When Sony first started developing the PlayStation in the early 90s, it wasn't intending to do it alone - it was working with Nintendo to build a CD-reading version of the Super Nintendo. As we now know though, during development relations between the two companies broke down and the tie-up was abandoned, leading to the separate creation of the original PlayStation and the cartridge-based Nintendo 64. The "Nintendo PlayStation" quickly became part of gaming legend.
So it is brilliant that our pals over at Kotaku UK have spotted one Reddit user's photos that are purported to be of a prototype for the hybrid machine. Note that it takes both cartridges and CDs, and how it has SNES-style controller ports, but PS1 style power and reset buttons.
User Dnldbld described how they found the machine - a story that sounds almost too good to be true:
"My dad worked for a company, apparently one of the guys he used to work with, I think his name was Olaf, used to work at Nintendo and when my dads company went bankrupt, my dad found it in a box of 'junk' he was supposed to throw out... I have not had a chance to boot her up, I don't have a power cable at the moment, but it seems like it's a pretty common DC cable. I'll have to get one and see how it goes."
It could conceivably be an elaborate hoax but given the contents of the photos... that would be pretty damn elaborate. Kotaku has reached out to try to verify the story. You can head over there to see all of the photos. [Kotaku UK]
