Lisp Machine Lisp

Lisp Machine Lisp branched into three 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 AI Lab by Richard Stallman and others.

Manual

The Lisp Machine Manual describes the Lisp Machine Lisp language in detail. The manual was popularly termed the Chine Nual, because the full title was printed across the front and back covers such that only those letters appeared on the front. This name is sometimes further abbreviated by blending the two words into Chinual.
