The Lynx rivaled the Nintendo Gameboy. The Lynx was the first color-screened handheld ever!

In 1989, Atari released a second version of the Lynx with a number of improvements including an extra hour of battery life, a sharper LCD screen, a button to switch off the backlight (to save on battery power when games are paused), a Power LED (it blinked when the battery was low) and rubber grips on the back, all encased in a smaller more rectangle-looking black casing.  The Lynx II was backward-compatible with all Lynx games and was later advertised as being able to communicate directly with the upcoming 64-bit Jaguar.

.  Nintendo and Sega did their part too with their Game Boy and Game Gear, respectively.  A few years after the re-release in 1991, stores started favoring other handhelds over the Lynx, causing it to die a slow death.

Accessories for the Lynx included the ComLynx cable for multiplayer games, AC adaptor, cigarette lighter adaptor, sun shield/sun guard, battery pack (D type) and a carrying case.

The Lynx retailed for .95.  Over 100 games were released for the system, which by the way was based on Amiga software, and another 50 were sadly never released.
