In Pictures: If it ain't broke, don't fix it: ancient computers in use today
From 1970s minicomputers used for military programs (including nuclear weapons) to an IBM punch-card system still keeping the books at a Texas filter supplier, these are the computers that time forgot.
The U.S. Navy’s ship-based radar systems and Britain’s Atomic Weapons Establishment, which maintains that country’s nuclear warheads, use PDP minicomputers manufactured in the 1970s by Digital Equipment Corporation (DEC). Another user of the PDP is Airbus, the French jetliner manufacturer. The PDP was among the second wave of mainframes called minicomputers because they were only the size of a couple of refrigerators instead of big enough to fill a room.
