IBM 407 (left) with IBM 519 (on right). The 407 read punched cards, totaled fields on the cards, made simple decisions, printed results, and, with the aid of a summary punch, output results on punched cards that could be input to other processing steps. The operation of the 407 was directed by the use of a removable control panel and a carriage ...
IBM 402 and 403, from 1948, were modernized successors to the 405. Control panel for an IBM 402 Accounting Machine. The 1952 Bull Gamma 3 could be attached to this tabulator or to a card read/punch. [20] [21] IBM 407. Introduced in 1949, the 407 was the mainstay of the IBM unit record product line for almost three decades.
The IBM 046 Tape-to-Card Punch and the IBM 047 Tape-to-Card Printing Punch (which was almost identical, but with the addition of a printing mechanism) read data from punched paper tape and punched that data into cards. The IBM 063 Card-Controlled Tape Punch read punched cards, punching that data into paper tape. [83]
The IBM 80-column punched card format dominated the industry, becoming known as just IBM cards, even though other companies made cards and equipment to process them. [65] A 5081 card from a non-IBM manufacturer. One of the most common punched card formats is the IBM 5081 card format, a general purpose layout with no field divisions.
The 407 also had exits from each print wheel that could then feed the counters for addition or subtraction. This insured that totals always matched what was printed. Counter entries. An IBM tabulating machine, such as the 402 or 407 series would have several counters available in different sizes.
The IBM 2956 Models 2 and 3 are custom build optical mark/hole readers designed to be attached to an IBM 2740 Communications Terminal. [11] The IBM 2956-2 can read cards that have either been hand or machine marked or that have been punched. The cards can be fed by hand or from the 400 card hopper. It has a 400 card stacker. [11]
Products, services, and subsidiaries have been offered from International Business Machines (IBM) Corporation and its predecessor corporations since the 1890s. [1] This list comprises those offerings and is eclectic; it includes, for example, the AN/FSQ-7, which was not a product in the sense of offered for sale, but was a product in the sense of manufactured—produced by the labor of IBM.
In 1937, Frank Carrell, working for IBM applied for a patent on a ballot marking device that recorded on standard punched cards. This was incorporated into a full-sized voting booth with voter interface that resembled a mechanical voting machine, but recording on ballot cards that could be tabulated on standard punched-card tabulating machines.
