I don't know. I always thought it was kind of a nice idea. Doctors fer instance are so
stupid these days. They need all the help they can get. An expert system back in the 80s
w/o the level of collaboration we have possible today may not have been worth much. But
such a system that get's revised constantly, and would probably need AI for it to be
effective.
In any event, and I don't ever to this day recall doing a single search for it
anywhere, there's Knowledge Man on ebay right now. In Bulgaria. With 8" diaks!!
Only 285$!!! There's the possibility of a vintage item that's cooler then a PROLOG
compiler, on account of it's obscurity.
