VLC batteries
« on: October 27, 2014, 08:42:50 AM »
I have a VLC machine model 8825. Machine works fine but I heard that there is a way to install another set of batteries or piggy back them so when the current batteries get low you won't lose memory and have to get the board reset. Chips are almost impossible to find and I heard that this could be done. Anybody know the procedure on how to do this? Thanks for any suggestions.

Yes, replacing a battery without  powering down the system can be, and is, done in most any electrical or electronic scenario, not just slot machines.  The process is simply to insert a new one in parallel with the old one before disconnecting the old battery.

There is no serious electrical issue; the problems encountered are always mechanical. For each specific situation, you need to figure out how to solder, clamp, crimp, screw, or otherwise connect the (or a) new battery “around” the old one, so both batteries’ + ends are connected together and ditto their – ends. This may require some head-scratching on your part as every machine is different; and you may need  TWO fresh batteries, only one of which will remain in place as the permanent replacement; here are two examples from my past:

1.   Flashlight-style D-cell snapped into a spring-loaded battery holder.  I soldered wires with alligator clips to a new battery and clipped it in place around the existing battery temporarily. That allowed me to remove the old battery and snap in a new one, and then unclip & remove the temporary battery.

2.   Battery with wire leads soldered onto PCB. Temporarily soldered a replacement at thru-board holes further out on the power traces; unsoldered the old battery and soldered in a new one; then removed the temporary one so I could slide the board back into the machine.

Note that, except in the unlikely event of a rechargeable battery, only two electrical characteristics are really required for a replacement, permanent or temporary:

1.   Voltage: if the battery in place is 5 volts, the replacement MUST BE 5 volts. Zero exceptions. This is the prime requirement.

2.   Amperage or Capacity: most small batteries will have a rating in MilliAmp-Hours or MAH. The replacement should be at least as large, to assure it can deliver enough current to keep the system operating. However, there is no limit on how much larger it can be. If, for example, you are working on a 12-volt battery the size of a quarter, there is no reason you cannot replace it with the 25-pound 12-volt battery out of your ’57 Cadillac.

  The bottom line here is that you do not need to replace the original battery with an identical unit, if it is not available or if doing so will simply shift the same problem out a year or two. Just make sure it’s the same voltage, and at least as big.

I would recommend you be reasonably quick about the job. It is just possible for an old dead battery to suck the life out of a fresh new battery. Don’t leave an old and a new battery connected together in parallel any longer than necessary, and certainly not overnight.

Not all circuit boards with backup batteries need to avoid a power-down during battery replacement. In most cases, only active data (like credits or history) will be lost, as the real game program is permanently in PROM. But there were lots of weird little companies, with off-the-wall ideas, especially in the early “transitional” days of electronics.  If you’re not absolutely sure, don’t take the chance: parallel the old battery before swapping it out.

Finally, replacement assumes there is enough juice left in the battery to keep the system alive, even if just barely. If the old battery is dead, or weak enough to have permitted the system to flicker or die, it’s too late:  and good luck with that!

Vette6048 in your post yesterday you mentioned that you had changed some batteries already. If you have, trying piggy backing other batteries will not work. I have the same machine 8825. The last time my batteries went dead I had sent the board to Worldwide Gaming and they fixed it. Not sure if they are still doing them. It was 2 years ago. Good luck!

I think Worldwide Gaming does not do it anymore. I will double check. The last person that helped me with my board was a person named Buddy from Texas. He fixed it fine and I had no problems until I changed the 3 pancake batteries(big mistake). I believe he goes by the name The Slot Doc. I am trying to reach out to him but I have had no success. I don't want to give up on the machine yet but I will wait and see if anybody else has the zero clear chip. .Correct me if I am wrong but these clear chips cannot be copied. Am I correct?

Unfortunately, that is correct. Video Lottery Corp was very tight about retaining control, if not actual ownership.
Clear chip software was specifically made to prevent copying. And now that IGT owns what's left of VLC, what little
support there ever was is gone. They not only have zero interest in supporting private "hobby" owners, they seem
to actually be hostile to us. As for Worldwide support, they have specifically decided to cease support, whatever the reason.
It would not surprise me to learn that IGT has quietly "leaned on them."

I'd give a tizzy to know who has which clear chips & related equipment, and if they'd be willing to sell them to a single servicer.
For instance, where are the clear chips etc previously used by Worldwide? Did they hand them over to IGT...? :sherlock:

I guess if I have to give up on this I will. I agree with you on where are some of those clear chips Worldwide Gaming had. Its a funny thing back in May of this year I was in New Orleans visiting Bourboun Street and believe it or not some of their bars have VLC machines in them and their are two small casinos in downtown Las Vegas that still have VLC machines. I seen them with my own eyes. Maybe I will part out the machine along with the extra boards I have for the machine and list them on Ebay. Like you mentioned before there are clear chips still floating around its just where are they floating around. Thanks for the info on the VLC. You know those 2 casinos in Vegas have to have those chips to keep those machines running. Amazing they can send robots to Mars but cannot find a way to copy these chips. Have a great day!!

Just one more question. If I would have kept the machine on while I was changing the 3 pancake batteries(one at a time) do you think I would have saved the memory or would I have still lost it? What's your opinion?

Yes, in  all likelihood that would have worked, providing the batteries were not already dead, making the entire issue already too late.
The problem is physical: would it have been  possible to reach & replace the batteries with the board
in place and operating? Extremely difficult in most computers with main logic board in some kind of box;
and slot machines always surround the boards with a steel Faraday cage. I've never had the chance to personally play
with your model of machine, but unless it's wildly different from every other it would be impossible to reach the
batteries with the machine in place.

Vette, I wish I could help derail this machine's trip to the scrapheap, but you've hit the same brick wall that so many other VLC owners have.
Unless some local owner of a VLC "fleet" needs a parts corpse, or an NLG member with chips & a heart is watching, you're probably out of luck.
I'd love to have her even with all electronics & monitor stripped out, but you're too far away from me to pick up.

But if I may request on behalf of many other NLG poor schmucks proud owners, please please  PLEASE post photos of your machine, inside & out, before you strip her. I'll make sure they get posted for archiving with your credit.

I have had a few people ask me about fixing a VLC, but I could not help them. It would be nice if this persons name and contact information could be brought here to NLG. I'm sure we could get them some business if they are interested.. I my self have walked away from them just because I didn't think anyone was working on them or had the knowledge to fix them..

Great news  :yes: :dancing_2: Another question to ask is he able to fix the 8725? That is the previous model before the 8825.

Can someone tell us which is the RAM Battery in Model 8724?  Is it the pancake battery 2032 or the Dallas DS1260-100 or is there another battery in there that we are not seeing.  We replaced both of these batteries but still have a message reading " Reset Fail 12  - Back-up Ram #2 Battery low." 

Also, was the name ever posted of who helped fix the battery issue?  I'm not having the same problem but it is a battery error message - 36 Main Ram Battery Low.  Any help I could get would be great.

He never posted who fixed his board. I would also like to know. He did mention in his last post it was the same person that had fixed it for him before. I think he is referring to Slot Doc.                                                                                                                                                                                                                                                                            "The last person that helped me with my board was a person named Buddy from Texas.

Hi,

Here's what my 8825 says.
The machine has a damaged touchscreen CRT and I'm hoping to connect this LCD touchscreen.
The original CRT is a Philips brand so I was hoping a Philips brand LCD would work. Got the display working as shown in the photo but am struggling with the touchscreen wiring.

The battery low message bothers me a bit from what I'm reading. I'm hoping I won't need a clear chip cuz it still shows credits?
Any thoughts?
Thanks,

Todd

Sorry Larry,

I couldn't get mine to work.
I parted it out and used the parts for other machines.
Kinda sad. I really like the games and hated that parts and information is nonexistent.
I wish you better luck than I had.
Later,

Todd

Larry, Sorry for the bad news as far as I know there is no longer support for the model 87_ _ series. A clear chip is needed most of the time to bring these back to life. These chips are not out there. If it was the 8825 there are a few folks that can do those. Good Luck

Post a pic of your board. The 3 coin batteries should be on top.
