Sorry but it just seemed to me that you could get more coders creating your own Topic, picked up by the last five or so words in your post at that time. Also saying this will probably shock you but...Canoma? (Checked it, came out a year after I was born.) Symbolics?
(The computer manufacturer right? Thanks Wikipedia.) You are talking about those right? If your talking about symolics system their operating system is still maintained. Heh, sorry for the 'scrabbled' post.
