ODE installation guide for LATE PU-8 Playstation 1 motherboards The LATE PU-8 mainboards can be found in: - most SCPH-100x - most SCPH-3000 & 3500 Why the mainboard called “LATE”, and is there an “EARLY”? Literally, yes! The PU-8 came in two major flavors (EARLY and LATE). You can check which mainboard you have by looking for these marks: 1.

2. The GPU and especially the VRAM area on the top side of the mainboard is different, see picture below 3. The Mechacon controller chip has different sizes, see picture below Development: Guide by: rama seewood...

When you are sure that you have a LATE PU-8 you can follow this guide. 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.

3. IC309 (CXD2510Q) needs to have the following pins lifted: 44, 63, 66 and 69. 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.

5. Please make sure that you have lifted the pins completely. They should not have contact with the motherboard, nor with each other. 6. Now we'll get to the purple area on the mainboard top side. In this area you can see the 67mhz oscillator.

10. The difficult part is now finished, but the lower part of the console shell still needs to be prepared. Clip off the small plastic pin marked below in red. This is necessary to prevent the flex cable from pinching and taking damage during installation.

12. To ensure that the cable sits correctly route it through the slot on the top shield. 13. Prepare the PCB and push all 3 spacers into the xStation board. If you look at it from above they can be found in:...

14. Now grab the other side from the flex cable and carefully connect it to the cable holder on the xStation. When it is done you have to fold the flexcable a bit. Folding it like this is best: 16. Mount the xStation on the posts of the original Disc Drive.

18. Create a folder on your microSD card named “00xstation“ (without quotation marks), then download the latest update files and copy the files update.bin and loader.bin to the 00xstation folder. (https://github.com/x-station/xstation-releases) From now on, your Playstation will boot right into the xStation loader! Development: Guide by: rama...
