Casio AI-1000 Pocket Lisp Computer from 1989

A demonstration of the Casio AI-1000, a 1989 pocket computer that runs Lisp, showing its REPL, functions, and macros.

This video is about the remarkable Casio AI-1000, a pocket computer from 1989 that supported the Lisp programming language. In this video I walk through its basic usage, using the Lisp REPL, defining Lisp functions, functions that return functions and macros.
