NVRAM board replaces 6116 SRAM chip, no batteries necessary Arcade or damaged tracesBatteries, oh, batteries. The damage that you do. This product simply replaces the 6116 SRAM chip. You can plug it into a socket, or solder it in directly. If the socket, it MUST be a new one. This part will not repair an MPU that has other problems, or damaged traces. You must know what you are doing and have a working board first. You get a 60 day warranty with replacement only.
