No matter how new your batteries are, they can leak and eat your very expensive circuit boards.

You can install remote battery packs, coin cell batteries or other devices to prevent board damage, but the ultimate solution is just replacing the regular RAM with NVRAM. No batteries to replace yearly, no losing your high scores, no leakage, and your data is good for 30 years.

Andrew "Barakandl" here on pinside, sells RAMTRON FM1608 NVRAM chips that eliminate the need for batteries.

They cost (depending on how many you buy) $8-12 USD. This makes for a VERY affordable solution.

There was some argument on the forums saying that the FM1608 was not going to work on pinball boards because of some kind of "compatibility issue", although when I looked up the specs, they seemed to be a perfect match.

So I got some chips and set off to put them to the test.

These FM1608 will work in Data East System 2, Data East System 3, Stern Whitestar, Sega, Williams System 11B / System 11C, Williams WPC, WPC-S and WPC-95 pinball machines.

Most MPU boards have sockets on their RAM chips, because this is a commonly replaced item.

Even if the board did not come from the factory with a socket, there is a good chance that at some point the RAM failed and the tech replaced the RAM and added a socket.

-

I decided that I'd do Whitewater first with the NVRAM.

I knew my Whitewater did not have a RAM socket, so by choosing it, I could document the most "difficult" RAM replacement (most owners will simply swap the RAM, no need to even remove the board from the game). Whitewater is a WPC board.

What I did not know was that the batteries I replaced last summer had already leaked.

Yep, that's a 2023 expiration code on those batteries.....

I held the board upside down over the trash and cut the battery board off with wire cutters and let it drop.

I did not want all that alkaline crud flaking off and lodging all over the board while trying to remove the batteries.

Next you need to identify the old RAM.

Here it is, the only chip not in a socket, lol.

You can see I've clipped off the battery holder to the right.

Next, I unsoldered the old RAM with my Metcal de-solder-vac station.

By using the Metcal, the old RAM simply dropped out of the board when I finished desoldering the last legs.

-

If you did not have a desoldering station, you would cut all the legs off the chip with a small pair of Diags, then remove each leg individually. That's much more work, and some would say riskier work, so a desoldering station is a good investment if you plan on doing lot's of board work in the future.

Of course we could just solder the NVRAM back to the board, just like the old RAM was installed.

But the tiny traces on these boards can only handle so may soldering/unsoldering cycles - so we install a socket.

Here I installed two rows of sockets for the NVRAM.

In 30 years when this NVRAM wears out, the next owner of this game will thank me.

Once the solder cools, clean up your flux from the back of the board.

Next you install your NVRAM.

There is a silkscreen on the board that shows the "polarity" of the chip. The silkscreen shows the notch that needs to match the chip's notch.

On well designed circuit boards, all the notches on all the chips will all face the same direction - but this is not always the case. Always check the silkscreen.

The SIPS sockets are super tight the first 10 insertions, so be very careful that the chip legs go into the center of the socket, and don't get folded under.

You can run your thumbnail along the row of legs to get them all into their sockets at the same time.

Save your old RAM.

Stick it into a block of conductive foam, or wrap it in tinfoil. RAM is static sensitive, so you don't want it just rattling around in your parts drawers without some conductive maternal around the legs.

Although you will probably switch all your games over to NVRAM, the old RAM can be good for troubleshooting a dead board that you don't want to risk killing a good chip on.

Next, put the board back in the game.

Keep your finger on the power switch in case you screwed up, and turn her on.

The game will say "Factory Settings Restored" and "Bookkeeping Totals Restored".

Play the game, enter a new high score and turn her off.

Upon return of power you will see everything stored correctly, just like you had batteries installed.

So the RAMTRON FM1608 works perfectly in pinball machines - the controversy has been settled.

Barakandl's no battery solution is certainly priced right, and works great!

Highly recommended.

I love SIP strips, I use them quite a bit. One tip to those that may want to make this a little easier on themselves.... Put the SIPs onto the legs of the chip first, and then put the whole thing in to solder. They stay in nice and tight, and you don't have to swear at the chip when you bend the legs all over hell and back again because you don't have any fingernails (Don't ask me how I know)

Awesome job Vid!!!!

These are plug and play ready as a no battery needed 6264 RAM for Data East System 2, Data East Sytem 3, Stern Whitestar, Sega games. All of those games have an IC socket from the factory pre installed. To use the FM1608 in these games it is just a matter of removing the Batteries. Removing the original 6264 SRAM. Plugging in the FM1608 NVRAM and you are done! It is no harder than replacing a ROM.

They also work in WPC games and Sys 11 B&C, but you will need to install an IC socket like Vid has shown. The real time clock will only be running while the game is turned on, so if the game has time sensitive features, they may not trigger at the right time. For most people this is minor and not having to worry about leaking batteries outweighs the loss of time / date accuracy.

This is will not be needed to be done in any games using a Data East System 2, Data East Sytem 3, Stern Whitestar, Sega, or WPC MPU. The FM1608 has the exact same voltage requirements as 6264 RAM originally used from the factory. These games are using a low voltage drop diode and start to reset before the RAM goes below the minimum voltage the manufacturer specifies.

Curious, why isn't this thread simply titled 'testing FM1608 in a pinball MPU'

It would be like reviewing the ROMs I sell vs the ones Astill sells, or GPE's LM339s vs Big Daddy's LM339s like they are any different?

If this was a product Andrew had made - example, a SMT RAMTRON on an adapter card - that would imply it was his product, and there would be a reason to compare and contrast it to the products that other sellers sell.

The controversy over whether this product would work in a pinball MPU wasn't because Andrew was selling it - it's because other NVRAM sellers had concern over compatibility. It looks like real world testing proves it will work. At least so far.

I don't know the reasoning why other sellers said it wouldn't work.

A couple other comments - definitely save that old RAM chip if you can! There are plenty of other uses of 6264s in pinball boards, and saving a couple bucks on a future needed part effectively makes the chip cost even less

Not all WPCs are directly configured with 6264s. The WPC MPU can be rejumpered to use a 62256, and some games shipped with them. I've seen 62256s in Judge Dredd, Demo Man, and IJ from the factory - and probably others.

To convert a WPC-89 MPU that is set up with a 62256 to use one of these RAMTRONs, add resistor R93 (1.5k ohm) and remove jumper W3. Failure to do this will keep the MPU from booting once it is installed.

Also, you can add WPC-S and WPC-95 to your games that are compatible.

You can leave the blocking diode there, in most of the cases that wouldn't hurt. The blocking diode has no function anymore in this setting, so why not remove it to let the FRAM run at the full supply voltage available? It isn't a big deal to remove it and replace it by a jumper.

Almost every Indiana Jones with original CPU board i have seen had a 32K8 62256 SRAM installed. I often wondered what the reason was Williams did this. Did they use the extra amount of memory or didn't they simply had no 8K8 SRAM devices available at the moment of manufacturing?? I didn't want to take the risk in the past and installed FM1808 32k8 FRAM's in those games.....

It's like those big Capacitors that they sell to stiffen up your car stereo amps.

The companies that market them, don't actually manufacture them.

They buy them, test them under load and put their label on them.

When Car Stereo Review reviews them, they don't say "2 farad capacitor review", they say "Black Lightning Megastiff Review - Black is Back!".

-
Andrew is testing each of these before shipment, so the product you are buying is his own "value added product".

If you just bought one off of Ebay from China, you could get a fake one, a remarked one, a cull or a pull.....

So it only makes sense to call this a Barakandi product.

I posted this in this thread - https://pinside.com/pinball/forum/topic/which-games-should-not-use-nvram#post-2200388 - but it bears repeating here:

The only reason not to use NVRAM on games with midnight madness modes is you want the game to keep the correct time even when off and are playing the game at midnight so that a midnight madness mode actually happens at midnight. The clock runs with NVRAM but only when the game is on. What this means is that you will get midnight madness mode every 24 hours the game is on with NVRAM, which may or may not happen at midnight. IMHO that's more fun and interesting than having to get up to play a game at midnight, which for some people isn't practical.

Search will turn up a list of machines with midnight madness modes and the discussion of the impact of using NVRAM in them. That discussion has been around the forum multiple times.
There's no technical reason to not use NVRAM in a WPC game. The only games where there is a technical reason not to use NVRAM are Gottlieb System 3 (technically this has been solved though not at a practical level) and Game Plan (and technically this *could* be done too but requires board modifications).

I guess, but it's still just a chip that hasn't been altered or improved on. Only used and tested. That test does not give any indication of life of the product even though it's likely going to last longer than most of us. I do appreciate most of your reviews and tutorials, they're really helpful as is this one as an install guide.

Damn, dude, settle down. Barakandl has some time and money invested in researching the use of these chips in various pin hardware, testing them, and seeking out and distributing a thousand or so chips. He's not making tons of cash doing this, either.

I would wager that part of what prompted this, anyhow, is Borygard's libelous statements trying to trash Barakandl for selling these chips, when Borygard is selling effectively the same thing for 3x the price (and probably at least 10x the profit.)

You will lose your old high scores - but, on the bright side, unlike batteries that don't last a year, this will hold the new ones forever once you set new ones.

So :

Pre NVRAM scores - lost.

Post NVRAM scores - held forever (well, 30 to 45 years....almost forever).

Roadshow has a feature called High Score of the Day which resets every night at midnight. Not that it really matters to me but I'm assuming that functionality will be lost.

I suspect that it might keep the daily high score for 24 hours of on-time.

That could be quite a while if you only play 1/2 hour a day.

Anyone test this?

If no one else does, I'd be happy to test and report back after installing. (Might be awhile)

One thing I'd like to add - you don't have to use the SIPs with these, as they are DIP parts. A good quality dual wipe socket will work just as well.

I know some people love the SIPs, personally, I don't care for them.

Quoted from vid1900:
Another MPU board that usually does not come from the factory with socketed RAM is the WPC-95, so let's do that one next.

This board had a 32K8 SRAM.....

even with regular ram does the RTC keep running? my games go way out of whack date/time wise if they are left off for a long period of time... I set the time on my CV when i got it and I think it thinks it's still January last I checked
