I have written a DOS based expert system shell that uses a windowing user
interface and is based on a standard backward chaining inference system.
It includes a structured rule editor, notepad editor, and on-line user
manual.  I have been using it to teach expert systems as part of an 
undergrad AI course at Western Oregon State College.  It has also been 
used at Oregon State ( Home Econ for Nutrition Expert Systems) and the
Univ. of Washington ( School of Education).

It is currently available in three forms: A public domain version limited
to 25 rules, A student version limited to 50 rules, and a Full version
( 300-500 rules depending on complexity).  I will be happy to send you a 
PD version of the program if you will email me your address.
