Adding the ELIZA program to the list.

My first experience with this program was at a Terminal in the American Museum of Science and Energy Oak Ridge TN.

ELIZA is an early natural language processing program
created around 1964 by Joseph Wiezenbaum at MIT.  This
version is adapted from ELIZA.BAS which appeared in
Creative Computing magazine in 1977, written by Jeff
Shrager and adapted for IBM PC in the early 1980's by
Patricia Danielson and Paul Hashfield.

ELIZA simulates a psychotherapist interacting with a
human patient. Enter "shut up" to stop the dialog.
