      IBM 701 EDPM
        Computer
               History of IBM
   IBM stands for International Business
    Machines, the largest computer company in the
    world today.
   The company incorporated in 1911, starting as a
    major producer of punch card tabulating
    machines.
   In the 1930s, IBM built a series of calculators
    (the 600s) based on their card processing
    equipment.
    IBM 701 EDPM Control Board
    The development of IBM's 701 EDPM in year
    1953.
   The 701's invention was part of the Korean War
    effort.
   Thomas Johnson Watson, Jr. wanted to
    contribute a "defense calculator" to aid in the
    United Nations' policing of Korea.
    Internal Operations & Memory
   Were built using vacuum tube technology
    which made use of special sealed tubes.
   Vacuum tubes operated at a very high
    temperature. They took from several seconds to
    several minutes to "warm up" to operating
    temperature.
   Mercury memory of the UNIVAC I and the
    electrostatic memory used in UNIVAC 1103
    and IBM 701.
         IBM "Type 701 EDPM"
      The IBM 701 was the first computer produced by
    IBM. Designed primarily for scientific calculations, the
    701 machine featured the IBM-invented tape drive
    vacuum column, an innovation which paved the way
    for magnetic tape to become a popular storage
    medium. The 700 series of machines, including the 704,
    709, and eventually the 7090 and 7094, dominated the
    large mainframe market for the next decade, and
    brought IBM from computer obscurity to first place in
    that same time period.
    A Programming Language Evolves
   The 701 also led to the development of the
    programming language FORTRAN.
    A year later, the first successful high level
    programming language was created. This was a
    programming language not written in 'assembly'
    or binary, which are considered very low level
    languages. FORTRAN was written so that more
    people could begin to program computers easily.
   The 700 series of machines, including the 704,
    709, and eventually the 7090 and 7094,
    dominated the large mainframe market for the
    next decade, and brought IBM from computer
    obscurity to first place in that same time period.
