The IBM 2540 is a punched-card computer peripheral manufactured by IBM Corporation for use of System/360 and later computer systems. The 2540 was designed by IBM's Data Processing Division in Rochester, Minnesota, and was introduced in 1965. The 2540 could read punched-cards at 1000 cards per minute (CPM) and punch at 300 CPM.

Rochester develops the IBM 2540 card reader/punch. One Rochester 2540 is installed with the first IBM System/360 Model 40 shipped to a customer (NASA at Cape Kennedy, Fla.). The Centrex telephone system is installed.

The classic example of early CU integration was the 2701 communications controller and the integrated CTC adapters. Disk, tape, and unit record devices of the same era had discrete controllers. Unit record CU (2821) was interesting in that it talked to devices that did different things: 1403/1404 printer and 2540 card reader-punch. Clever of them.

The IBM 2540 Reader Punch The IBM 2540 card reader (right) and punch (left), 1965. IBM 2540 reader/punch derived from the 1402 that was introduced with System 360 IBM 2560 Multi-Function Card Machine (MFCM), first introduced for the IBM System/360 Model 20, could also collate, sort and print/interpret. IBM 3505 reader and its companion 3525 reader/printer/punch that was introduced for the System/370 in 1971.

The card reader (CR) function accepts input from the following locally attached devices: IBM® 2501 Card Reader, IBM 2540 Card Reader Punch, IBM 3505 Card Reader, and IBM 3525 Card Punch with the read feature.

1965 Punch error correction on the IBM 2540 Card Read Punch is not performed. The IBM 3525 Card Punch accepts only format-F records for print and associated data sets.

The classic example of early CU integration was the 2701 communications controller and the integrated CTC adapters. Disk, tape, and unit record devices of the same era had discrete controllers. Unit record CU (2821) was interesting in that it talked to devices that did different things: 1403/1404 printer and 2540 card reader-punch. Clever of them. Many IBM peripheral devices that were part of System/360, but were adapted from second-generation designs, continued to use SMS circuitry instead of the newer SLT. These included the 240x-series tape drives and controllers, the 2540 card reader/punch and 1403N1 printer, and the 2821 Integrated Control Unit for the 1403 and 2540.

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.

It remained in the product line until 1979.

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.

It was commonly used on system/360 series as data entry device. #1960s #360 #card #computer #data_entry #hardware #IBM #mainframe #old #peripheral #punch #reader #system #vintage The IBM 1402 was a high speed card reader/punch introduced on October 5, 1959 as a peripheral input/output device for the IBM 1401 computer. 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.

Located to the immediate right of the operator's station, the card reader was used to transfer information on IBM punched cards into the IBM 701 Data Processing System. It could read 150 cards a minute. The card-feeding mechanism in the 711 was similar to that in the IBM 402 Accounting Machine and included two sets of reading brushes.

IBM 1442 - Wikipedia It was the 1401 that transferred input data from slow peripherals (such as the IBM 1402 Card Read-Punch) to tape, and transferred output data from tape to the card punch, the IBM 1403 Printer, or other peripherals.
