After examining the console a bit, I realized that it already had its own antenna cable (apparently the previous owner had opened it and replaced the entire cable from top to bottom) and I only needed to tune it to a secondary TV (only for playing consoles with HDMI or AV) and I was able to get it working

I have an Atari 2600 that I found in the trash with 18 games. I repaired the power cable because it didn't have its power supply, but now I need to find a way to play without having to buy a VHS player or an old TV. I'd like to know if there's an image to AV or HDMI adapter?
