Bet you've never seen this before.
This is exceedingly rare: It's a prototype of the SNES-CD console, which was initially created as part of a proposed partnershp between Nintendo and Sony over a quarter-century ago.
It was found by the son of a businessman who had ties with a former Sony executive (rumored to be Olafur Olafsson, a chief executive at Sony Interactive Entertainment in 1991), and these images first popped up on Reddit and then on Assembler Games .
The son, going by the name of "Dnldbld" will try to find the power supply for the system; if he can, we're intensely jealous.
This thing is so rare that the features, like a horizontal volume slider in the front and an assortment of outputs at the back, weren't public knowledge. If you didn't know, Nintendo and Sony tried to work together on a console and at the Consumer Electronics Show in 1991, Sony showed off the Nintendo-endorsed SNES-CD with the additional PlayStation brand.
But Nintendo announced at the same show that they'd be partnering with Phillips instead, which really pissed off Sony boss Ken Kutaragi. That's when he resolved to make a console without Nintendo's help and, well, you know the rest. Maybe not the best plan, Ninty. You created a superpower in video games by jilting a company at the altar, so-to-speak.
