[sdiy] Korg 2069 AD Revisited

[Peter Snow]

Hi Duane,

I have a Korg EX800 which is the expander box for the Poly800.  However this thing runs off a 9V
wallwart so I am not sure if it uses the same voltages as the other synths you mention.  If you send
me the pinout of the 2069, I will try measuring at least the supply voltage.  I *could* simply
back-track from the chip to the power supply but all the important traces are on the bottom of the
circuit board and I do not really have time to take it apart. 

Cheers,

Peter
