  Lisp Machine
       
          1.  Any machine (whether notional or actual)
          whose instruction set is Lisp.
       
          2.  A line of workstations made
          by Symbolics, Inc. from the mid-1970s (having grown out of
          the MIT AI Lab) to late 1980s.  All system code for
          Symbolics Lisp Machines was written in Lisp Machine Lisp.
          Symbolics Lisp Machines were also notable for having had
          space-cadet keyboards.
