This is complete with original box, manual, all chess pieces, even original syrofoam! Ok, well it's missing the small booklet explaining the rules of the game of chess. Like who needs that? The included manual has a lot of that anyway like how the machine does enpassant, castling, etc. I tested the unit with 6 D batteries and works great that way. I never bought the ac adapter that was "not included in the box but sold separately" kind of thing. The display isn't as bright as we are used to nowadays but quite readable (see photos). Very cool and not a scratch on it!
