Back in 1991, long before the release of the original Playstation, Sony asked Nintendo to help them build a CD-based console system. The professional relationship lasted for less than a year, but the two companies managed to produce 200 prototype PlayStations featuring both companies' logos before disbanding later in 1991. Nearly all of these prototypes, which can play both CD-based games and Super Nintendo games, were destroyed, but at least one still exists. A Denver, Colorado man was able to find the extremely rare console in his father's attic and posted pictures online.
The console looks like an old PC with a Super Nintendo controller and a slot for Super Nintendo. The unmistakable SNES controller bears the Sony PlayStation logo, which is undeniably strange to video game fans. Take a look at more pictures and a video below, courtesy of Polygon.
