What Happened on May 27th

After almost a decade of service, MIT shut down its Whirlwind computer. The machine debuted on Edward R. Murrow's See It Now television series in 1951, showing off its quick speed and large memory compared to other systems at the time. Project director Jay Forrester described the computer as a "reliable operating system," running 35 hours a week at 90-percent utility using an electrostatic tube memory.
