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 It was withdrawn from marketing in February 1985.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 RPG II language. Hardware The 5340 System Unit contained the processing unit, the disk storage and the 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 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 programs. The CSP was the governor, a diff ...

IBM System/32
The IBM System/32 (IBM 5320) introduced in January 1975 was a midrange computer with built-in display screen, disk drives, printer, and database report software. It was used primarily by small to midsize businesses for accounting applications. RPG II was the primary programming language for the machine. Overview The 16-bit single-user System/32, also known as the IBM 5320, was introduced in 1975, and it was the successor to the IBM System/3 model 6 in the IBM midrange computer line. IBM described it as "the first system to incorporate hardware and comprehensive application software." ''The New York Times'' described the ''32'' as "a compact computer for first‐time users with little or no computer programming experience." Within 40 months, "the System/32 had surpassed the IBM System/3 as the most installed IBM computer." The computer looked lika large office deskwith a very small six-line by forty-character display and a keyboard similar to an IBM keypunch. Having the appearan ...

IBM Midrange Computers
Midrange computers, or midrange systems, were a class of computer systems that fell in between mainframe computers and microcomputers. This class of machine emerged in the 1960s, with models from Digital Equipment Corporation ( PDP line), Data General (NOVA), Hewlett-Packard (HP3000) widely used in science and research as well as for business - and referred to as minicomputers. IBM favored the term "midrange computer" for their comparable, but more business-oriented systems. IBM Midrange Systems * System/3 was the first IBM midrange system (1969) * System/32 (introduced in 1975) was a 16-bit single-user system also known as the IBM 5320. * System/34 (1977) was intended to be a successor to both the 3 and the 32. * System/38 (1979) was the first midrange system to have an integrated relational database management system (DBMS). The S/38 had 48-bit addressing, and ran the CPF operating system. * System/36 (1983) had two 16-bit processors with an operating system that supporte ...

MS-DOS
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax, and capabilities. Beginning in 1988 with DR-DO ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

IBM PC Compatible
IBM PC compatible computers are similar to the original IBM PC, XT, and AT, all from computer giant IBM, that are able to use the same software and expansion cards. Such computers were referred to as PC clones, IBM clones or IBM PC clones. The term "IBM PC compatible" is now a historical description only, since IBM no longer sells personal computers after it sold its personal computer division in 2005 to Chinese technology company Lenovo. The designation "PC", as used in much of personal computer history, has not meant "personal computer" generally, but rather an x86 computer capable of running the same software that a contemporary IBM PC could. The term was initially in contrast to the variety of home computer systems available in the early 1980s, such as the Apple II, TRS-80, and Commodore 64. Later, the term was primarily used in contrast to Apple's Macintosh computers. These "clones" duplicated almost all the significant features of the original IBM PC architectures. ...

System/36
The IBM System/36 (often abbreviated as S/36) was a midrange computer marketed by IBM from 1983 to 2000 - a multi-user, multi-tasking successor to the System/34. Like the System/34 and the older System/32, the System/36 was primarily programmed in the RPG II language. One of the machine's optional features was an off-line storage mechanism (on the 5360 model) that utilized "magazines" – boxes of 8-inch floppies that the machine could load and eject in a nonsequential fashion. The System/36 also had many mainframe features such as programmable job queues and scheduling priority levels. While these systems were similar to other manufacturer's minicomputers, IBM themselves described the System/32, System/34 and System/36 as "small systems" and later as midrange computers along with the System/38 and succeeding IBM AS/400 range. The AS/400 series and IBM Power Systems running IBM i can run System/36 code in the System/36 Environment, although the code needs to be recompiled ...

System/34 BASIC
IBM System/34 BASIC was an interpreter for the IBM System/34 midrange computer. System/34 BASIC was first offered in 1978, and as such, contained many of the trappings that a BASIC program would have encountered in the time period of the TRS-80, or many other offerings of the 1970s and early 1980s. As such, S/34 BASIC uses conventions that are no longer standard in modern BASICs, such as line numbers, and does not support newer features such as WHILE/WEND, DO/ENDDO, WITH/END WITH, procedures, properties, and so forth. BASIC conventions BASIC interpreters written in the 1970s tended to "do odd things odd ways." For example, on the Apple II, a programmer could embed a DOS command into a program via PRINT, when prefaced by the character string . PEEK and POKE could be used in various BASICs to examine memory content or change it, or even to create an ad hoc machine language program and then run it. System/34 BASIC tends to stay away from these odd conventions; however, the progra ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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. However, due to its declining popularity and the retirement of experienced COBOL programmers, programs are being migrated to new platforms, rewritten in modern languages or replaced with software packages. Most programming in COBOL is now purely to maintain existing applications; however, many large financial institutions were still developing new systems in COBOL as late as 2006. 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 ...
