Have you tried crazykong.com? Typically they have a really good site for this type of thing. If this was one of the places you already looked then I apologize.
Seriously? The online manuals make it appear that these are totally separate manuals. I have the operation manual but it doesn't have schematics. You're suggesting they're missing from mine? I've been watching for schematics for years. You're saying I just need to start shopping for an op manual again and ask the seller if it has the schematics in it?
