Quam built a Nova to XGP interface at Xerox Parc

Anyway, I'm pretty sure the [XGP] copies at Stanford (Jan '73), and
MIT (was the 3rd in the series and a little later) also used 11/20s or
maybe 11/15's which was the OEM version of the 20 as it was March '72
when the CMU XGP was first stood up.
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.
