(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.
