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 407 rented from $800 to $920 per month ($10200 to $11800 per month in 2023 dollars), depending on the model. [3]Its print mechanism was used in the IBM 716 introduced in 1952 with the IBM 701 computer, and the 716 was used with many machines in the IBM 700/7000 series.

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 ...
