Commodore 64 in the context of 8-bit computing

An IBM PC compatible is any personal computer that is hardware- and software-compatible with the IBM Personal Computer (IBM PC) and its subsequent models. Like the original IBM PC, an IBM PC–compatible computer uses an x86-based central processing unit, sourced either from Intel or a second source like AMD, Cyrix or other vendors such as Texas Instruments, Fujitsu, OKI, Mitsubishi or NEC and is capable of using interchangeable commodity hardware such as expansion cards. Initially such computers were referred to as PC clones, IBM clones or IBM PC clones, but the term "IBM PC compatible" is now a historical description only, as the vast majority of microcomputers produced since the 1990s are IBM compatible. IBM itself no longer sells personal computers, having sold its division to Lenovo in 2005. "Wintel" is a similar description that is more commonly used for modern computers.

The designation "PC", as used in much of personal computer history, has not meant "personal computer" generally, but rather an x86 computer capable of running the same software that a contemporary IBM or Lenovo PC could. The term was initially in contrast to the variety of home computer systems available in the early 1980s, such as the Apple II, TRS-80, and Commodore 64. Later, the term was primarily used in contrast to Commodore's Amiga and Apple's Macintosh computers.

Commodore International Corporation (CI), also known as Commodore International Limited, was a home computer and electronics manufacturer with its head office in The Bahamas and its executive office in the United States founded in 1976 by Jack Tramiel and Irving Gould. It was the successor company to Commodore Business Machines (Canada) Ltd., established in 1958 by Tramiel and Manfred Kapp. Commodore International, along with its U.S. subsidiary Commodore Business Machines, Inc. (CBM), was a significant participant in the development of the home computer industry, and at one point in the 1980s was the world's largest in the industry.

The company released its first home computer, the Commodore PET, in 1977; it was followed by the VIC-20, the first ever computer to reach one million units of sales. In 1982, the company developed and marketed the world's best selling computer, the Commodore 64; its success made Commodore one of the world's largest personal computer manufacturers, with sales peaking in the last quarter of 1983 at $49 million (equivalent to $129 million in 2024). However an internal struggle led to co-founder Tramiel quitting, then rivaling Commodore under Atari Corporation joined by a number of other employees. Commodore in 1985 launched the Amiga 1000 personal computer — running on AmigaOS featuring a full color graphical interface and preemptive multitasking — which would initially become a popular platform for computer games and creative software. The company did particularly well in European markets; in West Germany, Commodore machines were ubiquitous as of 1989.

Kung-Fu Master, known as Spartan X in Japan, is a 1984 beat 'em up game developed and published by Irem for arcades. It was distributed by Data East in North America. Designed by Takashi Nishiyama, the game was based on Hong Kong martial arts films. It is a loose adaptation of the Jackie Chan, Sammo Hung and Yuen Biao film Wheels on Meals (1984), called Spartan X in Japan. The protagonist Thomas is named after Jackie Chan's character in the film. It is also heavily inspired by the Bruce Lee film Game of Death (1972), which was the basis for the game's concept. Nishiyama, who had previously designed the side-scrolling shooter Moon Patrol (1982), combined fighting elements with a shoot 'em up gameplay rhythm. Irem and Data East exported the game to the West without the Spartan X license.

The game was a major commercial success, topping the Japanese arcade charts and becoming America's second highest-grossing arcade game of 1985, while receiving critical acclaim for its fast-paced, side-scrolling gameplay and detailed, colorful graphics. A port for the Nintendo Entertainment System (known as the Famicom in Japan) was developed by Nintendo under the direction of Shigeru Miyamoto, released as Spartan X in Japan and Kung Fu in the West, selling 3.5 million copies worldwide. It was also one of the top five best-selling Commodore 64 games of 1986. It spawned the sequel Spartan X 2 (1991) and the spiritual successors Trojan (1986) and Vigilante (1988).

A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a single integrated circuit microprocessor. The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors such as the MOS Technology 6502, Zilog Z80, and Intel 8088. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive

Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense). An early use of the term "personal computer" in 1962 predates microprocessor-based designs. (See "Personal Computer: Computers at Companies" reference below). A "microcomputer" used as an embedded control system may have no human-readable input and output devices. "Personal computer" may be used generically or may denote an IBM PC compatible machine.

Cut & Paste is a word processor published in 1984 for the Apple II, Atari 8-bit computers, Commodore 64, IBM PC compatibles, and IBM PCjr. It is one of the few productivity releases from game developer and publisher Electronic Arts, along with the contemporaneous Financial Cookbook. In the UK it was distributed by Ariolasoft.

Originally sold for US$50, Cut & Paste was praised for its user-friendliness and criticized as overly simplistic. Magazine advertisements proclaimed, "If you can learn to use this word processor in 90 seconds, can it really be any good?" and the slogan on the box read "The Remarkably Simple Word Processor".

Colorburst is one part of the composite sync used in analog television signals. It consists of a "packet" of the sine wave chroma subcarrier and is used as a reference to decode color information in the video. By synchronizing an oscillator with the colorburst at the back porch (beginning) of each scan line, a television receiver is able to restore the suppressed carrier of the chrominance (color) signals, and in turn decode the color information.

In computer graphics, a sprite is a two-dimensional bitmap that is integrated into a larger scene, most often in a 2D video game. Originally, the term sprite referred to fixed-sized objects composited together, by hardware, with a background. Use of the term has since become more general.

Systems with hardware sprites include arcade video games of the 1970s and 1980s; game consoles including as the Atari VCS (1977), ColecoVision (1982), Famicom (1983), Genesis/Mega Drive (1988); and home computers such as the TI-99/4 (1979), Atari 8-bit computers (1979), Commodore 64 (1982), MSX (1983), Amiga (1985), and X68000 (1987). Hardware varies in the number of sprites supported, the size and colors of each sprite, and special effects such as scaling or reporting pixel-precise overlap.

The Amstrad CPC (short for "Colour Personal Computer") is a series of 8-bit home computers produced by Amstrad between 1984 and 1990. It was designed to compete in the mid-1980s home computer market dominated by the Commodore 64 and the ZX Spectrum; it successfully established itself primarily in the United Kingdom, France, Spain, and the German-speaking parts of Europe, and also Canada.

The series spawned a total of six distinct models: The CPC 464, CPC 664, and CPC 6128 were highly successful competitors in the European home computer market. The later 464 plus and 6128 plus, intended to prolong the system's lifecycle with hardware updates, were considerably less successful, as was the attempt to repackage the plus hardware into a game console as the GX4000.

The Way of the Exploding Fist is a 1985 fighting game developed by Beam Software and published by Melbourne House for the Commodore 64. It was later ported to Amstrad CPC, ZX Spectrum, BBC Micro, Acorn Electron and Commodore 16. It is based on Japanese martial arts. The development team consisted of Gregg Barnett, Bruce Bayley, Neil Brennan and David Johnston.

Centipede is a 1981 fixed shooter video game developed and published by Atari, Inc. for arcades. Designed by Dona Bailey and Ed Logg, it was one of the most commercially successful games from the golden age of arcade video games, and one of the first widely played by women and girls. The primary objective is to shoot all the segments of a centipede that winds down the playing field.

Centipede was ported to Atari's own 2600, 5200, 7800, and 8-bit computers. Under the Atarisoft label, the game was sold for the Apple II, Commodore 64, ColecoVision, VIC-20, IBM PC (as a self-booting disk), Intellivision, and TI-99/4A. Superior Software published the port for the BBC Micro. Versions for the Game Boy and Game Boy Color were also produced, as well as a version for the short-lived Game.com. Other developers released more than 25 Centipede clones for home computers. It was followed by the arcade sequel Millipede in 1982. In 1998, a 3D remake for Windows, Mac, PlayStation, and Dreamcast was published by Hasbro Interactive.

Jack Tramiel (/ˈdʒæk trəˈmɛl/, trə-MEL; born Idek Trzmiel, Polish pronunciation: [ˈidɛk ˈtʂmjɛl]; December 13, 1928 – April 8, 2012) was a Polish-American businessman and Holocaust survivor, best known for founding Commodore International. The PET, VIC-20, and Commodore 64 are some home computers produced while he was running the company. Tramiel later formed Atari Corporation after he purchased the remnants of the original Atari, Inc. from its parent company. He was one of six people spotlighted when the computer was denoted "Machine of the Year" by Time magazine in 1982.

FairLight (FLT) is a warez and demo group initially involved in the Commodore demoscene, and in cracking to illegally release games for free, since 1987. In addition to the C64, FairLight has also migrated towards the Amiga, Super NES and later the PC. FairLight was founded during the Easter holiday in 1987 by Strider and Black Shadow, both ex-members of West Coast Crackers (WCC). This "West Coast" was the west coast of Sweden, so FairLight was initially a Swedish group, which later became internationalized. The name was taken from the Fairlight CMI synthesizer which Strider saw Jean-Michel Jarre use on some of his records.

Scramble is a 1981 horizontally scrolling shooter video game developed and published by Konami for arcades. It was distributed by Leijac for manufacture in Japan and Stern in North America. It was the first side-scrolling shooter with forced scrolling and multiple distinct levels, and it established the foundation for a new genre.

It was Konami's first major worldwide hit. In the United States, it sold 15,136 arcade cabinets within five months and became Stern's second best-selling game. Scramble was not ported to any major contemporary consoles or computers, but there were releases for the Tomy Tutor and Vectrex as well as dedicated tabletop/handheld versions. Unauthorized clones for the VIC-20 and Commodore 64 use the same name as the original.
