good schematics for my archive... a content of it is 1.53 Gb now... by the way... THANKS. look also Surf PI schematic that is identical to this your Polish.
look at this attached schematic too.

good luck

Hi Yue Hailin.
Here is your circuit digram drawn with larger dots to be visible where has connection.
Pin 7 of US3 (LM741) and pin 7 of US5 (LM709) are connected to supply rail having increased (relative to battery) voltage. The increasing circuit is formed by US6 (ICL7660), D5, D6 and C17. The battery voltage 6V appears as intermediate supply voltage for US3 and US5.
For filtering of negative supply voltage, pin 4 of US3 and pin 4 of US5 are connected not direct to zero rail. The filter is formed by R30 and C21.

console

Slightly deviated from the topic. Scheme itself is not very interesting. Interested in console. I mean the device with an arrow (which is on video). There are practical ideas?
