Discussion about the Korg PolySix synthesizer

Hi,

i strongly believe that on my KLM-367 the _Data_ Line from Connector CN1 
is defect and if i do a Traceroute from Pin2 DATA i see that he goes 
diretly to pin18 of the 8048=>is this correct? I ask because the wire 
ends UNDER the 8048 Socket.

If Pin18 of the 8048 is set to high (damaged or set to output) then it 
is clear that no data from the knobs can come into the processor. If i 
am right then is the Microcontroller responsible for Knob control and 
not the DAC...?!?!?

Greetings

Stef
