Probably at least half of all the Multics systems sold (I think the total was over 60) are still running. How about all the applications running on Lisp Machines? Symbolics and TI have sold thousands of them, so there must be a few "real applications" running on them. One I can think of offhand is that American Express is using an expert system running on Symbolics Lisp Machines to automate purchase authorization (I think it decides whether the current purchase is obviously consistent with your history, and if not it passes the decision on to a human). -- Barry Margolin, Thinking Machines Corp. barmar@think.com {uunet,harvard}!think!barmar
