Information:  - MS-DOS (; acronym for "Microsoft Disk Operating System") is a discontinued operating system for x86-based personal computers mostly developed by Microsoft. It was the most commonly used member of the DOS family of operating systems, and was the main operating system for IBM PC compatible personal computers during the 1980s and the early 1990s, when it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system by Microsoft Corporation.  - Martian Memorandum is a dystopian cyberpunk / noir graphic adventure game that was originally released in 1991 for the MS - DOS . It was developed and published by Access Software . The game is the second in the series of Tex Murphy mysteries ; its immediate sequel is Under a Killing Moon . The game is set in 2039 , several years after Mean Streets .  - San Francisco (SF) (Spanish for Saint Francis) officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California. It is the birthplace of the United Nations. Located at the north end of the San Francisco Peninsula, San Francisco is about in area, making it the smallest countyand the only consolidated city-countywithin the state of California. With a density of about 18,451 people per square mile (7,124 people per km), San Francisco is the most densely settled large city (population greater than 200,000) in California and the second-most densely populated major city in the United States after New York City. San Francisco is the fourth-most populous city in California, after Los Angeles, San Diego, and San Jose, and the 13th-most populous city in the United Stateswith a census-estimated 2015 population of 864,816. The city and its surrounding areas are known as the San Francisco Bay Area, and are a part of the larger OMB-designated San Jose-San Francisco-Oakland combined statistical area, the fifth most populous in the nation with an estimated population of 8.7 million.  - IBM PC compatible computers are those similar to the original IBM PC, XT, and AT, able to run the same software and support the same expansion cards as those. Such computers used to be referred to as PC clones, or IBM clones. They duplicate almost exactly all the significant features of the PC architecture, facilitated by IBM's choice of commodity hardware components and various manufacturers' ability to reverse engineer the BIOS firmware using a "clean room design" technique. Columbia Data Products built the first clone of the IBM personal computer by a clean room implementation of its BIOS.  - Tex Murphy is a series of adventure games designed by Chris Jones. The eponymous main character is portrayed in live-action by Chris Jones himself. He is characterized as a down-on-his-luck private investigator in a post-nuclear future San Francisco, borrowing tropes from both the film noir and cyberpunk genres.  - x86 is a family of backward compatible instruction set architectures based on the Intel 8086 CPU and its Intel 8088 variant. The 8086 was introduced in 1978 as a fully 16-bit extension of Intel's 8-bit based 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16-bit address. The term "x86" came into being because the names of several successors to Intel's 8086 processor end in "86", including the 80186, 80286, 80386 and 80486 processors.  - The future is what will happen in the time after the present. Its arrival is considered inevitable due to the existence of time and the laws of physics. Due to the apparent nature of reality and the unavoidability of the future, everything that currently exists and will exist can be categorized as either permanent, meaning that it will exist forever, or temporary, meaning that it will end. The future and the concept of eternity have been major subjects of philosophy, religion, and science, and defining them non-controversially has consistently eluded the greatest of minds. In the Occidental view, which uses a linear conception of time, the future is the portion of the projected time line that is anticipated to occur. In special relativity, the future is considered absolute future, or the future light cone.  - Under a Killing Moon is a 1994 point-and-click adventure interactive movie video game. It is the third installment in the "Tex Murphy" series of adventure games produced by Access Software. In it, the detective Tex Murphy finds himself unwittingly involved in the affairs of a dangerous cult.   - Cyberpunk is a subgenre of science fiction in a future setting that tends to focus on society as "high tech low life" featuring advanced technological and scientific achievements, such as information technology and cybernetics, juxtaposed with a degree of breakdown or radical change in the social order.  - Microsoft Windows (or simply Windows) is a metafamily of graphical operating systems developed, marketed, and sold by Microsoft. It consists of several families of operating systems, each of which cater to a certain sector of the computing industry with the OS typically associated with IBM PC compatible architecture. Active Windows families include Windows NT, Windows Embedded and Windows Phone; these may encompass subfamilies, e.g. Windows Embedded Compact (Windows CE) or Windows Server. Defunct Windows families include Windows 9x; Windows 10 Mobile is an active product, unrelated to the defunct family Windows Mobile.
