Atari 7800 Power Supply in Wanted Posted March 13, 2020 Thanks for all the information folks. For now I am probably just going to have to hold on to hope that I stumble across one. One of my main concerns is that I don't even know if my system works. I received it a number of years ago in a trade, and was suppose to have come with the power supply, and the person never followed through.. So the whole thing may be moot. Thus my interest in trade or cheap, but I also understand other's POV in wanting to hold onto their hardware. Again I appreciate all the information! Thank you.
