I know, I was there from 1979 to 1983.  The first EMACS I used was ITS
EMACS, then Multics Emacs.  Over the years I've also used Gosling (later
renamed Unipress) Emacs, Zimmerman's Emacs, ZWEI, Epsilon, and TV.

I don't know what you've got, but it's not Multics Emacs.  I was the last
maintainer of Multics Emacs, when I worked for Honeywell Bull until they
cancelled Multics development.  It was never ported to any other system.
It wouldn't have been impossible, but it would have been quite a bit of
work, because it made use of lots of Multics-specific features.

There are a few other Emacs-like editors for PDP-10's.  For instance, Mike
Kazar at CMU wrote FINE.  However, Craig Finseth's FAQ on Emacs
implementations doesn't list any of them that use Lisp as their extension
