The <!-- See WP:JFN --> is a home video game console manufactured by Sega. It was Sega's first entry into the home video game hardware business. Developed in response to a downturn in arcades starting in 1982, the SG-1000 was created on the advice of Hayao Nakayama, president of Sega's Japanese arm, and was released on July 15, 1983, the same day that Nintendo released the Family Computer in Japan. It also had a limited release in Australia and New Zealand.

The SG-1000 was released in several forms, including the SC-3000 computer and the redesigned SG-1000 II released in 1984. The SG-1000 and the SC-3000 both support a library of 51 ROM cartridge games and 29 Sega My Card games.

A third iteration of the console, the Mark III, was released in 1985. It provided an improved custom video display processor over previous iterations and served as the basis for the Master System in 1986, Sega's first internationally released console. All SG-1000 games are fully compatible with the Mark III and the Japanese version of the Master System.

In the early 1980s, Sega Enterprises, Inc., then a subsidiary of Gulf and Western Industries, was one of the top five arcade game manufacturers active in the United States, as company revenues rose to $214&nbsp;million. A downturn in the arcade business starting in 1982 seriously hurt the company, leading Gulf and Western to sell its North American arcade manufacturing organization and the licensing rights for its arcade games to Bally Manufacturing. The company retained Sega's North American R&D operation, as well as its Japanese subsidiary, Sega Enterprises, Ltd. With its arcade business in decline, Sega Enterprises, Ltd. president Hayao Nakayama advocated that the company leverage its hardware expertise to move into the home console market in Japan, which was in its infancy at the time. Nakayama received permission to proceed.

The first model to be developed was the SC-3000, a computer with a built-in keyboard, but when Sega learned of Nintendo's plans to release a games-only console, they began developing the SG-1000 alongside the SC-3000.

The SG-1000 was first released in Japan on July 15, 1983, at ¥15,000. It was released on the same day as Nintendo launched the Family Computer (Famicom) in Japan. It was released simultaneously with the SC-3000, Though Sega themselves only released the SG-1000 in Japan, rebranded versions were released in several other markets worldwide. In November that same year as the Japanese version, the SC-3000 was released in Australia through John Sands Electronics The console also saw a release in France, Italy, and Spain, but was not released in the larger video game markets of the United States, United Kingdom, or Germany.

Due in part to the SG-1000's steadier stream of releases (21 SG-1000 games by the end of 1983, as compared to only 9 Famicom games), and in part to a recall on Famicom units necessitated by a faulty circuit, the SG-1000 sold 160,000 units in 1983, far exceeding Sega's projection of 50,000. Despite this, the three launch games, all of which were ported from Sega's VIC dual-arcade board, lacked the name recognition of Famicom launch games Donkey Kong, Donkey Kong Jr., and Popeye. so Nakayama and former Sega CEO David Rosen arranged a management buyout of the Japanese subsidiary in 1984 with financial backing from CSK Corporation, a prominent Japanese software company. Nakayama was then installed as CEO of the new Sega Enterprises, Ltd.

Following the buyout, Sega released another console, the SG-1000 II, on July 31, 1984, It is sometimes referred to as the "SG-1000 Mark II".

By 1984, the Famicom's success began to outpace the SG-1000. The Famicom had more advanced hardware, allowing it to perform smoother scrolling and more colorful sprites, and Nintendo boosted its games library by courting third-party developers, whereas Sega was less than eager to collaborate with the same companies they were competing with in arcades. The SC-3000H retains the same technical specifications as the SC-3000, but uses a plastic keyboard instead and includes some altered keycaps. Multiple controllers were created, including the SJ-200 joystick attached to the SG-1000, and the SJ-150 joypad, made for use with the SG-1000 II. A racing wheel known as the SH-400 was made for use with games such as Monaco GP. The C-1000 Card Catcher, sold at ¥1,000, allows players to play Sega My Card titles. Additional accessories existed solely for use with the SC-3000, including the SR-1000 cassette deck, the SP-400 4-color plotter printer, and the SF-7000 expansion device which adds a floppy disk drive and additional memory.

Sega's software library for the SG-1000 and SC-3000 consists of 51 game cartridges, which includes both licensed titles from Sega and also the titles released for the licensed console from Tsukuda Original Co., Ltd. called the Othello Multivision, as well as 29 Sega My Card releases that required the Card Catcher add-on. There were also 26 educational and programming cartridges for the SC-3000 that could only be played on the SG-1000 with the SK-1100 keyboard peripheral. Titles for the system include Flicky, Congo Bongo, Sega-Galaga, and Girl's Garden, the first video game programmed by Sonic the Hedgehog developer Yuji Naka. The library included licensed titles, such as Golgo 13. Packaging and game manuals came with both Japanese and English text until 1984, when manuals were switched to Japanese only and the size of the cartridge box was reduced.

Reception

The SG-1000 console series (including the Mark III) sold over units in Japan , with the original SG-1000 model having sold 400,000 units in Japan. The SC-3000 home computer model sold 120,000 units in Japan during 1983, and went on to sell about 300,000 units worldwide.

The SG-1000 made little impact on the video game industry, but has been recognized for being Sega's first video game console. Retro Gamer writer Damien McFerran said it was an "abject failure", but called it and the SG-1000 II "the Japanese forefathers of the Master System".
