WAITS
       Westcoast Alternative to ITS

WAITS
 /wayts/, n.

    The mutant cousin of TOPS-10 used on a handful of systems at SAIL up to
    1990. There was never an ?official? expansion of WAITS (the name itself
    having been arrived at by a rather sideways process), but it was frequently
    glossed as ?West-coast Alternative to ITS?. Though WAITS was less visible
    than ITS, there was frequent exchange of people and ideas between the two
    communities, and innovations pioneered at WAITS exerted enormous indirect
    influence. The early screen modes of EMACS, for example, were directly
    inspired by WAITS's ?E? editor ? one of a family of editors that were the
    first to do ?real-time editing?, in which the editing commands were
    invisible and where one typed text at the point of insertion/overwriting.
    The modern style of multi-region windowing is said to have originated
    there, and WAITS alumni at XEROX PARC and elsewhere played major roles in
    the developments that led to the XEROX Star, the Macintosh, and the Sun
    workstations. Also invented there were bucky bits ? thus, the ALT key on
    every IBM PC is a WAITS legacy. One WAITS feature very notable in pre-Web
    days was a news-wire interface that allowed WAITS hackers to read, store,
    and filter AP and UPI dispatches from their terminals; the system also
    featured a still-unusual level of support for what is now called multimedia
    computing, allowing analog audio and video signals to be switched to
    programming terminals.

WAITS

   /wayts/ The mutant cousin of TOPS-10 used on a handful of
   systems at SAIL up to 1990.  There was never an "official"
   expansion of WAITS (the name itself having been arrived at by
   a rather sideways process), but it was frequently glossed as
   "West-coast Alternative to ITS".  Though WAITS was less
   visible than ITS, there was frequent exchange of people and
   ideas between the two communities, and innovations pioneered
   at WAITS exerted enormous indirect influence.  The early
   screen modes of Emacs, for example, were directly inspired

   Ken Shoemake adds:

   Some administrative body told us we needed a name for the
   operating system, and that "SAIL" wouldn't do.  (Up to that
   point I don't think it had an official name.)  So the anarchic
   denizens of the lab proposed names and voted on them.
   Although I worked on the OS used by CCRMA folks (a parasitic
   subgroup), I was not writing WAITS code.  Those who were,
   proposed "SAINTS", for (I think) Stanford AI New Time-sharing
   System.  Thinking of ITS, and AI, and the result of many
   people using one machine, I proposed the name WAITS.  Since I
   invented it, I can tell you without fear of contradiction that
   it had no official meaning.  Nevertheless, the lab voted that
   as their favorite; upon which the disgruntled system
   programmers declared it the "Worst Acronym Invented for a
   Time-sharing System"!  But it was in keeping with the creative
   approach to acronyms extant at the time, including
   self-referential ones.  For me it was fun, if a little
   unsettling, to have an "acronym" that wasn't.  I have no idea
   what the voters thought. :)
