Discussion about the Korg PolySix synthesizer

Found this on the web:
 "The other test mode is started by jumpering pins DB7 and P17 using a diode (cathode towards DB7) on the
8049 processor on the KLM-366 circuit board (this can be done on the keyboard connector CN04). In this mode the
CV DAC is set to generate 0V, 2.5V, or 5V depending on the position of the OCTAVE switch (16’ results in 0V, etc.).
This mode is used to check the CV DAC and is not described in the service manual."
 
 
I wonder if this could be used to set up the antilog circuit?   Or possibly once in this mode, there are 
other voltage settings as well?  Think I will try this out.

Does anyone have access to a complete (!) Trident Mk II service manual?
Posting the procedure for the antilog calibration would help tremendously.

I have the calibration routines for:

Trident (Mk I) -> incorrect and partly implausible
Poly-61 -> will have to check
MonoPoly -> will have to check

Can anyone think of other Korg Polysynths from that era that might use the
same antilog technique? I think this is the list:

Polysix
Poly-61
MonoPoly
Trident
Trident Mk II

It would seem odd to me that all of them have an antilog calibration
routine except the Polysix. The Polysix also has a test point at the same
circuit position...
