You mean the tapes? You basically just hook up a tape player to your PC by running a 3.5mm M to M audio cable
from the headphone jack of your tape player to the line-in (or mic) port on your PC. After it's hooked up, hit record in your favorite audio program and then hit play on your tape player. There are guides online
to help you through the process (although I would avoid any "clean-up" steps).
