The Revised Maclisp Manual (The Pitmanual): "Internet, December 16, 2007—The Revised Maclisp Manual, originally published in hardcopy at MIT in 1983 as the Saturday Evening Edition, is now available on the web as the Sunday Morning Edition.
Nicknamed The Pitmanual, The Revised Maclisp Manual describes the programming language MACLISP, which ran on the DEC PDP-10 and Honeywell 6180/6880. This newly-updated Sunday Morning Edition features many editorial corrections, an enhanced hypertext index, and a Common Lisp Conversion guide that offers advice on upgrading old MACLISP programs to run in Common Lisp."
