Hi All: I hope this is the right forum for the question... I'm a long time MD owner and supporter...I own both an older portable (MZ-R37) and a console model (MDS-JE470). I have toyed with the idea of downloading MP3 formatted tunes to my portable MD and use it instead of the CD walkman that I also own...the MD is just more convenient! Anyway, has anyone ever set up a USB connection from an Apple G4 computer to an MD portable. I have an MD-PORT AN1, but I'm not sure if I have the necessary software or the right cables to get the job done. I appreciate any help! Thanks, Kevin M
