Quantum Leap
Kreblog came through for me and found the answer to my query how can I convert my old cassette tapes to MP3s?

Using the Audacity software, an old Walkman, and a wire with dual miniplugs (one I happened to have stashed away in a bag of miscellaneous wires I hang on to for odd projects) I now have ripped some of my prized bootleg tapes.

Man, today is a great day.
