I still have the TOPS-20 user manuals sitting on my bookshelf! Now I'm showing my age. It is a pity that too often everyone equates new with good and old with outdated. I recently had a debate with a colleague who was upset when he found out the timetabling system we use is written lisp - his complaint was that it was no good because lisp was old. I pointed out that most of the 'inivations' being added to python, java and other 'modern' languages have been 'borrowed' from lisp (lambda, macros, etc). To get old and still be used and actively developed has to mean something!
