You need either the Radio Shack PC interface cable 20-047 or the GRECOM USB cable. Both are, unfortunately, out of production and not available through any outlet that I could find. You might want to check with Radio Shack stores in your area, though, as one or more of them might still have the cable in stock. Another possible source is the PRO-97 owners group on Yahoo.com.
