Last IBM “Stretch” Computer Shut Down

September 5, 1980

The last IBM 7030 “Stretch” mainframe in active use is decommissioned at Brigham Young University. The first Stretch was delivered to Los Alamos National Laboratory in 1961, giving the model almost 20 years of operational service. The Stretch was famous for many things, but perhaps most notably it was the first IBM computer to use transistors instead of vacuum tubes, it was the first computer to be designed with the help of an earlier computer, and it was the world’s fastest computer from 1961 to 1964.
