Comsoft & Albert FIX VIII (2)

[comsoft]

Just a minor change that i think had to be made :D
Already installed it and works perfectly. :dance:

here some info:

This fix is based on the IDEA of MATRIX TEAM PIC FIX
And on the previus version of Comsoft & Albert 35

coded by XcalibEr aka Comsoft on 19/02/2005

change from version III
On version III the TEST was active if during the first second the tray opend.
In this version the TEST mode will be active ONLY if the pstwo boot and TRAY is OPEN at the same moment.

the following changes has been done from Ver II:

1. the pic will shutdown RS2400FS a 1.5 second from boot regardless of the state of the TRAY - WHEN INT IS FAILD!!!
2. the Test mode (tray open) will shutdown the pstwo a 1 second from boot (not instently as before).

explenation on how the PIC Fix works:

1. if on boot TRAY is open enters to TEST mode.
2. wait 1 second for pstwo to finish initiation.
3. if in TEST mode it does IMIDIATE SHUTDOWN PSTOW.
this is anables to check in anytime needed if the PIC/FIX is working.
4. checks for INT for every 250ms at anytime if INT is HIGH (which means it's ok and the mechanics controller is not in deadlock)
the PIC code jump to WATCHDOG routine.
5. if 1.5 second from boot have passed and the INT is still not active then the PIC CODE mute the RS2400FS (CD/DVD DRIVER)
and by that disable any current flow to the lens and to the CD/DVD motors.
6. if 3 seconds from boot have passed the PIC CODE shutdown the pstwo to save the lens.

WATCHDOG ROUTINE:
1. the PIC CODE check the INT line for every 1ms.
2. if the INT line FAILD (INT == LOW) for 50ms then the PIC CODE MUTE the RS2400FS CD/DVD DRIVER.
if after that the INT line return to be active (INT == HIGH) then the PIC CODE return the RS2400FS CD/DVD driver to active mode
and everything is back to normal and the user don't even know abot this.
3. if a 200 ms have passed and the INT line is still not active , this means MECHANICS CONTROLLER is in deadlock , and pstwo
is shutdown.


we take no responsebility what-so-ever for using this code/pic.

any suggestions/remarks please send to comsoft@cso.co.il

hope one will decide to make this pic on a PCB so all can enjoy it :-)

installation diagrams can be found here! (http://www.console.ombouw.com/v12/protectivecircuit.asp)

Can please post the full modification + diagrams + code +++ in one section coz i lost you.

Thanks

u absolutly rignt.
here i've fix it. :D

[d3dv12]

a simple diagram, caps removed, chip legs pic508 what resisters,digram ps2 show pionts

alot more would try test use the code, u get feedback u want much easier

at moment yes some can work it out but to much hassle for most to worry about, summone has clear easy diagram

would only take u 2 mins :chinscrat

[92GTA]

When will you have a pcb out that we can just buy and solder in?

so u work extra 20-30 minuts, and u get a bulletproof protection.

if someone fix is u'r ultimate solution why u'r serching for a new one??
there is no fix easier to install then the someone fix, so stay with it.

my fix is differ from somone fix by attacking the problem not the simptoms.

someone fix will save u'r lens when a stress of high current flow through them, but i don't know for how long (few seconds maby).

but my fix attacks the problem which cose this situation for the first place.

my fix can last in a crashed state for hours B)
plus i met someone new on msn today who installed 200pstwos and no probs :P


face it - this solution is simple because it is only one flaw in the pstwo, not some software protection...
a modchip on the other hand cant be simple because it has to overcome protection.


I have no problem with your fix and it is nice that you find so much joy in it.
-but face it already- mine works!

get a life and wake up, i not search or want your solution
ps diodes matrix pic i got no dead ciols,none, but 3 dead laSER ALL READ CD NOT DVD

SUMMONE FIX, not 1 dead ciol, no returns at all, but i seen few reports dead lasers that will only read cd

my hope was your fix would stop the later problem


now to me it seems quite obvious , u want your name remembered as solver of the v12 problem, to do this u need to make your solution as simple to understand as possible, if not it get shoved under the carpet asnd forgot about

:rant:

[T07N]

Come on guys, this is not right. Comsoft and Albert are just putting there fix out there. They have nothing to gain, they just want to help the scene. Also, this is based on the Matrix Pic Fix. From what I've read on here, the Matrix Pic Fix and Summ0ne's fix are highly recommended. Comsoft and Albert's fix is an improve version of the Matrix Pic Fix, I would not doubt its potential.

[mikearama]

There's plenty of room for fixes on the scene, no doubt.

My only wish is that the politiking (sp?) would end... it's crap. Statements like:

my fix is different from somm0ne fix by attacking the problem not the symptoms.

For that to be true, your fix would have to prevent mechacon crashes. How do you figure it does that?

All fixes, as far as I can see, respond to a crash. I get the impression from all accounts that summ0ne's fix does the job, as does yours, comsoft. So why the postulating?

[saasf]

i'm just happy they didn't start selling it and released it to the scene. i haven't had a chance to try ur pic fix but i will when i get some more pic's in. i recommand the matrix pic fix with summ0ne's fix and seeing how urs is improved code it can only get better :) .
hope to try it out when i can and will report on how the fix goes.

cheers

Hell i didn't say ur fix is not good, stop being protective :)
I my self installed couple of pstwos with combination of our two fixes (bullet proof solution if u ask me).

my question is that. u'r fix seem to be working from what i read on the scene. but did u really tested to see how long on mechanics controller lockup takes the pstwo to fry the lens???

cose if it takes the user too much time to pull the plag off i think the laser will die.

my fix will stop any current to the laser 50ms after INT not responding. so i think at this period of time no damage will happen to the lens even without any additional fix to the lens.

there is something in u'r saying :)
but i ment: problem = mechanics contoller lockup. solution = stop current to lens and if still lockup shutdown pstwo. better solution the letting the user pull the plag.

summone fix:
problem accure, simptom == high current through coils. solution = resistor to rute the current.

so the combination of the two will be bullet proof if u ask me.

think of this: a PCB with our pic and summone resistor on tracking and albert capacitors on focus. the best fix ever.

PLEASE SOMEONE MAKE THIS FIX ON PCB :-pray:

what's u'r contribution to the scene?? eccept dropping down on oher ppl hard work?

[d3dv12]

what's u'r contribution to the scene?? eccept dropping down on oher ppl hard work?

ive never dissed your work, just said simple diagram make it much more accessible to the public, in no way have i ever attacked u or your solution

seriously
once again thx for your work ;)


as for my contributions to scene , a fair bit more then u are aware of obviously, but i not after fame never have been :dance:

ps if u like to discuss my contribution in private try the pm

[mikearama]

That would be sweet indeed. I'd actually be very content with just the summ0ne resistor fix and your pic fix. Even that would be elite. You guys should hook up on that.

[comsoft]

ps if u like to discuss my contribution in private try the pm

why u think i do it for fame? :chinscrat what does this so called fame give me?

if i wasn't really belive in my fix then why would i waist my time on it making improvments,testing it , and so?

if i really was thinking of sommone fix to be the ultimate answer to the problem then i would install only it and make my life easyer.

HELL I COULD BE WRONG AND SUMMONE FIX COULD BE EASY AND WORKING AS THE ROMEO FIX!! BUT AS LONG AS I'M NOT SURE ABOUT IT, AND SUMMONE CAN'T BE SURE EATHER, I'M TRAYING FO FIND A BETTER SOLUTION AS WE ALL HAVE TOO!!!

sommone make a great fix by making it as simple as possible, and that is amaizing. the guy know electronics for sure.

I'm seeing it from the programming side as a programmer my self, and my logic says "since mechanics controler lockup is dangouress to the lens, don't relay on user to shutdown console, let the pic do it...."

and the most amaizing think in our pic is the ability to SHUTDOWN ANY CURRENT FLOW TO THE CD/DVD device.

so i was thinking a combination of our two fixes will save the lens like this:

1. when mechanics controller lockup the resistor of summone will rute the current.
2. when pic suspect of controller lockup after 50ms it disable any current to the CD/DVD (no need for summone fix here)
3. when pic KNOW mechanics controller is lockup shutdown pstwo - INSTED OF USER PULLOUT CABLE.

[summ0ne]

i can make pcbs for 1$ a piece incl the resistors.

all i need is some serious buyers.

so comsoft, if u can provide pre-programmed PICs with your code....

minimum batch = 1000

[modarea]

Comsoft, Summone,

Here is the result of your work.

I put both protection into the v12b.

Thanks for your hard work


To program the pic: build a JDM programmer and use IC-prog

[comsoft]

Reall clean and nice work :)

minimum 1000 .. wow how am i gonna progamm them one by one :rolleyes:
is there an easy way ? is there any chinees factory that can do that??

i bet in the factory thay can program 1000 pcs at once :D
i never had the chance of doing that, but if someone here know how do to it , cheap and fast please help.

in here (israel) thay want 3.15$ for each PCB including the components soldering.

1000 pcs is still a small quantity, so u have to do it by hand :(

i already have experience in making these pcbs:
http://subzero-chip.com

for 1000pcs and all components robotically soldered on cheap single-side quicksolder PCBs i can reach a price around 1$, not including PIC price.

how long does it take u to program 1?
make the icprog go as fast as possible, verify during programming - it usually zooms thru the addresses where there is no code.

for my SubZero 2 chips i pay my classmates below 3EUR/h and they program 30-40/h. i bet a PIC with short code takes less time to program then a SX.

In china they have cheap labour... here i have cheap students ;)

[d3dv12]

why u think i do it for fame? :chinscrat what does this so called fame give me? nothing really buit its the truth u want me post u a link of u saying it????????????


if i wasn't really belive in my fix then why would i waist my time on it making improvments,testing it , and so? were this come from i never said anything against your fix, apart from take 2 mins to make a simplified diagram

if i really was thinking of sommone fix to be the ultimate answer to the problem then i would install only it and make my life easyer. lol lreread from were this started u talking from your ass

HELL I COULD BE WRONG AND SUMMONE FIX COULD BE EASY AND WORKING AS THE ROMEO FIX!! BUT AS LONG AS I'M NOT SURE ABOUT IT, AND SUMMONE CAN'T BE SURE EATHER, I'M TRAYING FO FIND A BETTER SOLUTION AS WE ALL HAVE TOO!!! agreed ive never disagreed

sommone make a great fix by making it as simple as possible, and that is amaizing. the guy know electronics for sure. yes

3. when pic KNOW mechanics controller is lockup shutdown pstwo - INSTED OF USER PULLOUT CABLE.

i couldnt agree more

all i ever said was people would appreciate a simplified install diagram

u not going on about what i have done for the scene any more, maybe u have done a bit of homework
as i asked before this bitching is getting people no were, reread u see i never wanted this i just made a simple suggestion that i thought would help the public greatly

if u want to carry on bitching surely its better u pm or email??????????

[bobcat]

so hopfully we should see a new fix on the market in the next couple of months hope you 2 do it.

[comsoft]

i couldnt agree more

all i ever said was people would appreciate a simplified install diagram
i'm agree with that. i my self don't use SMD components for the installation, but i don't have high qality digital camera to photo my installation. so if u wan't u can make one and contribute ;)

u not going on about what i have done for the scene any more, maybe u have done a bit of homework

No i didn't do any homework and actully i don't care. i'm not into competition who is more contributing to the scene, but i'm not into flame fight either.

as i asked before this bitching is getting people no were, reread u see i never wanted this i just made a simple suggestion that i thought would help the public greatly

i'm always open into suggestions, but u'r message was more into flaming then sujjesting anything.

if u want to carry on bitching surely its better u pm or email??????????
I wasn't the one who did the bitching, all i did was releasing my fix and pointing on weak point that summone fix has in a way of finding a perfect solution which i think it achived by the combination of both fixes!!!

good day,

[gee-man]

A number of supply chain vendors (eg, Avnet) will sell chips by the rail that are preprogrammed with your code. Microchip even does this directly, but you have to order many chips at a time.

comsoft - use my code ;) It works and it protects the console from the moment you power it on, instead of waiting 1.5 seconds. I've tested yours and it works too, but I haven't figured out how to deliberately cause a mechacon crash yet.

I haven't tested either of our code on the V12 yet... My unmodded, unopened V12 is now in the hands of Sony for warranty work... I left GTA:SA paused, went to the kitchen to cook supper. Later I smelled something that wasn't food, and found that my V12 had shit itself. It even left black soot on my GTA:SA disc... Perhaps Sony should start summ0ning its consoles from the factory.

I thought about disabling RS2400RS after 50ms of inactivity after the 1sec dealy.

I've based my code on matrix idea and albert finding when he connected the INT line to the digital analizer. and if i remeber correctly on the first second of initioation there is no communication on the INT line (correct me if i'm wrong).

anyway right now it mute the RS2400FS after 1.5 second from boot. and since the 1 second is just used to init the ps2, then there is no risk to the lens on this period of time.

the only question is do i need to reduce the 500ms to 50ms insted??!!
any idea apritioated.

any idea apritioated.
If the PIC mutes the RS2004FS when it first turns on, there's no problem. I'm thinking there's the possibility there could be a mechacon crash right away when you turn the playstation on, so your first 1.5 seconds could be 1.5 seconds of coil burn.

Use the T0CKI trick that I'm using in my code to do the 50ms thing. Use the timer hardware to count INT pulses instead of making your software poll the line.

[comsoft]

From my testings the mechanic contoller start when the ps2 is READING a disk and/or traying to patch the bios lines.

i don't think it's a good idea to right on boot mute the RS2400FS since the ps2 init the lens and move it to it's parking position.

maby i can reduce the INT FAIL delay on boot from 500ms to 50ms and see if it's working fine.

someone here before sayed that he knows the neoasic group and say he can speak with them to produce the fix.

well, i would love to buy my self.

[Robot]

i think the whole scene would like to buy :)

[comsoft]

just an idea. but the one who got the means of making chip pcb's can make a winning combination of our fix with summone fix and he can make lot of money by selling it.

just a thought.

[summ0ne]

Hey, i am just wondering:

How many of your fixes or pic fixes did everyone install without any other fix?

there might be something on this:chinscrat

[gee-man]

do you really need a PCB for this? just use a 12C508 in a DIP package with the leads bent sideways, just like almost every PS1 modchip ever made...

Presolder some wires and a decoupling capacitor to the PIC, and you've got a full fix ready to install. Just glue it to the board somewhere and wire it up.

[Robot]

People like to buy PCB's :)

[modarea]

Here is my work on the pcb and diy version:

You can download all the files at:
http://www.mod-area.com/tutorials_e.html

Please communicate with us: info@mod-area.com if you wanna buy pcb or diy kit.
I spoke with Comsoft about the possibility to sale the PCB complete and he was OK with that
Summone, if you agree, I could also put resistor to make a complete package for lens protection
I will try to make a price list and keep the price reasonnable.

The PCB version is full with the PCB design so you can also make it yourself.
For those who don't have a PIC programmer, I can suppy the kit.

Don't forget, this is the work of Comsoft, I only did the PCB layout and the diagrams.

[comsoft]

Hey, i am just wondering:

why u do that?
I'm not getting down on u'r fixes, and i have respect for u'r work. so lern to repect others.

I myself installed alot of console with only the pic fix and i have faith on that fix not becose i wrote it, becose i know it can protect agains mechanics contoll lockup situation.

do u really belive that i didn't install my fix until now?
I know it's possible to install it that way. but if it was on pcb then it coult be a brieff to install :p

http://pulz.no/ps2/slimfix.3.jpg (The picture of the fix i got)


I just got the same thing and here's the info they released with it

Slim fix v.3 is the new version of the v12 fix ,it is build in the latest hex code to protect the 7000x lens, and works much better than others.

All fixes on the internet with regulators current limiters and diode fixes are not working so accurate as this one because they only limit the current a little and time will kill you're coils at the end.
This protection circuit will totally shut down the output channels of the RS2004FS the moment MECHANICS CONTROLLER or DSP crash, fail ore whatever.
If mechanics controller or DSP will crash during play this laser protection circuit responds in less than 50ms and put RS2004FS in mute mode so all output channels are shut down and current thru you're laser will be 0 (zero, nada nopes). If the error state of mechanics controller or DSP continuous for more than 200ms the PStwo will shut down.

To test if you're protection circuit is working put you're PStwo in standby mode open the top cover and press the reset button you're PStwo will not switch on. If it switches on there is something wrong installed

This protective circuit is done by COMSOFT (aka XcalibEr) and Albert35,thank you for their best work

[modarea]

Hey Comsoft,

The PCB is done using press n'peel and are done in my lab. It's home made
I do not have enought order for producing pcb.

Yes the PCB comes complete and tested. You just have to solder the wires.

I know what u mean, i use this method my self :)
but how u gonna make 100 pcs if someone will order from u, it's a heall of a work :)

good luck

[SDU101]

Have anyone check ps2ownz.com? Seems someone has released a PCB of comsoft's work.

[comsoft]

Yea.. our fix is on a PCB great.
I hope with the latest code :)

where i can order it from :)
coooooooooooooooollll

thank to who made it possible :)

[cakcetin]

Hey Comsoft here your fix.They are say very thanks to you and to albert35...
Can you check here:
http://www.i-c.bz/slim-fix.v.3.htm

[comsoft]

Thanks man.
I've emaild them. now the fix installation will be much faster :)

[BST Console]

I wonder if its the latest code in these pcb fixs.

[cakcetin]

I hope latest firmware inside this fix now we can do it summone fix and your fix= Maximum protection....
:)

[comsoft]

That's for sure :)

[comsoft]

I wonder if its the latest code in these pcb fixs.

If it's not , u allways can add sommone fix and u get max protection.
Now with the pcb in hand the installation is a brief :)

[brywalker]

Now the trick is....where can we buy it?

[comsoft]

Thay sending my some samples :)
and i'm ordering 100 pcs :)
COOLL..

brywalker: the link to the resseller site is on the previus page.

[modarea]

Comsoft,

I know that it's a lot of work.
Don't forget, it's to help people out there. Anyway, all the documentation is available.

By the way, I ask a quote in Hong-Kong and for 100pcs, it's 3$ per unit.
They don't tell me about the revision code.

Thanks

[Robot]

sounds expensive. I will be maybe going to china soon, i will get maybe 1000 pcs made. Then it will be cheap

may the force be with u :)

[flashharry]

would be even better if both fixes could be put on 1 pcb then i can be lazy & still sleep at night

[comsoft]

Yea, thats for sure. but our fix is more then enough.

[comsoft]

Couple of minuts ago my fix saved my pstwo :)
Right after booting, the game started to load and suddenly the pstow shutdown.

reboot and everything is find, no harm done! :)

[davbere]

Good work Comsoft.
I cant wait to try your fix.
Could you tell me where I can order the pcb at a reasonable price ?

Thanks David.

I don't know. i've asked them about it and didn't got respond yet :(


well i was quoted price but would only order the latest version as the shipping price alone was nearly 40 usd to the uk...would be happy to pay if it was the latest version

[comsoft]

Don't worry, i've contact them, and gave them some ideas for changes.
Thay've told me that thay'll produce with the improvments i adviced :)

thay have opend mind :)

I just got in my first 25 of the new PCB version of this fix. Ill be installing all 25 this week for testing. I was told that they were switching to a white PCB, on the next batch, but these are green. They have the wires pre-attached and there is a layer of sticky-film on the back side covered by wax paper. Much like the Duo2SE, Messiah2 etc. Ive get some pictures that I will be uploading. Cross your fingers for me.

edited to say-->
Ive done 3 of these now. They seem to work. They DO cut the power off until the lid is closed. It took me under 2 mins to install these. Ill be installing the other 22 over the next few days.

[comsoft]

can u tell me if it's imiddiate shutdown on test mode or it takes a second to shutdown?
on the last version of the code it take 1 second to shutdown on test mode!!!

[BST Console]

If you mean by timing the green to red light....it is about 3/4 of a sec by my guess. It is Green for a little less than a second

[comsoft]

if it's turning on and off so fast that it's a small blink then it's the old version.
if it's turning on for a second and then off then it's v3 or v3.2

[BST Console]

well, Id say its more than a blink for sure

[comsoft]

It seems like the new version :)

how come u got u'rs before me :(

[comsoft]

A new production of our fix is release and can be found on neoasic website.
this version uses the old code but has combines with a diode fix for extra protection.
forthermore the fix is has a spacial shape for very easy installasion. :)

2005.03.18 >>> New Slim Fix released ~ Another PStwo Slim Fix sample arrived us for survey.

We just received the new slim fix board for survey. It is a special PCB design with one PIC and 4 pcs of diode for protection all PS2 SCPH-700XX console. The new fix is the same function to slim fix VIII ( based on the idea of Matrix-FIX and on the previus version of Comsoft & Albert 35 ) It must cut 1 wire of PStwo mainboard and solder 6 wires when you installed. Anyway, we will test the new fix on all V12 console with different mod-chip and post the review recently. All the fix functions as following :

1. On boot the pic of the fix waits 1 second for the pstwo to initiate.
2. Check to see if the CD Tray is open, it does IMIDIATE SHUTDOWN PSTwo.
( This is the test mode, which enables to check in anytime if the fix is working )
3. Checks for INT for every 250ms at anytime if INT is high, the pic code jump to watchdog routine.
4. If 1.5 second from boot have passed and the INT is still not active then the PIC CODE mute the
RS2400FS and by that disable any current flow to the lens and to the CD/DVD motors.
5. If 3 seconds from boot have passed the PIC CODE shutdown the pstwo to save the lens.
6. Clip the input tracking signal from the CD/DVD controller to 1.2 voltage (more stable and safe)



well now the world is safest place to mod :)

[brywalker]

Not to flame here, but I thought you wouldn't need any more protection than the PIC. Also, I thought the diodes didn't even help.

[BST Console]

I have to agree, Im not sure why anyone still thinks the diodes are a good idea.

But just so everyone knows, These V3 pcb fixes work like a charm, I had one save a pstwo today! I just ordered 50 more ( I used up all 25 of them that I got in this week)

[cakcetin]

Because when use diode they not need more pcb for 683 or 303 becasue they are only need cheap,simply and only one PCB
I hate from all cheapest idea!!!!

[comsoft]

That's cool man :)

I think i'll do more improvment to the code. i had an idea and i'll test it sunday :)

[comsoft]

Not to flame here, but I thought you wouldn't need any more protection than the PIC. Also, I thought the diodes didn't even help.

U'r not flaming :)

that's right, the pic is enough.
I didn't produce this fix, thay did it by them self and decided to put the diode fix as well.

I know the diode fix alone don't worth much , since thay only delay the coils burn process nothing more.

but since thay used the old code insted of the new one, the diodes can help when a crash will happen immidiate on burn while the old code is at 3 sec delay.

the new code is muting the RS2400FS 1.5 second from boot when problems accure. (1 sec is dealy and after that if there is 500 ms of inactivity on the int line it mute the RS3400FS).

I think i'm gonna improve the code a bit more in a way that it will mute the RS2400FS right from the begining (just to make extra shure) and reactive it just when INT is active :)
:chinscrat

[fatcat]

The attached picture shows how I currently wire up the Comsoft PIC chip with the v3.2 code and the resistors, I do not use a PCB, just wire resistors directly to the PIC chip. I do not fit the 27nF capacitors and I also only add the Summone resistor fix on the Tracking cct. As Comsoft stated his PIC should be enough but I install the tracking resistor as a piece of mind. I used to fit the resistor to the Focus cct but had to remove them to often due to read problems.

It does not take me long to fit the fix and I am not stuck buying the PCB's with old code etc. Once the code as settled down and I will look at buying the PCB solutions. I suppose I could buy the boards and remove and fit update chip with the newer revisions of the code.

I use to use the Matrix diode fix, then the Matrix PIC fix, then the Matrix PIC fic and the Summone fix and now I only use the Comsoft fix and the Summone fix (Tracking only).

I have never experienced a console lock up, so I can not give an opinion if it has saved a console from damage yet. But I always install the Laser fixes first and then ensure that the console resets correctly as per Comsoft test procedure and then finally fit the modchip.

Modarea: Where about did you buy your SOIC zif socket for programming the 12C508A SM part. I can only buy the SOIC zif socket for SN part locally over in my part of the world. I currently use the 12C508A with std DIP package but have to sanded down the top and bottom to reduce the profile of the PIC to get a nice fit between the board and bottom plate.

On a side note does it matter if the resistors are the 1206 or 0805 series? I am currently using the 1206 series due to there higher wattage rating.

[comsoft]

Thats looks cool man.

[orangpelupa]

can i know the price of the PCB fix, i think this the best fix on ever made. i need it 4 my pstwo

[comsoft]

No d1v1ne0 china also selling it :)

Is the SumOne resistor needed with this fix?(I mean does it make any difference if you apply one?)

[BST Console]

Ive been applying the summ0ne fix along side of the c/a35 fix. Works like a charm

[comsoft]

Is the SumOne resistor needed with this fix?(I mean does it make any difference if you apply one?)

U don't need to apply any additional fixes with this one.

u don't need to reduce the current flowing the coils since the fix will shutdown any current to the coils and dvd motors after 50ms of mechanics contoller lockup.

[comsoft]

I just had this great idea of improbing the code in a way to reduce the number of wires to 4/5 and add a more complicated test that will tell the installer it the chip is installed correctly.

[comsoft]

Comsoft FIX V4 is ready :)
Now for live testing :)

[cakcetin]

Evolotion is perfect comsoft....Looks like xecuter chips:)

[comsoft]

Tested it and it works fine. have videos to show but can't upload them :(

[davbere]

U don't need to apply any additional fixes with this one.

u don't need to reduce the current flowing the coils since the fix will shutdown any current to the coils and dvd motors after 50ms of mechanics contoller lockup.

Is Mechanon lockup the only time current increases to the coils ?
Or does it spike for other reasons as well ?

[comsoft]

Current is increases in two cases:

1. use of non quality media.
2. mechanics conroller crash..

but in the second case it's FATAL and immidiatly kills the lens :mad:

[fatcat]

What happened to the Comsoft V4 thread?

[comsoft]

Removed it by mistake :(

anyway, the fix is gone to production now. it was made mainly for production.
It's not safer then the fix currently sold but will be easyer when on pcb and will have a nice led flashing in blue :)

great.

[Dante_Must_Die]

Can this fix be aplied to v9/v10?
Cuz the romeo is also causing the media to read slower and just bad...

peace

[comsoft]

Yes, the last version (4) can applied easiely to v9.

need a high resolution of v9 board to make installation diagrams.
even though this fix is perfect to v9 also, the romeo mod is esyer to install.

[cakcetin]

Today I apply 20 unit from your fix+summone fix....Good work no problem,thanks again to you....
But I have a question x point and mars pro N point use same point from pstwo mobo this is can damage or can effect work your fix?????
Sorry for crappy english,
Regards...

[comsoft]

No need to worry

Soon ver 4 will be out on pcb, and it not uses this point anymore

[spoiled]

Could you please post hexcode and diagrams for v4? Perhaps update/edit the first post.. Don't think it is already, or?

Would be very kind if you could do this. Thank you

[comsoft]

V4 gone to production. it will be released to the public when it will be out!!!

[evilfox]

Don't know whether this is relevant, but I found this fix on a Dutch retailer website: http://www.hotbit.nl/images/mods/infinity/PS2-V12FIX-II-install.jpg
I haven't got a clue whether it's related to yours but I thought I'd post it.

P.S. I want your fix, combined with Summ0ne's it'd take away my worries while playing ;) Just have to know where to get a single one programmed and ready to solder ;)

the pic imidiate shutdown any current to the lens if thre is a problem , so don't need to use any additional fixes with it. even though the someone fix combines with mine is 100%+ bullet proof :D

I myself installing the pic only (plus the resistors ofcourse) and even without the capaciros , and it works like a charm.

also it saved my personal pstwo lens several times.

i have it on video how the last version (4) saved my lens , but don't know how to upload the AVI file to this forum!

about the link: it's not my fix, it's a combination of matrix pic fix and diode fix.

[evilfox]

Let's wait for somebody to offer to host your AVI file, how big is the file?

[comsoft]

small.

[mabcom]

i can host the file for you on my site www.mabcom.net

Thank u guys :)

[flashharry]

comsoft i have tried your fix & works perfect.. :) i also tried this with a 12c509a it too appeared to work ok but i would like to check with you if theres likely to be any problem even though the test (of lifting the lid before boot) works ok

thanks & good work (version V111 (2))

[flashharry]

forgot to mention i'm gonna use 508's in the future but would you suggest removing the 509's already done

thanks

[comsoft]

both works perfectly. the 12c509 have 1024 bytes insted of 512 bytes that's all.

the Clock Sync value is in the end of the memory location so it's impotent to burn it as 12c509 and not as 12c508 while using the program.

Hi,
I installed summone&matrix pic fix and lastly comsoft&summone fix approximate 200-210 unit.I have only one dead laser before 20 day; really one return not problem for 200 piece (200/1 )
Yesterday I install original MI;slimline v3 comsoft&summone fix(only 560 ohm)Today pstwo turned back because can read cd-cd-r but cannot boot dvd movie ,dvd-r dvd gold,silver:( I measure focus 4.9ohm tracking 5.0ohm and this pstwo have a big laser(not pvr802) so not coil burn but what is the problem?(photo diode problem or not?)
I cannot try this big laser on unmodded mobo because I wonder customer how media used and I want from customer all media when I look him discs I surprised because all disc deep scratched and dirty...I say him please don't use those damn disc...
I give to him new pstwo
so bye bye new pstwo :(

[Robot]

is any protection needed on focus side with comsoft fix installed ? i see on the webpage you say that you decides to remove the caps completely from the focus points as it affected readability of the laser.

Will the focus coild be ok ??

[nexus6]

the Clock Sync value is in the end of the memory location so it's impotent to burn it as 12c509 and not as 12c508 while using the program.

ooops ... I've burned some 12c509 with a 512 setting (didn't matter for psx chips). Will some weird stuff happen ?

[comsoft]

it's probebly don't matter cose when i think of it now , if the program is programming the memory half way , it don't touch the vector at the end of the memory. :)

anyway if the program u use (with the pic) don't jump to the vectoer then thre is no use of it!

the diode dead is purely a customer fault!!!

about the dead diode simptom i had only two and both were with the sony (BIG) lens...

when testing the last SONY len with the dead diode, i found out the pot missures sow 1.9K (WOW) on the DVD (i think) and 300 ohm only on cd (i think).

that don't seem resnable :crazy:

[comsoft]

Neo team release the Neo Fix Plus 3 which is a combination of comsoft fix + diode fix. :D

[cakcetin]

Today second dead pstwo come to me:( (with summone&comsoft fix)
This pstwo have big laser too.Focus 4.9ohm tracking 5.0 ohm this pstwo can read cd,cd-r but cannot boot dvd,dvd-r.
When I put dvd all time disc spin then stop and this already continous.
And with only summone fix even not return dead pstwo so I confused I return to only use summone fix.
I don't know this is laser fault or mobo fault so I need check pstwo mobo with new laser but I haven't big laser:(
Regards.

[T07N]

comsoft, does the diode fix really help?

[flashharry]

well i use comsoft only & no probs as yet, this way the is no restriction on the laser, so no read errors, i want to use summone fix and have read its 100% but its the variables that concern me ie- if you have disc read errors use 1.8k not 2k or even 1.6 on tracking, by default tracking resistor for summone fix is 2k or is this just poor installs that open the variables

[cakcetin]

I hate from this news but today turned back 2 piece pstwo too...
When customer need put scrathed disc on pstwo with only comsoft fix or comsoft summone fix laser don't fry but laser cannot read dvd and when this happen if you need put dvd to pstwo;comsoft fix all time turned off the system but cannot rescue big laser....
Whatever finally I have 4 unit dead big laser and I don't know how many installed comsoft fix with big laser:(
Comsoft do you have a suggestion for this?
I wait and I hope dampro release lenschanger for pstwo...
I hope 4 unit enough for me because I can't find big laser
:(

It's the forth time i see and hear of dead DVD diode on pstwos SONY type lens. and the problem only accure on those lens!!!

when misuring those lens i found that the DVD POT is set on 1.9K which is seems to be too high!!!

[comsoft]

the fix is not ment to protecting the DIODS, it ment of protecting the COILS agains MECHANIC CONTROLLER crash!!!

and again, i also found out this problem accure only on SONY TYPE lens!!!

please messure the resistence of the DVD POT and tell me what u get??

[flashharry]

is this the sony laser you talk about?

thanks

[cakcetin]

Ok Comsoft please don't understand me wrong this is not attack to you or your fix really in a few day I lose 5 wide and big laser so now I changed its by pvr802(big thanks to DAMPRO) and again I used your fix and summone fix with new pvr802 now I wait and I hope not return me again....
Here is the measure for five lens:
1. lens---->one pot 225 ohm other pot(I think this is dvd pot):1190 ohm
2. lens---->one pot 207 ohm other pot 1107 ohm
3. lens---->one pot 206 ohm other pot 1009 ohm
4. lens---->one pot 213 ohm other pot 1307 ohm
5. lens---->one pot 223 ohm other pot 1870 ohm(this last pstwo my last tested and this dead in my hand)
I test it one of them by opened pstwo when happened mechacon crash your fix shutdown pstwo but when I turn on again pstwo cannot read dvd...we cannot save big and wide lens:(
Yes flashharry I talked about that laser.

I use someone fix ( traking resistor) on big laser and comsoft fix on pvr ( Peice of shit)laser

Only time will tell ......

So many dead???

Man i'm installing my fix since day one and till now no returns :rolleyes:

I only had seen it happend on two pstwos with sony lasers. one time while testing with a TDK disk which had lots of scratches and no mechanics contoll happend.

and on the other time it happend to a client and he was burning hes DVDs at 4x speeds.

i can't see how i can improve the fix, since it shutdown all current right after 50 ms of INT crash.
