The opening bid was set for $31,000 and the auction ended on February 27 with a winning bid $300,000. With the buyers premium added in, the cost comes to $360,000 (thanks, Polygon). Many expected the device to sell for quite a bit more, especially since the owner was offered $1.2 million for it at one point. Developed in a joint effort by Sony and Nintendo around 1992, this was the last remaining prototype of the alleged 200 created. The others were either lost or destroyed. The prototype features a slot for Super Famicom and Super Nintendo games and a CD-ROM drive which was meant to play discs. While the drive was not working when it was found in 2009, it has been repaired and can play music discs.
