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) --=20 Qn. Whats the differance between a Snake and a Onion? Ans.
