You are bidding on a used Atari "THE400" mini console.  This is a recreation of the Atari 400 computer but in smaller form.   Included in this auction are everything you see in pics -- the Atari 400 Mini console, the "special" joystick that comes with it (extra buttons), the USB power cord (you will need to provide your own USB-A power source), HDMI cable, Quick Start guide, and box.
