Everyone who was old enough to be listening to music pre-CD has a collection of grooved vinyl records and magnetized tape cassettes stashed somewhere. Those records are not only great for the cover art; some of them have music that still sounds great. Now there has been a concerted effort to develop the hardware and software to allow you to convert that music from its current analog form to digital, and reorganize it on a CD or an MP3 player.
First, of course, you’re going to need a turntable and/or a cassette player. You’ll be using a computer to convert your old music to digital format, so a cable that connects the turntable or cassette player to the PC (or Mac) is also in order. Apparently cables that have the old audio jacks at one end and a UBS connector at the other are relatively common and can be found in electronic emporiums such as Radio Shack.
Your computer will need to have a sound card – sound cards have been standard issue for PCs for some time. You may also need to incorporate an amplifier of some sort into the mix, as the turntable or the cassette player alone may not generate enough sound. That shouldn’t be too difficult...
