The Nintendo Entertainment System, easily one of the most iconic and leading gaming console from the 80’s selling into the millions across America, capturing the imaginations of children while firmly grasping at the wallets of parents. For every coin collected, every duck shot, and for every Princess saved, the Nintendo Entertainment System has filled me with great memories including strange gaming rituals like blowing into the cartridges, clicking up and down and hitting power and reset. Wonky rituals that I do just so I can play the damn thing. As popular as the NES was, Nintendo really cheaped out on the one main component that actually have the console work: the 72-pin connector.
So what is the 72-pin connector?
This project is quite simple because all you need are three things.
- NES console
- Brand new 72-Pin Connector
- One long thing screwdriver, preferably a Phillips. (Though I’m using a flat head tweaker screwdriver)
Flip the console over and remove the six (6) screws, then separate the top half from the base.
There is an RF shield covering the main motherboard. Remove the total of eight (8) screws and set them aside in your container.
There may be a discrepancy in the amount of screws at this stage. One or even two of these screws maybe underneath the shielding, depending on your console revision. They will still need to be removed.
This is just a rear view of the two screws holding the RF shielding for reference.
Remember, place your screws in another separate container. Lift straight up to remove the RF shielding. Set aside.
Spin the console around so the back in facing you. Locate the four (4) screws near the 72-Pin connector and unscrew. Be mindful the size of these screws. One is longer than the other. Place the screws in a separate container.
Locate the two screws near the front of the tray near the spring. Remove the screws and set aside.
At this point, there is only two (2) screws near the audio/video board that is keeping the motherboard attached to the bottom casing. Unscrew and set the screws aside.
You should now be able to remove the motherboard from the bottom casing. You will need to have the motherboard loose so you can separate the tray mechanism from the 72-Pin connector.
*With the connector off, you can use some rubbing alcohol and cotton swabs to clean the edge connector.
