I think just
about every DEC computer had a version of TECO, right?
I don't recall seeing
it on our PDP-8 and -12. Does anybody else?
I found this:
"TECO, the text editor, was included in the standard OS/8
distributions and is a general purpose language (the Emacs editor
began as a set of TECO macros!). The story of TECO on the PDP-8 is
convoluted. Russ Hamm implemented TECO under his OS8 (without a
slash) system, and then gave a listing to Don Baccus at the Oregon
Museum of Science and Industry (OMSI) who, along with Barry Smith
ported it to PS/8. This was the beginning of what became Oregon
Software, later famous for OMSI Pascal.
Richard F. Lary and Stan Rabinowitz made OS/8 TECO more compatible
with other versions of TECO, and the result of this work is the
version distributed by DECUS (catalog number 110450 is the
manual). RT-11 TECO for the PDP-11 is a port of this code."
