Sony PlayStation MultiMode 3 (MM3) Modchip Install Guide

Sony PlayStation 10X PM-41 MultiMode 3 (MM3) Solder Map

On the PSone revision of PlayStation there is no external reset button for the reset signal to change the mode of the multi-mode modchip. For this reason it is wired to a voltage so the pin is not left floating. Whilst the PSone does not have a reset button, I wonder if there are any reset points on the board that no one has yet to bother locating due to the lack of an external button to change the mode.
