This upgrade replaces the 2064, 6064, 6264 or any compatible 8K SRAM fitted to Williams, Bally, Data East & Sega/Stern Whitestar Pinball Machines. It is also suitable for any other electronic equipment that uses an equivalent SRAM requiring a battery backup.

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 damage to repair or replace the board and/or components. Once upgraded, the NVRAM will retain all your configuration settings and High Scores for many years to come.

It will work with most Data East games circa 1988 to 1994. These machines were supplied with the SRAM chip already fitted in a socket, so they are 'plug & play' with no soldering required. The SRAM is located in Socket 5D. Laser War needs a 6116 NVRAM. See other listings or contact us for details.

It will also work with most Sega/Stern Whitestar games circa 1999 to 2005. These machines were also supplied with the SRAM chip already fitted in a socket, so they are 'plug & play' with no soldering required. The SRAM is located in Socket U212. Sharkey's Shootout needs a 62256 NVRAM. See other listings or contact us for details.

On all Whitestar games, if a 62256 SRAM was factory installed, it is ‘technically’ not a bad idea to change the jumper for the memory type, 32k to the 8k setting, but the 6264 should work without this change. The jumper block ‘JP1’ is mounted directly below the SRAM chip on many of these boards, but may be a physical jumper instead of a movable switch or jumper block.

The NVRAM is suitable for most Williams System 11 games, circa 1984 to 1991, including 11B, & 11C. The 11B & 11C boards have the 28 pin holes suitable for a 6264 SRAM already, but they were factory fitted with the 24 pin 6116 SRAM. The 28 pin-out can be seen as two empty plated through holes, either side, and at the front of the 6116 SRAM. This is located at U25. Jumpers W5 & W6 will need to be changed for this upgrade as well. All Williams System 11 games were shipped from the factory with the SRAM chip soldered directly to the board. This will need to be removed before installing the NVRAM so some soldering will be required.

It is also suitable for all Williams WPC games, circa 1990 to 1998 with the SRAM chip at U8. Some Williams WPC games had the 62256 SRAM chip fitted instead of the 6264 SRAM chip. If your game is currently using a 6264 SRAM, no jumper changes are needed. The 6264 NVRAM can be used to replace the 62256 SRAM with some jumper/resistor, (R93 & W3), settings changed. All Williams WPC games were shipped from the factory with the SRAM chip soldered directly to the board. This will need to be removed before installing the NVRAM so some soldering will be required.

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.

All of the Williams boards will require the existing SRAM to be desoldered and removed from the board. A 28 pin socket will need to be installed in its place. 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 NVRAM module.

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

Each NVRAM is tested before despatch to ensure it is working correctly.

Any attempts to modify your board are AT YOUR OWN RISK.

Instructions will be supplied for all games, including SRAM locations and jumpers that may need to be changed.
