To most enthusiasts, Arctic is best known for their Freezer line of CPU coolers as well as their thermal compound called MX-2 and MX-4. [2] The Freezer line of coolers is available in different fan speed, cooling capacity and motherboard compatibility [3] to cater the needs of different type of users from HTPC users to enthusiasts and overclockers.
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 computer card punch is a computer output device that punches holes in cards. Sometimes computer punch card readers were combined with computer card punches and ...
A punched card (also punch card [1] or punched-card [2]) is a piece of card stock that stores digital data using punched holes. Punched cards were once common in data processing and the control of automated 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 ...
IBM 080 Card Sorter IBM 082 Card Sorter. 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 ...
The cycles were divided into points according to when the rows on a punched card would appear under a read or punch station. On most [6] machines, cards were fed face down, 9-edge (bottom edge) first. Thus the first point in a card cycle would 9-time, the second 8 time and so on to 0-time. The times from 9 to 0 were known as digits.
The first combination of card punch and typewriter, permitting selected text to be typed and punched, was developed by the Powers company in 1925. [23] The IBM 824 Typewriter Card Punch was an IBM 024 where the 024 keyboard was replaced by an IBM electric typewriter. [24] Similarly, the IBM 826 used an IBM 026 Keypunch. [25]
This part number was likely for a standard punch card, with the stock printing across all 80 columns. Not certain, but I would expect a different number for other styles of printing (or possibly if the corner was cut on the other end). Standard Form 5081 was a US Government Standard Form that adopted the IBM 5081 punch card standard.
