All about the Roland Jupiter-series

Hi. I'm new here and was wondering if anyone knows if there are any 
copies of the user or service manual for a jupiter 4 anywhere on the 
web? (Or does anyone have a copy they could make?). I'm getting one 
tomorrow and know I have to do a few repairs on it. I know I will 
need a spare button and pitch bend wheel (the stick part is broken, 
not the wheel itself) to start with...
