Bids for 'Nintendo PlayStation' console have already reached $350,000

Bidding for the only known'Nintendo-PlayStation' prototype console - the result of a failed partnership between Nintendo and Sony in 1991 - is already up to $350,000 (£268,000). The super-rare console, which is being sold with a Sony-branded SNES controller and cartridge that enables CD-Rom functionality, only went up for bids on Thursday. Potential buyers have 21 days left to bid on the console, which is being auctioned off by Dallas-based Heritage Auctions on March 6. The collectors' item is a rare artefact from a brief collaboration between the Japanese gaming giants before they took separate paths in the video game market. The rare'SNES-PlayStation' was one of 200 prototypes made - and the rest are thought to be destroyed.
