The GNU Debugger (GDB) is a portable debugger that runs on many Unix-like systems and works for many programming languages, including Ada, C, C++, Objective-C, Free Pascal, Fortran, Go and partially others.
In proprietary software, an end-user license agreement (EULA) or software license agreement is the contract between the licensor and purchaser, establishing the purchaser's right to use the software. The license may define ways under which the copy can be used, in addition to the automatic rights of the buyer including the first sale doctrine and 17 U.S.C. § 117.
DR-DOS is an operating system of the DOS family, written for IBM PC-compatible personal computers. It was originally developed by Gary A. Kildall's Digital Research and derived from Concurrent PC DOS 6.0, which was an advanced successor of CP/M-86. As ownership changed, various later versions were produced with names including Novell DOS and Caldera OpenDOS.
Digital Research, Inc. was a company created by Gary Kildall to market and develop his CP/M operating system and related 8-bit, 16-bit and 32-bit systems like MP/M, Concurrent DOS, FlexOS, Multiuser DOS, DOS Plus, DR DOS and GEM. It was the first large software company in the microcomputer world. Digital Research was based in Pacific Grove, California.
IBM PC DOS is a discontinued operating system for the IBM Personal Computer, manufactured and sold by IBM from the early 1980s into the 2000s.
Step-Saver Data Systems, Inc. v. Wyse Technology was a case in the U.S. Court of Appeals for the Third Circuit primarily concerned with the enforceability of box-top licenses and end user license agreements (EULA) and their place in U.S. contract law. During the relevant period, Step-Saver Data Systems was a value-added reseller, combining hardware and software from different vendors to offer a fully functioning computer system to various end users. Step-Saver's products included software produced by Software Link, Inc (TSL), computer terminals produced by Wyse Technology, and main computers produced by IBM. The fundamental question raised in this case was whether the shrinkwrap licenses accompanying TSL's software were legally binding, given that different terms were negotiated over the phone with Step-Saver prior to receiving physical copies of the software. The case was first heard in the United States District Court for the Eastern District of Pennsylvania, where the court ruled that the shrinkwrap licenses were legally binding. However, the U.S. Court of Appeals for the Third Circuit subsequently reversed this decision, ruling that the shrinkwrap licenses were not legally binding.
Retail software is computer software typically installed on PC type computers or more recently delivered via the Internet. Traditionally this software was delivered via physical data storage media sold to end consumer but very few companies still provide their software using physical media. The software is typically sold under restricted licenses or in the case of cloud-based software sold as Software-as-a-Service (SaaS) model.
PCBoard (PCB) was a bulletin board system (BBS) application first introduced for DOS in 1983 by Clark Development Company. Clark Development was founded by Fred Clark. PCBoard was one of the first commercial BBS packages for DOS systems, and was considered one of the "high end" packages during the rapid expansion of BBS systems in the early 1990s. Like many BBS companies, the rise of the Internet starting around 1994 led to serious downturns in fortunes, and Clark Development went bankrupt in 1997. Most PCB sales were of two-line licenses; additional line licenses were also available.
Multiuser DOS is a real-time multi-user multi-tasking operating system for IBM PC-compatible microcomputers.
The Major BBS was bulletin board software developed between 1986 and 1999 by Galacticomm. In 1995 it was renamed Worldgroup Server and bundled with a user client interface program named Worldgroup Manager for Microsoft Windows. Originally DOS-based, two of the versions were also available as a Unix-based edition, and the last versions were also available for Windows NT-based servers.
The Hyperion is an early portable computer that vied with the Compaq Portable to be the first portable IBM PC compatible. It was marketed by Infotech Cie of Ottawa, a subsidiary of Bytec Management Corp., who acquired the designer and manufacturer Dynalogic in January 1983. In 1984 the design was licensed by Commodore International in a move that was forecast as a "radical shift of position" and a signal that Commodore would soon dominate the PC compatible market. Despite computers being "hand-assembled from kits" provided by Bytec and displayed alongside the Commodore 900 at a German trade show as their forthcoming first portable computer, it was never sold by Commodore and some analysts downplayed the pact. The Hyperion was shipped in January 1983 at C$4995, two months ahead of the Compaq Portable.
Apple II serial cards primarily used the serial RS-232 protocol. They most often were used for communicating with printers, Modems, and less often for computer to computer data transfer. They could be programmed to interface with any number of external devices which were RS-232 compatible. Most serial cards had speed ranges starting from 110 bit/s up to 19,200 bit/s, however some could be modified to go much faster. The most popular and widely used of these cards was Apple Computer's Super Serial Card, a solid design that was often copied for maximum software compatibility of the end product.
BSD licenses are a family of permissive free software licenses, imposing minimal restrictions on the use and distribution of covered software. This is in contrast to copyleft licenses, which have share-alike requirements. The original BSD license was used for its namesake, the Berkeley Software Distribution (BSD), a Unix-like operating system. The original version has since been revised, and its descendants are referred to as modified BSD licenses.
Bundling of Microsoft Windows is the installation of Microsoft Windows in computers before their purchase. Microsoft encourages original equipment manufacturers (OEMs) of personal computers to include Windows licenses with their products, and agreements between Microsoft and OEMs have undergone antitrust scrutiny. Users opposed to the bundling of Microsoft Windows have sought refunds for Windows licenses, arguing that the Windows end-user license agreement entitles them to return unused Windows licenses for a cash refund. Although some customers have successfully obtained payments, others have been less successful.
DOS is a platform-independent acronym for disk operating system which became common shorthand for the popular family of disk operating systems for x86-based IBM PC compatibles. DOS primarily consists of Microsoft's MS-DOS and a rebranded IBM version under the name PC DOS, both of which were introduced in 1981. Later compatible systems from other manufacturers are DR DOS, ROM-DOS, PTS-DOS, Embedded DOS, FreeDOS (1998), and RxDOS. MS-DOS dominated the IBM PC compatible market between 1981 and 1995.
VM/386 is a multitasking operating system or 'control program' that took early advantage of the capabilities of Intel's 386 processor. By utilizing Virtual 8086 mode, users were able to run their existing text-based and graphical DOS software in safely separate environments. The system offered a high degree of control, with the ability to set memory and CPU usage limits. Unique CONFIG.SYS and AUTOEXEC.BAT files could be configured for each application, and even different DOS versions. In 1991 the vendor announced intentions to support DPMI 1.0 in VM/386.
FrontDoor was one of the most popular mailers in the FidoNet-compatible networks in the 1990s acting as the physical representation of the written network node connection and mail handling standards. It was an MS-DOS-based product written by Joaquim Homrighausen. The FrontDoor system contained a Mailer, an Editor, a Terminal, a serial port device driver and configuration utilities. FrontDoor was first released in 1986.
The Multiuser DOS Federation (MDOS) was an industry alliance to promote the growth and acceptance of multi-user DOS-based solutions on 286, 386 and 486 computers. It was formed in July 1990. The idea was to reduce costs by allowing workgroups to run DOS applications from a shared PC while working on terminals or workstations.
