Ex-employee reveals 14-year-old Sega Pluto prototype
An ex-SEGA employee revealed that he has owned an unreleased prototype of SEGA Pluto, which is a SEGA Saturn with a Netlink built in.
The ex-employee didn't reveal his name, but he goes by the screen name "Super Magnetic" on the AssemblerGames forum. He explained that the prototype ended up on his desk after its original owner left the company. Later on, Super Magnetic left the company too, but he collected all the items on his desk, including the Pluto, in a box.
