The Sega Game -1000 (SG-1000) is a second generation cartridge-based video game console. This was Sega’s first entry into the video game hardware business for which they stayed in for many years. However, the SG-1000 was not nearly as popular as successor game consoles like the Sega Master System of the Sega Saturn.

In July 1984, Sega released an updated version called the SG-1000 II. It had a re-styled shell and the connector for the optional plug-in SK-1100 keyboard has been moved from the rear to the front. It was initially priced at ¥15,000.
