Many of these systems have PM-41 boards inside, which is what this page covers. Some of the boards are PM-41 (2) and require you to use a different diagram. The model is printed on your board if you take apart your console. + +![PU-41](https://github.com/kalymos/PsNee/blob/master/images/motherboard/PM-41.png) + +### About the points +For models SCPH-101,SCPH-103, you can ignore the RESET. On the other hand, the model SCPH-102and SCPH-100, you will have to use the RESET point, and the BIOS points.All of the points are fairly easy to solder. + +### Installation tips +Here are some tips I have for you when you are soldering your chip into the PM-41. +* Cut your wires to be as short and direct as possible. +* You don’t need to connect pins one and two of the ATtinyX5 chip. Just desolder the wire. +* If you are using an ATtinyX5, or have a SCPH-101, then ignore pins A18 and D2. +* Use a multimeter to probe around for alternative VCC and GND points closer to where you position your chip for a cleaner installation. +* For the wires that go into the holes, or vias, of the board: it’s easiest to stick a small 30 AWG wire through the hole, then heat the wire and hole while adding solder. +* For DATA, be careful not to bridge solder to a nearby component, or knock the capacitor off the board. \ No newline at end of file
