The Dual CE 5101 NVRAM upgrade replaces the 5101 or equivalent SRAM fitted to the Bally Classic, (Dash 17, 35 & 133), Stern Classic, (MPU-100 & MPU-200), Zaccaria Generation 1, Gottlieb System 80 80A, 80B as well as the Williams System 3 thru 7 games. All the boards except the Stern MPU-200, require 1 x 5101 NVRAM. The MPU-200 boards will need two NVRAMs. There are two options available, with, or without a 22 pin IC Socket. It is also suitable for any other electronic equipment that uses the 5101 SRAM with a battery backup.

It WILL NOT work with Atari machines, Gottlieb Systems 1 & 3, Zaccaria Gen 2 and Stern SAM.

By upgrading to NVRAM you will never have to replace the batteries again, and neither will you have to worry about battery leakage which can cause £100's of pounds damage to repair or replace the board and/or components. Once upgraded, the NVRAM will retain all of your configuration settings and High Scores for many years to come.

The Bally and Stern Classic games, (Socket U8), and Zaccaria Games, (socket IC7), were supplied with the SRAM chip already fitted in a socket so they are 'plug & play' with no soldering required.
 
All Williams System 3 thru 7 series and Gottlieb System 80, 80A and 80B games were shipped from the factory with the SRAM chip soldered directly to the board. This will need to be removed before installing the new NVRAM so some soldering will be required. On the Williams boards, the SRAM is located at U19 and on the Gottleib System 80 Boards, at Z5. If you do not have proper equipment or experience to desolder ICs and install a socket, this mod may not be for you as some of these boards have delicate traces. Please be aware of this and seek technical advice before purchasing the Dual CE 5101 NVRAM module. Unfortunately, we are unable carry out this work.

On some machines, the Real-time clock for specialist functions or other time-sensitive modes will not work correctly. These include, but are not limited to... WHO Dunnit, Dirty Harry, Johnny Mnemonic, Congo, Junk Yard, Theatre of Magic, NBA Fastbreak, Creature From the Black Lagoon and Twilight Zone. There are some Easter Eggs on Bride of Pinbot that require the correct time as well.

If you have any doubts, before ordering, please contact us with the name of your machine and the part number printed on the SRAM chip. We will check and confirm if this upgrade will work.

The Ultimate NVRAM is available in the 5101, 6116 or 6264 formats only.
