sorry to hear that you are facing problems, but good thing that it's not total useless scrap

Yeah, this guy had many useful pieces out later... and maybe will have some more.
One more thing, while on this... I was trying to locate some info, and have found another place/source of vary manuals/links etc.... bunch of stuff, which maybe useless, but some day you may be looking for something, bookmark it, if you have not seen that page:
