Partial success!! Using a G3 iMac, Virtual PC6 and Win XP I have loaded the Polar Precision Performance SW. Ok so far. Performing a Sonic Link and it recognised the internal mic, and starts downloading in data. At about 30% complete I then get an error from the Polar software. I've tried chainging the volume settings for the internal mic, and seem to get best results using the 22khz sample rate.
