The 1442 Model 5 is a card punch only and is considered the companion unit to the 2501 to provide a separate card path for card input and output. However, a model 6 or 7 may be installed with the 2501 in place of a model 5; in this case the 2501 should be considered the primary input unit.

Punched card input/output. A computer punched card reader or just computer card reader is a computer input device used to read executable computer programs and data from punched cards under computer control. A computer card punch is a computer output device that punches holes in cards under computer control. Sometimes computer card readers were combined with computer card punches and, later, other devices to form multifunction machines.

Some of the stacks of cards, as. well as the boxes, had seemingly random. collection of different colored cards. All had. names, usually cryptic, written on the sides of. the cards with a felt-tipped pen.

Programming with Punched Cards. © 2005 Dale Fisk. All rights reserved. dalefisk@gmail.com. It must have been about 1973. Life at IBM was good, and I was busy doing whatever it. is that engineers did then. Suddenly, in the life of our project, something came up that. called for a computer program that did not exist, and I was asked to create it.

The 1442 is a single unit that processes cards serially, column by column, from a single supply hopper. All cards first pass the read station (model 6 and 7), then the punch station. This permits each card to be read, punched, or read and punched.

The card motion and punching process continues until the punch data word contains a one in the 12-bit position (punch data is in bits 0-11). When this end-punch bit is detected, that column is punched and the card is moved to the next column. An operation complete interrupt is given.

Figure 1 Punched card program decks. I learned that each punched card described one instruction in the program and that each. box could hold about two thousand cards. The size of a box, then, became a built-in limit. - 2 -. to the size of a program.
