EMACS Version 162.43z ?

[Peter Tury]

Hi,

I have access to an ancient VMS through terminal. It has Emacs and I
can use it. :-))) It's version is (got for M-x version) "EMACS Version
162.43z". What does this mean compared to v21.4, v22, v23, ... what we
have nowadays? Do you know its release year? How can I figure it out?
I googled for it and saw somewhere 1984. Is this realistic? Is it
possible somehow to get e.g. a news file for it (or for its (near)
successor)?

Of course I ask these only out of pure curiosity ;-)

Thanks,
P
