Best Mod Chip...
I was told by a guy who installs PS-2 Mod chips, that the Messiah 2 Pro Play V1.33b, is more stable & reliable than the DMS3 V9. He said that he witnessed cases in which the installed DMS3 after some time, caused the PS-2 controller chip (where the wires P-W are soldered on), to burn.
Also, is it best to solder the P-W wires on the pins of the controller chip, or in the back of the PCB board that connects to the pins from the back?
As shown here:

Best Mod Chip & Installation
It looks easier to solder the wires P-W on the back of the board rather than onto the Controller pins, which are very thin & close to each other, but I've heard that soldering on the PCB board will cause damage to the controller chip after some time? So is it better to solder directly to the pins even though it?s riskier, or it wouldn?t make any difference?
Also, does it matter what type of solder I used? The one I have says: 60 / 40 Alloy, Dia 1.0mm.
My Soldering Iron is 15Watt with a very thin needle like tip. Will that also be ok?
Any feed back will be highly appreciated!
Thanks in advance.
that guy bullshitting you
Messiha is the worst chip for v9
Well retro, now you have both sides of the story. Your 'guy' says it's the best... while classact here thinks it's the worst.
Let's be honest here... it's neither. The latest code in the v1.33 is solid, based on all tests. It is by no means a crappy chip. Is it the 'be all and end all' that your guy says it is? Maybe not, but I wouldn't claim any other chip to be superior. Even the mighty DMS is having stability problems in the v9.
Just have to make your choice and live with it. Good luck.
But this doesn't quite answer the technical questions that I expressed, in order to deside which chip & how to install.
DMS is the best chip for features - if installed correctly but is a nightmare of instability if not installed 100% with short wires kept close to the MB, certain wires can not cross etc - or so I keep reading... never installed one yet as they are to expensive in Oz.
Not touched the Messiah2 since V1.30 which was a solid but expensive for what it was chip.
On the V9 I use the BlueX-5 and will shortly be testing the Apple3 and possibly the Matric MXL2 or their infinity when released.
On to the technical questions that the others ignored for their Fan boy type posts... ;)
Soldering to the chip legs is only better in the fact that you keep the wires shorter - and that is it. If it is beyond your skill level - do not attempt it - you will end up with shorts, and you will more than likely break legs off when trying to remove the shorts. or at least bend them sideways increasing the shorting problem.
If you lay the wires flat against the MB on both sides and solder to the VIAs you will also have no problems - even though the wires are longer.
The only danger is in scraping to hard on the vias when trying to expose the copper to solder to.
see here for help:
oh forgot to mention - the solder that you have is ok - but for fine work you would find it easier to use something smaller - I use 0.8mm for GND and power connections - and 0.35mm solder for all others - makes a smaller glob on the tip so less chances of accidental shorts.
0.56mm is also ok.
