The 402 could read punched cards at a speed of 80 to 150 cards per minute, depending on process options, while printing data at a speed of up to 100 lines per minute. The built-in line printer used 43 alpha-numerical type bars (left-side) and 45 numerical type bars (right-side, shorter bars) to print a total of 88 positions across a line of a report.

The IBM Card-Programmed Electronic Calculator or CPC was announced by IBM in May 1949. Later that year an improved machine, the CPC-II , was also announced. IBM's electronic (vacuum tube) calculators could perform multiple calulations, including division.
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 608 plugboard programmable calculator was IBM's first all-transistor product, released in 1957; this was a console type system, with input and output on punched cards, and replaced the earlier, larger, vacuum-tube IBM 603. Early calculator light-emitting diode (LED) display from the 1970s
An IBM tabulating machine, such as the 402 or 407 series would have several counters available in different sizes. (For example, the IBM 402/403 had four sets each of 2, 4, 6 and 8 digit counters, labeled 2A, 2B, 2C, 2D, 4A, 4B etc.) Each counter had two counter control entries to specify either addition (plus) or subtraction (minus). If ...
The Commercial Processing Workload (CPW) is a simplified variant of the industry-wide TPC-C benchmarking standard originally developed by IBM to compare the performance of their various AS/400 (now IBM i) server offerings.
[9] [10] The IBM 402 series, introduced after World War II, had a similar print arrangement and was used by IBM in early computing devices, including the IBM Card-Programmed Electronic Calculator. [11] IBM's first commercial computer, the IBM 701, introduced in 1952, used a line printer, the IBM 716, that was based on the type wheel IBM 407 ...
