Help finding the right chip

[poppo]

Before he does that, has anyone here ever tried installing a 3-reel SP/SS setup in a game with four reels and a 4-reel harness?

I would speculate that a 3 reel game would work fine because it would not be looking for the 4th reel. Unlike using a 4 reel game with a 3 reel setup where it would look for the reel and not find it, and error out.

But now we may be back to page 2 of this thread.

However, after looking at that board more carefully I have a suggestion.

The RS chip is a 256k chip and your jumpers are properly set for a 256k chip. The SET chip is a 512k chip. Try the SET015 again, but this time move the jumper on E15 and E16 from the inner two pins to the outer two pins (E15 and blank). This jumper is located right above and to the left of the top of the Game chip socket.

Why didn't I think of that? Oh wait...

Anyone know what size the RS chips are? What about that jumper by the game chip. Maybe it's set for a smaller size eprom than the set chip you are using (because it's a S chip).

I'm not so sure. It might behave that way if the fourth reel were disconnected but if not, I'd expect an error. At this point it's all speculation since we've never tried it.

The funny thing is, you answered the question in the next post.  

RS chips are 256k.

Of course I missed actually using the info.

The board that SB spotted may need closer investigation

The board is a meter board and it does tick when a bill is inserted even though the credits don't show upon the machine. As for the 2 pin connector there is nothing I can see to plug into it. Keep in mind that nothing has changed on that side of things and it did work before the board change.

As Poppo suggested if this is a chip from a S machine it wont have built in support for a BV in the SW.

Before reading these last few post, I installed a RS 3280 chip on a S+ board. All I got out of it was stiff reels. NO display, no errors, no nothing. I pressed the test button and turned the key, nothing.

Reinstalled the SP and SS chips and still had my credits on the machine

[Mirage_Chaser]

Well switching the jumper had no effect. With the set chip in power on nothing happens. Bummer.


I had such hope.

[poppo]

Well, I still suggest using a clear and trying to set it up with a standard S+ game chip set. Process of elimination. We need to verify once and for all if a SET has anything to do with the problem. And TZtech seems to agree that a RS chip does not support a BV in software. If so, the set will do nothing. Only one way to find out for sure.

Even if the game tilted due to the 4 reels (which I doubt since people have gone as far as pulling the spare reel driver chip), it should get you far enough to use a SET to enable the BV and denomination.

Another option is to put this MPU and motherboard in another machine (with S+ chips) and get it up and running with a BV, then put them back in this one.

I really think the SET is a red herring, but I have been wrong before.  

Aslo, due to Buzz's test, is it possible this is a 'special' S+ MPU that has been modified somehow to work with RS chips? Again, too many variables and IMO you need to use process of elimination.

[stayouttadabunker]

I was just looking at that photo of the MPU.
I noticed that the 1st reel resistor has been changed.
Not that it has anything to do with the MPU not booting up
but the board DOES look almost exactly like a 10MHz S+ MPU !!!

I do not see any modifications to it at all.
There's not a whole lot of 4 reeler S+ reel chips floating around
so he's going to HAVE to make this RS chip work....Arghhh!!

Since this is a live casino in Antigua - why isn't there
any support for this machine through IGT?

In any event, I'd be swapping MPU's to try an set the
motherboard eprom via a SET chip to enable the BV then
switching back to the RS chip with
the reel chip socket jumper in the correct position.

I'd also be making sure the battery is fresher
than those 20 year old green and white battery in there...

[StatFreak]

There is one other mod Bunker. The stepper motor drivers have metal heat sink wings. I can't read the numbers from the picture, but I suspect that they are different due to the size of the stepper motors.

<ADD> The DUART is missing from U27/U18 (socket ID depends on the board), but it's used for serial communication and wouldn't affect the BV.

It's also not clear why the RS chip is currently working in the machine. I would be leery of doing a full clear or installing an SP/SS setup in that board, especially since Buzz's basic test of an RS chip didn't work. It's possible  that an RS chip might only work after a full clear (completely clearing the EEPROM and CMOS of any data structure which might be incompatible with the RS program.) However, what if that's not the case and he can't get the RS chip to work after setting up an SS/SP configuration?


If TZtech is correct and the RS simply won't support a BV through a normal setup, then the machine is already working as designed and the right course would be to investigate the extra board and how the BV communicates credits to the machine.

[stayouttadabunker]

The "Ticking Sound" when he puts money into the BV signifies to me
that the small board behind the button deck is the relay itself -
clacking credits somehow to the MPU inside it's plastic case?

I trust TZ's statement in that the RS does not support BV's
However, that little board probably does what the S+ MPU's where
able to do later on board revisions -
that is, to be able to work with BV's.

That little board is a specially made IGT board which we've never seen.
Plus, NONE of us has ever even thought of trying a RS chip in an S+ MPU.

We're in un-charted waters here.
Since this machine is in a live casino - I'd be on the handle
calling IGT and talking to a support tech.

[Buzz]

Go back and look at the original post, at that time the board had two chips installed (" SS055 Mech RS3050 ") now it has one.     Where did the SS055 disappear to ?   When I did my little experiment, I didn't have a SS chip installed.

Why was the original board replaced ??

[stayouttadabunker]

He's missing the reel chip in all of the pictures actually.
One of the pictures, the board is upside down but still missing the reel chip.
I think Statfreak took it out while I was golfing! 

I do hope the reelchip is not laying on the floor somewhere...lol

Buzz, DID you put the RS chip into the SP socket or the SS socket?
I'm wondering.
This guys picture of the MPU and what's in the sockets is of so low resolution (fuzzy) -
I can't make out anything label-wise.

[Buzz]

I just gave it a try with the RS 2380 and what ever the DDD SS chip is, same results, stiff reels and no display.

I'm thinking the IGT Man ( aka Ruden ) is having a ball.  or someone just like him ! 

[stayouttadabunker]

Please don't tell me we're on a wild goose chase!!!?!?!?!?!
We have the capabilities of checking out his IP address right? 

[Buzz]

Bunker your talking to the wrong guy.  I just found out last week where the off and on button is on my PC.   

[poppo]

I do believe that

My money is it's a loose wire in that red and white connector housing on that little board we're talking about.
We hear the "clicking" but that's it.
No communo with the MPU-oh...

[Mirage_Chaser]

No wild goose chase folks. My original post includes both numbers found on one chip. The pictures are from the board as it is now currently running in the machine.

The IGT board with the relay on it is a meter board and the ticking is the meter changing because a bill has been accepted. The board is operating as it should.

I can include a higher res photo of what ever you like all you need do is ask.

As far as IGT support goes they wont support anything older than s2000's these days. Also we are to small to get any real response.

[stayouttadabunker]

okay good, is the machine running now?
If not, what exactly is wrong right now as we stand?

On a side note, the other night when I tested the SET chip without a reel chip, I put the original MPU back in and when I powered up the machine, my siren and strobe mod (using the bell circuit) went off as soon as I turned the machine on. I was   for a while trying to figure out what was going on. It even did it with the MPU out. What had happened was the single wire connector I had on pin 2 (the switched ground) of the bell connector of the motherboard had not only come off, but had managed to contact pin 1 (24vac). I have no idea how it managed to do that since I was not even near that connector. The moral of the story is that it is not difficult to disconnect something accidentally just changing out a MPU. In this case the motherboard was swapped too. So no telling what may have gotten jarred loose in the process.

[poppo]

My understanding is the only problem (same as the very beginning) is the BV will take a bill, but not add credits.

[Mirage_Chaser]

It is running right now, all that is wrong is that it is stealing bills. And that started after the MPU and Backplane were replaced.

[Mirage_Chaser]

My understanding is the only problem (same as the very beginning) is the BV will take a bill, but not add credits.

Exactly!

Both boards (the MPU and backplane) that are now in the machine are from the same game. One I had in storage and it also happens to be a 4 reel game but it is not equipped with a BA

Thus I expect that I need to enable the BA and set the Denom but my 15 set chip does jack squat when I tried it (multiple times with the jumper in both positions)

[poppo]

How about a picture of the coin-in mechanism. Maybe we can work this in reverse and see if there is some add on to simulate coins in.

I'm still willing to bet that a set chip has nothing to do with this BV and RS chip. As already noted it's taking bills so it's not relying on the MPU to enable it (i.e. let it take bills).
