Yes, it's the Atari Lynx -- the portable gaming system that was ahead of its time but was absolutely stomped into oblivion by the Nintendo Game Boy.
The Lynx had a lot of advantages over the Game Boy -- color graphics, better sound and a groovy innovation or two that should have made it a contender in the market. However, it also had wretched battery life and lacked the marketing dollars, third-party support and the franchises that Nintendo enjoyed. Still, the Lynx was a fine little system and I still play mine quite a bit.
