S > SEGA > SG-1000 Mark II   


Sega
SG-1000 Mark II

Very similar to the SG-1000, the SG-1000 Mark II was just a minor update consisting mainly of cosmetic changes.

The case was redesigned and the joysticks of the Mark I were replaced by joypads which could be stored in built-in holders located on either side of the console. There was also built-in port where a keyboard could be attached, effectively turning the console into a computer. However, the Mark II was still outsold by it's computer counterpart, the SC-3000.

In 1985 the Mark II was replaced by the Mark III, the first version of the Master System.
