This guide will show you how to install the switchboard for Cybdyn Systems PSIO flash cartridge in to a Sony PlayStation.
The guides here have a number of improvements over the official PSIO install guides by reducing the required steps for some of the console revisions such as less trace cuts, less solder mask removal, and alternative and improved solder points. PSIO are easy to install once simple tricks are learnt and followed.
