Back in an earlier day (mid-80s I think), the Washington DC VAXLUG did a
VMS version poll at the start of each meeting. There was always one guy in
the front who would raise his hand for VMS 1. The facilitator would laugh
and say, "It runs the reactor, right?"  Of course, being the DC area,
nobody knew for sure if that was really true, or some other application. :-)
