Should be able to dig up a fully functioning Sony Minidisk player. Owned and lost quite a few of them over the years. Damn things were sleek and small, but they meant the world to me. Napster and then Limewire provided the mp3s thanks to the old 56k dialup modem, then a mini jack connection from PC to the Minidisk. It took a hell of a long time to get everything set up just so, but it was worth it. Every time.
