Computers at -50y:
(from http://www.computerhope.com/history/194060.htm )
1955 The ENIAC is turned off for the last time. Itâ??s
estimated to have done more arithmetic than the
entire human race had done prior to 1945.
1956 On September 13, 1956 the IBMâ??s 305 RAMAC is
the first computer to be shipped with a hard disk
drive that contained 50 24-inch platters and was
capable of storing 5MB of data.
1957 IBM announces it will no longer be using vacuum
tubes and releases its first computer that had
2000 transistors.
1957 Fairchild Semiconductor is founded by Andy Grove,
Eugene Kleiner, Gordon Moore, Jerry Sanders, Robert Noyce.
1957 Digital Equipment Corporation is founded by Kenneth
Olsen. The company will later become a major
network computer manufacturer. (And die horribly somewhere
in the bowels of HP/Compaq -- ed.)
1957 Russia launches the first artificial satellite,
named Sputnik on October 4, 1957.
1957 In response to Sputnik the United States creates
the new agency ARPA.
1957 Casio is established.
1958 The National Advisory Committee for Aeronautics is
renamed to National Aeronautics and Space
Administration (NASA).
1958 NEC builds its first computer the NEAC 1101.
1958 William Higinbotham created the first video game
called: Tennis for Two.
