Click to expand.Matrix (the real deal) had optimizations on the CPLD code which allowed it to work with just the A, B and I wires on NTSC-U/C machines. It would require more or less wires depending on the region (as the bits which need patch on the chip bus can change due to different data requiring path) and on later machines it require all wires to be connected. But indeed on early PS2s you can get away with three or 4 wires on the DVD drive bus instead of all 5 (or all 9 in earlier modchip designs). Robust Programming Design there.

Honda Ecu Diagnostic Software. The BIOS wires (MNOPQTUVRW) are aways required. In the particular case of using the modchip as boot device for a laser-less PS2 unit you can connect just the bios wires, the reset pin and power to the chip as you won't need to patch the DVD drive if it has no optical pickup to begin with. And you have me jealous now because that's one of the board types I don't have on my collection lol And I have MOST of them!

Thanks for the info! Yeah, I got pretty lucky, and I got a good deal too, managed to talk the seller down to $30 Have you tried looking on eBay Australia for them?

*EDIT* I notice the store I brought the modchip from included what appears to be a laser protection circuit. This is unnecessary for my V3 PS2 correct?

*EDIT* Managed to get some solder all over the legs of that chip you need to solder a few wires to, creating a LOT of bridges. My solder pump can't remove it, so now I need to go buy some solder braid: Sweet Jesus, it's so fiddly soldering wires to those tiny tiny legs!

Well, either way, I manged to get the wires to stick to where they should be, but I think in the process of trying to get it to work, due to either the roughed up legs (some of them look bent) or the bridges or perhaps improper modchip installation (my board didn't have the 'CX' point the installation diagram referenced), the PS2 will no longer start up.

Up for sale is a new PS2 slim. It is modded with Duo 3 Ultra, a very stable modchip. It can play backups, allows you to use various types of homebrew programs, and. The Duo 3 Ultra Chip has 3 boot modes. Fully Auto detect PS2, PSX and movie mode.

I get the power on light and the fan starts up, the drive will open and close, but nothing on screen and no audio.
