MIT Museum: CADR - The LISP Machine (late 1970s)

The sign next to the base of the machine reads as follows (as near as I can tell, it's a bit fuzzy -- I've put guesses about the text in italics):

CADR - The LISP Machine

(late 1970s)

 

The LISP machine was the first hardware implementation of the AI programming language LISP. Researchers had long been frustrated by the constraints of running LISP programs on large mainframes. They developed LISP machines as stand alone, single user, high-performance computers that could run LISP programs faster and more efficiently. The first machines were hand assembled by Richard Greenblatt at the MIT AI Lab in the mid-1970s. This CADR machine was the basis of commercial products sold by two companies, LISP Machines, Inc founded by Richard Greenblatt, and Symbolics, founded by an ex-administrator of the AI Lab Russell Noftsker. The story of these two companies is typical. While successful in the mid-1980s, the advent of powerful microcomputers that could run LISP programs at similar speeds drove both companies into bankruptcy, LISP in 1987 and Symbolics in 1995.
