Sega Genesis/MegaDrive

   <games> A {games console} made by {SEGA}.

   The Genesis used a {Z80} [or a clone?] for its sound
   generator.  This made the Genesis compatible with {Sega Master
   System} games through a device called a "Power Base Converter"
   which basically shut down the Genesis/MegaDrive's {68000}
   {CPU} and made the Z80 the CPU.
