The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer. [1] The device was limited by the technology of the day. The ABC's priority is debated among historians of computer technology, because it was neither programmable , nor Turing-complete . [ 2 ]
In December 1939 John Atanasoff and Clifford Berry completed their experimental model to prove the concept of the Atanasoff–Berry computer (ABC) which began development in 1937. [40] This experimental model is binary, executed addition and subtraction in octal binary code and is the first binary digital electronic computing device.
Together, they created the Atanasoff-Berry computer, also known as the ABC which took five years to complete. [8] While the original ABC was dismantled and discarded in the 1940s, a tribute was made to the late inventors; a replica of the ABC was made in 1997, where it took a team of researchers and engineers four years and $350,000 to build.

With a grant of $650 received in September 1939 and the assistance of his graduate student Clifford Berry, the Atanasoff–Berry Computer (ABC) was prototyped by November of that year. According to Atanasoff, several operative principles of the ABC were conceived by him during the winter of 1938 after a drive to Rock Island, Illinois.
Public Domain. Henry Ford is known for many things — the most prominent being mass-manufactured cars and paying workers respectable wages. But his first automobile, made in 1896, was powered by ...
Atanasoff and Berry completed a special-purpose calculator for solving systems of simultaneous linear equations, later called the 'ABC' ('Atanasoff–Berry Computer'). This had 60 50-bit words of memory in the form of capacitors (with refresh circuits—the first regenerative memory) mounted on two revolving drums. The clock speed was 60 Hz ...
