Question from a newbie with Octapus chip

**giansi** · 02-21-2006,09:46 AM

Hi all!
I have a v12 pstwo, and I just ordered a Octapus3d chip because it seems quite easy to solder for a newbie like me :-)

Just a question I wondered: ok, we have 9 wires to soldier, to connect the Octapus to the ps2 motherboard...but how can I *FIX* the Octapus to the mb? Does it fit somewhere, or I have to use glue, adhesive tape or whatever?

Thanks,
Luca from Italy

if solderd corectly no glue is needed

Thanks for your answer!
I meant: motherboard and octapus are "tied" by 9 wires, but the modchip is able to move, because it seems (I still don't have the chip in my hand, I think it will arrive tomorrow) that there are no solder points which directly connect octapus and ps2 motherboard...just those 9 wires..
Am I wrong?

chip is conected via 9 points on the bios and 9 wires look at octapus.net for your diagram

Yes, those types of chips are deceiving. There are 9 wires plus 9 connections to the bios pins so its not any less soldering than a chip. The modchip lies on top of your bios chip and then you run/trickle solder down from the chip to the bios point. I hate those types of connections and usually end up running wire instead. Same thing with the XBox 1.6 LPC rebuild boards. More of a pain to try and solder it to the motherboard than to cut and solder 6 wires, IMO anyways.

here you can see how you connect octapus to ps2 mainboard,
and here is a typical installation in a v12 ps2 console.

It is very easy to solder the pads of octapus in the mainboard,
and don't worry cause if you make a mistake
you can remove it easilly and try again as many times you wish,
thanks to the flexible pcb.

You still have to watch out for bridging the bios points, more so on an older version rather than the v12's since the v12's just have the points to solder where as older ones have the chip.

Thanks all for your answers!
I saw the picture regarding "soldering bios" on Octapus site, but I didn't understand what it meant, I never had a modchip in my hands, so I wandered what *bios* was in a ps2 motherboard..

Last question: Yesterday I disassembled my pstwo slim, and I discovered it has a v.14 motherboard (I thought I had a v12!) ..does it need the lensfix like v12? On Octapus site it seems v12 only needs Zener fix.

Should I solder the lens fix as it were a v12 moterboard, or it's useless with newer version?
Thanks,
Luca

I agree 100%

y

If you can solder one point, you can also solder 22 points (eg. MI). If you can't solder 22 points, you can't solder 9 points.

All i'm saying is, that no modchip is harder to install than others. It's just a matter of how long it takes.
