Up till three or so years ago the VLA (Very Large Array radio telescope)
was using a PDP 11/70.  Most of the workstations were Sun Ultra 1 systems
that were horribly outdated to a point where I had already sent mine to
land fill a few years before.   Now they have a spiffy Linux cluster on
modern hardware, but the old system was as old as me.
