Functional schematic showing the Williams tubes in green. Tube C holds the current instruction and its address; A is the accumulator; M is used to hold the multiplicand and the multiplier for a multiply operation; and B contains the index registers, used to modify instructions.
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]
The IBM 701 Electronic Data Processing Machine, known as the Defense Calculator while in development, was IBM’s first commercial scientific computer and its first series production mainframe computer, which was announced to the public on May 21, 1952. [1]

Replica of the Atanasoff–Berry computer at Iowa State University The 1946 ENIAC computer used more than 17,000 vacuum tubes. A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry.
The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable, fully automatic digital computer. [3]
