comsoft fix V4 (with blue led) is out

Comsoft SLIM Fix V4


the fix is a result of co-operation between Comsoft and Team Xtender to bring u the up to date protection to u'r v12 console :D

This fix is based on the previuse version and coded by XcalibEr aka Comsoft on 25/03/2005 (My birthday :) )

All prodcution made by Xtender team which i found to be a very nice persons to work with.

team Xtender also released a nice video showing the fix working and the LED blinking :D.

the video attached to this Thread!

canges from version 3.2
The TEST mode that was on previus versions has removed, so now it's a resistor and wire short!
insted a led has been added to indicate if pic is active and working properly!!!

to test if the pic is able to shutdown the pstwo, just connect all the wires without the INT line (pin 4) and then turn on pstwo. now the LED sould turn on and off twice (indicating the pic goes into action) and after 2 more seconds the console will shutdown!


explenation on how the PIC Fix works (V4):

1. on boot the pic waits 1 second to let the pstwo fully initioate. in that period of time the LED is turning ON and OFF twice to indicated that the PIC is active.

2. check to see if INT is active (HIGH).
* If fails IMMDIATLY SHUTDOWN RS2400FS and by doing so eliminating all current flow to the CDVD drive and the lens!!!
* If Not fails immidiatly goes to WHATCHDOG routine!!!

3. checks the INT line every 250ms. if at anytime the INT is HIGH the PIC jump to WATCHDOG routine.

5. if 2 more second has passed and the INT line is still not active the PIC 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.

IF EVERYTHING IS WORKING FINE DURING THE WHATCHDOG ROUTINE THE LED TURN ON AND OFF IN APPROX 1 SEC DELAY. IF THERE IS NO SIGNAL ON THE INT LINE , THE LED STOP BLINKING!!!!

also added a movie filmed by me showing the fix in action (saving my pstwo :p ) sorry for the qulity of this movie which filemed on low qulity cammera. (Faild to upload this movie :( hope the admin can help in that)

[bobcat]

nice one ,here in the uk we seem to be in the dark ages when it comes to new fixes we still think the diode fix is the only one around.

[kazimdikici]

Thank you so much, we have been curiously looking forward the v4. Congrulate you.I thank u to share ur hardwork with us before even ur website.I have some questions.
It protects ps2 better than v3.2 I think v3 is used thousand times and what's statistics when it's used alone? There is no value for the capasitor what's the value for v4? And if try to do it by ourselves should we use teh led and resistor ?
If we don't use the led and resistor is there another test mode? How can we use it for v9 and v10, is it better then romeo mode for v9 and v10? Thank you for sharing ur works with us. Congratulations and wish u all the best works..

[comsoft]

Thank u very much :)

i only installed my fix alone without any additional fix, thre is no need for any extras.
I saw it in action couple of time on the same console and it's working fine. coils tested and no change at all. the fix working perfectly. actully its working so good that i stated giving warrenty on the lens as well.

on V4 i had in mind the reduce the number of wires, and also add extra protection of BOOT (from standby) so it now MUTE the RS2400FS directly after the 1 sec dealy if no INT in line!!!

until now i have not even one return with DEAD LENS COILS.

yes u can use it more easiely on V9, if someone can send me a good quality picture of the board i can make installation diagrams. and yes it's better then the romeo , but the romeo is more easy to install and also work very well.

thank u again for u'r support.

Great work Comsoft, will send you mail to order

[nexus6]

thx m8, it did the job

[SDU101]

How about some updated install diagrams?

About the LED. Although it is personal preference, I prefer it that stays constantly on as long as the PIC detects that the INT line is high, and goes turns off then INT is low. If the INT line goes high again it turns back on, or it turns off the pstwo. That way it lets me more easily that the INT line is fine if the LED is constantly on, rather than waiting for the next "blink". But then again, the way the INT line works, I guess the LED will just flicker on and off like mad even if it is fine.

[comsoft]

It can't be done cose the int line has high frequency and the led will not work properly.
the LED is not blinking on it's on. it's related to the INT line directly. in every loop of the WHATCHDOG there is a counter and when a certain amount of GOOD INT apear the LED switched!!!

so it directly indicate that there is DATA FLOW on the INT line.

[SDU101]

I know the INT line is a high frequency line, thats why I said the LED will flicker (blink) like mad. Well another way is to have the LED display the status of the muting of the RS2400FS. If it is not muted the LED stays on. If it is muted the LED turns off.

Well these are just my suggestions. It is your fix afterall and not mine. But like i said I personally prefer it to stay on rather than have it flashing.

You know when you have a flashing pstwo next to your TV, your eyes tend to wonder on the flashing LED rather than the TV. And because you're watch the blinking LED you're not watching yourself driving that Mitsubishi EVO 8, it runs off the race track and losing your pole position in GT4. And that sucks, hehe :D

[tbnlist]

nice work :D !

yea thats what i was thinking too. however, in my own opinion, i think it should blink if theres some kind of error and off when the pstwo is fine. but thats just my opinion ;). nevertheless, great work.

[starosta]

There is some small bug's in Comsoft schematics. Here is corrected schematics of "comsoft fix V4".
Schematics uploaded again. Change between L1 <> L2.

[summ0ne]

why did you leave the L2 and resistor? - you dont need it cause the mute of the rs is tied directly to the RESET line!

just cut the track and solder L1 ;)

[summ0ne]

but would need code change or a weak pullup...

[comsoft]

why did you leave the L2 and resistor? - you dont need it cause the mute of the rs is tied directly to the RESET line!

just cut the track and solder L1 ;)

No it's tied to the mechanics contoller!!!

there is also the possebility to connect L1 without installing L2 and cutting the truck, just L1.

but albert says it's bad to pull down the the RS2400FS wile the MECHANICS CONTOLLER pulling it up.

i don't see what's the problem, that what modchip do eveywere!!!

if it's not hazard to the ps2 then we can leave-out the L2 and the 10k resistor and connect the L1 directly which will make the fix easyer to install!!!

[summ0ne]

yes!
in my subzero circuit i have to cut the track cause the /INT line doesnt have enough juice :D to pull the /MUTE

with the pic you have other possibilities

[comsoft]

But if u do a pull-up the /MUTE , u make the RS2400FS allways active, until the CHIP will FORCE LOW it in case of emergency! that's explain why u don't bother to reconnect the MECHANICS CONTOLLER using the 10k resisotr!!

I don't wan't to LEAVE-OUT the MECHANICS CONTOLLER out of the picture regarding of muting the RS2400FS. i think it's better to leave it as it designed in the first place.

but do u think it so HAZARD to connect the L1 directly witout all the hassle of cutting the track and the 10k resisotor.

need u'r opinion on that!

[summ0ne]

1. well the B G I points are forced directly and they dont kill the mechacon during modchip use.

2. Need to check if your PIC is strong enough to do that (i think it needs 24mA)

3. in a v7 for example the BA5815FM /mute is tied directly to the RESET line, same as reset pins for all ICs on the mobo.

[comsoft]

There is some small bug's in Comsoft schematics. Here is corrected schematics of "comsoft fix V4".

the schematic was not made to be released :D it leaked by mistake :D
It was just a quick draw made for the factory.

there is no real need for resistor for the led becose the PIC12C508 suport up to 30ms of current wich is ok for the led to work properly.

on the prototyps i did't put any resistor just soldered the leg between the GND and the pin 7.

anyway, thanks for u'r REALLY NICE schematics :) good work.

With combined powers we will make a SUPER FIX :D

[comsoft]

1. well the B G I points are forced directly and they dont kill the mechacon during modchip use.

2. Need to check if your PIC is strong enough to do that (i think it needs 24mA)

3. in a v7 for example the BA5815FM /mute is tied directly to the RESET line, same as reset pins for all ICs on the mobo.

1. u absolutly right and that was my point from the first place. that modchips do that all the times and i don't see why there is a need for extra resisotor. ofcourse with the extra comperative resisor it's safer, buy imagane what will happen if well have to do that in every wire of the modchip :)

2. the pic has sinc current of 30ma which is strong enough to drow the MECHANICS CONTROLLER .

3. Don't quite remember, i'll check it out when i'll have time (holiday is comming - passover :) )

just to know, how did u decide that the 24ma sink needed for the job? where did u get this info from?

at start i was installing direcly to L1 point without the cut and all, and after albert told me its dangerous i redid all the console.

but i dont think it's that critical, but again maby i'm wrong :D

[solidusuk]

can u help me here Comsoft, I ordered a fix from http://www.gameworlddirect.co.uk/ (it was the summone fix) but the great guys at gameworld upgraded my fix to the Comsoft Slimline Fix v3



which was very nice of those guys, but i have 3 questions.


1. Where can I find a diagram showing me the solder points for that fix.

2. Apart from the blinking LED and maybe less wire count???? is it worth me upgrading from v3 to v4?

2. Later on will it be easy for me to simply replace the V3 fix with the v4 fix and if so how?????

[mjh74]

I too have received the same v3 board from the same place today rather than the pic and resistors for the matrix and summ0ne fix.... I have seen the install pics around but was wondering if I should wait for v4. This PSTWO is going to someone who could be troublesome so I want to be sure. :D

did u get the PCB version ??? or a pic??

1. diagram attached to this message.
2. a bit change in the code for the boot sequence - abit improvment.
don't have to upgrade, the V4 works great - not even one return yet!

3. U need to replace the old one, ofcourse :)

I faild to upload the diagrams :(

[mjh74]

It'll be the same as mine. An SMD PIC with "comsoft" printed on it on a white PCB saying slimfix v3 :D

[comsoft]

Faild to upload the diagrams so i attached a link :
http://www.divineo.cn/divineo_support/products/ps2-sfv3/files/slimlinefix_v3.jpg

[solidusuk]

ok thanks com, yes its exactly the same picture you see in the diveno site.

but my 3rd question is simply, I will install the V3 fix and say in about a months time I decide to buy the V4 fix the wires will not install to the same place will they???

so is thier a v4 diagram?

[comsoft]

The wires are the same, but the positioning of the PCB on the pstwo board can be different from the one u installed and though the wire length as well.

[Morpherex]

This fix doesn't shut the console down DURING play.... Does it?

[comsoft]

This fix doesn't shut the console down DURING play.... Does it?

until now i never had seen it shtting down the console during play. all crashed happend during boot when the disk start loading.

anyway if it will happend u should be thankfull since it saved u'r lens :D

[T07N]

That would suck if you were doing the 24 hours race in GT4 and it shuts down.

[SDU101]

Well I'd rather waste a few hours work on GT4 than lose probably days and money bacause you have to wait for your new lens to arrive.

[bunghoolio]

Can I leave PIN 7 disconnected because I don't want to use LED???

[comsoft]

Yea. u don't have to connect it!!!

[comsoft]

That would suck if you were doing the 24 hours race in GT4 and it shuts down.

Yea but u forgetting something importent here!!!

the fix shutting down the console only when the system has been crashed, though u can't continue to play the game anyway!!!!

but insted to figure it out u'r self (which takes time) and getting from the couch to pull the powercord out , and by that loosing the lens on the way, the fix does that for u!!

1. saves the lens
2. shutting down to console and saving u the need to pull out the power cord.

[rsivan]

I have some console with comsoft fix v4, when hot and I unplug the power and replug it the red led don't turn on and I need to wait....
with 1,8k resistor on J pin the problem not appear...

Can I use 1,8k as standard for all my console?

however I will test ever if shutdown feature work by putting the k pin to GND with result of an istant shutdown

[comsoft]

where go getting the 5v from??
which board this problem appear??

and yes, if the chip can shutdown with 1.8k, then u can use it!
I had to replace the resistor only twice , but that when i used alternate 5v from the USB.

i idea to solve this problem for good on next version.

good day

Yupe I'm having this same problem! With the PSU connected to the modo and the 5V line removed as well I can get the reset light to come on. Then while the PSU is still lugged in if I solder the %v line I can then get the chip to activate.

With the 5v line connected and the PSU unplugged the red redet light wont come on when the PSU is plugged in. I'm useing the points in your diagram comsoft. Unlike rsivan if I wait the rest light never comes on. I will up the ohms on J line and see what results I get.

Looks like there might be bugs with the V4 version :(

[spedmetal]

**UPDATE**

Bringing the ohms on J line up to 2100 fixed this problem. I lifted INT. line and at 2100 ohms it was still able to turn the console off :D. Get work Comsoft. Comsoft maybe on the next version you should have 3 resistors (1500, 1800, 2100) so people will have an option if the lowest one doesnt work.

[flashharry]

comsoft i have used ver 3.2 hex on console that have gone out are these likely to be ok?

thanks

[comsoft]

the V3.2 is accelent. just have more wires to install :)

there are no bugs, those problems are hardware related.
Until now i something femiler only once.

and the pstwo red led was on only when turing on the PS2 while the eject button was pressed.

tray replacing the 1.5k resistor to 1.8k or 2.1k or 2.7k.

[spedmetal]

Thus the reason for my post. A bug is a bug is a bug no matter if it be hardware or software.

tray replacing the 1.5k resistor to 1.8k or 2.1k or 2.7k.

Thanks.... already did that as I posted about. Works very well now. Now all I have to do is get a bunch of surfaced mounted resisters 1800 and 2100 so I can remedy this bug on any other console I might install them on :rolleyes:

[bunghoolio]

I have noticed that any PAL console marked 70002b will need 1.8k or higher resistor
Any PAL console marked 70002a can take 1.5k or 1.8k or 2.2k resistor. for J point
Hope that helps PAL Modders

Supporting comsoft, it is a hardware related issue, according to the matrix team. Original source here (http://www.infinitymod.com/cgi-bin/matrix/site.pl?page=laserv12)

Important notes:
The resistor value (1500 Ohm) has been chosen as the best value according to our tests.
If the value is less than 1000ohm the pstwo will stay in a permanent reset state and not even the red led
will turn on.
On the other end if the value is higher than 3300 ohms the pic will not be able to turn off the pstwo when
needed. This has been tested on several machines with consistent behaviour.
However there might be other board revisions which might behave in a different way (maybe because of a
different reset controller IC used).

So if you experience problems with the 1500 Ohm resistor, you can probably safely increase it to 2000/2200
ohms. Please, only experiment with different values if you understand what has been said (or if you don't
care about running your pstwo without being sure that the coils protection is working).

So, like comsoft said, if 1.5k doesn't work, try replacing it with 1.8k or higher.
My 2 cents...

[spedmetal]

Supporting comsoft, it is a hardware related issue, according to the matrix team.

Yupe your right its a hardware related "BUG" that we all knew about from the Matrix PIC fix days... that's how we got the idea to raise the value on the resisters. :p

Looking forward to what Comsoft comes up with the get around it with out adding 3 combinations of resister values on the next version.

Comsoft I want to thank you for a great fix. The V4 version is working very well and I love the LED. Not only does it look cool but it lets you know everything is working like it should. Good job man!

V4 is in stock, any orders will be wellcome :)
email to comsoft@cso.co.il for orders

prices are between 6$ for low quantities (25-50 pcs) and 3$ for 1000 pcs.

thanks and good day

[viper357]

Comsoft, you seem to be doing excellent work, keep it up. Do you have another website that is in english?

[comsoft]

I working on a very simple website only for the fix.
will be finished soon.

Here is a little video clip of the comsoft v4 in action.

It is a divx codex so if you dont have it you might need it to view.

[cakcetin]

Comsoft for next version can you make a preventive mode for pstwo laser diode?
If pstwo when need read scratched or crappy media can shutdown system or can cut power of pstwo laser?
Sorry for bad English.

I think of addjusting the DVD pot the higher resistence will reduce the damage, but will be picky on disks :)

Picking disc not problem mean I need pstwo cannot try read scratched disc or crappy media.

Most likely a problem with either the button, ribbon cbale, or LED. I cant see how it would effect "just" the green from not coming on on the one LED.

[bunghoolio]

Thank you Comsoft for XLENT Work. I started using this fix 2 months ago. Still no come backs...touch wood??? Has anyone had probs yet with this fix. (I am assuming you all R installing it correctly?) By the way... matrix fixes really suk. Most come back in less than 3 months!!!

[Gwil]

Quick question, this looks like a good fix to go for, I'm in the UK, and the site I was gonna buy the modchip from only does the 3.2 version of the fix. Is the status LED the only difference between it and the v4, or are there other functional differences? If it is worth getting a V4 over a 3.2 is there anywhere in the UK I can buy a v4 one from?
Thanks.

[bunghoolio]

Hi Comsoft. How do I buy 250 PCB's for V4 fix. I only want the circuit board, no PIC, no resistors, no capicitor etc, JUST the PCB??

the differences are the LED and Less wires to install.
also faster response on boot but i have no one return since the end of last year in wich i started to use this fix.

so u can buy it and sleep well.

I can't understand u, at prices low as 5$ each , why would u like to buy it without the components.

i already offered u 250 pcs for only 4.5$ + shipping , ready to install.

if u pay my tommorow u'll get it in 2-3 days by DHL.

thanks

You might not have to replace it. You would only need to replace the 1.5K resistor if you were having trouble with it after the install. Install it like normal, if after that you have trouble then consider replacing it. Like Comsoft himself said, I too have only had a few consoles that I actually needed to replace the resistor with a larger one.

[comsoft]

more then 90% of the cases there is no need to replace the resistor!!!

and on the times i did had to replace it is when i used alt point for the 5v.

until now i had only one case (if i remember correctly) that i had to replace the 1.5k resistor with higher resistence when u used the 5V as in the diagram!

[MrR]

I have a very stange problem with some of my lastest pstwo installs which I have never experienced before and it is freaking me out.
I use infinity + comsoft v4 fix and I have had several times the pstwo locks in a constant reset state. (directly from standby when the unit is turned on) When I remove the chip + fix and extremely clean the board the problem still remains. I have about 6 units collected now with this problem.
I most certainly don't want to blame the fix but I didn't have this problem before I started using v4 fix. I'm convinced this is a superb fix and have had no return since. i do about 4 installs a day atm.
Hope someone else has this problem and maybe somebody have a solution because i'm lost.

thanx

[comsoft]

If u removed the chip + fix and te problem remains, then it's an installation issue.

[MFR]

I installed a matrix infinity with the slimfix v4. it worked well for two weeks. now it wont read disks. i replaced the laser and it works fine again. do i have to worry about it failing again? the MB is GH-035-22.

[comsoft]

which disks it couldn't read??? DVDs?
which type of len was on that pstwo? wide one?

check the connectivity to the INT line!!! if it's not connected well then the fix wount work!!!!

Even with the best fix's the slim ps2s' lasers are experiencing problems... not with the coils but with the diode.

Sorry I didnt try all media types but it wouldnt play backup ps2 or dvd movies. not sure what laser. i can tell you it moved on one bar and on the other side it was on the frame.

this is the laser i have is it the wide or slim?

[davbere]

slim

Its safe to use this fix with a wide laser (SPU3170J) ??

Tnx

[automan]

someone tried the comsoft fix on the new v13 board ?

[comsoft]

Its safe to use this fix with a wide laser (SPU3170J) ??

Tnx

combine it with diode fix and u have perfect solution for wide lesers

the thread is sticky again, thanks to loy.
feel free to ask your questions.

[funkydk]

Do anybody have a diagram for Slimfix 4 on the new PSTwo v13? It's not 100% the same

[comsoft]

as soon as i'll have v13 i'll release a diagram.

[funkydk]

I hope really soon, have already many v13 consoles waiting.

Do you have an idea on when we can expect it?

[nexus6]

I thought V13 don't fry their lasers and therefore don't need any fixes ?

[comsoft]

I didn't even got one yet :(

but i also read that there is an implimentation of my fix on board.

[MaximusDK]

Does any1 have a burned laser with this Slimfix V4? or can we call it safe when the fix is installed?
does it function with all types of modchips? do i need to make an fix also to protect the coils?

regards MaximusDK

We have used Slimfix V4 on a lot of V12's, without any returns.

[MaximusDK]

okay dos this fix also makes the PS twos with WIDE lasers safe to mod? do you install any other fix on the machine also? maybe summones.... i understand it like it just protects the laser diode, but not the coils? or am i wrong?

Regards MaximusDK

[summ0ne]

the comsoft fix is not enough - you need the summ0ne on tracking.

otherwise you will have consoles die on you after a few weeks of use

[MaximusDK]

okay thx m8! do u know if this slimfix helps the Wide laser versions also? hear that there are alot of problems with the wide lasers!?!?

Regards MaximusDK

[summ0ne]

not if you do the fix ;-)

[viper357]

can i just get some clarity here guys, do all slimline machines need both the comsoft and the summone fix ?

[MaximusDK]

same question as mine, and i think you need to install both.

[viper357]

yeah, i don't really want to work on any slimlines until there is a solid solution, but if we install both the comsoft and summone fix, does it solve all the problems on all the slimlines? I don't want people coming back to me with problems

[funkydk]

I'm still waiting for a diagram for PSTwo v13!

v13 need no fix.

i install 3 v12/v13 per day and lately im on s streak with no burnouts at all (last 3 months)

[MaximusDK]

okay cool m8 thx! know we can get back to buisness :) havent made a PS2 in quite some time now so im looking forward to testeing these new fix :) both fix just came in the dore yesterday so now theres som testing to do :)
and again thx for all your efforts to solve this problem :)

[viper357]

yeah, thats fantastic news, i am going to combine the comsoft and summone fix onto 2 of my own personal slimline ps2's and test them thoroughly.

MaximusDK....let us know your results.

p.s. off topic just a bit....where is the best place to buy these 2 fixes with credit card?

[comsoft]

in all the WIDE LENS i combined the comsoft fix with the diode fix and got no return yet.

or u can just addjust the DVD pot to hiegher resestence to reduce the laser intensity.

[comsoft]

the comsoft fix is not enough - you need the summ0ne on tracking.

otherwise you will have consoles die on you after a few weeks of use

how did u get to this conclution??

i have lots of consoles arived to me that has coils burned out and has your fix on it!!!

i'm using my fix (and also u do on you'r subzero fix and you'r new modchip) for all my premodified consoles and none has returned since december last year...

[comsoft]

can i just get some clarity here guys, do all slimline machines need both the comsoft and the summone fix ?

NO the comsoft fix working 100% safe for the coils.
if you have the wide lens, just combine the diode fix with the comsoft fix and u got a solution. if u like u can use the summone fix insted of the diodes.

other way is to increase the DVD POT resistence on the SPU3170 (wide lens) until it will stop to read scratched disks but will read good disks.

u must mod no consoles at all...
cause your fix dont do shit. the tracking coil burnout has nothing to do with mecha crashes.

i actually believed your statement when u were using your fix "for 3 months" and no returns... thats a LIE!!

u need my first fix on the tracking coil...

[summ0ne]

every single console with just the shutdown part of the subzero fix came back with burnt tracking coils. - after applying the tracking fix, no consoles returned and the operation of the dvd drive is more silent, ALL media work (good and bad) so everyone is happy.
that is how i came to this theory: http://www.ps2-scene.org/forums/showthread.php?t=37865 (it works very well)

If you are saying that for 8 months youve been using the comsoft fix with no other fix you are lying to these people right here just to sell a fix or two.

And telling them to apply the diodes fix - just not to use mine, it takes 8 times more work.

Thats pathetic. Be bigger than that! Help them have a safely modded console with ANY good combination of fixes.

Heres a newsflash: The v13 is out and it needs no fix - so you will not sell any more fixes!

[MaximusDK]

dont worry SummOne! we install both fix! just glad that there is a solution to this problem now, and its working. thx again for all the work!

you are full of shit. first u use it (our idea of shutting down the RS2004FS) in you fix since your shitty one resistor solution turn out its not working anymore. and now you change all facts to feet your needs.

IF IT'S NOT ALL, you'r taking others solutions and ideas and making it your's.

albert was right all alone, i was the stuped to think u worth something.

go and clone another chip, and convince ppl that your doing it just for contributing the scene.

first u used the BM to sell you shitty subzero chip, now u cloned the MATRIX INFINITY SHAPE.

the fact that u added the RS2004FS mute to your "ultimate one resistor fix" just saying it all :)

EAT YOUR HEART, since my fix PROVED TO BE WORKING 100%, and i'm using it and many others as well and got not even one COILS burn out since DECEMBER 2004.

and if MY FIX is not working , than how come your SHITTY implementation of OUR IDEA is suppose to be better when it only SHUT the RS2004FS and don't have all the features that the code in the fix does.

EAT YOU HEART summmmmmone

[Robot]

******you are full of shit. first u use it (our idea of shutting down the RS2004FS) in you fix since your shitty one resistor solution turn out its not working anymore. and now you change all facts to feet your needs.*****

where you've been in the last year or so?????

all the matrix team fix was is just shutting down the ps2 when mechanics crash has happend and even that it didn't do well.

suddenly all the facts are fading..

please go back couple of months and read, before posting , in case you don't remember.

our fix was to mute the RS2004FS in case of crash, thats the whole idea of the comsoft fix.

the fact with combined it with the matrix team idea of using the INTERRUPT line to determine that the DSP/MECH are crashed was after we so that other solution will have to be with more components.

there is no one line of my code belong to the matrix team, there code was messy.

suddenly, all the credints of my work going to the mighty SUMMONE.

u know what,

THis forum full of ass liking stuped lieng hipocrits.
and i don't give a damb if i'll be ban for that.

[summ0ne]

comsoft, there is NO WAY that your shutdown fix or my shutdown fix will keep the tracking coil from burning on 683 and 303 consoles.

I do not know htf you do not know that, but its true.

WHY T F do u think sony changed all the resistors to 01d?????

v13 have the equivalent of the subzero fix PCB = coil output shutdown + limited tracking signal.

read the first post in this thread already:
http://www.ps2-scene.org/forums/showthread.php?t=37865
and for the sake of people that look for a safe fix in here stop saying your nonsense or THEY WILL DAMAGE THEIR PS2 listening to you.

[summ0ne]

p.s.
the subzero fix pcb is 100% safe when applied according to my diagram. so is the h2o mod.
the summ0ne fix is 95% safe and is still safer than yours!

the fact that u added the RS2004FS mute to your "ultimate one resistor fix" just saying it all :)
nope, i added the tracking resistor to YOUR NON WORKING UNSAFE shutdown fix

[Robot]

damn guys , this my protection is better than yours is getting out of hand , especially the language you guys are starting to use . Why dont u guys just agree to dissagree . Fact is , i had blown laser with summone fix(resistors) , blown laser with Comsoft fix V4, reading problems with someone fix (Resistors) after about 15 mins of use . These where all with 5v chips. Ive been using 3.3v chips for 3 months now with Neofix with no melted lasers , only dead SPU now which none of your fixes can prevent

[davbere]

whats spu ?

wide lens

[davbere]

thanks

[Robot]

thank god that the full replacement pvr thin laser is not that costly. :)

[davbere]

amen
I have not had to replace a single laser using just the comsoft or subzero fix.
I share Tonys opinioin...I dont trim the laser diode either. then again there are not many of the wide laser ps2's sold here ...or I have been lucky not to get them.
SomeOne...Comsoft great fixes.

Peace

[summ0ne]

Robot, it is all good.
I had the same situation as you

At first no returns with my summ0ne fix.
Then started using the subzero fix to be able to provide better support for it.
-Discovered that on 683 and 303 consoles burnt tracking coils.
-Discovered that it reads better without the focus resistor.
-Explained in theory why the tracking coils are not safe with any shutdown fix.
-Backed it up by extensive testing.
-$ony came to the same conclusions - evident from their v13 design.
Then 4 out of 100 consoles came back with the old summ0ne fix.
CONCLUSION: shutdown fix + tracking resistor = 100% safe + no reading probs

Thats basically it.

But dont draw any conclusions about 5v/3v chips.
It does not matter what voltage it is, as the modchip is connected IN PARALLELL to the signal and NOT IN SERIES (cutting a crack and inserting 2 connections).
So the modchip patches BY CURRENT and NOT BY VOLTAGE.

and all the mcus/fpgas used for modchips have roughly the same range current.

The only dangerous stuff that can happen is that the chip can not provide a high enough current for patching (defective Actel chips on Matrix Infinity) and then you have nonworking chips that you fix by RAISING the voltage. And the other chips sometimes patch, sometimes dont - and that way cause lots of crashes.

All i use are 5v chips. (Not that 3v chips are any different.)

[comsoft]

p.s.
the subzero fix pcb is 100% safe when applied according to my diagram. so is the h2o mod.
the summ0ne fix is 95% safe and is still safer than yours!

nope, i added the tracking resistor to YOUR NON WORKING UNSAFE shutdown fix

U don't have a bit of shame do u ???

how is my fix lesser then yours when you used our idea in it and you only implemented one feature of it, the RS2004FS shutting down after 50ms.

here is a link to a thread YOU published and in wich YOU saying you are imlementing the COMSOFT idea in you'r fix.

http://www.ps2-scene.org/forums/showthread.php?t=33887&highlight=subzero

as you say in this thread:

So for the last day ive been killing my mind how to combine the comsoft pic fix and mine on pcb and still make it fast + cheap enough for people to buy...

Then when i saw that you can mute the RS2004FS driver without using a PIC!!!.

so at first u take our idea and give credit for it, but when time goes by yo take all the credit's to your self to promote your AMAIZING fix!!!!

sony imlemented the COMSOFT FIX on board (you can see that thay also used a pic for it) not you 2 cent fix. but instead of using the INT as an input thay used the tracking and focues lines to determine if shutting of all current neaded.

but when u SAY thay used "your" fix? what do you mean?
i don't see any resistor bridging the FOCUS and TRACKING resistors!!!

what i see is a system which SUTTING DOWN RS2400FS in which u also used it on your fix (that's right) but it was the idea of me and albert from the first place.

if u want me to bring more backword links to probe my point i'll do that.

but the shame is that this forum have a very short and selective memory.
and i wonder WHY???

[9HOMERSIMPSON9]

Fighting is a sign of love.

[summ0ne]

but when u SAY thay used "your" fix? what do you mean?
i don't see any resistor bridging the FOCUS and TRACKING resistors!!!

If you had ANY engineering knowledge, you would see that they use the same combo as I:

besides shutting down the RS2004, they LIMIT the current ON TRACKING.
- i bridge it cause its less work for me.
- they replace the 303 with 01d cause its less work for them.

The fact that your comsoft v4 fix DOES NOT LIMIT TRACKING signal makes it unsafe.

1.
SubZero fix applies resistor to tracking.
$ony replaces tracking resistors.
Comsoft DOES NOTHING ---------> dead v12

2.
SubZero fix does not turn off ps2, cause it is unnecesarry, it can even resume CD reading operation if there was a false allarm on the /INT line
$ony does not turn off ps2, cause it is unnecesarry, it can even resume CD reading operation if there was a false allarm on the /INT line
Comsoft turns off ps2 - WHY? what for?


so comsoft, lets compare some key functionality differences in fixes:

Wire count:
Comsoft: 6 (shutdown part only), NO TRACKING PROTECTION
SubZero: 3 (shutdown part), 2 tracking protection

Safety:
Comsoft: safe only on 01d consoles
SubZero: safe on ALL consoles

Failsafe mechanism:
Comsoft: if there is anything wrong with the fix and the L1 and L2 points are soldered, the ps2 will burn and damage lens PERMANENTLY on any console
Subzero2: if after test mode anything is wrong with the protection, the ps2 will refuse to boot cds until it is fixed.

[summ0ne]

So the moral of the story...

not only is my fix 10 times cheaper, but
1. I TOOK NO COMPROMIZES IN THE PROCESS
2. I ADDED ALL THE SHIT I COULD THINK OF IN MY IMPLEMENTATION
making it ACTUALLY SAFE and AS EASY TO USE AS POSSIBLE at a NEXT TO NOTHING price.

[comsoft]

Summone, u have nurve.
I'm tierd today, i reply to you bullshit tommorow.

[MiH]

to summOne:
You mean that replace the tracking resistor to 01d (100k) is functionally identicall as your 560R (2k) resistor bridge?

to Comsoft:
What type of PIC is required for your fix, please. 12C508A or 12F629? Is your HEX file released identicall with HEX used on final boards?

PS: Please, you both have my big respect for your knowledge and hard work for PS2 users. You both is very clevers, pls stop this stupid war.

[summ0ne]

to summOne:
You mean that replace the tracking resistor to 01d (100k) is functionally identicall as your 560R (2k) resistor bridge?

Yes, altho the particular values used here vary a bit.

[MiH]

Yes, altho the particular values used here vary a bit.

Thank you for answer. I would like to ask you for particular values of resistors for 683 and 303 versions, if you know it. I preferr exchange some parts as adding. It's seems clearly for me.

[summ0ne]

You get the equivalent of the summ0ne fix by replacing the resistors to:

tracking: 130k
focus: 43k

so, thats: http://d-vices.com/summ0ne-invisible.jpg
303 -> 130k (tracking summ0ne)
683 -> 130k (tracking summ0ne)
01d -> 130k (tracking summ0ne)
303 -> 43k (focus summ0ne)


if you are using a shutdown fix, this is enough:
303 -> 100k (tracking summ0ne)
683 -> 100k (tracking summ0ne)
01d -> 100k=01d already (tracking summ0ne)

[MiH]

Really thank you for your help. I was reading many hour threads about fixes. And finally I decide to use your summ0ne fix in conjuction with comsoft PIC shutdown fix.
Your RC circuit is genius simply and effective.
PIC program is more precise to detect fault state as your RC circuit, I think. Have a LED indication about current state (it's nice for customers, they like it) and higher price of PIC, will pay a customer.
As I wrote before, you-Summ0ne and Comsoft have my big respect.
Thanks both again and keep your great and useful work.

try connect the +5 of the chip to the alt +5.1 v point

it might work , not sure

spedmetal was talking about replacing the J resister ? I tried a 2k ohm and didnt work

nevermind... i just removed that POS fix and used summ0nes fix.

done afew v12 now with com v4 fix 50% have come back work ok with origanals soon as you put backup in it powers off

[bobcat]

hi there if using comsoft v3 and the resistores are 01d can you leave the f1 nad f2 solder points off .

[MaximusDK]

okay now im confused, i have just installede Slimline fix v4 in to v12, and i just connectet the 4 wires that was presoldered on the fix. i souldent solder any other wires right? the protection fix is blinking blue (looks cool) so I was sure that i did it okay.

havent wired a F1 or F2 wire?

BTW: have someone got a V12 with the Slimline fix v4 back with a burned laser?

Regards MaximusDK

[spedmetal]

What are you confused about?

There is no F1 or F2 to solder with the Comsoft V4, that was with the Comsift V3. When installed correctly the Comsoft V4 works just fine and I can say that I have yet to see a laser burn out with it.

Just make sure you cut the track like the diagram shows or the fix wont protect the laser like its suppose to.

[MaximusDK]

okay thx, it was just the F1 and F2 part i was confused about m8! :)
well im almost sure that i cut the track thrugh, but dos the fix still blinks blue if the track is not cut?

Regards MaximusDK

[bobcat]

to test the v4 fix do you leave the k wire of to see if it as been put in right and the blue led blink twice then switch off thanks .
