IBM 5256
The IBM 5280 was a data entry system introduced by IBM in 1980 that expanded on the earlier IBM 3740 of 1973. The 3740 was essentially a computer terminal that recorded a user's data entry onto an 8-inch floppy disk instead of older storage media like punch cards or paper tape. The 5280 expanded on this model by including a complete low-end computer system that could be customized for different roles, ran faster, had more storage both internally and on the disks, and a better display. It also sported an enhanced styling, looking more like a contemporary all-in-one microcomputer compared to the 3740 large desk-like appearance. History Data entry terminals IBM had developed an efficient batch processing concept as the basis for most of its computer installations. In this approach, users did not interact with the computers directly, instead they would prepare their programs and data on separate systems, often mechanical or electromechanical, and then give the resulting information to ...

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. The "Diskette" was more commonly known as an 8-inch floppy disk. It was succeeded in 1980 by the IBM 5280 which added full programmability. The term "IBM 3740" is sometimes used metonymically to refer to the floppy disk recording format it introduced, which was the direct ancestor of the IBM PC floppy format which would become the industry standard in the 1980s and 1990s. History The system was announced in January, 1973; became available in the second quarter of that year; and was withdrawn from marketing in December, 1983. It was developed by IBM's General Systems Division facility in Rochester, Minnesota. The IBM 3740 system was intended to replace the traditional unit record equipment, using t ...

The New York Times
''The New York Times'' (''NYT'') is an American daily newspaper based in New York City. ''The New York Times'' covers domestic, national, and international news, and publishes opinion pieces, investigative reports, and reviews. As one of the longest-running newspapers in the United States, the ''Times'' serves as one of the country's Newspaper of record, newspapers of record. , ''The New York Times'' had 9.13 million total and 8.83 million online subscribers, both by significant margins the List of newspapers in the United States, highest numbers for any newspaper in the United States; the total also included 296,330 print subscribers, making the ''Times'' the second-largest newspaper by print circulation in the United States, following ''The Wall Street Journal'', also based in New York City. ''The New York Times'' is published by the New York Times Company; since 1896, the company has been chaired by the Ochs-Sulzberger family, whose current chairman and the paper's publ ...

COBOL
COBOL (; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL is still widely used in applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs. Many large financial institutions were developing new systems in the language as late as 2006, but most programming in COBOL today is purely to maintain existing applications. Programs are being moved to new platforms, rewritten in modern languages, or replaced with other software. COBOL was designed in 1959 by CODASYL and was partly based on the programming language FLOW-MATIC, designed by Grace Hopper. It was created as part of a U.S. Department of Defense effort to create a portable programming language for data pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM RPG
RPG is a high-level programming language for business applications, introduced in 1959 for the IBM 1401. It is most well known as the primary programming language of IBM's midrange computer product line, including the IBM i operating system. RPG has traditionally featured a number of distinctive concepts, such as the program cycle, and the column-oriented syntax. The most recent version is RPG IV, which includes a number of modernization features, including free-form syntax. Platforms The RPG programming language originally was created by IBM for their 1401 systems. IBM later produced implementations for the 7070/72/74 and System/360; RPG II became the primary programming language for their midrange computer product line, (the System/3, System/32, System/34, System/38, System/36 and AS/400). There have also been implementations for DEC VAX, Sperry Univac BC/7, Univac system 80, Siemens BS2000, Burroughs B700, B1700, Hewlett Packard HP 3000, the ICL 2900 series, ...

IBM 5250
IBM 5250 is a family of block-oriented terminals originally introduced with the IBM System/34 midrange computer systems in 1977. It also connects to the later System/36, System/38, and IBM AS/400 systems, and to IBM Power Systems systems running IBM i, as well as the Series/1 minicomputer. Components 5250 devices can be directly attached to the host or communicate remotely using Synchronous Data Link Control (SDLC) at up to 9600bit/s. Devices can also be clustered or daisy-chained. In 1980 the 5250 system consisted of the following components: * 5251 Display Station. The monochrome text-only display can be either 960 characters, formatted as 12 lines of 80 characters, or 1920 characters as 24 lines of 80 characters. Upper and lower case is standard. Text attributes consist of blink, high intensity, reverse video, non-display, underscore, and a unique ''column separator'' that causes the field to be preceded and followed by a vertical bar. 5251 and 5252 input ''format contro ...

IBM AS/400
The IBM AS/400 (Application System/400) is a family of midrange computers from IBM announced in June 1988 and released in August 1988. It was the successor to the System/36 and System/38 platforms, and ran the OS/400 operating system. Lower-cost but more powerful than its predecessors, an estimated 111,000 installations existed by the end of 1990 and annual revenue reaching $14 billion that year, increasing to 250,000 systems by 1994, and about 500,000 shipped by 1997. A key concept in the AS/400 platform is IBM i#TIMI, Technology Independent Machine Interface (TIMI), a platform-independent instruction set architecture (ISA) that is translated to native machine language instructions. The platform has used this capability to change the underlying processor architecture without breaking application compatibility. Early systems were based on a 48-bit Complex instruction set computer, CISC instruction set architecture known as the ''Internal Microprogrammed Interface'' (IMPI), original ...

IBM System/34
The IBM System/34 was an IBM midrange computer introduced in 1977. It was withdrawn from marketing in February 1985. It was a multi-user, multi-tasking successor to the single-user System/32. It included two processors, one based on the System/32 and the second based on the System/3. Like the System/32 and the System/3, the System/34 was primarily programmed in the IBM RPG, RPG II language. Hardware The 5340 System Unit contained the processing unit, the disk storage and the floppy disk, diskette drive. It had several access doors on both sides. Inside, were swing-out assemblies where the circuit boards and memory cards were mounted. It weighed and used 220V power. The IBM 5250 series of Computer terminals, terminals were the primary interface to the System/34. Processors S/34s had two processors, the Control Storage Processor (CSP), and the Main Storage Processor (MSP). The MSP was the workhorse, based on System/3 architecture; it performed the instructions in the computer pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
