You have dry joints under the 68060 socket. I have encountered (and repaired) numerous CSPPCs with this problem, including my own.

It is repairable with an ordinary soldering iron, however, extreme care must be taken as it can be very easy to ruin the socket.

Basically, it involves removing the 060, and using a very clean soldering iron, without any excess solder on the tip, heating each individual socket from the top until the soldered joint underneath melts and repairs the joint. It's really a job for an experienced technician, as the right amount of heat over the right amount of time is needed to effect a repair, without melting the plastic socket frame, or damaging the pins by filling with solder etc.

I have successfully repaired several boards with this method.
