PU-18 PsNee modchip installation diagram

This board was used with a wide range of consoles from the SCPH-5000’s, and SCPH-5500’s, to even some SCPH-7000’s and SCPH-7500’s.

About the points

For models SCPH-xxx1, SCPH-xxx2, all the points are on the back, and you can ignore the RESET. On the other hand, the model and SCPH_xxx0, you will have to use the RESET point, and the BIOS points. All of the points are fairly easy to solder to.

Installation tips

Here are some tips I have for you when you are soldering your chip into the PU-18.

• 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.
• A good place to put the chip is underneath where the legend is, towards the middle of everything.
• Use a multimeter to probe around for alternative VCC and GND points closer to where you position your chip for a cleaner installation.
