Good catch; I didn't know of that document. There is a later, more extensive
document (set) about it, "A Network Unix System for the ARPANET", but that's
from several years later, and doesn't include anything about the history of
the implementation.

The RFC says this (translated to lower case since the all-upper made my
eyes hurt :-):

  FOr further information concerning the different I/O calls the reader is
  directed to The Unix Programmer's Manual, Fifth Edition, K. Thompson,
  D. M. Ritchie, June 1974.

which I think makes it pretty definitive...
