Maclisp is a dialect of the Lisp programming language . Maclisp was developed in 1966 at MIT as part of Project MAC . There were implementations for the PDP-6 and PDP-10 computers and for the Multics operating system .
Maclisp was the basis of many other Lisp dialects (for example ZetaLisp , S-1 Lisp ). The resulting language variants were incompatible with each other, which is why a common specification for a successor to Maclisp (and its variants) was created in 1981. The result of this work is the Lisp dialect Common Lisp , the ANSI standard of which was published in 1994.
Well-known programs that were originally written in Maclisp were the Macsyma computer algebra system , an implementation of the Emacs editor called Multics Emacs, and the SHRDLU language analysis program .
