Just found one while cleaning out some drawers. Don't know much about these things, but trying to get some expert thoughts. It does have the power cord, but nothing else.
Great find, those Denon Units were high-quality and not very common. A lot of those suffer from non-use, the sliding parts "freeze" up and they have to be opened, cleaned and relubed. They may be belt driven but I'm not sure. Since these are on the nicer side of portable CD players, I wouldn't use it as an everyday unit, I'd hook it up to an existing stereo and use it as the CD source. Our member Jorge found one a couple years ago, here's his thread, he loves the portable CD players and does a great job restoring them. http://stereo2go.com/forums/threads/denon-dcp-100-my-dream-discman.4805/
