If I remember the PS300 right, the best/most novel part (to me) was 
the function network concept for handling user input. There are hints of
similar concepts nowadays in some of the UIMS toolboxes, but it's been a 
long dry spell between then and now. Congrats to you and to E&S on 
building a good interesting machine. 

(Thanks for responding - this is getting interesting!)
