A 1.5k resistor included along with the Matrix PIC Fix chip, if you want a different value let me know. V9 V10 diagrams show 2k2

The Matrix Team - V12 Dead Syndrome Fix V2.0

- this now works on V9 / V10 ps2 phat models! it's a better protection method than the romeo fix which seems to make
the laser (in  non technical gabble) "a little bit shitty".  The surges that fry the laser are detected the console just powers off.


Quotes from original Matrix team documentation:



"The simple program will constantly monitor the communication between the mechanics controller and
the dvd controller. As soon as it detects a crash in the communication
it will turn off the pstwo to avoid any possibile damage to the coils."



"Install the 12c508 as from the schematics but connect
pin 4 to GND instead of point K. The pstwo should turn on when pressing reset
and turn itself off after three seconds. If this happens you can be sure that
the 12c508 is working and that the resistor value chosen is correct.
Disconnect pin 4 from GND and connect it to point K on the diagrams and you
are set to go."


"If you experience problems with the 1500 Ohm resistor, you can probably
safely increase it to 2000/2200 ohms."

"The usual installation care should be used when installing this fix.
Preferred position for placing the pic or the PCB is in the lower left
corner of the ps2 motherboard. Make sure that both a J and K wires run
parallel to the board and make them as short as possible."



"Last words : this fix can be used with or without the diode fix.
The diode fix can certainly increase the life span of your lens, and
should provide you with more time to realize that your ps2 crashed and
turn off the main power, should the pic chip fail to work. This has
not happened once so far in our test, but as usual the real results
will come from the thousands of pstwos out there."
