Please answer the following question: Information:  - A personal computer (PC) is a multi-purpose electronic computer whose size, capabilities, and price make it feasible for individual use. PCs are intended to be operated directly by a person using a graphical user interface such as Windows. The versatility of a personal computer is greatly enhanced by the use of peripheral devices such as a keyboard, monitor, printer, mouse, speakers, and an external hard drive.  - FreeDOS (formerly Free-DOS and PD-DOS) is a free operating system for IBM PC compatible computers. It intends to provide a complete DOS-compatible environment for running legacy software and supporting embedded systems.  - PTS-DOS is a disk operating system, a DOS clone, developed in Russia by PhysTechSoft.  - A disk operating system (abbreviated DOS) is a computer operating system that can use a disk storage device, such as a floppy disk, hard disk drive, or optical disc. A disk operating system must provide a file system for organizing, reading, and writing files on the storage disk. Strictly speaking, this definition does not apply to current generations operating systems, such as versions of Microsoft Windows in use, while this definition is actually only used for older generations of operating systems.  - 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.  - DOS , short for "disk operating system", is an acronym used to describe the family of several very similar command-line computer operating systems for x86-based computers: primarily MS-DOS and PC DOS, but also DR-DOS, FreeDOS, ROM-DOS, and PTS-DOS. None of these systems were officially named "DOS", and indeed "DOS" is a general term for disk operating system.  - The Motorola 68000 ("'sixty-eight-thousand'"; also called the m68k or Motorola 68k, ""sixty-eight-kay"") is a 32-bit CISC microprocessor with a 16-bit external data bus, designed and marketed by Motorola Semiconductor Products Sector (later Freescale Semiconductor, now NXP). Introduced in 1979 with HMOS technology as the first member of the successful 32-bit m68k family of microprocessors, it is generally software forward compatible with the rest of the line despite being limited to a 16-bit wide external bus. After 37 years in production, the 68000 architecture is still in use.  - Betrayal at Krondor is a DOS-based role-playing video game developed by Dynamix and published by Sierra On-Line in the summer of 1993. "Betrayal at Krondor" takes place largely in Midkemia, the fantasy world developed by Raymond E. Feist in his "Riftwar" novels. The game is designed to resemble a book, separated into chapters and narrated in the third-person with a quick-save bookmark feature.  - Home computers were a class of microcomputers entering the market in 1977, and becoming common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single nontechnical user. These computers were a distinct market segment that typically cost much less than business, scientific or engineering-oriented computers of the time such as the IBM PC, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporaneous business computers. Their most common uses were playing video games, but they were also regularly used for word processing, doing homework, and programming.  - 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.  - A-10 Tank Killer is a flight simulation computer game for Amiga and DOS platforms developed and published by Dynamix. The game features an A-10 Thunderbolt II attack aircraft. The game was originally released for DOS in 1989 and for Amiga in 1990. Following the success of "Red Baron", version 1.5 was released in 1991 which included Gulf War missions and improved graphics and sounds. Several mission packs were sold separately. A sequel published by Sierra, "", was released in 1996.  - Silent Thunder : A- 10 Tank Killer II is a flight simulation computer game and the sequel to A- 10 Tank Killer , which was directed by Frank Evers ( CEO ) . Both games were made by Dynamix and Sierra produced Silent Thunder . It was made for Amiga and DOS platforms . In the game , the player takes the role of an American A- 10 Thunderbolt II aircraft pilot who fights in various campaigns across the world in order to keep the peace . The player character is Jack `` Loudmouth '' Haggart , a hotshot American pilot trying to make a name for himself in the U.S. Air Force . He starts off as a rookie pilot who steadily rises through the ranks with each military campaign he successfully completes . He takes orders from Commander Garrett , an unseen American officer who informs Haggart of his primary mission objectives . If Haggart completes a mission successfully , Garrett will praise Haggart for his efforts . However , if Haggart fails a mission , Garrett will lose his temper and either criticize or threaten Haggart . Battlefield intelligence is relayed to Haggart by an unnamed intelligence officer . Finally , there is Nightflight , another A- 10 pilot who is a good friend of Haggart 's . He plays a vital role in the first campaign of the game . There are few other Allied or enemy characters described in great detail throughout the game .  - AmigaOS is the proprietary native operating system of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola 68000 series of 16-bit and 32-bit microprocessors. Later versions were developed by Haage & Partner (AmigaOS 3.5 and 3.9) and then Hyperion Entertainment (AmigaOS 4.0-4.1). A PowerPC microprocessor is required for the most recent release, AmigaOS 4.  - DR-DOS (DR DOS, without hyphen up to and including version 6.0) is an operating system of the DOS family, written for IBM PC-compatible personal computers. It was originally developed by Gary 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.  - The Amiga is a family of personal computers sold by Commodore in the 1980s and 1990s. Based on the Motorola 68000 family of microprocessors, the machine has a custom chipset with graphics and sound capabilities that were unprecedented for the price, and a pre-emptive multitasking operating system called AmigaOS. The Amiga provided a significant upgrade from earlier 8-bit home computers, including Commodore's own C64.  - Dynamix, Inc. was an American developer of video games from 1984 to 2001, best known for the flight simulator "Red Baron", the puzzle game "The Incredible Machine", the "Front Page Sports" series, the acclaimed "Betrayal at Krondor," and their online multiplayer game "Tribes".
