The Sega 32x is an add-on for the Sega Mega Drive. It expands the system's processing power with two 32-bit processors and a 3D graphics processor. It had it's own ROM cartridges and collection of games. The 32x was intended to be a low-cost 32-bit console while Sega worked on the Saturn, but it's rushed release and small game collection led to it being a commercial failure.
Our 32x has the power supply and connecting cable and has serial number 041000836.
