I dug out my atari 2600 to find out----

I was missing my power cable. It was a special one with the big box end for the wall and small prong for insertion in machine.
I have some games that are good and not in reissue game sets with games included in module cabinet.

I purchased the reissue cabinets hoping the power adapter might work on my original game set from 80s- did not fit right.

sure would like to play some old favorites of mine- the cartridge ones (one game per cartridge)
