Sony's first commercially available Walkman tape player based on the TCM-600 tape recorder with the record function omitted and a stereo circuit added. Features include two headphone jacks, and a "hot line" button that allows you to hear your surroundings, through a small mic with the music playing in the backgound. These units were pricey at around $300 US in 1979, and still can command a premium on Ebay for a decent one.
