Do repositories of MNOS and DEMOS operating system source
code or binaries exist? Do either of these run on simh
or other simulators? (were the PDP11 and VAX11 knockoffs
close enough matches to the originals?)

There is this..
http://pdp-11.ru/mybk/pdp11/DEMOS.RAR
which looks like a bunch of disk images, but they didn't boot for me either
in SIMH or a few russian pdp-11 emulators.....
Although a little bit of googleing seems to reveal that the soviet pdp-11's
had video cards, and were geared more as "PC's" then as mini computers...

After extracting the *.DK from the RAR archive, I found that U1.DK is a tar.
the bin directory contains:
[ cc cp df echo file ln make nice ps restor size su
time wf
adb chgrp cpfd diff ed find login man nm pstat rm sleep sync
touch
ar chmod csh du expr grep ls mkdir nroff pwd rmail sort tail
true
as chown date dump false kill lx mount od re rmdir strip tee
umount
cat cmp dd dumpdir fgrep ld mail mv passwd red rpl stty test
wc
All of the above are PDP-11 executables.
A "TEST" directory contains:
ctest.c: ISO-8859 C program text
f77test1.f: ASCII text
f77test2.f: ISO-8859 text
hdr: ISO-8859 text
kcgd: PDP-11 executable not stripped
main: ISO-8859 text
primer: ISO-8859 text
printend: ISO-8859 text
PROT: ISO-8859 text, with escape sequences
run_test: POSIX shell script text
t1: ISO-8859 text
t2: ISO-8859 text
t3: C shell script text
t4: ISO-8859 text
t5: ISO-8859 text
t6: ISO-8859 text
test1.sc: ISO-8859 text
test2.sc: ISO-8859 text
test3.sc: ISO-8859 text
test4.sc: ISO-8859 text
text: ISO-8859 C program text
text.std: ISO-8859 text
Will futz around with the other .DK files when I have more time...
which looks like a bunch of disk images, but they

Perhaps they are Dectape or other tape type???
