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 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.
1976: The IBM 407 Accounting Machine was withdrawn from marketing. [66] 1978: IBM's Rochester plant made its last shipment of the IBM 082, 084, 085, 087, 514, and 548 machines.

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 ...
A time clock, sometimes known as a clock card machine, punch clock, or time recorder, is a device that records start and end times for hourly employees (or those on flexi-time) at a place of business.

IBM's electronic (vacuum tube) calculators could perform multiple calulations, including division. The card-programmed calculators used fields on punched cards not to specify the actual operations to be performed on data, but which "microprogram" hard-coded onto the plugboard of the IBM 604 or 605 calculator machine; a set of cards produced ...
