Don's PDP-11 Pascal compiler
Well Don,
Google does know,
(perhaps surprising given the date), if only just barely:
"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."
