WM-FX12

The WM-FX12 is part of the simplest radio Walkman in Sony's 1992 FX range, pairing basic cassette playback with a built-in AM/FM tuner in an upright plastic body with belt clip and cassette window. It includes stereo/mono switching for FM, automatic tape-end shutoff, anti-rolling support, and a manual tape selector, but omitted Dolby, auto-reverse, and most of the sound-shaping features that appeared further up the line.

There is almost no performance here beyond "radio plus tape, done cleanly." And that is exactly what makes it useful. By the early 1990s, Sony had reached the point when a combined radio-cassette Walkman could exist as a very everyday object with no need to justify itself through novelty or complexity.
