Game Gear console with TV Tuner
The
TV Tuner plugs into the
cartridge slot of your
Game Gear, turning it into an LCD colour television. It has both antenna and mono A / V inputs, so you can use a VCR, camcorder or another
video game console via the A / V. Because of the short battery life of the Game Gear (under 2 hours), it doesn't make a particularly good TV, unless you also have the
AC adapter.
