Currently operational Pioneer 100-disc CD player (auto-changer type), model PD-F100, an older model. It works without any problems. There is no original remote control (you may be able to find one through an online search). You can use a Pioneer remote control from a different model (2 remotes included) or the buttons on the main panel, which is sufficient. You can set 25 music CDs in each of the four racks, for a total of 100 discs, and enjoy continuous full-auto playback.
