My aunt worked at operating service and when they closed she kept the old style switch boards, it's the kind where you connect the calls by moving plug from one spot to another. Its before the motherboard era. Has anyone ever messed with this type of thing. It's burred in her garage so I don't want to even attempt anything unless it's going to be worth it. Sorry about no pictures but I can't get to it without a lot of effort.
Does anyone know if these types switch boards contain gold plating or valuable scrap?
