DOCS (software)
DOCS (Display Operator Console Support) was a software package for IBM mainframes by CFS Inc., enabling access to the system console using 3270-compatible terminals. Computer operators communicated with IBM mainframe computers using an electro-mechanical typewriter-like console that came standard on most IBM 360 and 370 computer, except a few upper end models that offered video consoles and the Model 20 which came standard without a console. The majority of smaller and less expensive IBM 360s and 370s came equipped with these ruggedized Selectric keyboard devices. The Selectric was a major step up from the teletypes (TTY) associated with Unix and smaller systems, but still clunky. The video consoles provided with certain models were not considered particularly user friendly, and they ignored two thirds of IBM's mainframe market, DOS and its VSE descendants. DOCS replaced or supplanted the typewriter interface with a video screen. In practice, it worked a little like present-day in ...

Mainframe Computer
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers. The term ''mainframe'' was derived from the large cabinet, called a ''main frame'', that housed the central processing unit and main memory of early computers. Later, the term ''mainframe'' was used to distinguish high-end commercial computers from less powerful machines. Design Modern mainframe design is characterized less b ...

DOS/VS
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. DOS versions BOS/360 The Basic Operating System(BOS) was an early version of DOS and TOS which could provide usable functionality on a system with as little as 8 KB of main storage and one 2311 disk drive. TOS/360 TOS/360 (Tape Operating System/360, not a DOS as such and not so called) was an IBM operating system for the System/360, used in the early days around 1965 to support the System/360 Model 30 and similar platforms. TOS, as per the "Tape" in the name, required a tape drive. It shared most of the code base and some manuals with IBM's DOS/360. TOS went through 14 releases, and was discontinued when disks such as the IBM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whitman, Massachusetts
Whitman is a town in Plymouth County, Massachusetts, United States. The population was 15,121 at the 2020 census. It is notable as being the place where the chocolate chip cookie was invented. History Whitman was first settled by Europeans in 1670 and was officially incorporated in 1875. Prior to becoming Whitman, it was formally the southern parish of the town of Abington. The new name, Whitman, was taken from Augustus Whitman, whose family who grew up in South Abington, and was adopted in 1886. Though before adopting the name Whitman, the small town was known as Little Comfort. Whitman has a rich history that is deeply rooted in the shoemaking industry. Regal Shoe and Bostonian Shoe are perhaps the most notable companies. At one time there were over 20 shoe factories and related factories making metal shanks in town. There are a few abandoned factories left, and some have been turned into condominiums. In the late 1930s, Ruth Graves Wakefield invented chocolate chip coo ...

Data Center
A data center (American English) or data centre (British English)See spelling differences. is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems. Since IT operations are crucial for business continuity, it generally includes redundant or backup components and infrastructure for power supply, data communication connections, environmental controls (e.g., air conditioning, fire suppression), and various security devices. A large data center is an industrial-scale operation using as much electricity as a small town. History Data centers have their roots in the huge computer rooms of the 1940s, typified by ENIAC, one of the earliest examples of a data center.Old large computer rooms that housed machines like the U.S. Army's ENIAC, which were developed pre-1960 (1945), were now referred to as "data centers". Early computer systems, complex to operate and ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnuson Computer Systems
Magnuson Computer Systems was a manufacturer of plug-compatible computers compatible with IBM mainframes. The Magnuson M80 range was available from the late 1970s and was successful when IBM struggled to ship machines. The company declared bankruptcy in March 1983 after IBM introduced new models and reduced prices. The Magnuson processors were aimed at the lower end of IBM's product line. They had a number of unique design features. Perhaps the most notable was the voting logic on each processor card. All of the slots in the main chassis were interchangeable. All slots were filled on only the high end model. Carlton Amdahl, son of Gene Amdahl, was Vice President of Engineering at Magnuson. He went on to work with his father at Trilogy Systems. There the "tell me three times" logic was incorporated into their chip designs at the level of individual gates and flip-flops.

Amdahl Corporation
Amdahl Corporation was an information technology company which specialized in IBM mainframe-compatible computer products, some of which were regarded as supercomputers competing with those from Cray Research. Founded in 1970 by Gene Amdahl, a former IBM computer engineer best known as chief architect of System/360, it was a wholly owned subsidiary of Fujitsu since 1997. The company was located in Sunnyvale, California. From its first machine in 1975, Amdahl's business was to provide mainframe computers that were plug-compatible with contemporary IBM mainframes, but offering higher reliability, running somewhat faster, and costing somewhat less. They often had additional practical advantages as well, in terms of size, power requirements, of being air-cooled instead of requiring a chilled water supply. This offered a price/performance ratio superior to the IBM lineup, and made Amdahl one of the few real competitors to "Big Blue" in the very high-margin computer market segment. T ...

VDOS (operating System)
Norton Commander (NC) is a discontinued prototypical orthodox file manager (OFM), written by John Socha and released by Peter Norton Computing (later acquired in 1990 by the NortonLifeLock, Symantec corporation). NC provides a text-based user interface for managing files on top of MS-DOS. It was officially produced between 1986 and 1998. The last MS-DOS version of Norton Commander, 5.51, was released on July 1, 1998. A related product, ''Norton Desktop'', a graphical shell for MS-DOS and Windows, succeeded Norton Commander. It came in two variants, ''Norton Desktop for DOS'' and ''Norton Desktop for Windows''. Background John Socha started work on Norton Commander in 1984; at the time, he called it "Visual DOS" or "VDOS". Norton Commander was easy to use because it had a constant view of two file manipulation objects at once. After starting the program the user sees two panels with file lists. Each panel can be easily configured to show information about the other panel, a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DOS/VSE
VSEn (''Virtual Storage Extended'') is an operating system for IBM mainframe computers, the latest one in the DOS/360 lineage, which originated in 1965. DOS/VSE was introduced in 1979 as a successor to DOS/VS; in turn, DOS/VSE was succeeded by VSE/SP version 1 in 1983, and VSE/SP version 2 in 1985. In February 2005, IBM announced z/VSE as successor to VSE/ESA 2.7, which was named to reflect the new System z branding for IBM's mainframe product line. In June 2021, 21st Century Software Inc announced that it had licensed the z/VSE source code from IBM with the intention of developing new versions of the operating system. As part of this transfer, z/VSE was renamed to VSEn. It is less common than z/OS and is mostly used on smaller machines. In the late 1980s, there was a widespread perception among VSE customers that IBM was planning to discontinue VSE and migrate its customers to MVS instead, although IBM relented and agreed to continue to produce new versions of VSE.
