The item for sale is an Electroluminescent Backlit Keyboard compatible with the GD8000 & GD8200 Laptops from General Dynamics.  The EL keyboard includes a layer just beneath the surface that emits a green light that illuminates the white translucent keys from beneath.  There are 4 hotkey-controlled brightness levels.

 Your purchase includes the keyboard as well as the board that supplies power to the backlight and the corresponding cover.  With the included items, this keyboard can be installed on ANY General Dynamics GD8000 or GD8200, regardless of the type of keyboard currently installed.

This keyboard is a perfect replacement if your current keyboard is damaged OR if you currently have a standard keyboard and are looking to UPGRADE to the EL Backlit type.
