Things You'll Need
Instructions
Attach the Atari power cord to the system, and plug it in to the wall. Connect one end of the RCA output cable included with the system into the console. Though this cable looks like a composite cable, it also transmits audio, so you can't attach it directly to your TV.
Attach the other end of the Atari's RCA cable to the coaxial to RCA adapter. You need an adapter with a female port on the RCA end and a male port on the coaxial end.
Screw the coaxial end of the adapter into the antenna or cable input on your TV. Turn on the TV, and tune it to the proper input by pushing the "Input" or "Source" button on the set's remote control.
Insert a game cartridge in the Atari 2600, and connect a controller compatible with that game. Turn on the power to experience a bit of video game history.
