Thanks David!  So the card is a MIC in, nice!  I keep hoping I'd be
able to find the recording half of the SuperSonic card (I sold mine
nearly 20 years ago, kept the SuperSonic though).  I still have fond
memories of recording off audio CD and playing with AudioZap.  I
suppose there's no real point in trying to record off the GS, a modern
system running Audacity would be a more useful setup anyhow.
