This 1200 came in with no right mouse button clicks working. After looking it over and removing all of the old capasitors it was clear it had some pretty extensive leaking under them. You can also see the results of that leakage. Several traces and VIA had been corroded to the point of no longer doing the job they intended to do. After several hours of cleanup the final result was a working 1200 and a much nicer looking one at that!
