xStation ODE installation guide for the PU-18 Playstation 1
motherboard
PU-18 Mainboards can be found in:
All SCPH-5001

All SCPH-5552
(very rarely) SCPH-7001 –7003
1. You have to disassemble the Playstation 1 completely to get to the
mainboard. PLEASE REMOVE ALL CABLES FROM THE POWER SUPPLY. MAKE
SURE THAT THE POWER CORD IS DISCONNECTED!
2. Search for IC701
- IC701 is labeled CXD2545Q. You will find it in the lower right corner. See

3. From IC701 (CXD2545Q) you have to lift the following pins:
45, 46, 47, 56, 74, 77,78 and 80.
Please make sure that only the shown pins are lifted.
4. Please be careful not to damage the mainboard when lifting pins. Use a
needle or x-acto knife and a fine soldering tip to simply touch the pin and apply
some heat, then gently lift it from underneath using the needle or blade. (In the
picture I have turned the mainboard to get easier access to the pins

5. Please make sure that you have lifted the pins completely. They should have
no contact with the motherboard
6. We are now finished with the top of the mainboard; turn it bottom side up.
Now you have to solder the Quick Solder Board (QSB). Focus on the area
marked below.

7. The positioning is kept very simple and can already be seen at the solder
pads of the QSB. Simply place the QSB on the mainboard as shown, the yellow
markings make it clear again.
8. Before soldering, the via pads on the left and on the right (yellow circle
marked in the picture above) need to be lightly scratched.

12. The difficult part is now finished, but the lower part of the PS1 case still
needs to be prepared. Cut off the small plastic pin marked below in red. This is
necessary to prevent the flex cable from breaking during installation.
13. Now you have to connect the flex cable to the cable holder on the QSB.
(blue side up) and close the cable holder. When this is done you can lead the
flex cable outside

at it from above they can be found in:
- the lower right corner
- the upper right corner
- the upper left corner.

bit. Folding it like this is best:
17. Mount the xStation on the posts of the original Disc Drive.
It should look like this:
