KeyAssignerPinMap connections unclear #3
Description
First of all, thank you for sharing this!!
I have a Polysix with a faulty Keys Assigner CPU and I found your code here. Nice!!!
The big question is... how to connect the Arduino to the Polysix?
I found most of the pin names from "KeyAssignerPinMap - Arduino Mega 2560.xlsx" on the Polysix schematic on KLM366, but not all.
So the wiring inside the Polysix is not 100% clear to me. Is there any other resource than this file?
I'm assuming these pins to be connected to the Key Assigner CPU 8049 Socket
PIN1 - Switch - 8ft
PIN6 - ACKI (Arp Timing Interrupt)
PIN12..19 - PS Databus (DB)
PIN27..34 - PS PSENSE
PIN21 - "A" Addressing
PIN22 - "B" Addressing
PIN23 - "C" Addressing
PIN24 - Latch1
PIN35 - Latch2
PIN36 - INH
PIN37 - MC
PIN38 - ACKR
PIN39 - Switch - 4ft
What about these ones (do I need them at all?)
Ribbon Ref (to AREF)
Ribbon Wiper
From A6 (AREF is internally 35K to gnd)
Switch - Chord Mem (Porta)
Arp Reset
AudioIn (Analog Comparator)
Switch - Sustain Pedal
I2C SDA to DAC
I2C SCL to DAC
Switch Tape Enable (Tuning Mode)
Switch - From Tape (Toggle Cntrl Panel)
