The A1000, or Commodore Amiga 1000, was Commodore's initial Amiga personal computer, introduced on July 24, 1985 at the Lincoln Center in New York City. Machines began shipping in September with a base configuration of 256 KB of RAM at the retail price of 1295 USD. A 13-inch (330 mm) analog RGB monitor was available for around 300 USD bringing the price of a complete Amiga system to 1595 USD. Before the release of the Amiga 500 and A2000 models in 1987, the A1000 was simply called Amiga.

The Commodore Amiga 4000, or A4000, was the successor of the A2000 and A3000 computers. There are two models, the A4000/040 released in October 1992 with a Motorola 68040 CPU, and the A4000/030 released in April 1993 with a Motorola 68EC030.The A4000 originally came in a white desktop box with a separate keyboard. Later Commodore released an expanded tower version called the A4000T.Unlike most other Amiga models, early A4000 machines have the CPU mounted in an expansion board using a special CPU slot. The motherboard has no CPU at all. Later revisions of the A4000 have the CPU and 2 MB RAM surface mounted on the motherboard in an effort to reduce costs.

The Atari 2600 is a video game console released in October 1977. It is credited with popularizing the use of microprocessor-based hardware and cartridges containing game code, instead of having non-microprocessor dedicated hardware with all games built in. The first game console to use this format was the Fairchild Channel F; however, the Atari 2600 is credited with making the plug-in concept popular among the game-playing public.

The Commodore 64 is an 8-bit home computer introduced by Commodore International in January, 1982. Volume production started sometime in the spring of 1982. Preceded by the Commodore VIC-20 and Commodore MAX Machine, the C64 features 64 kilobytes (65 536 bytes) of memory with sound and graphics performance that were superior to IBM-compatible computers of that time. It is commonly known as the C64 or C=64 and occasionally referred to as CBM 64 (Commodore Business Machines Model number 64), or VIC-64.

The Nintendo Entertainment System (abbreviated to NES or Nintendo) is an 8-bit video game console that was released by Nintendo in North America, Europe and Australia in 1985. In most of Asia, including Japan (where it was first launched in 1983), China, Vietnam, Singapore, and the Philippines, it was released as the Family Computer (ファミリーコンピュータ?), commonly abbreviated as the Famicom (ファミコン?, or FC for short). In South Korea, it was known as the Hyundai Comboy (현대 컴보이) and was distributed by Hyundai Electronics. In Russia, although it has never been officially distributed by Nintendo and there were no official representatives, it was known as Dendy (Де́нди). In South Asia, it was known as the Tata Famicom.

The Super Nintendo Entertainment System or Super NES (also called SNES and Super Nintendo) is a 16-bit video game console that was released by Nintendo in North America, Europe, Australasia (Oceania), and South America between 1990 and 1993. In Japan and Southeast Asia, the system is called the Super Famicom (スーパーファミコン?, officially adopting the abbreviated name of its predecessor, the Family Computer), or SFC for short. In South Korea, it is known as the Super Comboy (슈퍼 컴보이) and was distributed by Hyundai Electronics. Although each version is essentially the same, several forms of regional lockout prevent the different versions from being compatible with one another.

The Nintendo 64 (ニンテンドウ, Nintendō Roku Jū Yon?, NINTENDO64), often abbreviated as N64, is Nintendo's third home video game console for the international market. Named for its 64-bit CPU, it was released on June 23, 1996 in Japan, September 29, 1996 in North America, March 1, 1997 in Europe and Australia, September 1, 1997 in France and December 10, 1997 in Brazil. It is Nintendo's last home console to use Game Paks to store games (Nintendo switched to a MiniDVD-based format for the Nintendo GameCube, then to standard DVD-sized discs for the Wii); handhelds in the Game Boy line, however, continued to use the Game Pak.The N64 was released with two launch games, Super Mario 64 and Pilotwings 64, and a third in Japan, Saikyō Habu Shōgi. The N64's suggested retail price was US$199 at its launch and it was later marketed with the slogan "Get N, or get Out!". The N64 sold 32.93 million units worldwide. The Nintendo 64 was released in at least eight variants with different colors and sizes. An assortment of limited edition controllers were sold or used as contest prizes during the N64's lifespan.

The Sega Master System is an 8-bit cartridge-based video game console that was manufactured by Sega and was first released in 1986. Its original Japanese incarnation was the Sega Mark III (later models of the system used the "Master System" name). In the European market, this console launched Sega onto a competitive level comparable to Nintendo, due to its wider availability, but failed to put a dent in the North American and Japanese markets. The Master System was released as a direct competitor to the Nintendo Entertainment System in the third videogame generation. Despite its shaky performance in the major territories, it enjoyed over a decade of life in smaller markets.

The Mega Drive (メガドライブ?) is a fourth-generation video game console released by Sega in Japan in 1988 and Europe in 1990. The console was released in North America in 1989 under the name Genesis, as Sega was unable to secure legal rights to the Mega Drive name in that region. The Mega Drive, heavily marketed as "16-bit" due to its hardware, was Sega's fifth home console and the successor to the Sega Master System, with which it is electronically compatible.

The Dreamcast (Japanese: ドリームキャスト Dorīmukyasuto?) was the last video game console made by Sega, and is the successor to the Sega Saturn. The Dreamcast is part of the sixth generation of video game consoles and was released in late 1998, before its contemporaries - the PlayStation 2, the Nintendo GameCube and the Xbox.Sega discontinued the Dreamcast in North America in November 2001 and withdrew entirely from the console hardware business. However, support of the system continued in Europe and Oceania until 2002 and Japan; where consoles were still sold until 2006 and new licensed games continued to be released.According to Bernie Stolar, former President and CEO of Sega of America, the Dreamcast was canceled because the new chairman of Sega wanted the company to focus on software.Despite its short lifespan, the Dreamcast was widely hailed as ahead of its time, and is still held in high regard for pioneering online console gaming—it was the first console to include a built-in modem and Internet support for online play. As of 2009, the console is still supported through various homebrew video game releases.
