I feel that I have to point out that the version of TECO in which EMACS was
first implemented is completely and entirely incompatible with the VAX, Alpha,
or Itanium, given that it was written for PDP-10 systems running the ITS
operating system at the MIT AI Lab, and ported to TOPS-20 from there.  It was
never ported even to Tops-10, since it assumes a paged memory model which the
older DEC OS for the PDP-6/PDP-10 lacked.

It is remarkably full of architectural assumptions (36 bits/word, characters as
7-bit ASCII packed 5/word, etc. usw. k.t.l. ad nauseam.)

Old .sig (1993-2003):

Still the last person to do development and maintenance on the 2 programs...
