Nonvolatile RAM replacement for Williams System 11B/11C & Data East pinball machines that use the 6064, 6264 or 2064 RAM chip. Eliminates the need for batteries to save your configuration / high scores. You'll no longer have to worry about leaking batteries, checking batteries each year or running the machine every few weeks or months to charge a battery backup capacitor. I can build a fairly large quantity of these with the parts I have on-hand and price will get better if larger quantity is being ordered.
This NVRAM is a very easy swap-out on Data East Machines. For Williams Machines, the task becomes a bit more difficult. Please read the "More Information" section below for details.

-- MORE INFORMATION --
On Data East machines, if you look at the board, usually there is silkscreen writing on the board going horizontally with numbers and vertically with letters. The RAM is at position 5-D, right under the game EPROM. From my experience thus far, all Data East MPU boards should have had a socket installed for the RAM from the factory and use either 6064 or 6264 RAM. Always good to double-check there's a socket & that the RAM is 6064, 6264 anyway just to be safe. That means this NVRAM replacement is a very quick replacement on Data East machines. Remove the existing RAM from the socket, remove the batteries, then replace with the NVRAM adapter.
Williams machines are a different story since they don't appear to have used sockets on their RAM chips (saved them money I guess). Instead the RAM is soldered directly to the board, so unless someone's already replaced faulty RAM & installed a socket, installing NVRAM won't be an easy swap-out. If you have a Williams System 11B or System 11C MPU board the existing RAM will either be 6116 or 6264 at "U25".. and if it's 6116 there are jumper changes you can do to the board to convert to 6264 RAM. From my understanding Williams 11A MPU boards (F-14, Fire!, Pin-bot, Millionaire) use 6116 RAM and can't be configured for the 6264 RAM.. Lindsey makes a 6116 NVRAM adapter you can buy at Pinforge.com if you have one of a System 11A board or don't wish to change jumper settings on your System 11B/C boards. Williams WPC also has RAM soldered directly to the board. What does all this mean? Probably that if your game is working perfectly & you have no reason to pull the boards --AND-- unless you *really* hate the idea of remote battery holders it's probably best to just leave the existing RAM & use remote battery holders than disturb the board.
Hope this helps answer questions for everyone. Rule of thumb, Data East = easy swap...... Williams = cut out existing RAM, install socket, install NVRAM (except on System 11A which won't work with this 6264 NVRAM adapter).
