As a short term workaround, you can go or the 4.7K resistors.
But longer term, I would either find an original Poly joystick unit or go buy one like this http://www.p3america.com/pp/812.htm
And rig it up into your Poly. The joystick is definitely a performance control that you will want to have even if it is a crappy looking thing.

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... l8r
