Exploring PDP-1 Lisp (1960)

Lisp was developed in 1958 by John McCarthy at MIT as a high-level symbolic programming language for AI research, and was first implemented on the DEC PDP-1 computer in 1960 by 14-year-old Peter Deutsch. Deutsch's implementation pioneered the read-eval-print loop (REPL), creating the first interactive programming environment and transforming Lisp from a theoretical punch-card language into a practical, interactive tool. This resource provides hands-on instructions for programming in PDP-1 Lisp, intended for beginners with or without prior Lisp knowledge.
