This is the first full working prototype of a cdplayer, introduced in March 1979 by Joop van Tilburg in Eindhoven.
It has a small LED display and 4 buttons. It looks like it has a slide-button for searching and a 'auto'-search button. To the right it has a standby button and a play/stop button.




This is the first compact disc. It has a diameter of 11,5 centimeter and it is 1,1 millemeter thick. On the pictures to the right it shows Joop van Tilburg at the CD presentation.
