V3 Modbo modchip installation diagram

One of the revisions of the fat PlayStation 2 was the V3. They were found in many of the earliest SCPH-3000x systems. Matching console model numbers and board numbers are listed below.

I sell Modbo 5.0 modchips in my store.

You can find the model number on the sticker on the bottom of the console, and the board number is printed on the PS2 main board if you take apart your console. Note that there can be multiple board numbers within a specific model number.

  • NTSC-U/C (United States)
    • SCPH-30001 (GH-006)
  • PAL
    • SCPH-30002 (GH-007)
    • SCPH-30003 (GH-007)
    • SCPH-30004 (GH-007)

Note that there are multiple versions of the Modbo modchips available, but the installation diagrams are all the same. Some example versions are Modbo 3.0, Modbo 4.0, Modbo 5.0, and Modbo 750.

The V3 board revision may not be compatible with the newer Modbo 4.0/5.0/750 chips being sold today.

Modbo modchip pinout

Some V3 consoles have a gap in the middle of the pins of the BIOS chip (near pins P, O, N, M, Q, T, U, and V). Use the BIOS GAP part of the diagram for those systems. If there isn't a gap in the pins then use the BIOS NO GAP part of the diagram.

The diagram below says it's for a Japanese system. The same diagram works for American and PAL systems if the H pin is not connected.

Installation tips

Here are some tips I have for you when you are soldering your chip into a V3.

  • Using 30 AWG solid core wire works well for most of the points.
  • Use some thicker wire for the 5V and ground wires.

Example installations

This section has photos of some successful installations which you can use to get a better understanding of how everything is wired and positioned. Leave a comment and I'll add your installation to the list

Hello! Thanks for your guides, very helpful. I have installed a Modbo 5.0 on a SCPH-30003 (GH-007) and it works great. I've attached a photo.

The differences to your guide were;
 

  1. I found it easier to solder to the V and U at alternate points. This isn't required.
  2. The CX point is different (see photo below)

Hey James, I just did Modbo 5.0 install on a v3 SCPH-30004 GH-007 board, but when I power on the console I get the Matrix screen and nothing else. I also cannot enter the Matrix config menu by holding triangle and circle. I didn't connect the H wire as my board is PAL version. All the other letters are connected to the same points as yours. Is there any reason the H wire is connected in your picture, I thought the 30003 was PAL exclusive version? I tested the system prior the mod and even ran FMCB on it and… Read more »

Oh, the impression I got from the guides was that the H wire is meant to be connected only on NTSC (and maybe Australian) consoles, regardless the Modbo version. I guess I was wrong then. I'll see if connecting the H wire will get past the Matrix screen.

For some reason I can't attach a pictures to my replies. It says the file type is not allowed. It's a JPG. Maybe I'll try on PC later. Currently on Android/Chrome.

Hello! I have some doubt... First diagram, it belongs to Mobdo 3.0, and the second belongs to Mobdo 5.0. The chips are very different, because Mobdo 3.0 doesn't have CX point as Mobdo 5.0. Which CX point is equivalent in mobdo 3.0? What is it GAP? How do I know there is GAP? Thanks

Just as i thought i wasn't to sure about it i verified it with a multimeter and it's connected to to the second pin of the chip and i'm not so sure where i should solder it what do you think where would be a good place to solder it

Hello guys,

I accidentally broke the small device at the 3.3V connection point (V3).

Can someone of you tell me which type of part (resistor etc.) it is?

It would be very nice to get the possibility to fix it with a new part.
