COMPUTER

IBM 653

IBM 650

<computer> A computer, produced ca. 1955 and in use in the late 1950s, with rotating magnetic drum storage and {punched card} input. Its memory words could store 10-digit decimal numbers and each instruction had two addresses, one for the operand and one for address of the next instruction on the drum. SOAP was its (optimising) assembler. Languages used on it included BACAIC, BALITAC, BELL, CASE SOAP III, {DRUCO I}, EASE II, ELI, ESCAPE, FAST, FLAIR, FORTRANSIT, FORTRUNCIBLE, GAT, IPL, Internal Translator, KISS, MITILAC, MYSTIC, OMNICODE, PIT, RELATIVE, RUNCIBLE, SIR, SOAP, Speedcoding, SPIT, SPUR.

IBM 650

The IBM 650 Magnetic Drum Data-Processing Machine is an early digital computer produced by IBM in the mid-1950s. It was the first mass produced computer in the world. Almost 2,000 systems were produced, the last in 1962, and it was the first computer to make a meaningful profit. The first one was installed in late 1954 and it was the most-popular computer of the 1950s.

The 650 was marketed to business, scientific and engineering users as a general-purpose version of the IBM 701 and IBM 702 computers which were for scientific and business purposes respectively. It was also marketed to users of punched card machines who were upgrading from calculating punches, such as the IBM 604, to computers.^: 5

Because of its relatively low cost and ease of programming, the 650 was used to pioneer a wide variety of applications, from modeling submarine crew performance to teaching high school and college students computer programming. The IBM 650 became highly popular in universities, where a generation of students first learned programming.

It was announced in 1953 and in 1956 enhanced as the IBM 650 RAMAC with the addition of up to four disk storage units. Support for the 650 and its component units was withdrawn in 1969.

The 650 was a two-address, bi-quinary coded decimal computer (both data and addresses were decimal), with memory on a rotating magnetic drum. Character support was provided by the input/output units converting punched card alphabetical and special character encodings to/from a two-digit decimal code.
