# PU\-16 MM3 modchip installation diagram \- William Quade

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 video CD 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\. So they’re fairly rare\. Because of this I can’t find any MM3 installation diagrams for the system\.

Based on what I can find online the board most resembles the SCPH\-1000\. If you have one of these I’d look at MM3 diagrams for the SCPH\-1000 and other earlier boards and try to figure out where things go through trial and error\. In other words take a look at the PU\-7 and PU\-8 diagrams\.

Here’s a video about the console:
