Opus

   <project, product> A {Honeywell} {operating system} promised
   as a sop to customers after canning {Multics} in 1985.  Opus
   was to provide everything Multics had and more, plus total
   compatibility with the {Level 6}/{DPS6} operating system.

   "Opus" was a code name, the system was officially named VS3
   (short for HVS R3 or Honeywell Virtual System Release Three).
   It was to run on the {DPS6-plus} hardware known internally as
   the MRX and HRX, and be all things to all people.

   The hardware was a dud (though it did run the native DPS6
   software just fine), and the goal was, shall we say,
   ambitious.  The effort was cancelled by {Bull} in 1987, in
   favor of another project going on in France.
