ColecoVision in the context of Intellivision

The Magnavox Odyssey 2 (stylized as Magnavox Odyssey), also known as Philips Odyssey 2, is a home video game console of the second generation that was released in 1978. It was sold in Europe as the Philips Videopac G7000, in Brazil and Peru as the Philips Odyssey and in Japan as Odyssey2 (オデッセイ2 odessei2). The Odyssey 2 was one of the five major home consoles prior to the 1983 video game market crash, along with Atari 2600, Atari 5200, Intellivision and ColecoVision.

In the early 1970s, Magnavox pioneered the home video game industry by successfully bringing the first home console to market, the Odyssey, which was quickly followed by a number of later models, each with a few technological improvements (see Magnavox Odyssey series). In 1978, Magnavox, now a subsidiary of North American Philips, decided to release an all-new successor, Odyssey 2.

In the history of video games, the second-generation era refers to computer and video games, video game consoles, and handheld video game consoles available from 1976 to 1992. Notable platforms of the second generation include the Fairchild Channel F, Atari 2600, Intellivision, Odyssey 2, and ColecoVision. The generation began in November 1976 with the release of the Fairchild Channel F. This was followed by the Atari 2600 in 1977, Magnavox Odyssey² in 1978, Intellivision in 1979 and then the Emerson Arcadia 2001, ColecoVision, Atari 5200, and Vectrex, all in 1982. By the end of the era, there were over 15 different consoles. It coincided with, and was partly fueled by, the golden age of arcade video games. The generation also included the entry of handheld consoles, chiefly led by Nintendo’s foray into gaming led by the Blue Ocean philosophy of Gunpei Yokoi and the release of the Game & Watch in 1980. This peak era of popularity and innovation for the medium resulted in many games for second generation home consoles being ports of arcade games. Space Invaders, the first "killer app" arcade game to be ported, was released in 1980 for the Atari 2600, though earlier Atari-published arcade games were ported to the 2600 previously. Coleco packaged Nintendo's Donkey Kong with the ColecoVision when it was released in August 1982.

Built-in games, like those from the first generation, saw limited use during this era. Though the first generation Magnavox Odyssey had put games on cartridge-like circuit cards, the games had limited functionality and required TV screen overlays and other accessories to be fully functional. More advanced cartridges, which contained the entire game experience, were developed for the Fairchild Channel F, and most video game systems adopted similar technology. The first system of the generation and some others, such as the RCA Studio II, still came with built-in games while also being able to use cartridges. The popularity of game cartridges grew after the release of the Atari 2600. From the late 1970s to the mid-1990s, most home video game systems used cartridges until the technology was replaced by optical discs. The Fairchild Channel F was also the first console to use a microprocessor, which was the driving technology that allowed the consoles to use cartridges. Other technology such as screen resolution, color graphics, audio, and AI simulation was also improved during this era. The generation also saw the first handheld game cartridge system, the Microvision, which was released by toy company Milton Bradley in 1979.

The 1980s was the second decade in the industry's history. It was a decade of highs and lows for video games. The decade began amidst a boom in the arcade video game business with the golden age of arcade video games, the Atari 2600's dominance of the home console market during the second generation of video game consoles, and the rising influence of home computers. However, an oversatuation of low quality games led to an implosion of the video game market that nearly destroyed the industry in North America. Most investors believed video games to be a fad that had since passed, up until Nintendo's success with its Nintendo Entertainment System (NES, Famicom) revived interest in game consoles and led to a recovery of the home video game industry. In the remaining years of the decade, Sega ignites a console war with Nintendo, developers that had been affected by the crash experimented with PC games, and Nintendo released the Game Boy, which would become the best-selling handheld gaming device for the next two decades. Other consoles released in the decade included the Intellivision, ColecoVision, TurboGrafx-16 (PC Engine) and Sega Genesis (Mega Drive).

Notable games of the 1980s included Pac-Man, Ms. Pac-Man, Donkey Kong, Super Mario Bros., Super Mario Bros. 3, Mario Bros., Duck Hunt, Tetris, The Legend of Zelda, Metroid, Castlevania, Mega Man, Final Fantasy, Dragon Quest, Double Dragon, Punch-Out!!, Contra, Mega Man 2, SimCity, Prince of Persia, Gauntlet, Gradius, Out Run, Defender, Missile Command, Frogger, Q*bert, Dig Dug, Pitfall!, Elite, and Maniac Mansion.

Coleco Industries, Inc. (/kəˈliːkoʊ/ kə-LEE-koh) was an American company founded in 1932 by Maurice Greenberg as The Connecticut Leather Company. The name "COLECO" is an abbreviation derived from the company's original name. It was a successful toy company in the 1980s, mass-producing versions of Cabbage Patch Kids dolls and its video game consoles, the Coleco Telstar dedicated consoles and ColecoVision. While the company ceased operations in 1988 as a result of bankruptcy, the Coleco brand was revived in 2005, and remains active to this day.

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 Atari 5200 SuperSystem or simply Atari 5200 is a home video game console introduced in 1982 by Atari, Inc. as a higher-end complement for the popular Atari Video Computer System. The VCS was renamed to Atari 2600 at the time of the 5200's launch. Created to compete with Mattel's Intellivision, the 5200 wound up a direct competitor of ColecoVision shortly after its release. While the Coleco system shipped with the first home version of Nintendo's Donkey Kong, the 5200 included the 1978 arcade game Super Breakout, which had already appeared on previous Atari home platforms.

The system architecture is almost identical to that of the Atari 8-bit computers, although software is not directly compatible between them. The 5200's controllers have an analog joystick and a numeric keypad along with start, pause, and reset buttons. The 360-degree non-centering joystick was touted as offering more control than the eight-way Atari CX40 joystick of the 2600, but it was a focal point for criticism.

The Arcadia 2001 is a second-generation 8-bit home video game console released by Emerson Radio in May 1982 for a price of US$99, several months before the release of ColecoVision. It was discontinued only 18 months later, with a total of 35 games having been released. Emerson licensed the Arcadia 2001 to Bandai, which released it in Japan. Over 30 Arcadia 2001 clones exist despite the system being a commercial failure.

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.

The Zilog Z80 is an 8-bit microprocessor designed by Zilog, first released in 1976; it played an important role in the evolution of early personal computing. It was designed to be software-compatible with the Intel 8080, offering a compelling alternative due to its better integration and increased performance. Along with the 8080's seven registers and flags register, the Z80 introduced an alternate register set, two 16-bit index registers, and additional instructions, including bit manipulation and block copy/search.

Originally intended for use in embedded systems like the 8080 was, the Z80's combination of compatibility, affordability, and superior performance led to widespread adoption in video game systems and home computers throughout the late 1970s and early 1980s, helping to fuel the personal computing revolution. The Z80 was used in iconic products such as the Osborne 1, Radio Shack TRS-80, ColecoVision, ZX Spectrum, Sega's Master System and the Pac-Man arcade cabinet. In the early 1990s, it was used in portable devices, including the Game Gear and the TI-83 series of graphing calculators.
