Want to never change batteries again? This is a 5101 NVRAM Module that replaces a 5101 RAM used on Classic Bally/Stern pinball machines and Early Williams solid-state pinball machines. Once installed, no more batteries are needed! The CYPRESS chip used on this adapter is rated at 151-year data retention. Your high scores won't be going anywhere for A LONG time! One of the best-values in mods you can do to your pinball machine today! Never change batteries again or worry about them leaking and destroying your expensive MPU board!

**INCLUDES FREE 22-PIN IC SOCKET!!** No more hunting down IC sockets if you're upgrading a board that has the original RAM soldered to the board & you need to install a socket.

DUAL CE VERSION. Plug-and-Play installation on Classic Bally/Stern games (ie. DASH-17, DASH-35, MPU-100, MPU-200). Williams & Gottlieb System 80 games require modifications (see below).

Williams and Gottlieb System 80 games had their RAM soldered directly to the MPU from the factory & will need to have the existing RAM removed & a socket installed in order to use this NVRAM. It's recommended that you have board repair experience if you'll be making modifications to your MPU to use this NVRAM.

This adapter does not work with Gottlieb System 1 games.
