- Q522906 abstract "The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer, an early electronic digital computing device that has remained somewhat obscure. The ABC's priority is debated among historians of computer technology, because it was not programmable, nor Turing-complete. Many credit John Mauchly and J. Presper Eckert, creators of the ENIAC, which came into use in July 1946, with the title. Others cite the programmable British Colossus computer which was demonstrated to be working on December 8, 1943. Some historians argue that the credit undisputedly belongs to Iowa State mathematics and physics professor John Vincent Atanasoff for his work with the ABC, with the help of graduate student Clifford Berry. Conceived in 1937, the machine was not programmable, being designed only to solve systems of linear equations. It was successfully tested in 1942. However, its intermediate result storage mechanism, a paper card writer/reader, was unreliable, and when John Vincent Atanasoff left Iowa State College for World War II assignments, work on the machine was discontinued. The ABC pioneered important elements of modern computing, including binary arithmetic and electronic switching elements, but its special-purpose nature and lack of a changeable, stored program distinguish it from modern computers. The computer was designated an IEEE Milestone in 1990.Atanasoff and Berry's computer work was not widely known until it was rediscovered in the 1960s, amidst conflicting claims about the first instance of an electronic computer. At that time, the ENIAC was considered to be the first computer in the modern sense, but in 1973 a U.S. District Court invalidated the ENIAC patent and concluded that the ENIAC inventors had derived the subject matter of the electronic digital computer from Atanasoff (see Patent dispute).".
