I am not certain whether this one has ever circulated before. A few years ago I helped Rick Lopez with a cassette -> CDR transfer project of a bunch of old cassettes he had in his collection.
This is one of the cassettes I transferred for him, but the best I can tell I never shared it with anyone else in the past.
