Wondering where to get Mod Chips?  Check out some of the links on the following pages to visit vendors that sell Mod Chips.  I'm working on getting a site up so that I can distribute Mod Chips, so keep your eye on this page in the future.  But in the meanwhile, if you don't want to buy a Mod Chip, maybe you want to take the more experienced root, and burn your own chips.  Burning chips is simple.  The links on the next page will give you all the information you need to burn, and install your own Mod Chips.

Need to know how to determine the model of your PSX?  Turn it over, and look on the label.  You should see SCPH XXXX in the upper right corner.  Where XXXX is the revision of your mainboard.  The date your PSX was created is located in the bottom left corner of the label.  PSX's produced before January 1996 are referred to as the 100X/300X OLD mainboards.

PSX Disassembly Instructions:

Installation Instructions:

NOTE:
Look at the sticker on the bottom of the console.
It shows the model number of your PlayStation and looks like this: SCPH XXXX (the XXXX stands for the model number)
CAUTION: disconnect all cables and remove any discs prior to disassembly.
Keep track of where the screws and internal components go as the machine is disassembled; this will make it easier to reassemble later.

Removal of the Console Cover:
Turn the unit over and remove the black screws.
Lift the cover off.

Removal of the Laser/Motor Assembly:
Disconnect the orange ribbon cable by pulling straight up on the end of the cable, where its connected to the socket on the board. (On the SCPH 100x and SCPH 3000 series you will have to lift the black socket a little bit in order to release the ribbon cable). This will release the cable, which can then be removed, by pulling straight up (Be careful when you pull at the cable) Disconnect Laser housing power connector (3 gray + 1 white wire) by pulling straight up. Disconnect collection of rainbow colored wires by pulling straight up. Lift off the laser/motor assembly and put in a safe place.

Mounting the PIC12C508 Chip to the PU-18 Board:
Carefully bend the the pins of the chip with pliers so they are parallel with the chip. Locate the area shown on the enclosed images. Carefully glue the chip UPSIDE-DOWN on a suitable place on the mainboard. Prepare 4 isolated wires, by cutting the enclosed long wire into 4 parts. Solder the parts to Pin 1, 5, 6, 8 on the chip. Solder the other ends of the wires to the soldering points on the mainboard which are indicated by the arrows on the enclosed installation pictures. The Pins of the chip must be completely isolated from all metal parts of the mainboard and from the metal plate at the PSX bottom! (use a self-adhesive plastic sheet to isolate the chip) Re-assembly: Re-assembly is to be done exactly in reverse order.
