63 Announced in August 1948, the Type 63 Card Controlled Tape Punch was able to read alphabetical and numerical information in IBM punched cards and perforate five-channel telegraphic tape with that data. (One roll of punched tape was the equivalent of approximately 1,500 cards.) The machine consisted of a card reading unit and a tape punching unit. The Type 63 was withdrawn from marketing in January 1972 -- after nearly a quarter-century in the IBM product line up.
650 [1] Announced as the IBM 650 Magnetic Drum Calculator in July 1953, the 650 became the most popular computer of the 1950s. It was operated by coded instructions stored on a magnetic drum, and was used to solve commercial or technical problems.
650 [2] The basic IBM 650 consisted of two units: IBM 650 Console Unit and IBM 655 Power Unit. Some of the 650's features as described in IBM publications of the time were:
650 [3] Magnetic Drum Memory -- 20,000 digit (2,000 word) or 10,000 digit (1,000 word); Stores data and instructions governing proper operation for each step in a procedure; Automatic table look-up; Console permits visible inspection of any machine location and altering of instructions; Discrepancies automatically detected and indicated on a visible panel through programming.
650 [4] The 650 was viewed as the foundation of a flexible and integrated "building block" data processing system. IBM machines could be added to the 650 to provide for punched card input-output, line printed output, magnetic tape input-output, high-speed magnetic core storage, indexing accumulators, and automatic floating-decimal arithmetic in various combinations.
650 [5] By the time the last IBM 650 was manufactured in 1962, nearly 2,000 of the machines had been delivered to customers -- the most of any electronic computer of that period.
6670 [1] IBM's Office Products Division introduced the 6670 Information Distributor in February 1979 as a versatile office information distributor that printed with a laser and received and transmitted documents electronically over ordinary telephone lines. The 6670 also linked word processing and data processing, printing computer-based information in typewriter-like quality originals using customized formats.
6670 [2] It could print multiple sets of documents at speeds of up to 1,800 characters per second and could also function as a high-quality copier. The 6670 was withdrawn from marketing in August 1986.
