From what I read in Dan Murphy's article "The beginnings of TECO", the 
early TECO implementation started out as a purely non-interactive tool -
he would punch the script with a Flexowriter and run it on the PDP-1 to 
fix up another tape. The reason was that the PDP-1 was in high demand at 
the time and you didn't want to occupy it's hardcopy terminal running the 
"Expensive Typewriter" for instance.
It also gained some kind of screen mode (CRT support) rather quickly, 
but it was stripped again when DEC included it in its distribution. Later 
DEC TECOs evolved it again.
From this time on ITS TECO (which was never stripped) and DEC TECO evolved 
in different directions.

I guess that the Twenex port ran on a regular DEC TECO, similar to 
TECO-11? At least the Standard TECO manual mentions TOPS-20 as well.
I would be interested to include this version of the Emacs macros in my 
family tree. So I would branch it off TECO-11.
