I had this extra DIS module and thought I would tear it apart. I was always curious what it looked like inside. There is less in there than I thought. It is completely encased in a gooey clear substance. It sorta feels like that stuff they use in magazines to attach those inserts. http://webpages.charter.net/lewishome/DIS/ ~William Lewis 95 mtx red 91+ white www.wclewis.com
