blue box n. 1. obs. once upon a time, before all-digital switches made
   it possible for the phone companies to move them out of band, one could
   actually hear the switching tones used to route long-distance calls.
   early phreakers built devices called `blue boxes' that could reproduce
   these tones, which could be used to commandeer portions of the phone
   network. this was not as hard as it may sound; one early phreak
   acquired the sobriquet `captain crunch' after he proved that he could
   generate switching tones with a plastic whistle pulled out of a box of
   captain crunch cereal there were other colors of box with more
   specialized phreaking uses; red boxes, black boxes, silver boxes, etc.
   there were boxes of other colors

   but the blue box was the original and archetype. 2. n. an ibm machine,
   especially a large non-pc one.

        run-time environment on the more modern rhapsody operating

        the current version of mac os and will thus incorporate future
        mac os improvements.
