One example of a proprietary Emacs was Gosling Emacs, which started out open source (of a
sort) then went proprietary as Unipress Emacs. It was nowhere near as nice as GNU Emacs once
that matured, but it was around before that - early 80s at least. I once wrote a filtering
newsgroup reader based on Gosling Emacs - this tool worked quite well but dealing with the
fairly horrible and slow Mocklisp included in that Emacs was painful...

My recollection of Gosling Emacs was that the embedded language was more C like than Lisp
like... I might even still have a manual in my basement somewhere.
