LISP machine
From Computer History Wiki
LISP machines were a series of custom microcoded workstations intended to run large LISP programs. The first two generations (the sole prototype, the CONS machine; and the later somewhat volume CADR) were built at MIT, and direct descendants of these were produced and sold by Symbolics and LISP Machines Inc; others were produced by other vendors, such as Texas Instruments and Xerox.
