Discussion about the Korg PolySix synthesizer

The data sheet for the DAC lists pin 1 as a no connect, so I don't think you have to connect it.

Made a mistake earlier referencing the two pins for IC 33 (the DAC), because of course, if you're looking at the board from below....

So, on the clone boards, Pins 1 & 2 are connected.

On my KLM-367, Pin 2 is connected to a smaller rail underneath the board, but Pin 1 isn't connected to anything...

Weird no?

No worries about the CPU, I'm taking as much care as I can, and I do have a spare one with code.

Something else I found while using the Logic Probe after searching the archives for 'Pulse Train', is that while going through CN10 - P1-14, I get pulses on all except Pin 5. This leads from a green wire to the Bank/Program board.

The KLM-367 traces for CN10 - P5 are ok.

Not sure if this is normal or not since the Banks are selected by Switches, nor what I should do here.
