SG-1000

The SG-1000, which stands for Sega Game 1000, is a cartridge-based video game console manufactured by Sega.
Sega released two updated versions of the console called the SG-1000 Mark II, which featured a connector for an optional plug-in SK-1100 keyboard, and 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. The SC-3000 was the home computer equivalent of the SG-1000 cartridge-based gaming console with an integrated keyboard.
