FrankMD-Mac

Hi guys, first time poster here so apologies if this is answered elsewhere already & I've yet to find it. I have a Sharp MD; MD-MT90 and I'm trying to suss out how to transfer tracks from my MD to my Mac. The Mac in question is a G3 powerpc with OS9.1 on it. I do have a digital cable that came with the MD, but thinking that's only really for CD-MD usage. The back of the mac had two usb ports and a couple of regular red/white sockets. What I want to know is; a- is it possible to transfer from MD - Mac. b- if so how & how easy c- do i need extra software and from where also, any experience on this from other users is a great pointer. As I've said I haven't seen (yet) any queries like this, so if this has been discussed before, whatever the outcome, could I be directed to it? Many thanks in advance for any help that may come. Best wishes, Frank
