Audacity 
Downloaded Audacity for Windows; went to
Radio Shack The Source By Circut City and purchased a six foot mono-to-mono audio cable and a stereo-to-mono plug. I can now play tapes on my tape player and record them on Windows; then export them to MP3. (The mono is required because this unit has no line-in jack, and in any case I'm not recording stereo). This will do for now.
