Richard Greenblatt was primary author of [[Mac Hack]] (The Greenblatt Chess Program) in 1966 and [[Timeline#1967|1967]], and along with [https://en.wikipedia.org/wiki/Tom_Knight_%28scientist%29 [Mathematician#TKnight|Tom Knight]] main designer of the [https://en.wikipedia.org/wiki/Lisp_machine MIT Lisp machine]. In 1978 Mac Hack got adapted to the Chess-orientated Processing System [[CHEOPS]], one of the first dedicated hardware approaches in computer chess.

In 1979, Greenblatt founded [https://en.wikipedia.org/wiki/Lisp_Machines Lisp Machines, Inc.] to build and sell [https://en.wikipedia.org/wiki/Lisp_Machines Lisp machines], competing with [https://en.wikipedia.org/wiki/Symbolics Symbolics], a company founded by his former [https://en.wikipedia.org/wiki/AI_Lab MIT AI Lab] fellows around [https://en.wikipedia.org/wiki/Russell_Noftsker Russell Noftsker], [https://en.wikipedia.org/wiki/Tom_Knight_%28scientist%29 [Mathematician#TKnight|Tom Knight]] and [[Jack Holloway]]. Lisp Machines, Inc. went bankrupt in 1987.
