My wife's, her grandma's, uncle's former 2600

[Galvatron]

I just found my wife's 2600 in her closet. A sad darth vader system with lots of dust and a little copper wire hanging out where the phono end goes into the switch box. I can easily repair that but when I opened the system to find spider webs and cleaned almost everything I noticed something.

 

I'm not that good at identifing certain electronic components, but in between the power input and right difficulty switch is maybe a resistor. The wire closest to the end of the board looks like it has rust where it touches the board but looks alright underneath the board. Could it actually be rust or can an eraser get rid of it like on the contacts on carts.

 

I guess what I really want to know is what this part is for. And if it is too hard to replace in case the rust doesn't come off the board. I guess I could try the 2600 as is but I don't want to damage any games. I can play 2600 games on the 7800 if not.

Take a picture if you can with a pencil pointing to the spot you are talking about.

 

In the meantime, if the atari works don't mess with it.

As soon as I'm done moving I'll get my camera out and take a photo.
