This article details the rediscovery of the source code for AM and EURISKO, two groundbreaking AI programs created by Douglas Lenat in the 1970s and early 80s. AM autonomously rediscovered mathematical concepts, while EURISKO excelled in VLSI design and even defeated human players in the Traveller RPG. Lenat had previously stated he no longer possessed the code, but it was found archived on SAILDART, the original Stanford AI Laboratory backup data, and in printouts at the Computer History Museum. The code was password protected until Lenat's passing, and has now been made available on Github.
An article detailing the history of LISP machines and the SCHEME-78 microprocessor, designed to closely match the LISP language, developed by Guy L. Steele and Gerald Jay Sussman. It discusses the motivations behind creating dedicated LISP hardware, its eventual decline, and its relevance to modern AI hardware.
