Things You'll Need
Instructions
Buy an adapter to connect the RCA-type cable from the Atari system to the coaxial cable port on your television. The adapter must have a male F connector (for coaxial cable) and a female "phono" RCA connector. This adapter is available from some retail electronics stores.
Screw the male F connector into the coaxial cable port of the television. Then connect the RCA cable from the Atari system to the female RCA port on the adapter.
Turn your television to the appropriate channel. Try channel 3 or 4 first. If neither of these work, consult your television owner's manual.
Plug the Atari's power cable into an electrical outlet, put one of your games in the system and have a blast.
