Releasing sometime in 1992 across much of the world, the Watara Supervision was sold very cheaply at only $49.95, but failed to captivate the market with it's boring games. Specification-wise, the system is weak, containing a 8-bit 65SC02, a 160×160 monochrome screen, and basic peripheral capability.
