This upgrade replaces a 2016, 4016, 6116, 9128 or compatible pinout 2K x 8 SRAM fitted to Bally 6803, Williams System 9, 11, 11A, 11B and 11C games, & Data East 'Laser War' game.

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.  It is also suitable for any other electronic equipment that uses the 6116 SRAM with a battery backup.

The Bally 6803 games, (Socket U4), and Data East 'Laser War' game, (socket 5D), were supplied with the SRAM chip already fitted in a socket so they are 'plug & play' with no soldering required. Other Data East games will need the 6264 NVRAM upgrade. See other listings or contact us for details.
 
All Williams System 9 & 11 series 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 System 9 boards, the SRAM is located at U18 and on the System 11 boards, at U25. On some System 11B & 11C boards, a 28 pin SRAM may have already been fitted. This mod will not work with those boards so a 6264 NVRAM will be required. See other listings or contact us for details.

As all of the Williams boards will require the existing SRAM to be desoldered and removed from the board, 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 6116 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.
