Patches and discussion for Ensoniq VFX family

hi there!
just bought a used SD-1 and am very pleased with it :-) before i 
start asking stupid questions at the newsgroup, is there a "digital" 
manual available for download somewhere? i know there's re-prints 
available in the US, but shipping (to germany) might take too long 
for such an impatient guy as i am :-)
thanks for your help!
