bitty box
     
         (Or "calculator") /bit'ee boks/ A computer
        sufficiently small, primitive, or incapable as to cause a
        hacker acute claustrophobia at the thought of developing
        software on or for it.  The term is especially used of small,
        obsolescent, {single-tasking}-only {personal computers} such
        as the {Atari 800}, {Osborne}, {Sinclair}, {VIC-20}, {TRS-80}
        or {IBM PC}, but the term is a general pejorative opposite of
        "real computer" (see {Get a real computer!}).
     
        See also {mess-dos}, {toaster}, {toy}.
