The SG-1000 (Japanese: エスジー・セン Hepburn: Esu Jī Sen), also known as the Sega Computer Videogame SG-1000, is a cartridge-based home video game console manufactured by Sega and released in Japan, Australia, and other countries. It was Sega's first entry into the home video game hardware business, and provided the basis for the more successful Master System. Introduced in 1983, the SG-1000 was released on the same day that Nintendo released the Family Computer (Famicom for short) in Japan. The SG-1000 was released in several forms, including the SC-3000 computer and the redesigned SG-1000 II (エスジー・セン・ツー Esu Jī Sen Tsū, also known as the SG-1000 Mark II), released in 1984.
