Remember your old Atari? The one you played Frogger and Donkey Kong on for hours. Unless your mother donated it to Goodwill when you went to college, it's probably hanging out in a box somewhere in your parents' house, right along with your eight-track player that's just waiting for you to pop in that Billy Joel tape you loved. If your household is anything like ours, there isn't a cassette player to be found. So, if you want to listen to your old mixed tapes, your parents may still have your gear.
