   en.wikipedia.org/wiki/IBM_3740

   IBM 3740 Data Entry System was a data entry system that was announced by IBM in 1973. It recorded data on an 8" diskette, a new recording medium from IBM, for fast, flexible, efficient data entry to either high-production, centralized operations or to decentralized, remote operations. [ 1 ]

   en.wikipedia.org/wiki/Job_Entry_Subsystem_2/3

   The Job Entry Subsystem (JES) is a component of IBM's MVS (MVS/370 through z/OS) mainframe operating systems that is responsible for managing batch workloads. In modern times, there are two distinct implementations of the Job Entry System called JES2 and JES3. They are designed to provide efficient execution of batch jobs.

   IBM first introduced the 8-inch FDD in 1971 as a read only program load device. In 1973 IBM shipped its first read/write floppy disk drive as a part of the 3740 Data Entry System. IBM established early standards in 8" FDDs but never sold such products separately so that the industry then developed separate from IBM.

   en.wikipedia.org/wiki/Floppy-disk_controller

   IBM's 1973 introduction of the 3740 Data Entry System created the basic media standard for the 8-inch single sided floppy disk, IBM's "Type 1" diskette, which coupled with rapidly increasing requirements for inexpensive, removable direct access storage for many small applications caused a dramatic growth in drive and controller shipments.

6. IBM 5280 - Wikipedia

   en.wikipedia.org/wiki/IBM_5280

   The IBM 5280 was designed to compete with the data entry products that were available at the time. The IBM 3740 was the major data entry capability available to convert the data collected at the source, whether high volume, distributed or locally gathered, to make it available in digitized form in databases that were available to the managers and other users, and to make sure that the ...

   IBM introduces the IBM 3740 data entry system. It uses IBM's first read/write diskette, a single-sided 8-inch-diameter "memory disk"—a new recording medium to replace punched cards. [4] Each diskette can hold as much data as 3,000 standard 80-column punched cards. [5] See also: History of the floppy disk

8. IBM remote batch terminals - Wikipedia

   en.wikipedia.org/wiki/IBM_remote_batch_terminals

   The IBM 2780 and the IBM 3780 are devices developed by IBM for performing remote job entry (RJE) and other batch functions over telephone [a] lines; they communicate with the mainframe via Binary Synchronous Communications (BSC or Bisync) and replaced older terminals using synchronous transmit-receive (STR).

9. IBM Rochester - Wikipedia

   en.wikipedia.org/wiki/IBM_Rochester

   The IBM 3740 Data Entry System was developed at the facility in 1973 and the follow-on IBM 5280 Distributed Data System had its beginnings there, but was transferred in 1981 to the Austin, TX facility, where it was released for production. The advent of personal computing swallowed up this type of data entry by 1990.
