Description
The 6264 NVRam battery eliminator replaces the old battery backed SRAM which holds the settings on many pinball machines and allows for the removal of the batteries which often fail and cause damage to the circuit boards due to corrosion.
The FRAM used on these boards is non volatile meaning it does not lose its memory when power is removed, so batteries are no longer required to store the systems settings.
These boards can also be used as a replacement SRAM for 8kx8 600mil ICs such as MB8464, HM6264, SRM2064, HY6264, M5M5165, MK6264, W2465.
Williams WPC, WPC-89, WPC-S and WPC-95 – Ram location U8. If your systems uses a 62256 you can remove the 0 Ohm resistor located at W3 and install a 1.5k resistor into R93 to convert the system to using 6264 ram.
Williams System 11 revision 11B & 11C – Ram location U25. 6264 can be used by installing jumper W6 and removing jumper W5.
Stern Whitestar – Ram location U212. If the jumpers located directly below the ram is set to 32k, change the jumper to 8k to use 6264 ram.
Sega Whitestar – Ram location U212. If the jumpers located directly below the ram is set to 32k, change the jumper to 8k to use 6264 ram. “Sharkey’s Shootout requires a 62256 module”
Data East – Ram location 5D. Laser War on Data East System 1 MPU boards requires a 6116 ram module.
