I don't have a lot to add here, but my thought is this: Assuming good condition, why would it have worked in the 80s for touring (exactly what its made for), but not now? It's interesting to think about what the release of subsequent products and marketing does to our brains in regards to the products that came before. Broken or not, they suddenly don't work? I'm guilty of this thought process as well, but I try not to be.
