Very possible, I never saw the insides of theirs.

MIT (was the 3rd in the series and a little later) also used 11/20s or

Thank you. That's one more "vote" in favour of 11/20. In which case
the TV-11 ought to be an 11/10 which was our original guess. I don't
think it matters to the software; it should run just as well on either
model.
I have seen MIT files which describe the Stanford hardware, so it seems
their inspiration came from there. The earliest timestamp is from
February 1973.
I got the impression the Stanford XGP had a PDP-6/10 IO bus interface
rather than going through a PDP-11. I'm CC'ing Bruce Baumgart.
