The HRSTS version of it can be found in the UNSW tapes.
The usenix 77 tape has h/help/teco and a 0-sized h/teco/cont.a
Matt Fichtenbaum's TECO for Ultrix appears in

"Harvard UNIX TECO runs under the UNIX operating system on a
PDP-11.  It was written by Bob Case, Peter Langston, Bruce Borden,
Brent Byer, and Tucker Taft using the Harvard-Radcliffe Student
Timesharing System (HRSTS)."

"Harvard UNIX TECO is based on a 1973 version of MIT TECO and is
written in MACRO-11. There is a possibility that this TECO will
be expanded and recoded into C in the near future."


"HRSTS (new)Teco V_3p"



"BBN has a TECO for Unix."
