IBM sold a System/360 peripheral called the IBM 2540 which could read up to 1000 cards per minute. 2 The IBM 2540 ran electrical brushes across the surface of each card which made contact with a plate behind the cards wherever there was a hole. Once read, the System/360 family of computers represented the characters on each punch card using an

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.

If the buffer pool is constructed by a GETPOOL macro, BUFNO is not required.

I can't remember which model card reader/ punch was used with this computer. The operating system was OS/VS1 and we ran with three and sometimes four partitions. This 370 replaced an IBM 360/50, 1403 printer, 3330 drives, and 2540 card reader/punch. Rochester develops the IBM 2540 card reader/punch.

The Model 30 was designed by IBM's General Systems Division in Endicott, New York, and manufactured in Endicott and other IBM manufacturing sites outside of U.S. Late in 1981, IBM released the PROFS PRPQ, which had been developed jointly by AMOCO and IBM Many releases were made available (1983-1997), some of which were: 2021-03-27 To understand the 1401's architecture, it helps to understand how punch cards were used in that era. In 1928, IBM developed the 80-column punch card that became the standard for data processing for decades. A punch card held 80 characters, one per column, with the character represented by the holes punched in that column, as shown below. 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.
