The player that put a whole album in your coat pocket, as long as you didn't run. This Sony Discman D-145 from 1995 is rebuilt from its service manual and photos of a real one, with a CD of twelve 90s dance tracks written for the museum (turn your sound on). ▶II plays and pauses, ■ stops, and the skip keys change track or, held down, search. PLAY MODE steps through one track, shuffle, the first 15 seconds of each track and a programme of your own; REPEAT/ENTER repeats, or picks the tracks. Drag the ribbed wheel on the front edge for the volume. OPEN pops the lid so you can lift the disc out, and pressing the lid shuts it. BASS BOOST and AVLS are on the right side, HOLD on the front and RESUME on the left, and fresh batteries go in underneath. On a computer, Space plays and pauses, S stops, the arrow keys skip, M and R are the mode keys, + and - set the volume and O opens the lid.
