Visiting the in-laws with my wife and they brought out a box of old Atari stuff they had and gave it to me...
The 2600 Vader and Coleco tape deck are dusty and will need cleaning.
The Smurfs game and tapes are mint.
Star Raiders with the pad and overlay, Haunted House, and Phoenix are all mint.
The Atari also included 4 paddles, 2 standard joysticks, and a Power System joystick.
