Sigh. It took so long to find a Compact Mac... In Italy, Apple never sold much, until the advent of OSX and iPod and all that stuff.

Well, I'll post the result of the acid cleaning tomorrow, and try to check the traces with a multimeter anyway. Except for the hours spent working on, it it's not gonna cost much money on components, so I think I won't drop by the wayside in just a week even if i know it's gonna be useless. xx(

Update: those are three pictures of what the board looks like after the acid removal.
