Start by finding the line-in jack on your computer, and then you go to your local Radio Shack and drop $6.99 on an RCA-to-mini-stereo adapter, part #42-2551. It's got RCA plugs on one end and a 1/8" stereo plug on the other - attach the RCA plugs to your tape deck/record player/whatever, and plug the other end into the line-in jack on your computer. Make sure your recording software is configured to record from line-in and not mic, and you're good to go. If your tape player - or whatever you're recording from - doesn't have RCA outputs, you can get a male-to-male 1/8" stereo adapter cable, and plug one end into the headphone jacks on the tape player, and the other end to the line-in on your computer. Easy as pie ;)
Okay. Got it. I already have the RCA-to-mini-stereo adapter so I just may be good to go now. Thanks to both of you for your assistance!
