The IBM 3270 is a family of block oriented display and printer computer terminals introduced by IBM in 1971 and normally used to communicate with IBM mainframes. The 3270 was the successor to the IBM 2260 display terminal. Due to the text color on the original models, these terminals are informally known as green screen terminals. Unlike a character-oriented terminal, the 3270 minimizes the number of I/O interrupts required by transferring large blocks of data known as data streams, and uses a high speed proprietary communications interface, using coaxial cable.
In computing, a code page is a character encoding and as such it is a specific association of a set of printable characters and control characters with unique numbers. Typically each number represents the binary value in a single byte.
Extended Unix Code (EUC) is a multibyte character encoding system used primarily for Japanese, Korean, and simplified Chinese (characters).
Disk Operating System/360, also DOS/360, or simply DOS, is the discontinued first member of a sequence of operating systems for IBM System/360, System/370 and later mainframes. It was announced by IBM on the last day of 1964, and it was first delivered in June 1966. In its time, DOS/360 was the most widely used operating system in the world.
A keypunch is a device for precisely punching holes into stiff paper cards at specific locations as determined by keys struck by a human operator. Other devices included here for that same function include the gang punch, the pantograph punch, and the stamp. The term was also used for similar machines used by humans to transcribe data onto punched tape media.
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.
The IBM System/3 was an IBM midrange computer introduced in 1969, and marketed until 1985. It was produced by IBM Rochester in Minnesota as a low-end business computer aimed at smaller organizations that still used IBM 1400 series computers or unit record equipment. The first member of what IBM refers to as their "midrange" line, it also introduced the RPG II programming language. It is the first ancestor in the product line whose current version is the IBM i series and includes the highly successful AS/400.
The IBM 4300 series are mid-range systems compatible with System/370 that were sold from 1979 through 1992. They featured modest electrical and cooling requirements, and thus did not require a data center environment. They had a disruptive effect on the market, allowing customers to provide internal IBM computing services at a cost point lower than commercial time-sharing services. All 4300 processors used a 3278-2A, 3279-C or 3205 display console rather than a 3210 or 3215 keyboard/printer console.
DOS/V is a Japanese computing initiative starting in 1990 to allow DOS on IBM PC compatibles with VGA cards to handle double-byte (DBCS) Japanese text via software alone. It was initially developed from PC DOS by IBM for its PS/55 machines, but IBM gave the driver source code to Microsoft, who then licensed a DOS/V-compatible version of MS-DOS to other companies. Kanji fonts and other locale information are stored on the hard disk rather than on special chips as in the preceding AX architecture. As with AX, its great value for the Japanese computing industry is in allowing compatibility with foreign software. This had not been possible under NEC's proprietary PC-98 system, which was the market leader before DOS/V emerged. DOS/V stands for "Disk Operating System/VGA". In Japan, IBM compatible PCs became popular along with DOS/V, so they are often referred to as "DOS/V machine" or "DOS/V pasocom" even though DOS/V operating systems are no longer common.
The IBM 3790 Communications System was one of the first distributed computing platforms. The 3790 was developed by IBM's Data Processing Division (DPD) and announced in 1974. It preceded the IBM 8100, announced in 1979.
The IBM 3270 PC, released in October 1983, is an IBM PC XT containing additional hardware that, in combination with software, can emulate the behaviour of an IBM 3270 terminal. It can therefore be used both as a standalone computer, and as a terminal to a mainframe.
Operating System/Virtual Storage 1, or OS/VS1, is a discontinued IBM mainframe computer operating system designed to be run on IBM System/370 hardware. It was the successor to the Multiprogramming with a Fixed number of Tasks (MFT) option of System/360's operating system OS/360. OS/VS1, in comparison to its predecessor, supported virtual memory. OS/VS1 was generally available during the 1970s and 1980s, and it is no longer supported by IBM.
The history of IBM mainframe operating systems is significant within the history of mainframe operating systems, because of IBM's long-standing position as the world's largest hardware supplier of mainframe computers. IBM mainframes run operating systems supplied by IBM and by third parties.
IBM 5550 is a personal computer series that IBM marketed in Japan, Korea, Taiwan and China in the 1980s and 1990s, for business use customers. In Japan, it was introduced in 1983 and promoted as "Multistation 5550 (マルチステーション5550)" because it had three roles in one machine: a PC, a word processing machine which was traditionally marketed as a machine different from a PC in Japan, and an IBM-host attached terminal.
The Personal System/55 (パーソナルシステム/55) or PS/55 is a personal computer series released from IBM Japan in 1987.
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 information was saved securely in storage for future reference. The IBM 5280 followed the design lead of the IBM 3740 but was totally programmable, enhanced the speed and storage of the processor, the speed and amount of available memory for the software to use, the size and clarity of the display, and afforded multiple diskette drives with larger capacity on each diskette. And, it sported an enhanced styling.
IBM Fujisawa—located in Fujisawa, Kanagawa, Japan—was a manufacturing and development site of IBM Japan, Ltd., a subsidiary of IBM Corporation.
IBM 2245 Kanji Printer was the line printer of the IBM Kanji System, announced in 1971, that allowed printing of Japanese text on IBM System/360 and System/370 mainframe computers. Later, it would also support printing of Korean and Traditional Chinese text.
Several mutually incompatible versions of the Extended Binary Coded Decimal Interchange Code (EBCDIC) have been used to represent the Japanese language on computers, including variants defined by Hitachi, Fujitsu, IBM and others. Some are variable-width encodings, employing locking shift codes to switch between single-byte and double-byte modes. Unlike other EBCDIC locales, the lowercase basic Latin letters are often not preserved in their usual locations.
