Hi,
so today I dug out my old PS1 for some retro fun (quarantine got me). I opened it up in order to clean it a bit and I noticed that one of the modchip wires got loose and it's no longer soldered. I googled in order to find a soldering diagram for the chip and the board but I was not able to find anything. The closest thing I found is a MM3 soldering diagram but the solder points are not the same. I also don't recognize the chip at all. Does anyone know what kind of a modchip this is and where should I solder the loose wire? This is a SCPH-9002 PS1 and a PU23 board (pics are below). Thank you for your help.
