The Sharp Nintendo Television or Game Television is a television produced by Sharp Corporation with a built-in licensed Famicom. The system was licensed by Nintendo and was released in 1983 to Japanese markets, and supported until 1989. It was noted for having a clearer picture quality than the original setup requiring a Famicom and composite video through an RF Modulator connection.
The system featured two built-in programs, JR GRAPHIC and TV NOTE, and in Japan it was shipped with a multicart containing cut down versions of Donkey Kong Jr. and Donkey Kong Jr. no Sansuu Asobi.
