golden mask 6

[Smirnov-Arta]

Good afternoon, colleagues! Please help me!
Does anyone have a golden mask 6 scheme? (from 5 is not needed, there is another one).
The board is old, I want to restore full operation. Discrimination doesn't work.

I'll add it. maybe someone has at least a photo of the board from both sides in good quality, then it will also work!)

No. 6! Not 4 or 5.

Hello!). Look, no, that's not it. I have circuits and boards from both 4 and 5.
Everything is clear from them. But, the situation is as follows, there is a fee of 6 Masks.
Everything works except discrimination. And I can't figure out where to look, because it's different from 4 and 5.

Start the machine and take a picture of the display. I think I remember what it is made of.

Hi. You misunderstood. I don't need help setting up the MD, that's not the issue. Just a schematic or a photo of the board.
