Nintendo PlayStation: Rare unreleased games console goes up for auction

Almost 30 years after it was canned, an unreleased games console built together by industry giants Sony and Nintendo has gone up for auction.
The Nintendo PlayStation was the result of a secret collaboration between the Japanese tech firms in the early 90s, however the project never entered production and Sony would go on to release their own system in 1994.

Nintendo, famous for hit franchises such as Super Mario and The Legend Of Zelda, was the market leader at the time and the introduction of the PlayStation changed the face of the gaming industry.
