Palmtex Portable Videogame System
You’ll never complain about the simplistic graphics and monochromatic green screen on the original Nintendo Game Boy again after laying eyes on the Palmtex Portable Videogame System, which went through a bunch of different names in its brief existence. Game cartridges were snapped onto the back of the lid of the clamshell folding system, along with a light box that illuminated a pitiful colored sprite overlay paired with a monochromatic LCD that would cover and uncover parts of the graphics. Its design is hard to wrap your head around, but you can see it in action here, playing one of three games ever released for the portable system. You can come to your own conclusions about why it failed.
