Sears video Arcade II(atari) questions...
 

Anyone have one of these? In need of some help with connecting to a newer TV. Also. I can;t seem to be able to get a controller back together and was looking for some service manuals if they exist.

It probably has an output cable with an RCA phono-type plug. That originally connected to a TV/game switch that had a 300-ohm output. If your unit has the cable with RCA plug, you can buy an RCA-to-F-connector adapter and plug it into a TV's antenna or cable input, then set the TV to channel 3 or 4.

I cannot help with a service manual; you might need to look at the other controller (if you have two) for ideas.
