jumper settings for GigaDesigns 1.3GHz 7457

Posted by: indibil on 2022-11-29 10:42:05 Hello, I recently purchased a G4 Cube upgrade card from GigaDesigns to 1.3GHz. When removing the heatsink I have seen that it has a 7457 at 1200. On the PCB, J1-J5 are used to select the CPU speed multiplier, I was able to find the PDF on google where it explains it, but I have been unable to find how to configure J6-J10, the red circle in the photo, which I suppose is It is used to adjust the voltage. Does anyone have the pdf of these jumpers? In a blue circle, would it be used to connect a fan? what would be the maximum stable speed for a 7457-1200? My idea would be to adapt this processor to a Quicksilver. Thanks.
