Maclisp

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. 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. The name 'Maclisp' started being used in the early 1970s to distinguish it from other forks of PDP-6 Lisp, notably BBN Lisp. Maclisp ran on DEC PDP-6/10 computers, initially only on ITS, but later under all the other PDP-10 operating systems. Its original implementation was in PDP-10 assembly language. It was later implemented on Multics using PL/I. Maclisp developed considerably in its lifetime, adding major features along the way which in other language systems would typically correspond to major release numbers.
