I'm sorry about being OT but there's an article in C'T 7/8 (Computer Technology a German mag) about how to make your own hardware mp3 decoder from old pc components. Very handy if you want to listen to mp3 files on your HIFI system. It's all explained in the mag and for schemo's you can look at: http://www.ieee.rwth-aachen.de/mp3/ Have fun, Paul
