ONEchip is a Playstation modchip very similar in function to MM3, however this modchip is only for SCPH-102 consoles. It solves some issues which MM3 has with this particular model, allowing you to play backups and imports on your PSOne console.

Each chip comes with enough solder and 0.25mm insulated wire to install the chip. To complete the installation you will need a cross-head/phillip's screwdriver and a soldering iron.

OneChip is only compatible with the PAL SCPH-102 console. If you have a different type of console, you should use a different chip. Check out my PS1 Modchip Flow Chart if you're unsure of which chip you should use.

Soldering diagrams available here.

All my chips are stored on anti-static packaging.
