    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 ...

    A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...

    The following hub groupings were typical of later IBM machines: [7] Read brushes, 80 exit hubs, one for each card column. A tabulating machine might have two or three read stations, each with its own set of 80 hubs. A reproducing punch might have an additional read station after the punch station for verification.

    Note: IEBCOMPR is not a very flexible or user-friendly compare program. It can't restrict the comparison to only certain columns, it can't ignore differences in white space, it doesn't tell you where in the record the difference occurs, and it halts after 10 differences. On the other hand, it is fast, and it is present on all IBM mainframes.

    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 1418 is able to read a standard numerical font used by the IBM 407 in one of two sizes. [2] [5] It can also read vertical markings made with a pencil. IBM claimed it is suitable for cash-accounting applications where small payment stubs need to be processed. [30] It was developed and manufactured by IBM Endicott. [18] It has the ...
