   Hey, do you
have any VAXen over there?  How about getting an early
 Emacs running on those? 
 We have a VAX-11/780-5 (a 780 field upgraded to a 785) running VMS 
 
I'll let someone else do the VMS stuff.  DECUSLIB has a copy of GNU
Emacs 15, possibly the very first public release.
Some day, if a free time slot appears, I'd like to try to get the early
Unix Emacsen running in their natural Berkeley habitat.  I'd probably
run a VAX emulator for that.
   Or how about
TECO EMACS?  Only not on the PDP family you'd expect,
 but the 16-bit flavor. 
 Pete Siemsen wrote a new PDP-11 TECO [...] a couple of us suggested
 that he try adding the MIT TECO features to his program, and he said
 he'd give it a try. 
 
I was hinting a the very real EMACS-11 by Fred Fish.  Here's a
net.sources post from 1984, and a tarball from Pete Siemsen:

Again, I'd love to see this running, but I'm starved for time right now.
(Aren't we all?)
