I've got some LPs I'd like to rip to my laptop computer but no stand-alone A-D converter.

I have a Sony DAT recorder in the same system as my turntable. My thought is to copy an LP to a DAT tape. Then hook the digital output of the DAT recorder up to the laptop and play the tape back. The Sony has the usual coax/optical out. But I don't know how to hook this up to my computer. Has anyone else tried something like this?

Thanks,

Andy
