It was later used with other computers of the IBM 1400 series and IBM 7000 series product lines. It was adapted as the IBM 1622 Card Read-Punch for the IBM 1620 and provided the basic design for the models 2501, 2520 and 2540 equipment used with the IBM … It was later used with other computers of the IBM 1400 series and IBM 7000 series product lines. It was adapted as the IBM 1622 Card Read-Punch for the IBM 1620 and provided the basic design for the models 2501, 2520 and 2540 equipment used with the IBM … By combining the higher speed IBM 2501 card reader and a punch-only IBM 1442, the 1442's limitations are overcome: faster input; the 2501 is buffered and therefore will not overrun if the channel is too busy with other devices to give it attention whenever a column has been read.

IBM 2501 Card Reader. The IBM 2501 Card Reader , Model A1 and Model A2, provides card input for the IBM 1130 Computing System. Card reading is under direct program control. Functional Description.

One Rochester 2540 is installed with the first IBM System/360 Model 40 shipped to a customer (NASA at Cape Kennedy, Fla.).

A card reader such as the IBM 3505 is an electronically mechanized input device used to read punched cards. Sometimes combined with card punches and other functions to form multifunction machines, such as the IBM 2540 card reader-punch, such devices were attached to a computer.

The 2540 could read punched-cards at 1000 cards per minute (CPM) and punch at 300 CPM. 2021-03-28 · The IBM 2540 Reader Punch Photo: Introduction to IBM Data Processing Systems , IBM Textbook C20-1684, 1968.
