That's interesting.

DEC at one point used that same number for the VAX-11/780.  I once at DECUS was shown a secret document which was the instruction list (similar in form to the way it appeared on the "VAX code card").  The document described it as being for the PDP-11/85.

I think that was at DECUS Chicago, 1977 perhaps, and I think the person who showed it to me was the attendee from Oregon Museum of Science and Industry (OMSI -- which later became a company with the same initials but a different name).  I never saw anything more along those lines until the official announcement with the real name, but I'm pretty sure about that memory.
