Cybernetic Physician v1.00D: an artificial intelligence expert system with inference engine and medical knowledge base. Intended for home use, and using non-technical terms, this program attempts to diagnose illness and injury by analyzing the user's responses to simple "yes/no" questions. This program is not intended to replace the services of a qualified physician. This is a full working, freely distributable shareware evaluation version with a small, but useful, subset of the entire knowledge base.
