This story appears today in The Register:
PDP-10 enthusiasts resurrect ancient MIT operating system
Incompatible Timesharing System now compatible with modern machines
https://www.theregister.co.uk/2017/01/30/pdp10_enthusiasts_resurrect_ancien…
Near the end of the story is a mention of SIMH and of KLH10, both
of which emulate the PDP-10. There is also mention of a PDP-11
emulator running inside ITS.

Hmm, does the PDP-11 item make this on topic for TUHS? :-)
There is actually a lot of PDP-11 software in ITS, because 11s were used
all over the place as dedicated processors to control hardware devices.
There's a cross assembler called PALX, and several debuggers called RUG
and CARPET.
No Unix though.

Warren - please correct me if I am mistaken/changed this since the last
time I checked up on these things, the PUPS mailing list was retired as the
URL for the PUPS mailing list on the PDP Unix Preservation Society Home Page
<http://minnie.tuhs.org/PUPS/> says it is out of date and tells people to
go to TUHS and the mailing list URL Subscribe to the PUPS mailing list
<http://minnie.tuhs.org/mailman/listinfo/pups> comes back as "No such list:
*pups*"

Yes, a while back I merged the two mailing lists so we have only TUHS now.
I don't mind a bit of off-topic posting, but an on-going thread which
isn't related to Unix isn't so good.
Cheers all, Warren

In the wikipedia entry on the DEC PDP-10, it has this comment:
"The PDP-10 is the machine that made time-sharing common, and this and
other features made it a common fixture in many university computing
facilities and research labs during the 1970s..."
Is it a reasonable claim that the PDP-10 made time-sharing "common"
(note it says "the machine")? I'm presuming that "common" should
be
read as ubiquitous and accessible (as in lower-cost than
competing/alternative options from other manufacturers or even DEC).
I'm wondering if it was really the combination of the PDP-11
(lower-cost more models) and Unix ("free" license to universities)
that propelled time-sharing, at least at universities.
