So, first things first. Sega actually shipped some pretty insane gear. A handheld console that used full-size Genesis cartridges? Check. A sophisticated Tamagotchi that our own editor-in-chief developed games for? Yessir. Something called a "32X" that stacked on top of an already sizable home console? Sure, why not? Given the outfit's history, the item you're peering at above doesn't feel all that outlandish. According to one Super Magnetic -- a self-proclaimed ex-employee of Sega -- this is Pluto.
As the story goes, Sega was pondering the release of a Saturn variant that included an embedded NetLink device. At the time, online console gaming was in its earliest stages, and someone likely assumed that they could kickstart things by including an Ethernet jack from the get-go. Of course, Pluto never saw the light of day in the consumer world -- thankfully, you can partake in a few more shots of what could've been at the source link below.
