Optrex 323 1867 display

Hi, I would like to try to play with Optrex 323 1867 (rebranded as KYDE 3232351) monochrome display (256x26 pixels).

I did not find any documentation about it. The only thing I found is Optrex 323 display:

As I understand it contains of 2 displays, each has 34pins and contains 128x26 pixels. For start I would like to control one of them. I have the board from which display was taken. It has single 32pin connector to which all display and button data flow go.

I have analyzed the board and identified which pins go through that connector:

Display pins -> (board connector) Meaning

 2 -> (30) GND
 3 -> (30) GND/Power +5V (One display goes to GND another to Power on this pin)
16 -> (30) GND
17 -> (26) Power +5V (with resistor 100 ohm)
18 -> ( 7) D0?
19 -> ( 8) D1?
20 -> ( 9) D2?
21 -> (10) D3?
22 -> (11) D4?
23 -> (12) D5?
24 -> (13) D6?
25 -> (14) D7?
26 -> (32)  ?  (with resistor 0 ohm)
27 -> (19)  ?  (with resistor 100 ohm and Capacitor to GND)
28 -> ( 5)  ?  (with resistor 100 ohm)
29 -> ( 6)  ?  (with resistor 100 ohm and Capacitor to GND)
30 -> (21)  ?  (with resistor 100 ohm and Capacitor to GND)

How could I identify these pins with "?" ? And how could I connect all these pins to Arduino?

Hi,
I have the same stereo and I am actually wanting to replace mine as my display has failed with the usual failure these see.
Where did you source your displays from?
Do you have multiple which you might want to sell one of?
I have found a few online but they are so expensive I cant justify paying that.
Thanks
