The IBM 650 Magnetic Drum Data-Processing Machine is an early digital computer produced by IBM in the mid-1950s. [2][3] It was the first mass-produced computer in the world. [4][5] Almost 2,000 systems were produced, the last in 1962, [6][7] and it was the first computer to make a meaningful profit. [7]
Announced in 1953, the IBM 650 Magnetic Drum Data Processing Machine was the world’s first mass-produced computer — and the first computer to generate a significant profit. Originally geared toward IBM’s scientific and engineering clientele, it is nevertheless also widely considered to be the first commercial business computer, and it ...
Sep 4, 2023 · The 650 was a true general-purpose computer, the natural evolution of the CPC (Card Programmed Calculator) to a stored-program computer with a full set of decimal arithmetic, logical, and control instructions, plus (later) the ability to handle alphabetic data.
The IBM 650, delivered at the end of 1954 for colleges and businesses, was a decimal implementation of the IAS design. With this low-cost magnetic drum computer, which sold for about \$200,000 apiece (compared with about \$1,000,000 for the scientific model, the IBM 701), IBM had….
Introduced in 1954, the 650 read data from punch cards and magnetic tapes. By the end of the 1950s, there were more than 1,500 units installed, making it the most widely used computer in...
The IBM 650 computer system was called a data processing machine rather than a computer. In 1953 IBM Endicott, New York, announced the IBM 650 Magnetic Drum Data Processing Machine. This was the first mass-produced computer. Between 1953 and 1962 almost 2000 systems were produced.
The IBM 650 (photo) was one of IBM’s early computers, and the world’s first mass-produced (photo) computer. It was announced in 1953, and over 2000 systems were produced between the first shipment in 1954 and its final manufacture in 1962.
