An anonymous reader writes: Several months ago, we got a look at a weird bit of technology: a Nintendo PlayStation prototype made in the late '80s during an unusual partnership between Sony and Nintendo. Despite cries of "hoax" and "fake," the console turns out to be real. Engadget got to try it out, X-ray it, and even open the device up to try repairing the CD drive. They brought in Daniel Cheung, a retro console technician from Restart Workshop, and he said, "I got to see the real deal so I can't discredit it. And there's even an OS. You can't question it. It can't be fake. Going back to the chips we saw earlier on the logic board: NEC used to make gaming consoles, and Sony also participated here. And with Nintendo as part of this team, you just can't discredit this."
