  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.
