Step 1: Identifying the Modchip

Your first step should be to identify key points on your Modchip. For the Sanyo system soldering to the 7th pin on the bottom of the CD Board has been verified to work on at least 1 type of Sanyo Board system. Currently it is unclear to me whether or not there are mutliple versions of the Sanyo CD board but I have personally gotten this to work on a US system manufactured March 1997.

 

 

 

 

 

Step : 2 Checking the 0019 / 0014 Bridge

You want to make sure your chip has the 0019 point bridged as shown in the picture. Some chips will come like this by default, others will have the 0014 bridged by default. On some model Saturns this bridge does not seem to matter but on the Sanyo it is important to have the 0019 bridged.

Step : 3 Soldering Pin 7 on Sanyo CD Board

Now you need to disconect the Ribbon cable from the CD Board and the green power plug from the CD Board. Once you do this flip the CD board upside down and locate the point on the bottom of the board. You will notice this point traces back to the 7th pin on the Sanyo Branded chip on the bottom of the system. This point is much easier to solder to but you could solder directly to the pin on the chip if you prefer to do that. Connect the signal cable to this point on the bottom of the cd board. Once you make the solder join flip the CD Board back over and get it set back into the saturn correctly then go ahead and plug the green power cable back into the CD Board and then re-insert the ribbonc cable into the CD Board.

Step 4: Installing the chip. (Part 1 of 2)

You first need to identify the PC Trap Board

 

 

 

 

 

 

Now unscrew the PC trap board and cut the bracket that is holding it in place as indicated by the image. This is neccessary to make room to allow the chip to fit into the Saturn Motherboard without interference from the bracket.

 

 

Step 5: Installing the chip. (Part 2 of 2)

Now that you have made your connection with the signal cable the chip is ready to be inserted into the Saturn Motherboard. Unplug the 21 pin ribbon cable from the Saturn motherboard and plug it into the Modchip, then firmly push the modchip into the slot on the saturn motherboard (with component side facing toward the CD Board). As indicated by the red arrow, points on the chip are very close to coming into contact with the metal shielding of the Saturn. For this reason it may be neccessary to to cut away some of the shielding or line the area with electrical tape to prevent any shorts on your chip.

If your chip refuses to go in you can file down the edges of connector to get a better fit. In some instances this is the only way to get the chip to make correct contact in the slot for a successful mod.

 

Then take the 5v power wire and insert it into the second from the last point on your power board as shown. (Put in the second regaurdless of how many pins your power supply board has)
