Completely off topic - but nevertheless:  I had the pleasure to visit
Mt. John Observatory (of Canterbury Univ., New Zealand) yesterday and 
in one of the controll rooms I found this machine with a heat problem,
(unfortunately running SunOS instead of NetBSD), still in use:

Amazing sight, isn't it?
