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. 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 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 System/360 product line. 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.

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. 1965

Punch card programmers would typically hand their cards to the actual computer operators, who would feed the cards into the IBM 2540 and then hand the printed results back to the programmer. The programmer usually didn’t see the computer at all.

punchedcardreader. IBM Punched Card reader - extract text from images of cards. The punchedCardReader python script attempts to scan images of IBM 80 column punch cards extracting any recognisable text. The IBM 1401 has a peculiar architecture, optimized to support these punch-card applications. The idea is that fixed-length fields were be delimited in memory by word marks, a sort of metadata, and then instructions operated on these arbitrary-length fields.

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. IBM 2314 Disk Drives and IBM 2540 Card Reader/Punch at the University of Michigan. Some of the most powerful early S/360s used high-speed head-per-track drum storage devices. The 3,500 RPM 2301, [ 16 ] which replaced the 7320, was part of the original S/360 announcement, with a capacity of 4Mb.

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. 2021-03-28 · The IBM 2540 Reader Punch Photo: Introduction to IBM Data Processing Systems , IBM Textbook C20-1684, 1968.
