Sega's classic cartridge handheld console. It may not have sold anywhere near the amount of the Gameboy, but features great colour graphics and a huge inventory of games available. 

This is a job lot of eight Sega Game Gear consoles, all tested and found to not be working. Some just won't power on, others just give a corrupt screen when used. Condition is mixed, from poor to very good. Some have battery covers, some do not - check large photos.
