V1 Messiah 2 USA Install Help
V1 Messiah 2 USA Install Help –
I'm new to the forum. I had almost given up on the messiah 2 that I had just bought because my V1 disassembly looked hopeless. Now that I know that the 4-pin connector must be desoldered, I have a few questions.
What type of desoldering braid and what dimension (.1", .05", or .03") to use to remove the 4-pin connnector?
Also, where can I buy the wires used to install the messiah2 chip? I'm having a heck of a time trying to find the right size wires here in the US. Thanks for your help.
you can get kynar and enamelled wire at radio shack
Is this the type of wire you are talking about? I've seen it Radio shack, but I thought it might not do the job.
How expensive is a desoldering pump?
that stuff will work for most connections. you will need 22-24awg wires for a few (gnd, pwr, etc.) tho..
You do not have to desolder the back side. Find a neo 2 diagram and use point #2 for the S signal. It works. I have done several this way, they were v2, but I imagine a v1 is the same. Unless the messiah is strange when it comes to that, because I have done it with Apple and magic 3 chips.
I'm not completely sure I understand your instructions. I've tried to find Neo2 diagrams with little success. Being an amateur at electronics, if it is at all possible, could you explain your suggestion clearer, perhaps with some diagrams? Also, I thought there are several wire connections that's necessary to be soldered on the other side of the Motherboard that cannot be accessed without taking apart the daughterboard. The 4-pin connector prevents the two boards from separating.
Correction about the alt Scex point (neo #2 point), it doesn't work for a V1. You can try, but it didn't work for me. PSX and DVD movies wouldn't boot right until I used the origonal scex point.
I used most of my supplies from Radio Shack. You would want the 30awg kynar wirewrap. Make sure to use a 15w iron with a 1mm tip or smaller. Also get some flux remover, I prefer the no-clean pen it's mess free . The flux pen I don't think RS sells those.
If you need help about the dissasembly of your PS2, mostly the part about getting to the other side where you desolder the power supply, you might want to check out my old post asking about that: http://www.ps2newz.net/forums/showth...&threadid=4240
By the way I used desolder braid to get rid of the solder around those 4 big pins. I don't really like that desolder pumb, if you are new to this kind of stuff you might mess up and end up with solder all over the board. The desolder braid is safe, and don't be afraid to use some force . Oh yeah, I used a 45W iron to desolder that. My 30W wasn't enough.
