What's the deal with the "S" point for V1-3 PS2's?
What's the deal with the "S" point for V1-3 PS2's? –
Okay I'm getting my Messiah2 soon, but I always research everything beforehand so the install will be much easier. Well the "S" (Scex) point is confusing me. In the pictures it just points to one solder point on the motherboard, but other modchip install diagrams which use the same point say something else. One I found stated that the point is in between the mainboard, huh? I'm not sure what it meant so I searched the forum, didn't get anything informative as the search engine only allows 3 characters+, so a search for "S point" won't do. Didn't get anything either for Scex. Anyway could you guys please explain what the deal is with the "S Point".
While reasearching I found good info on the alternate "S Point" which is on the bottom of the mainboard. Seen some success, and easy to solder too. How is it working out for all you who tried it, did you have to switch to the origonal point?
Oh and one other thing I would like to ask. Let's say I'll end up using the alternate "S point" on the bottom of the mainboard, that will leave only the CLK solder point on the top of the mainboard? Is there any alternate CLK solder point on the bottom of the V1-3 mainboard? I'm asking this because if I can, I might aswell solder everything to the bottom of the mainboard and not risk damaging the cables when disconnecting/reconnecting them when taking out the mainboard so I can solder to the top of it.
I don't recommend install anything on v1, v2 and v3 consoles. The installation is for professionals only (a true nightmare).
The motive is for B, C, D, E, F, G, H, I points. About Scex point is just near of resistor, there you'll find a "ready point", without any component on it. Isn't hard to find, messiah1 diagrams are pretty clear. BUT you'll need to dismount completly your console, in order to get access just for this damn point. And for v1, v2 and v3 you'll find a "nice" 4 points connected (soldered) on power supply, you'll need a 60W~80W soldering iron in order to desolder these points.
I give up completly all my installations for these old and retired consoles. A true nightmare indeed.
PS: I got v1 to install yesterday, boy, nevermore again!
You have to be careful about alternate points. If they have electrical zero resistance, then fine; if not, it'll be because the alternate sits on the other side of a resistor or such like. In that case, more current will be required to drive the signal and that may have unwanted knockon effects.
My advice is to stick with the published points.
Yea...I have to agree...never again on a V1. I got the launch version....installed the Magic 3....working just GREAT!
If you don't plan to play PS1 backups....no need to solder the "S" point.
S Point Not needed if not going to play PS1?

Have you verified that the S point doesn't really need to be connected to the chip if you're not going to play PS1 backups? Hmmm... maybe I don't have to solder the S point. I already have a Neo 2.2 modchip. I wonder if I can use that instead of the Magic 3 if I wanna play PS1 backups.
Contrary to popular belief, I believe charlie_ps2 has stated before that the S point is actually necessary for all games with the Messiah2...not just for PS1 games as some would think. And by the way, I do have a v3 console in which I installed a Messiah 2. Works GREAT!!!! v3 consoles don't have the 4 power points as in the earlier versions so it is actually rather easy to disassemble to get the other side.
I have taken apart v1-2. After the 3rd time I have no prob. with working on any of the v1-2's. The 4 points connected (soldered) on power supply. After takeing them off once they are very easy to get off after that. you'll need a 60W~80W soldering iron in order to desolder these points. As for all the small points to connect to, they are a pain. But if you can do it once then you can do it as many times as you want. Just like rideing a bike. Gets easer & easer everytime you do one.
well terry at foundmy.com confirms that using the alt-scex and alt-CLK on his diagrams m2 pro has worked no problems, no reported booting issues. well so far.
pictures are up there.
