Towards the end of the SCPH-10x PSone production Sony revised the board slightly and released the PM-41 (2) board. This page covers the installation diagram for installing an MM3 chip into the PM-41 (2).

If your board has PM-41 printed on it then you should follow the PM-41 guide instead.

Installation tips

Here are some tips I have for you when you are soldering your chip into the PM-41 (2).

  • Cut your wires to be as short and direct as possible.
  • Pin 2, and 6 can be tricky. Don’t push on the components with your soldering iron or they might get knocked off the board. You can use tweezers to carefully solder them back on one side at a time, the orientation doesn’t matter.
  • Make sure the wires you are soldering don’t come into contact with other components or legs of chips.
