After some trouble shooting, it turned out to be the PS. I forgot at the time, but I have an Atari 5200 PS that I use for my Intellivision II. I plugged it into the switch box and the LED came on. The system is big, but I think it looks great along with the controllers. Since then I've put in a few hours and think it's a great system. I only have about 11 common games including: Jungle Hunt, Football, Star Raiders, Super Breakout, Pac Man, Dig Dug, Galaxian, etc. The only game where I feel the controller is a real pain is Pac Man. Unfortunately, both of the controllers are missing the rubber boots so I'm unsure how much of a change that makes. The games I have are good so far, but I bought the system to play Fractalus, Gremlins, Pitfall II, Space Dungeon, Baseball, etc. Looking forward to adding those, Best refurb controllers, and a track ball in the future. I think that mods are very cool for A/V and controllers, but I personally prefer the original experience. Thanks for the responses and feedback; much appreciated.
