The IBM 650 Magnetic Drum Data-Processing Machine is one of IBM's early computers, and the world’s first mass-produced computer. It was announced in 1953 and in 1956 enhanced as the IBM 650 RAMAC with the addition of up to four disk storage units. Almost 2,000 systems were produced, the last in 1962. Support for the 650 and its component units was withdrawn in 1969.
