[COFF] ITS 138 listing from 1967

[Lars Brinkhoff]

For the benefit of Old Farts around here, I'd like to share the good
word that an ITS 138 listing from 1967 has been discovered.  A group of
volunteers is busy transcribing the photographed pages to text.

This version is basically what ITS first looked like when it went into
operation at the MIT AI lab.  It's deliciously arcane and primitive.
Mass storage is on four DECtape drives, no disk here.  Users stations
consist of five teletypes and four GE Datanet 760 CRT consoles (46
colums, 26 lines).  The number of system calls is a tiny subset of what
would be available later.

There are more listings from 1967-1969 for DDT, TECO, LISP, etc.  Since
they are fan-fold listings, scanning is a bit tricky, so a more labor-
intensive photographing method is used.
