Yeah, but not for DEC PDP-11 TECO.
The MIT PDP-10 TECO and the macros that make it EMACS
are on the web at

Yeah, you could do that. I was never a big fan of
EMACS (aka
a later perjorative backronym: "Eight Megabytes and Continually Swapping".)
Ah, but Tim, that was early GNU emacs on underpowered Unix hosts. The memory
footprint of the original TECO implementation is much smaller:

plus pages for mapping the file into memory--maxes out around 260 pages.
(For the non-36-bit crowd, a Tops-20 page is 512 36-bit words, holding 2560
ASCII chars.)
