TOPS-10

( /tops·ten/, n.)

   {DEC}'s  proprietary  OS  for  the  fabled  {PDP-10} machines, long a
   favorite  of  hackers  but  now  long  extinct.  A fountain of hacker
   folklore; see Appendix A. See also {ITS}, {TOPS-20}, {TWENEX}, {VMS},
   {operating  system}.  TOPS-10  was  sometimes  called  BOTS-10  (from
   `bottoms-ten') as a comment on the inappropriateness of describing it
   as the top of anything.
