unix V5
RK1 RT11 v4.0

All, I've got the original PDP-7 cat working in my PDP-7 user-mode
simulator called "a7out". The cat.s source code and the a7out program are
in the Github repository in src/cmds and tools, respectively.
The repository is at https://github.com/DoctorWkt/pdp7-unix
The mailing list is at http://minnie.tuhs.org/pipermail/pdp7-unix/
I'm attaching the a.out assembly output as the as7 assembler in the
repository currently is not quite ready for cat.s.
To run the original cat, create a text file, e.g. echo hello > file1
$ ./a7out a.out file1
hello <- the output of the PDP-7 machine code
Cheers, Warren
P.S Thanks again to Norman for getting us the scans.
