I just wanted to let you know about a great little product that Rob Anthony sells. It is called “anyPin NVRAM”. It eliminates the need for batteries in your pinball machine. It is pretty great because now I never have to worry about my batteries leaking or my precious high scores getting lost due to a battery failure. I just installed it tonight in my Funhouse and I could not be happier.
Another cool thing about this chip is that if you have the DIP switch settings incorrectly, it will not harm the chip or your board, it just does not work. You can simply power it off change the DIP settings and power it back on.
