ABC: Atanasoff–Berry Computer

ABC is an abbreviation of Atanasoff–Berry Computer "ABC".

It was the first automatic electronic digital computer. The device has stayed to some extent difficult to understand, restricted by the technology of the day and implementation. The ABC's main concern is discussed and debated between historians of computer technology, for the reason that it was neither programmable, nor Turing-complete, not similar to the broadly well-known ENIAC machine of 1947 in division procured from it.


  • Envisioned in 1937, in the duration of 1939–42, the ABC was fabricated by Iowa State College mathematics and physics professor John Vincent Atanasoff with the assistance of graduate student Clifford Berry in the underground room of the physics building at Iowa State College .
  • In 1942, it was effectively examined, which created no more than to solve systems of linear equations. On the other hand, its transitional outcome storage method of system, a paper card writer/reader, was not made completely free from faults or defects, and when for World War II courseworks, John Vincent Atanasoff gone from Iowa State College; effort on the machine was broke off.
  • The ABC developed and initiated significant components of modern computing; consisting of binary arithmetic and electronic switching components, other than its special-purpose nature and be deficient of a unpredictable, stored program make a distinction of it from up to date current computers.
  • In 1990, the computer achieved an IEEE Milestone.
  • Up till it was found unexpectedly again in the 1960s, Atanasoff and Berry's computer work was not recognized around the world, in the midst of patent debates and quarrel above the first illustration of an electronic computer.
  • In those days, ENIAC that had been designed by John Mauchly and J. Presper Eckert, was regarded as to be the first computer in the present logic, other than in 1973 a U.S. District Court disproved the ENIAC patent and arrived at the conclusion that the ENIAC inventors had procured the subject issue of the electronic digital computer from Atanasoff.
  • While, in the mid-1970s, the confidentiality encompassing the British World War II expansion and growth of the Colossus computers that pre-dated ENIAC, was raised
    In June 1976, in Los Alamos, New Mexico, Colossus was illustrated at a conference and John Mauchly and Konrad Zuse were accounted to have been overwhelmed and surprised.
