Lisp Machine Lisp is a dialect of the Lisp programming language
, a direct descendant of Maclisp
, and was initially developed in the mid to late 1970s as the systems programming language for the MIT
Lisp machine
s. Lisp Machine Lisp was also the Lisp dialect with the most influence on the design of Common Lisp
.
Lisp Machine Lisp itself branched into 3 dialects. Symbolics
named their variant ZetaLisp. Lisp Machines, Inc. and later Texas Instruments
(with the TI Explorer
) would share a common code base, but their dialect of Lisp Machine Lisp would differ from the version maintained at the MIT

and others.
The Lisp Machine Manual (also known as the Chinual) describes the Lisp Machine Lisp language in detail.
Some Lisp Machine Lisp features:
Lisp programming language
Lisp is a family of computer programming languages with a long history and a distinctive, fully parenthesized syntax. Originally specified in 1958, Lisp is the second-oldest high-level programming language in widespread use today; only Fortran is older...

Maclisp
MACLISP is a dialect of the Lisp programming language. It originated at MIT's Project MAC in the late 1960s and was based on Lisp 1.5. Richard Greenblatt was the main developer of the original codebase for the PDP-6; Jonl White was responsible for its later maintenance and development...

Some Lisp Machine Lisp features:
- it supports object-oriented programming with Flavors
- it has dynamic binding, but supports closures with a special construct
- integer numbers were read and printed in base 8 by default
