A punched card sorter is a machine for sorting decks of punched cards. Sorting was a major activity in most facilities that processed data on punched cards using unit record equipment. The work flow of many processes required decks of cards to be put into some specific order as determined by the data punched in the cards.
Because punched card readers scan uniform rectangular holes in a precise arrangement, any damage to the physical card makes it unusable. In the 1950s and 1960s, when the use of punch cards became widespread, manufacturers printed a warning on each card reading "Do not fold, spindle or mutilate".
Fursuit making is a growing industry, with new costume makers who handcraft custom suits entering the market every week. [5] A few dozen of these makers are highly respected and command prices up to $4,500 or more for a full suit, [ 2 ] while there are several hundred more who charge less, usually between $600 and $1,000.
An IBM 80-column punched card of the type most widely used in the 20th century IBM 1442 card reader/punch for 80 column cards. A computer punched card reader or just computer card reader is a computer input device used to read computer programs in either source or executable form and data from punched cards.
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 ...
Edge-notched cards were used for course scheduling in some high schools and colleges. [11] Keysort cards were also used in World War II codebreaking. The Stasi used edge-notched cards (German: Kerblochkarteikarten) from 1965 to index information including details of staff, crimes, people under surveillance, and vehicles. Cards often stored ...
Aperture cards created from 35mm roll film mounted on to blank cards have to be treated with great care. Bending the card can cause the film to detach and excessive pressure to a stack of cards can cause the mounting glue to ooze creating clumps of cards which will feed through duplicators and other machinery either poorly or not at all.
Cards were typically available in buff (sort of an off beige natural color), red, green and blue. There were thousands of different card types, each with its own stock number. Large organizations, such as universities, would have cards with their logo in the background. Other punch card suppliers often used the IBM part numbers.
