Your attitude is understandable, however this is precisely what this project is: a world class CD transport, made with components scavenged from a boombox. However, it's not just any boombox, and not just any modifications that make it work. And work it does, let me make this clear - some of the best implementations are only rivalled by the likes of CEC TL0. Hence the incredible popularity of this thread.
This was all based on a particular board, which is no longer available from any new boombox, and the original only rarely crops up on ebay. There was also a project to make our own, improved board, led by the user tvicol, but the group buy is over, and I'm not sure if he has any left for sale. Picking apart a random boombox and making a CD transport out of that will yield mediocre results at best, as expected.
