Basically, it's coming from everywhere. I think it's mostly the enamel
burning off the traces, and from the melting Z80.

Huh? The solder melted in a lot of the places, and the paper clips stuck to
it. There's a lot of fried traces, too. Instead of trying to fix it, I'd
be MUCH better off just finding another board.
