Jim,
thre is some info at:
http://www.box73.de/product_info.php?products_id=1869
it's all in German. If you can read that, goto "Zusaztinformationen" 
(additional informations) where you will find a comprehensive articel 
(pdf-document) also in German language (no I have not played with it).
enjoy Götz
