If we're talking about the same thing, TENEX ran
on a modified
PDP-10.
It was a precursor to TOPS-10 (at least I think it
was).
That's what Ivan & Bert Sutherland said (it was Bert, I think) in a
Computer History Museum video on google I watched the other day.

google for "Dan Murphy" and "TENEX" for the history.
Zane will probably pop up about this at some point as well.
TENEX was developed at BBN to develop a more modern operating
system for the original PDP-10 (KA-10) processor. It required
special hardware to support demand paging (the BBN Pager Box)
TOPS-10 was the original PDP-10 operating system.
DEC hired Murphy later to modify TENEX for the third generation
(KL-10) processor. This became TOPS-20.
A couple of other variants of TENEX were developed as well; the
one used on the PARC-devoped MAXC and the Foonly (called FOONEX)
Docs for the BBN pager are scanned under bbn on bitsavers.
