A pair of unreleased Sega Pluto prototypes have been discovered!
The Pluto is an updated version of the Saturn but with a built-in NetLink modem.
Only two units are known to exist. Photos of the first emerged online by someone who claimed to have worked at Sega “a good 14 years ago”.
Then the second appeared when kidvid666 realised after seeing the story that he owned the other. In the YouTube video below kidvid666 explains that he “bought it in a flea market for a $1” and would “probably put in eBay” in the next few days.
