According to Wikipedia the PU-16 was only found in the SCPH-5903. This is a very unique board in that it was only released for the Asian market, and was only in a single model, and it was colored white instead of grey.

The SCPH-5903 is the only PS1 model that can play VCD movies. The system also has the RCA video plugs like the original SCPH-100x models did.

Apparently there were only around 10,000 of these made, and they were primarily in Hong Kong.

Installation tips

Here are some tips I have for you when you are soldering your chip into the PU-16.

• 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.
• Use a multimeter to probe around for alternative VCC and GND points closer to where you position your chip for a cleaner installation.
• Try to position your chip towards the middle of where all the wires need to go, to minimize wire length.
