Hi Lin,

So, you mean as te connection as SAA -> CE6353 -> QT1010?

I'll pull the card again, desolder the can and try to see where those
SDA/SCL tracks run, I have some fine test probes that I can use to probe
those points, the company I work for sells the Ingin & ECT board test
probes for testing of bare and loaded PCB's, so probing won't be a
problem.

I also found that Eucalyptus oil is great for removing the paint on the
tops of some IC chips ;o)
