WM-AF48

The WM-AF48 is a radio cassette Walkman that combined FM and AM reception with auto-reverse playback inside a larger plastic body designed around simple, direct operation. It uses a manual tuner and basic transport controls, with the overall layout prioritizing cassette-and-radio practicality instead of sound processing, ruggedization, or miniaturization. This model was clearly meant to be easy to understand and easy to carry.

With the AF48, you can see how normalized the radio Walkman had become by 1989. This was no longer a special branch needing justification, but a standard portable format for everyday mixed listening. It was the kind of radio-and-tape machine that existed because Sony already knew people expected both.
