The SG-1000 [lower-alpha 1] 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 limited release in Australia and New Zealand.

Contents

The SG-1000 was released in several forms, including the SC-3000 computer and the redesigned SG-1000 II [lower-alpha 2] released in 1984. The SG-1000 and the SC-3000 both support a library of 76 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, was one of the top five arcade game manufacturers active in the United States, as company revenues rose to $214 million. [4] 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. [5] [6] 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. [7] Nakayama received permission to proceed. [8]

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. [9] The "SG" in the console's name is an abbreviation for "Sega Game", [10] and the console is also sometimes referred to as the "Mark I". [11] To keep costs down while ensuring sufficient longevity, Sega opted to create the platform from popular off-the-shelf components. [9]

The SG-1000 was first released in Japan on July 15, 1983, at ¥15,000. [10] It was released on the same day as Nintendo launched the Family Computer (Famicom) in Japan. [8] [12] It was released simultaneously with the SC-3000, [8] [10] [13] as well as the upgraded SC-3000H. [14] Though Sega themselves only released the SG-1000 in Japan, rebranded versions were released in several other markets worldwide. Released at nearly the same time as the Japanese version, the SG-1000 was released in Australia through John Sands Electronics [8] and in New Zealand by Grandstand Leisure. [9] The console also saw a release in Italy and Spain, [11] but was not released in the larger video game markets of the United States, United Kingdom, or Germany. [12] Despite this, an unauthorized clone system known as the Telegames Personal Arcade was produced and made available in the United States and Taiwan, and is able to play SG-1000 and ColecoVision games. [8] An additional release of the SG-1000 in Taiwan was done by Aaronix. [9] The console enjoyed a brief period of popularity in Taiwan before the market was taken over by cheaper Famicom clones. [15]

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. [9] Former Sega consumer hardware development head Hideki Sato stated that because Sega had not predicted the SG-1000 would sell so well, the company became more enamored with developing video game consoles. [16] 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 . [9] Shortly after launch, Gulf and Western began to divest itself of its non-core businesses after the death of company founder Charles Bluhdorn, [17] 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. [18]

Following the buyout, Sega released another console, the SG-1000 II, on July 31, 1984 [13] [11] at ¥15,000. [19] It is sometimes referred to as the "SG-1000 Mark II". [11] The SG-1000 II replaced the hardwired joystick with two detachable joypads. [8] Sato disliked the original cartridges, saying they looked like "small black tombstones" when inserted in the console, and later remarked that his proudest achievement of the SG-1000 era was replacing them with the "cheerier", pocket-sized Sega My Cards. [9] Sega also employed popular owarai comedy duo Tunnels to provide celebrity endorsement for the console. [9] Japanese company Tsukuda Original Co., Ltd. created the Othello Multivision, based around the SC-3000 and SG-1000 hardware. [20]

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. [9] The SG-1000 was also coming up against game consoles from companies including Tomy and Bandai. [8] This would result in the release of the Sega Mark III in Japan in 1985, which later became the Master System worldwide. [11] The last cartridge released was Portrait of Loretta on February 18, 1987. [21] In 2006, the GameTap subscription gaming service added an emulator of the SG-1000, and several playable titles. [22]

The SG-1000 is powered by an 8-bit Zilog Z80 central processing unit running at 3.58  MHz. Its video processor is a Texas Instruments TMS9918A, capable of displaying up to 16 colors, and its sound processor is a Texas Instruments SN76489. [8] [16] The system includes 8  kbit (1  KB) of RAM. [23] The controller is hardwired to the system in the original model, and detachable in the SG-1000 II. Video and audio output are supplied through an RF switch. [8] Power is supplied through a 9 V DC connector connected to an AC adapter. [23] [24] [25]

Several peripherals exist for the SG-1000 series. Available at ¥13,800 at its time of release, the SK-1100 keyboard connects through the expansion slot and is compatible with all models. [26] 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 . [27] The C-1000 Card Catcher, sold at ¥1,000, allows players to play Sega My Card titles. [28] Additional accessories existed solely for use with the SC-3000, including the SR-1000 cassette deck, [29] the SP-400 4-color plotter printer, [30] and the SF-7000 expansion device which adds a floppy disk drive and additional memory. [31]

Sega's software library for the SG-1000 and SC-3000 comprises 42 game cartridges and 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. [21] 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. [8] Hideki Sato stated that Sega lacked adequate staff to develop games for the console at the time. [16] SC-3000/SG-1000 games were continued to be produced after the launch of the Mark III in 1985. The last two SC-3000/SG-1000 cartridge games were The Castle in 1986 and Portrait of Loretta in 1987. The final Sega My Card game for the SC-3000/SG-1000 was The Black Onyx , also in 1987. [32]

Reception

The SG-1000 console series (including the Mark III) sold over 1.4 million units in Japan as of 1988, [2] with the original SG-1000 model having sold 400,000 units in Japan. [1] The SC-3000 home computer model sold 120,000 units in Japan during 1983. [3]

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". [11] Writing for Wired, Chris Kohler criticized the poor response of the controller's joystick and the lack of an RCA output. He said the release timing hurt its success; "[al]though its graphics were of better quality than most consoles on the market, it had the bad luck to be released in the same month as Nintendo's world-changing Famicom, which had killer apps like Donkey Kong and could run circles around Sega's hardware." [8] Of its legacy, Kohler said, "Few have heard of it, even fewer have played it, and the games weren't that great anyway." [8] By contrast, Luke Plunkett of Kotaku recognized that "while all this makes it sound like the SG-1000 was a bit of a misfire, it was still important in the development of Sega's home console business." [12]

Hideki Sato reflected positively on the innovations in the development of the SG-1000, but admitted that the console had limitations because of how new the market was and that Sega was inexperienced in developing for a video game console at the time. According to Sato, "The problem was, while we knew how to make arcade games, we didn’t really know anything about console development. In fact, the very idea of a “consumer” market for video games was unheard of then: back then it was just a 'new business' idea." [16]

<span class="mw-page-title-main">Third generation of video game consoles</span> Third video game console generation, including the Nintendo Entertainment System

In the history of video games, the third generation of video game consoles, commonly referred to as the 8-bit era, began on July 15, 1983, with the Japanese release of two systems: Nintendo's Family Computer and Sega's SG-1000. When the Famicom was released outside of Japan, it was remodeled and marketed as the Nintendo Entertainment System (NES). This generation marked the end of the video game crash of 1983, and a shift in the dominance of home video game manufacturers from the United States to Japan. Handheld consoles were not a major part of this generation; the Game & Watch line from Nintendo and the Milton Bradley Microvision that were sold at the time are both considered part of the previous generation due to hardware typical of the second generation.

The history of the Nintendo Entertainment System (NES) spans the 1982 development of the Family Computer, to the 1985 launch of the NES, to Nintendo's rise to global dominance based upon this platform throughout the late 1980s. The Family Computer or Famicom was developed in 1982 and launched in 1983 in Japan. Following the North American video game crash of 1983, the Famicom was adapted into the NES which was launched in North America in 1985. Transitioning the company from its arcade game history into this combined global 8-bit home video game console platform, the Famicom and NES continued to aggressively compete with the next-generation 16-bit consoles including the 1988 Sega Genesis. The platform was succeeded by the Super Famicom in 1990 and the Super Nintendo Entertainment System in 1991, but its support and production continued until 1995. Interest in the NES has been renewed by collectors and emulators, including Nintendo's own Virtual Console platform.

The Sega Card, known in Japan as Sega My Card, is a memory card format used as game storage for the SG-1000/SC-3000 and the Mark III / Master System. Produced from 1985 to 1987 by Mitsubishi Plastics, the cards are plugged into onboard cardslots or into compatible adapters. Several versions of the format were created, including a rewritable one that allows new titles to be downloaded to a card. While substantially cheaper to produce than cartridges, the storage limitations of the format resulted in Sega exclusively distributing games on cartridges. Despite the failure of the Sega Card, NEC found more success with its own memory card format, the HuCard, which was the primary storage medium for its PC Engine game console.

<span class="mw-page-title-main">History of Sega</span> History of Japanese video game company

The history of Sega, a Japanese multinational video game and entertainment company, has roots tracing back to American Standard Games in 1940 and Service Games of Japan in the 1950s. The formation of the company known today as Sega is traced back to the founding of Nihon Goraku Bussan, which became known as Sega Enterprises, Ltd. following the acquisition of Rosen Enterprises in 1965. Originally an importer of coin-operated arcade games to Japan and manufacturer of slot machines and jukeboxes, Sega began developing its own arcade games in 1966 with Periscope, which became a surprise success and led to more arcade machine development. In 1969, Gulf and Western Industries bought Sega, which continued its arcade game business through the 1970s.

In the video game industry, a console war describes the competition between two or more video game console manufacturers in trying to achieve better consumer sales through more advanced console technology, an improved selection of video games, and general marketing around their consoles. While console manufacturers are generally always trying to out-perform other manufacturers in sales, these console wars engage in more direct tactics to compare their offerings directly against their competitors or to disparage the competition in contrast to their own, and thus the marketing efforts have tended to escalate in back-and-forth pushes.
