The SC-3000 (Sega Computer 3000) is the first computer to be designed and manufactured by Sega.
It was first released in July of 1983 in Japan, and serves as the home computer equivalent of the SG-1000 (Sega Game 1000) cartridge-based video game console. The SC-3000 is an 8-bit home computer almost identical in nature to the SG-1000, but with a built-in keyboard and support for more hardware expansions.
The SC-3000 was released in various countries including Japan, Australia, New Zealand, France, Italy and Finland, as an entry-level machine for the home. The SC-3000 was distributed in France under the Yeno brand, achieving mild success in 1983/1984.
