I have had my Sharp 702 for 7 or 8 years now and it has become obsolete with the MP3 age of today. I have tons of music stuck on mini discs that I would love to be able to dump into itunes if there is a way. the 702 appears to only have and optical line in and a mic line in plus the headphones jack. Is there a way to transfer my mini discs to my mac ??
