The SG-1000, which stands for Sega Game 1000, is a cartridge-based video game console manufactured by Sega. This system marked Sega's entry into the home video game hardware business, which they would continue to be in until the end of the Dreamcast in 2001. While the system was not very popular, it was the basis for the more successful Sega Master System.
Game manufacturer Tsukada Original made Othello Multivision, an SG-1000 clone. Bit Corp's Dina 2-in-1 Colecovision clone was brought to North America by a company called Telegames. Telegames called its clone the Telegames Personal Arcade, which could play Colecovision and SG-1000 games.
A caveat is the SG-1000's surprisingly wide availability on Taiwan's secondary market. This console is highly significant in Taiwan as one of its first and best-remembered consoles, where it was manufactured and sold (very briskly) under license as "阿羅士". This was striking in that in the same time period from 1981 to 1986, Famicom games were widely pirated as standalone and multi-carts (replete with rudimentary switch banks to select the active ROM), as well as no less than three different pirated versions of the Atari 2600 with boastful monikers characteristic of the times ("冒險家" ('Adventurer'), "賓果" ('Delight'), "強棒創造者" ('Steadfast Creator')).
Taiwan, among a few countries, also received a Mark IV version of the console--very likely a modified Sega Master System II--and the Mark- naming convention was further extended to the Mega Drive/Genesis ('Mark V').
The SG-1000 runs all SC-3000 games and applications, with the exception of Music and Basic Cartridges. The machine could be used just like the SC-3000, provided one had the keyboard attachment ready. The console also had an optional game card reader add-on called the Card Catcher that allowed for the use of Sega game card software.
The Card Catcher would become built into the SG-1000 Mark III, as well as the first version of the Sega Master System.
The SG-1000 Mark III, a yet newer version in Japan with improved video hardware and an increased amount of RAM, would be redesigned to become the Sega Master System.
