To the best of my knowledge, TSS-8 was written by Bob Clements (RCC) and
another DEC engineer, who wanted to create a monitor for the PDP-8 similar
to that for the PDP-10 (of which Bob was one of the designers).  This idea
is based on personal communication from Bob when he visited the museum for
our grand opening in April 2013.

I don't recall any mention of CMU in his story, but perhaps the other person
was from CMU.  I can ask him, of course.
