About the seminar

During the early days of Artificial Intelligence research, Lisp dialects were the primary programming language for developing symbolic (AI) applications. Multiple dialects were developed, but one of the most widely used was Interlisp, originated at BBN, and then moved to Xerox’s Palo Alto Research Center. By the early 1990s, symbolic AI research had waned and Interlisp had been overtaken by Common Lisp. Recently (2010), Interlisp.org, led by Larry Masinter, was formed by some of the original developers to modernize and enhance Medley Interlisp to run on modern machines. Today, Medley Interlisp is available on various Linux-based machines, on Apple Mac computers, and in several forms for Windows 10/11-based machines. This talk will discuss the history and technology of Medley Interlisp, its migration to and implementation on modern operating systems, some of the issues in modernising a historical software system, some key features, and future activities.
