The M2 was to be a 64-bit add-on for the 3DO. Kinda like putting a 32X on a Genesis/Megadrive. It was to go beneath the system and allow it to play M2 CDs. When 3DO decided to stop pushing their system and just work on games for other consoles, they said they would likely license the M2 technology out to other companies. While the item in that auction looks to me like a mini PC, it may have been designed using some of the technology derived from the development of the 3DO M2. (Especialy likely, as Panasonic was one of companies that licensed, built, and sold the original 3DO systems.)
