This is my first modchip installation, it is a crystal chip v1.1 into a SCPH-75001a(GH-040-12) PS2. After soldering about half of the pins, I realized the version 14 diagram provided by mod-chip.com was not the same motherboard as mine. So I was pretty upset about that. Is there a pin diagram for installing the CC1.1 on a 75001a? I found a picture of someone else's install I've been trying to use. Also.. I'm having so much trouble with the VIA's that I've almost given up, I have heard you are supposed to scrape off a little bit.. and possibly use flux?.. Before I go through all of the trouble doing doing these horribly hard pins, I was wondering if I could disconnect the power wires to the modchip and test to make sure the ps2 still works?
