Title: Dotmation big bang piggy bankin
Post by: newkid3 on November 18, 2015, 12:11:27 PM
Hello all, i have a big bang piggy bankin that the sound just does not seem right. The reel spin never plays when playing the game. The reel sound plays in test mode. It also seems like some other sounds dont work when you go to the dotmation board for bonus. There will be no sound at all. Here is what i found out from sound test. When i say work or dont work means if it played tune in test. Anyone have any idea what could make some of them work in test mode like reel spin but not in game play?
1-Jack pot tune (works)
2-large hit (works)
3-medium hit (works)
4-small hit (works)
5-very small hit (dont work) gives number 153 in the w7n meter window
10-signature tune (dont work)
11-jack pot loop tune (dont work)
All the rest work except 108-hopper coin

You may have mismatched game versions.  Post a picture of your mpu board with the eproms, maybe someone who has this game can compare what you have and chime in.

Something else to check would be Jumper JP2 on the mpu board. It has 2 positions, some games use 8mbit sound eproms, other games use 4mbit eproms. You can put it into the opposite position and then see if that corrects the sound problem. If not you can put it back the way it was. Sometimes people convert the machine from one game to another and have this happen. The center pin needs to connect to one or the other outside pins.

I'm pretty sure that Big Bang Piggy uses the 4mbit eproms so the jumper should have P7 Out connected to +5, which is opposite of what the photo below has.

JP2 is the small 3 pin jumper located in the far right corner area of the board, with the board's pull handles closest to you, like it would be in the card cage. The jumper has "P7", "P7 Out" and "+5" written on the board nearby.

Like Rick said, while you have your mpu board out of the machine take a clear photo of it and post it here for us to take a look. That way we can read the eprom labels and see better any problems. We love pictures here, so don't be shy about posting a few of your machine, outside with it turned on so we can see the displays, and then with the door open so we can see the insides.

Can you tell us a little about your machine? Have you had it a while and it was ok until this happened? Or did you just acquire it with this problem and are trying to get it working? Has someone tried replacing any of the software eproms or circuit boards? This will help us to figure things out.

Another thought about the sound levels-

On many of the WMS dotmation games you can separately set different sound volumes to some of the different events, they can be set so low as to appear off. In the diagnostic/setup you can set the volume level for normal machine sounds such as the tone when a coin is inserted, when a credit bet is made, and when small wins occur. You can separately set the volume for what they call a Large Hit (a win of above average amount) and a different volume setting on the Top Award Jackpot. This is 3 different sound level settings, maybe someone set some of them to a very low level. I'd go thru the diag/setup process and check the settings.

Also, if you are going thru the diagnostic/setup and trying the different sounds not all of them will do anything. The machine design allowed for a wide variety of sound events, but the particular game software installed in the machine may or may not use all of them.

Here's another curveball- the manual mentions that some jurisdictions such as Delaware required special software that had certain sound events muted, no sound. This probably isn't what you have, you can check your software jurisdiction a couple of ways, one is by decoding the jumpers on the I/O board. Another is going thru the diag/setup process and bringing up the software jurisdiction info.

Check what these guys said first, volume being an easy one, then if none of that fixes it let me know.
I just took a Big Bang Piggy Bankin kit out of one of my machine and can get you the eproms if that's the problem.

Good luck,
Bud

rokgpsman ok i changed the jumper jp2 it had no effect still no reel spin tones. So i put it back it is positioned like you said it should be. I checked the volume of all three 1 was 30 2 was 70 and 3 was 125. Plenty load when i pushed the max bet to check sound volume. Here is a pic of the game board. Bud i would not think it is the sound eproms because the sounds like reel spin works in test mode. But i could be wrong for sure.

Shoot, it is not an original, so hard to say if your sets are matched.  It is odd though that your xu2 and xu3 are different versions?
Title: Re: Dotmation big bang piggy bankin
Post by: rokgpsman on November 18, 2015, 03:28:02 PM
newkid3, what about the other information I mentioned earlier? Are you working on this machine and it is new to you, or do you know it was working ok and then something happened? I don't want to have to run down 100 different possibilities, so as much info as you can give will help.

On the sound roms U17, 18, 30, 31, two of them are nicely labeled, the other 2 are not. Looks like different times or different people have maybe worked on it? Why else would 2 of the sound eproms not be labeled when the others are? That raises my suspicion that the problem could be with the sound roms, not sure.

Are you aware there is an earlier similar WMS domation game called "Piggy Bankin'". It has similar but different software eproms. Any chance some of them got swapped into this machine by mistake? Do you have an eprom burner where you can read the sound roms and list the checksums for us to check?

Something else to be aware of. Your sound eproms have a speed rating of -120 nsec, the WMS manual says to use -100 or faster (meaning -80, -90, -100). But I've seen some machines use the -120's and work ok, may just depend on the eprom brand. But when you run down the usual and ordinary things to try you then jump to the out of the ordinary explanations.

I had one of mine where the top board had some swelled caps and the sound on all effects was very faint, no matter what volume I had it set at.
Switched out the board and worked fine.
Maybe check that too.

I've seen before where xu2 and xu3 had different version numbers on their labels. I think WMS released the software in the 2 chips independently, since the xu2 software was what determined if the game was 2 coin, 3 coin or 5 coin max bet, as well as the max jackpot win (1000 coins in this case) and the win percentage. Any of the xu2 versions for the game would work with the xu3 chip, as long as it is the same game.

I just got the machine. Trying to get it 100% everything works now but the sound. If the sounds work fine in the test mode could the eproms still be bad?  Will post more pics. It is like something is not telling the sounds to play.

Not sure, if the sound eproms work ok in Test mode then it would seem they are ok. We'd just like to confirm they are the right sound eproms and can't the way they are labeled. And the ones that are labeled say Piggy Bankin', not Big Bang Piggy Bankin', so someone unfamiliar might have burned & stuck in the wrong sound roms for that other model of game. Since the games are so similar they may sorta work. But you aren't getting distorted sound or quirky sounds. It is just no sounds during play when there should be sound, right?

The main eproms at xu2 and xu3 are Big Bang PB software, so they require Big Bang PB sound eproms. But the power on selftest is supposed to check for mismatched software. Since the sounds work ok in Test mode you'd think that the problem would be a game setting that is wrong.

You can try putting the machine in "Demo" mode. This will allow it to play normally but you don't have to insert coins and no coins are paid out. See if the sounds work or not in Demo mode. You set Demo mode thru the diag/setup procedure.

Do you have any other dotmation slot machines you can try a different set of game chips from? And can the guy you got it from provide any history, such as how it did or did not work, if any work was done to it like chip changes or board changes?

Another idea- does the dot matrix animation display work like it should? Have you looked inside the dot matrix metal box (located in the top box of the machine)? There is a power supply board on the right side and just to the left is the dotmation controller board. It has to have companion Big Bang Piggy Bankin' software in it, there are 2 eproms on the right side of the dotmation board for this. On the left side of the dotmation board is another eprom but it is usually left alone, works with all dotmation games. The dot matrix controller board has a narrow cable that runs from it down to the backplane board. I don't think any of this would affect sound but you can look it over to make sure all looks ok.

Wanted to make sure we are on the same page. I just played the machine for a while. Alot of the sounds work fine. Coin insert, when he blows a bubble, coin payout, when he laughs, when he squills, when he says i guess sweet. The only sound i know for sure that is not working is the reel spin.
Title: Re: Dotmation big bang piggy bankin
Post by: rokgpsman on November 18, 2015, 04:54:02 PM
ok, that is better than I thought, that most sounds do work ok

Here is a video I found that shows some of the machine sounds, compare it to what you are getting on your machine, esp the reel spin sound. The video is for the older Piggy Bankin' game but the sounds are the same. And there are other videos on youtube that you can watch to compare sounds.

Title: Re: Dotmation big bang piggy bankin
Post by: newkid3 on November 18, 2015, 04:57:38 PM
There are no sounds when you go into the big bang spin game. When it spins around and you play until you hit a bomb. No sound until it gives you credits. I just watched online where there is like singing and tunes a guy talking. I get none of that.

Post by: rokgpsman on November 18, 2015, 04:59:50 PM
That's called the bonus round and a lot of what happens in the bonus is controlled by the dotmation controller board. Show us a photo of the dotmation controller board. It has eproms and a couple of jumpers. Dotmation controller location is mentioned in reply#12 above.

Here is a video of the bonus round in action, on your type of Big Bang PB machine:

That's why I asked earlier in Reply #8 if you had an eprom burner. You can pop the sound eproms off the mpu board and check them with your eprom burner, do a read and get their checksum. Just doing a read will tell you if they are working, since that accesses the data in the eprom same as the mpu board does, and the checksum will tell you if they are the right ones or not for your game.

Big Bang Piggy Bankin'
CPU BOARD Sound Eproms:
u17   27c040   cksum=B000   
u18   27c040   cksum=9100
u30   27c040   cksum=8A00
u31   27c040   cksum=D000

eprom type 27c4001 is equivalent to 27c040

Yes, the audio amp is on the I/O board in the card cage and over the years the capacitors can dry out and degrade, mostly affects the electrolytic types. Since some of the sounds work ok I'd think the audio amp is ok but there may be other things on the I/O that select individual sounds (not sure), and that is what he has going on, certain sounds do not occur but others are just fine. Swapping out the boards would be a quick way to narrow down the problem if he has replacement boards or another machine available.

That would be a good way to prove if your Piggy machine mpu board and the I/O board are good. If the same sound problem happens with the boards from the Magic Lamp installed in the Piggy machine you'll know the Piggy mpu and I/O are likely ok, that something else is the cause, like eproms or something. And if the sound now works correctly you'll know one of the Piggy boards is bad. You can try the I/O board first, it will be faster & easier since there are no eproms to move around. You might want to mark the boards so you'll know which machine they came from, it is easy to mix them up in the heat of battle.

Also, when you remove the boards look for any bent pins on the 2 large board connectors that plug into the backplane.

Something to be aware of-  the backplane board (the board the mpu and I/O plug into) has a special small eeprom that stores info about the current game software in the machine on the mpu board. If you power up the machine and it has game software on the mpu that is different title than what is stored in the backplane eeprom there is a mismatch and then the machine requires a CLEAR process. You'll get a message on the front display. This shouldn't happen if you just take your Piggy roms and put them on the other mpu board and install it into the Piggy machine. But if you take a mpu with the Piggy roms and install it into the Magic Lamp machine to do some troubleshooting then a mismatch will happen, since it's backplane eeprom would still have Magic Lamp stored as the current game but the mpu would have Piggy roms.

Not to confuse the issue, just wanted you to know about this.

Don't forget to check the Jurisdiction jumpers on the IO board. I have a Magic Lamp that is NJ Jur and two 3 coin BBPB, one is Stand Jur and one is LV Jur ( Elvis Pig).

Dale are you talking about the dip switch settings for jurisdiction? I took the 6 chips out of magic lamp cpu board. Then i put the 6 chips out of bbpb board into magic lamp board. I put the magic lamp board with the bbpb chips in it into the bbpb machine. When i turned it on i got the game change 2 error code. I put the chips back in the original bbpb board and put it back in and it booted up fine. Does this tell anyone anything?
Title: Re: Dotmation big bang piggy bankin
Post by: dale on November 19, 2015, 09:17:23 AM
Hope I didn't confuse you but the jumpers are on the lower left side of the IO board and important. The dipswitches are usually all on off. After you get game change2 you need to press the RED diagnostic button. I thought you might need to clear the board first........

When you get a "game change 2" error this is just the machine telling you that it sensed a change, from you installing a different mpu board.

You just need to do what they call a "Soft Clear" to clear the ram on the mpu board just installed. You do the Soft Clear by pressing the Diag/Setup button on the front of the card cage. After a few seconds the machine will finish clearing the mpu ram. Then you press the Diag/Setup button again. Watch the digital display on the front of the machine and you will see the messages it shows.

All of the dip switches are off. When i get the game change and then hit the switch i get need clear. I dont have the ram clear chip so i could not do a full ram clear. I was wondering if the same chips being in 2 identical boards in the same machine. With it showing game change does that mean the 2nd board i am using is maybe operating different? When i say operating different. I mean maybe accessing something the first board is not doing properly.
Title: Re: Dotmation big bang piggy bankin
Post by: rokgpsman on November 19, 2015, 09:48:36 AM
Did you press the Diag/Setup button a second time? You have to press it once, then wait a few seconds for the machine to do its Soft Clear thing and press it again. I think when it says "need clear" in this case it is asking to do a Soft Clear.

If you can't get it to do a Soft Clear then yes a Hard Clear will be needed if you want to proceed with using that mpu board in the machine, and that requires the WMS CLEAR chip be installed on the mpu board. The CLEAR chip is handy to have, if you are going to be working on dotmation machines you probably need to get one.

You can try leaving the original mpu board in the machine and swap the I/O board only. Like Dale said you may need to reset the jurisdiction jumpers on the I/O board if they are different between the boards.

The dipswitches on the I/O board are only for setting up a progressive situation, they aren't used on any dotmation machines as far as I know, at least not in home use.

Ok just put chips back in 2nd board. When i put it in and turn the machine on it comes up with game change. I then hit the diag button and it goes instantly to need clear. I read in the manual if you get this error you have to do a hard reset of ram. I am pretty sure that is what i read.
Title: Re: Dotmation big bang piggy bankin
Post by: rokgpsman on November 19, 2015, 10:02:30 AM
When it goes instantly to need clear do you press the Diag button and then a few seconds later press it again? Takes 2 button presses to do a Soft Clear.

If that doesn't work then you are probably right about needing a Hard Clear. They look like this, come in different denominations for the game you use it on, like quarter, nickel, dollar. The quarter one is the most often used.

...With it showing game change does that mean the 2nd board i am using is maybe operating different? When i say operating different. I mean maybe accessing something the first board is not doing properly.

The second mpu board has Magic Lamp game data in its battery-backed up ram chip, that data does not match the data in the little eeprom chip on the backplane. So the machine senses this and asks for the ok to do a Soft Clear. The Soft Clear clears the memory and syncs the backplane eeprom and the mpu ram to the same. Shouldn't have to do a Hard Clear in this case, but if you want to or you can't get past the "need clr" message then you may have to.

Ok that makes sense. it just goes from game change to need clear. After that it does not matter what i do it will not do anything.  i guess i will have to order the ram clear chip for it. Wait wait wait. Thanks for the help. If anyone thinks of something else that could cause some sounds not to work please let me know.

So it is not that. Anyone know what i should do next? I really want to get all sounds working on it. Should i read all of the eproms. Is there some way they can be compared?
Title: Re: Dotmation big bang piggy bankin

If you read the sound eproms, calculate a 16 bit checksum and compare them to the ones posted earlier, that way you can see if your sound data is good or not.

yes, and the I/O board has the sound circuits, so it could be responsible for this problem.

You have another dotmation machine, the Magic Lamp right? I'd use it to figure out what it takes to fix the Big Bang PB machine.

First I'd prove that the sound roms you are using are ok. With a problem like this don't assume anything is ok. You still don't know for sure if those Big Bang PB sound roms you are using on both CPU boards are ok. If they are bad they'd do the same thing in the cpu board from the Magic Lamp machine, right? You can figure that out by checking their checksum with an eprom burner. Or get another set of BBPB sound roms.

Or you can put your BBPB cpu board with BBPB sound roms into the Magic Lamp machine and do whatever it takes to let the machine boot up, then test the BBPB sounds in that machine with the Diagnostic/Setup switch. If you get the same sound problem there in the Magic Lamp machine then that points to the BBPB sound roms. But if the sounds work ok then something else in the BBPB machine is causing the problem, can be found with further troubleshooting.

Did you mention earlier that you have access to an eprom burner?

That proves that the cpu board and I/O board are ok. Still doesn't prove the BBPB sound roms are ok.

All checksums on these chips end in 00. Make sure you are using the right checksum algorithm. It should be Checksum-16 and not CRC-16, having  8 digits you are probably doing a CRC-32 calculation.

Your eprom burner may use a different method to calculate a checksum, there are different ways to do it and they can produce a different checksum even on the same eprom. A common method simply adds up the data (number) stored in every location in the eprom to get a grand total, then keeps only the right hand 4 digits of the answer. This is considered good enough for most uses, but there are more elaborate checksum methods. The WMS checksum info I posted earlier uses this method. Maybe you have a setting in your eprom burner software to select which checksum method is used, information about it might be listed under Help. What eprom burner are you using?

My burner is a GQ-4X. this big BBPB board has M27c1001 eproms on it.

That's your checksum problem, the sound chips should be 27c040 or equivalent like a 27c4001. You probably selected the wrong device type on your eprom burner.

A 27c1001 is the same as a 27c010, that is the wrong chip for the sound eproms. Are you sure the sound eproms are 27c1001? If they are 27c040 or equivalent then select that device type on the GQ-4X and read them again.

The only 27c010/27c1001 eprom on the Big Bang PB cpu board is the one at U2. The sound chips U17, U18, U30, U31 are all 27c040 type or equivalent.

Also, the GQ-4X uses a compatible checksum method to those checksums posted earlier in this thread, I've used that prom burner myself. Just use the right-most 4 digits of the eight it shows.

A pic of the dotmation board

I was taking a closer look at the photo of your dotmation controller board and it looks like the eprom XU4 is not plugged into its socket very straight. Might be the camera angle or a reflection but you should check it and the eprom near it just to be sure. When inserting these 2 chips it is tight getting your fingers in there, someone may have pressed them in and hoped for the best.

Also, the jumpers JP1, JP2 near XU3, XU4 and JP4, JP5 near XU10 on my dotmation controller are set different to what you have, see photos below. You could try changing them to my jumper settings to see if that fixes the sound problem, especially the sound problem during the dotmation bonus animation. I don't have any documentation on how to set these dotmation controller board jumpers, so not sure of their function. Often when near an eprom the jumper is for selecting the capacity size of the eprom, like 8mb vs 4 mb for example. If changing your jumpers does not fix the problem then it is probably best to put them back the way they were.

EDIT- after doing more checking I found that some dotmation games like my Perfect Match use larger capacity eproms on the dotmation controller board, that's why the jumpers are set differently. That means your Big Bang PB jumpers are probably ok where they are, set to 1-2 on JP1, 2, 4, 5.

That's your problem.

Those are sound eproms for the Piggy Bankin' dotmation game, not the Big Bang Piggy Bankin'.  It's like I suggested to you back in reply #8 and #12. Your dotmation eproms and the cpu eproms xu2 and xu3 are the right ones for Big Bang PB. But someone put in the wrong sound eproms U17, U18, U30, U31. Since you have an eprom burner should have checked the sound eproms way back when. Was there a reason you didn't use your eprom burner to check the eproms when it was suggested, a couple of us giving advice had suspicions about the sound eproms due to the way they are marked. Come on man, you have an eprom burner, it just takes a few minutes to read an eprom and see if its checksum is correct.


Thread Reply #8
On the sound roms U17, 18, 30, 31, two of them are nicely labeled, the other 2 are not. Looks like different times or different people have maybe worked on it? Why else would 2 of the sound eproms not be labeled when the others are? That raises my suspicion that the problem could be with the sound roms, not sure.

Are you aware there is an earlier similar WMS domation game called "Piggy Bankin'". It has similar but different software eproms. Any chance some of them got swapped into this machine by mistake? Do you have an eprom burner where you can read the sound roms and list the checksums for us to check?

Thread Reply #12
Not sure, if the sound eproms work ok in Test mode then it would seem they are ok. We'd just like to confirm they are the right sound eproms and can't the way they are labeled. And the ones that are labeled say Piggy Bankin', not Big Bang Piggy Bankin', so someone unfamiliar might have burned & stuck in the wrong sound roms for that other model of game. Since the games are so similar they may sorta work.

The reason is i am new to this. I did not even know that the burner gave a checksum when you read a chip. I asked this back in reply number 38. "New to this. How do i calculate a 16 bit checksum? Thanks" heck i thought it was some formula. all i have ever done with it was burn a couple of chips for a pinball machine. That is why i am here asking for help. This is my first slot machine like this. I have had more mechanical ones before. Give me an em pinball with a thousand switches and 100 relays and miles of wire and i am right up town. I would have never thought the sounds would have worked at all with the wrong ones. I just did not know. Sorry for my ignorance. The one main thing that thru me off was in test mode everything work as far as sound goes. Ok so on the dotmation eproms does what my eprom burner say they are correct? If so why do the sounds not work when i go into bonus rounds like the one where it spins and stops and keeps doing that until you hit a bomb. I dont even get a peep like i mentioned earlir. Or does those sounds come from U17 U18 U30 AND U31. I dont know. When i got my first car i had no idea how to rebuild an engine. Now i am in the middle of a complete restore on a 69 camaro SS.

Install the proper set of Big Bang PB sound eproms U17,18,30,31 and your problem will go away.

Ok can you tell me are the dotmation eproms of mine that are labeled BBPB v1.01 the standard version or are they elvis. I can get a set of sound eproms for u17 18 30 31 but they are BBPB v1.00. Will these work with the dotmation eproms i have or would i have to use the BBPB v1.00 dotmation eproms also. These are mine.

The 3 coin Elvis Pig BBPB is a Standard Jurisdiction ( no jumpers), 90%. The 3 coin without Elvis is Nevada Jurisdiction ( 6-11 and 8-9) 92%. Not sure what the checksums are but maybe this could help.

Dale, was the elvis only in three coins. Mine is a two coin.

As far as I know it is only 3 coin. I have both sets, the Elvis Pig and no Elvis. Tollguy (Bill) may be the one to talk to.

Update on the ELVIS PIG. I found the Elvis Pig on my 5 coin BBPB game. XU2 903E, the only difference. It is Standard Jurisdiction.
