This board had the 3v battery lug islands, but no battery was ever installed (and it had R1 
and D2 installed )...

Indeed it did, On my Jupiter-8, I mainly use the 12db/oct setting...it sounds "harder", 
"nastier", "more rippin'", or what have you ... ;)

Interestingly no, the "Bend" slider, does nothing with the joystick unplugged...at least on 
this unit...I didn't see any other weird mods when I was doing the battery mod.

Thanks! I'll have a look at the circuit diagram, I assume its somewhere in the 'files" section 
and it has the pin numbers for the joystick...

Thanks for your help...bed time in Canada...<yawn> l8r
