Edos
Edos is a discontinued operating system based upon IBM's original mainframe DOS (not to be confused with the unrelated and better known MS-DOS for the IBM PC). The name stood for extended (or enhanced) disk operating system. It was later purchased by the West German computer company Nixdorf, who renamed it to NIDOS (Nixdorf Disk Operating System). In 1970, IBM announced the IBM/370 product line along with new peripherals, software products, and operating systems, including DOS/VS that supplanted DOS. Although IBM was rightly focused on their new products, the computing world was dominated by the IBM/360 line, which left a lot of users nervous about their investment. Although there were a couple of projects emulating the IBM/370 on the IBM/360 (e.g., CFS, Inc.), other companies took a different approach, extending the then-current (and limited) DOS. The Computer Software Company (TCSC) took the latter approach. Starting in 1972, they developed Edos, Extended Disk Operating Sys ...

Nixdorf Computer
Nixdorf Computer AG was a West German computer company founded by Heinz Nixdorf in 1952. Headquartered in Paderborn, Germany, it became the fourth largest computer company in Europe, and a worldwide specialist in banking and point-of-sale systems. Labor for Impulstechnik When Nixdorf worked at Remington Rand Corp., he recognized the market potential for calculators. He presented his concept to a few large businesses. The Rheinisch-Westfälisches Elektrizitätswerk (RWE) in Essen showed interest and trust in his ideas, so they gave him 30,000 D-Mark. With that, Nixdorf was able to found the Labor für Impulstechnik on July 1, 1952. The same year, the company delivered their first calculator. Because of their success, the Labor für Impulstechnik delivered to major companies like the Wanderer-Werke in Cologne and the Compagnie des Machines Bull in Paris. In 1954 the company was compelled to move to another office location, because they needed more space. They invented many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DATACOM/DB
Datacom/DB is a relational database management system for mainframe computers. It was developed in the early 1970s by Computer Information Management Company and was subsequently owned by Insyte, Applied Data Research, Ameritech, and Computer Associates International, Inc. Datacom is now owned by CA Technologies (formerly Computer Associates), which renamed it to CA-Datacom/DB and later to CA Datacom/DB. Origin The genesis of modern DBMS technology occurred in the 1970s with the advent of huge databases that were cumbersome to manage and maintain. As long as most mainframe processing was done in batch mode, the rapidity of maintenance operations was not a key ingredient to success. During the 1970s however, the introduction of online systems required that information become quickly available and dynamically maintained. Some of the most dramatic changes occurred in the banking and credit industry: * Large banks needed to manage tens of millions of banking account record ...

Coherent (operating System)
Coherent is a clone of the Unix operating system for IBM PC compatibles and other microcomputers, developed and sold by the now-defunct Mark Williams Company (MWC). Historically, the operating system was a proprietary product, but it became open source in 2015, released under the BSD-3-Clause license. Development Coherent was not Unix; the Mark Williams Company had no rights to either the Unix trademark or the AT&T/Bell Labs source code. In the early years of its existence, MWC received a visit from an AT&T delegation looking to determine whether MWC was infringing on AT&T Unix property. The delegation included Dennis Ritchie, who concluded that "it was very hard to believe that Coherent and its basic applications were not created without considerable study of the OS code and details of its applications." However, he also stated that: Much of the operating system was written by alumni from the University of Waterloo: Tom Duff, Dave Conroy, Randall Howard, Johann George, and T ...

Applied Data Research
Applied Data Research (ADR) was a large software vendor from the 1960s until the mid-1980s. ADR is often described as "the first independent software vendor". Founded in 1959, ADR was originally a contract development company. ADR eventually built a series of its own products. ADR's widely used major packages included: Autoflow for automatic flowcharting, Roscoe, MetaCOBOL, an extensible macro processor for the COBOL language, and Librarian for source-code management. ADR later purchased the Datacom/DB database management system from Insyte Datacom and developed the companion product, IDEAL (Interactive Development Environment for an Application’s Life), a fourth-generation programming language. Another popular ADR product was ''The Librarian'', a version control system for IBM mainframe operating systems, now known as CA Librarian. In 1978, it was reported that ''The Librarian'' was in use at over 3,000 sites; by a decade later that number had doubled. First software patent ...

Command-line Interface
A command-line interpreter or command-line processor uses a command-line interface (CLI) to receive commands from a user in the form of lines of text. This provides a means of setting parameters for the environment, invoking executables and providing information to them as to what actions they are to perform. In some cases the invocation is conditional based on conditions established by the user or previous executables. Such access was first provided by computer terminals starting in the mid-1960s. This provided an interactive environment not available with punched cards or other input methods. Today, many users rely upon graphical user interfaces and menu-driven interactions. However, some programming and maintenance tasks may not have a graphical user interface and use a command line. Alternatives to the command-line interface include text-based user interface menus (for example, IBM AIX SMIT), keyboard shortcuts, and various desktop metaphors centered on the pointer (usual ...

Mark Williams Company
The Mark Williams Company was a small software company in Chicago, Illinois (later moved to Northbrook, Illinois) that created Coherent, one of the first Unix-like operating systems for IBM PCs and several C programming language compilers. It was founded by Robert Swartz in 1977 and discontinued operations in 1995. The name comes from the middle name of Robert Swartz's father, William Mark Swartz. Robert Swartz moved the company (originally producing a soft drink called Dr. Enuf) into software with his father's help and the company became known as the Mark Williams Company. Mark Williams won a patent lawsuit centered on 'byte ordering'. Separately and at that time, Linux had made serious inroads in the UNIX clone market. Since Coherent was a commercially available package and Linux was distributed freely on the Internet via their GNU public license, Coherent sales plummeted and Swartz had no choice but to cease operations in 1995.
