NVRAM Module for Gottlieb Sys3

No More Batteries!

This is a premium quality nonvolatile RAM (NVRAM) Replacement for Gottlieb System 3 Pinball Machines. Replaces the 6116 / 6264 RAM at U3 on an original Gottlieb System 3 MPU board. Absolutely no batteries are needed to retain your high scores or game settings, you can remove them from your game. Machine pin headers are used on this module which are very durable and won't damage your socket at all.


Please note that upgrading to nvram on Gottlieb System 3 MPUs will require modification of the MPU board as noted below.

  1. Remove the Dallas 1210 chip marked "U6" on the board
  2. Add two wire jumpers at the U6 footprint per instructions
  3. Remove the soldered RAM at U3 and install the 28-pin IC socket in its place
  4. Remove lithium coin cell battery from board
  5. If the board was previously using a 6116 (24-pin) RAM, swap the JP3 wire jumper to the JP4 position
  6. Install the new NVRAM into the IC socket, making sure to orient the notch of the chip properly

If you don't have soldering experience or aren't comfortable modifying your board (AT YOUR OWN RISK) then you should hire a professional to do this upgrade for you or leave your board as-is and replace the lithium battery instead if your game is no longer holding high scores. The Gottlieb System 3 boards have thin traces and are a bit more fragile than some boards, so you MUST have decent soldering equipment and technique for successful installation of the NVRAM.

Unfortunately battery corrosion damage is much too common in games that used alkaline batteries for powering the RAM when the pinball machine is off. Many people have reported that even new batteries from major brands can sometimes leak after a year or two for no apparent reason. The corrosive alkaline can leak or wick into the board and over time will destroy the copper traces on the board and any ICs it comes in contact with. Don't let this happen to your game!
