    No. NVRAM does not affect any timed modes that you are referring too.

    It only affects very few DMD games (only when the game is turned off) that use a real time clock and which have the Midnight Madness mode and Twilight Zone (if you care about that cool feature), which actually keeps the real clock time while in attract mode. Alphanumeric games (non-DMD games) do not have a real time clock at all.

    MM is the only one in your collection that can be affected as what theLAW mentions about MM (I'm not familiar with).

    Upgrade to NVRAM. You will be glad you did. I'm installing them for every game I work on for others as a standard, minus the 5 or 6 DMD exceptions, if the owner wishes, then it is lithium batteries for those.

    Here is the way I put it to people when I work on their games. Say, I install Lithium batteries now in a game for you instead of NVRAM. Somewhere down the line, you sell the game and the new owner reads on the internet that you need to change alkaline batteries every year. Some people may not realize Lithium batteries last much longer and should not leak. Very likely what will happen is that the new owner (most likely, new to pinball ownership) will install alkaline batteries because they are cheap. So now the game is at risk yet again.

    So, I suggest that anyone who does install Lithium batteries in a game, put a label over the batteries stating "Only replace with Lithium batteries". That way the MPU board will be protected for a much longer life. New replacement boards may not be easy to find in 10+years.

    Quoted from chuckwurt:

    Does it matter though if they are in a remote battery holder?

    You would be surprised what the fumes from Alkaline batteries can do.

    Quoted from kvan99:

    NVRAM is great as long as you don't have to install the socket on the board first

    I personally installed over 150 NVRAM in my games and others and I do not even have an electric desolder station. I do have my trusty old blue manual solder sucker. I purchase a minimum of 20 NVRAM at a time. I'm here to help give the longest possible life to a MPU that I possibly can. NVRAM for a long life!!

    OP, I'll be happy to install NVRAM for you, if needed.

    Quoted from kvan99:

    You're a good man PM.

    Thank you for the kind words, Sir.

    I'm in the process of upgrading a fellow Houston collector upgrade his 45 pins to NVRAM. Lucky enough for me, 11 were DE/Sega/Whitestar games, so that was just a quick swap out. With the WPC/WPC95 games I already upgraded, I think I have 15 to go. Though, unlucky for me, he had 5 (3 are WPC95) MPU boards with Alkaline damage that I had already repaired and installed NVRAM. Here is one WPC before (speaking of fumes/leakage) and after 3/4 of the repair work was done to this point. Wish I had pictures of the other 4 boards handy, but can't seem to find them at this time. 20170408_115512 (resized).jpg20170409_111916 (resized).jpg

    Here is a Bad Cats MPU I repaired for someone who said there is no battery damage on the board. I got there and looked it over and removed the battery holder and you can still see the nasty wetness that was still under the holder. 20170311_130238 (resized).jpg

    Quoted from DaveH:

    NVRAM, hands down. Just end any trepidation on battery leakage. For games with midnight madness, every once in a while set the clock to 10 PM.
    I see so many boards damaged from batteries that leaked. It’s an expensive mess that can be prevented so easily. And there is just no need for it. Stop f$&king around and just install NVRAM. I’m saying that to everyone here. It’s the first thing I do when I get a new game.

    Amen, Brother!!

    Quoted from John_I:

    I just solder the NVRAM in place because it is permanent anyway...

    You are a brave sole. The newer NVRAM now has a 73 year retention life. What happens when you out live it? Being I install mine in a socket, I will not have to worry about seeing very well in order to just swap in another if needed. haha

    System 11_ and 11A boards should already be socketed from Williams and would use only a 6116 due to the layout of the board.

    #26 1 year ago

    Mostly, I use http://www.pinitech.com/products/cat_memory.php

    Have also bought a few from http://nvram.weebly.com/
    and even http://lockwhenlit.com/anyPin.htm

    Might even be other sources ready to use.

    Quoted from someotherguy:

    Would be nice if this was true, but it's not. Some may be socketed, haven't looked at very many in quite a few years and my spare boards are in storage - but I'm looking right now at my PinBot's 11A board and it is very much not socketed. The MPU is actually out of #597 (Millionaire) but still an 11A regardless.
    Not a huge issue to deal with if one has any soldering skills, but an obstacle for those new to the game.
    Just placed my order for Pinitech NVRAM's for all my games, looks like a nice product.

    Well, was just basing it on what I have seen. Some may have been socketed after leaving the factory. I can install NVRAM for you if you want. I live close to the Katy area if you want to bring it by.

    You did order 5101 for you other 2 games? Normally the old SS Williams games are not in a socket either.

    Great, thanks for the info everyone, extremely helpful and grateful to all!

    And....what did you decide?

    Quoted from HarryReimer:

    How long do the lithium batteries last?

    Possibly between 6 to 10 years. But you are still throwing batteries away and risking someone installing alkaline batteries in the place of them so the board is at risk yet again.
