Hello all!

Anyone else see this auction on eBay?  Looks like some kind of credit unit for a IGT S+.  Didn't know such a thing existed??

You are bidding on

(1) USED IGT Free Play Board and Harness.

This Board allows you to add credits without any money or coins.
It attaches to the Coin Comparitor Harness.
(Come from an S+ Machine)

Used and tested good

I put a bid on it...if I win, I'll try to make more of them...I wanted to see what makes it tick...

I had a bally mpu that was modified for free play.  If you pressed change it was like putting in a quarter.    I liked it and I could always disconnect the switch to make my friends put money in.  :3- :3-

I asked around but no one seems to know what the mod was.

I'm interested to know where the green wires with the spade terminals connect to and also if the orange harness, the one not connected, is just an extension.
Eric

The Bally mod also tricks the mpu into thinking it's paying out too so you don't need a hopper.  I wonder if this thing will do that too.   SB will let us know.   I hope he wins.

yes,
If I win this thing I will make a complete schematics of it and post it up should anyone want to make one...if I have time and resources, I will fabricate some for those would like one.
-SB ? :97-  boy my name changes everyday....lol

I like SB or Stout.   

 :89-

I was also thinking that the orange harness was an extension, but it appears that the small green and yellow bundle coming off of the unit merges with one end of the orange harness. the green wires also trace back to the same connector. They merge into the orange harness at the 12 o'clock position.



SB, I wonder if it simulates the signal that the optics send to the board while still allowing normal coins to trigger the optics? :79-

I hope we'll all find out soon....believe me, this WILL get documented on NLG should I get my hands on it :89-

Somebody REALLY wants it bad.... :72- I gave up at $50.00 total....jeesh.... it isn't worth that much :96-

I wonder if it could be simple to make something like it that will work with both the S+ and S2000, I doubt the optics in the 2 are much different.

I am thinking it monitors the Coin Comparator enable signal and player button inputs. so it can trigger the coin inputs, and player inputs to the mpu.

Might be easy to create our own version(s) for the S+ and S2000.

I did notice that the S2000 does not respond to the switch on the coin optic.

Winning total was $86.25....man...I better make some units up for sale ! :72-

Even when the door is open?

If you and I could figure out how it functions.
We could make a few NLG members happy.

I should pull out the S+ and S2000 motherboard and door related diagrams

I might be incorrect but I think the optics only return 2 signals to the mpu on each.
I think I my S2000 is missing one optic on the board, 2 sets instead of 3.

Add: yes the switch does not work with door open. but it registers coins just fine with door closed.
The S2000 has nicer test screens but I have not found a way to test game play with door open

of course it would be cool if we could figure it out Foster, but for starters, I sent the seller an email asking if he knew of where I could buy one or if he knew how it worked. I also asked if he had any more.
I will be tinkering around with a voltage tester next week.
I'll be checking what exactly happens whenever I drop a coin in thru the optics....extensive digging around coming up!

My opinion is tinker on but just about forget any s-2000 action with that gizmo-Just my thought.  Who knows "frankenstein" may breathe- :97-. B.

I doubt they did anything much different logic related to coin in between the S+ and S2000
My Vision has optics from 1994 in it.

Handling the switch inputs - optical isolation IC's come to mind.
IGT probably uses them on the MPU and or I/O boards anyways.
Emulating a hopper would be harder but also nice to do.
 

Foster,

They already make something like that - here is a link to an example - http://www.egsny.com/index.html (http://www.egsny.com/index.html).  But I've never seen a coin input emulator...

Here are some pics of an actual IGT Part from a Free Pull Payroll machine, it plugs into the hopper and runs up to the coin in harness at the coin mech, this game was parted out when I got it and I was going to try and put it back together but never did, here are some pics, but it is an IGT Part

mo pics

Blueridge,
It's no fair!!!...you get all the good toys to play with!!!!! :37- :37- :37- :37- :37-    :96-

correction, I have all the good stuff that is in demand ! I bought that game as parts complete many years ago and was only a cabinet with glass, it was a free spin game where if you cashed your paycheck you got a free pull, but never found the software

If you folks are seriously interested in trying to create such a beast, you may want to send a PM to Stolistic -- he's the one who put the PE+ in MAME, and understands what happens when a coin is put into the machine (as far as what kind of communication there is between the optics and the MPU/Motherboard), at least on a PE+.  I imagine it's the same method that the S+ uses.

I think this was a remote activated credit switch and the pays were knocked off (instead of paid from hopper) with this device

Later on when you decide to hook it all up, can you show us a few pics of it installed?
I'm interested in seeing where the harness is hooked up to...
It also looks like a lot more involved , judging by the looks of that board.
Doesnt look as simple as the fleabay pic that was up for sale the other day.
Now that I see the board inside as in your photos,
I'm pretty my level of electronics knowledge isnt capable of making that. :8-
Darn, I wish I took up more electronics at school. :25-
Making boards like that would involve making up also the chips that are in it and completely wiring up some type of breadboard with quite a bit of wiring and matching components.
I dont know many people that know how to construct boards and etching in wire traces for the components.
I thinking of learning though...just for the heck of it.

Or I can let you use it and see what you can do with it when I get back

Oh man,
That would be just awesome!...I'd I.D. all the board components and go shopping at Mouser,Jameco,etc. :96-
I'll be on a soldering frenzy.  :91-
Won't take too long but I think I could do it and have a working copy posted up here.
The chips would have to go through a programmer, saved then copied onto new blanks and installed onto the boards I make.
I've located a couple of board makers around here...I'll get on the horn and see if they can make me a craploadda newly etched boards. It just takes a little time getting all the parts together really...
I love little projects like this!

Wow SB, that's fantastic. You Da Man!  :131- :131-

I'm sure that there will be a lot of members who would like to play with one of these. Thanks for spearheading this project.

I'd love to do it any day...all I would ask for is a few bucks for the components...I'll be careful where I pick up the components and such....sometimes it's better to order stuff like this straight from Japan/China,etc.
For instance, I bought like 50 LEDs last month, for around a whopping $2.25 plus $4.50 to ship.
Soldered every one of them suckers to a board that goes inside of a topper light....works perfect!
You just cant get components around North America for those prices.

2 things.
1) Newark Electronics is usually cheaper than Digi-Key and Jameco.
2) Ifyou use the company PCB 123 to manufacture boards you can download their free software which allows you to lay out your traces.
The software is not to bad for what it does.
Hope this info helps.
Thanks,
Eric

No , its is not all that dificult to have a free play IGT game... , email me
at dupuhini@runbox.com and I will send you a very simple circuit to do the job...

I built these to attract customers outside the casinos.....

SB - Is that a real cat?

Welcome aboard, It's good to have you here.

Thanks,
Wayne

I emailed ya!

ADD>>the cat IS real...not mine, but I cropped the photo. The actual full photo showed a mirror next to his right...apparently he jumped backwards and upwards... he's actually scared sh---less from seeing what he thought was another cat net to him! lol

Welcome to NLG dupuhini   :88-

I also sent you an email!   :61-

I usually just ask my wife for $10 -   

Instant free play.
 :97- :97- :97- :97- :97- :97-

Well , too many email to answer , I will post it here....

Thanks dupuhini, you saved me an email. :72-
K+  :131- :131-

dupuhini,
I couldn't find any PIC16F84AP chips, would this one work?
It doesn't have the "P" on the end....but the pin outs look the same as your schematics...

Thanks dupuhini! K+   :3-

Most programmers can load the compiled program into the device.

I didnt see any componant values other than the IC
Cap values, crystal, etc?

Yes any PIC16F84 will work at 4Mhz Crystal or Resonator...

IC2 - 78L05 voltage regulator , since V-B can run upto 9V on some machines

Q2 - 4Mhz Crystal or resonator

c1,c2 -  >10  <=22 picco farards bipolar caps

IC1 - Any PIC16F84

Thank you duphini,
I was wondering what parts to obtain! :5- :96-
When I get everything together I'll attempt to make one.... :91-

thanks dupuhini.. :131- :131-
i have a dumb ?Q, about c1,c2 capacitors #*%@ value? :103- 
what is this mean :88->>>[copy]  >10  <=22 picco farards bipolar caps..?? :99-

I believe that he means that you can use any bipolar capacitor rated at more than 10 Pico-Farads, but less than or equal to 22 Pico-Farads.

Thanks for posting the links to the parts. :71-

i got it..thank you.. :131-  statfreak..
10Pf.--22Pf.

Anyone locate the caps?

Thanks man! kudos to your sleuthing and finding out where to get these parts....!

you might need a little printed circuit board too..or pick them up at radio shk,

Has anyone built one of these yet?

Yes I have built about 14 of them , all worked first time...!

I just built one and put LED's on the output to try and monitor what happens...It seems to just cycle thru A-B-C and repeats over & over...It does not stop...Any ideas?

By cycling the a-b-c optics with the correct timimhg , it will give you a credit.
depending on the version that you flashed your pic hcip with , it will give you the correct credits
for each button press.
If you have an open or floating input in the pic where the button must be , it will repeat endless
until the state of the button changes.... , use pull-up or pull-down resistors of 4K ohm if you are simply
testing....

Thank you..that seems to work...Have you ever built one for a Sigma SG300?

The firmware for the Sigma would be verry much the same....

Depending on the Master program used....

Please provide me with the Game program number on the Sigma , and I will look into it...

According to CoinMech. the delay time between optics is 15ms and not the 150ms currently on this...The game is "Free-n-Easy"...the coin comparitor has built in optics and the SG300 does not use the separate drop optics like the SG150...Thanks in advance for any input...Maybe the files can be rewritten...Just need 1Coin and 3coin...

If you have this circut installed, this may (check with a lawyer) make your illegal slot legal as no money or tokens go in and nothing happens when you cash out. Might make a whole lot of people happy here. I know that a vendor was offering Bally Free Play machines on their website and claimed that they were legal in 49 states (no Louisiana :60-). Again, I 'm no barrister, check it out with reliable sources.

Hello,
I have an S2000 - 3-Reel, 1-Line, 3-Credit Multiplier slot machine.

I recently came across some postings regarding the plans or circuit layout of way to make you own free play board and I would like to see about getting this for my machine.

If anyone could assist me I would greatly appreciate it!

Thank you in advance…

Look back into the posts and
you will see all the links to the parts and
where to get 'em! :89-

Does this circuit work with an S2000 or a Game King?

Also, am I to understand that the credit button on the optics works ok on an S2000 as long as the door is closed?

I would test it, but my Haywire is down right now and my Deluxe doesn't have a coin in. It's always something, ha.

Thanks!

I have no idea whether the free play circuit works on an S2000 or Game King.
I understand it was made for the S+ platform.
Do you have this circuitry board?

As far as the "Service Credit" button on the coin-in optic boards -
it should be totally UN-operational when the door is closed.

No, I don't have one.
I'm willing to give it a try building one if I knew it would work on an S2000.
I may have to go the mechanical route, drop token in and route it to the coin tray instead of the hopper.
Not sure if that solves the legal aspect, but may be the only option for free play on an s2000.

When the coin comparator detects a good coin it sends a signal to the machine.
Then as the coin passes the optics the photo-transistors turns off as long as the coin is between them.
no both optics do not turn off at same time but on/off/on as the coin clear the optics.

For simplicity lets say the coin good signal changes from logic 0 to logic 1 It could be inverse as well.
Then as the coin passes by optic A it goes to logic 0 until the coin passes it but the coin also causes the optic B to go to 0, then optic A goes back logic 1, then optic B goes back to logic 1

What this tells me is that the circuit emulates the coin passing through the optics, but not through the comparator, therefore it doesn't work on an s2000 because the machine never receives a signal from the comparator... do I have that correct? sadly...

For a coin to be accepted by the S2000 the coin comparitor has signal to the machine coin is good, then the machine sees the coin pass the optics and the timings are in the acceptable range then machine accepts the coin.
If for some reason the comparator is bypassed (you can do this on a S+, not a S2000) and the machine does not get the coin ok from comparator the machine will tilt.
also if the coin takes to long to drop or someone tries to cheat the machine detects the cheat via the optics.

Think of the coin comparitor and optics working like thsi.
                                                                     _____
Coin comparitor singal (coin acceptable) ______|        |________________ Note it may be inverse for this singal I have not tested it
                                                         ______________            ________
Coin Optic A                                                                |______|               the signal drop is when coin blocks the optic.
                                                         __________________           _____
Coin Optic B                                                                      |______|
                                                      
Comparator, optics and the hopper can easily emulated by a microcontroller and a few other componants.

Like I said on earlier posts, there are some dealers who sell Bally freeplay machines. who are not sponsors here so i will not mention them.  They claim (not me) that their machines are legal in all states except LA because there is no money in and the payout is just a hopper emulator circut that emulates the payout of coins. (Again, not me, them, their statements) They claim that because of this, the machine is not a gaming/gambling device. I use tokens and really don't care. Some like credit play but I like the sound of tokens hitting the tray. Free play would be convenient but it still may not make it legal for you to have the machine in an illegal State. I think the RNG is what makes the device illegal, not coins, tokens, slugs, etc. I am not a lawyer and this is not a legal opinion/advice, look at my signature. Sorry to have to mention it but I don't want anyone to get the wrong idea about this post.

I agree, it's different from state to state on
what is considered a "Gambling Device".
Just making a machine play without tokens or bills
doesn't mean the machine is "Legal".
Some places, a bolt for a slot machine - is illegal.
Why? Because the intention of the bolt is for a slot machine
and therefore a "gambling device".   :30-
However, if the intention of the bolt is for my bicycle - then it's okay.
I would therefore argue that the intention of my
slot machine is for a toy piggybank.
Nothing more.
One could get locked up in the loony bin with red rubber walls
if they were to actually argue that in a court of law though.... :96-

I have had LEO's See my machines a few times,
They just said nice, cool, and didn't even think anything about legal or the like.

Like others on here have stated IF you are using them in illegal gaming or gambling then you will be staying at the gray bar hotel for a long time.

And some big friendly guys watching to see if you drop the soap on the floor in the shower... :96-

What makes you think that they would wait?  :25- :81- :47-  :14- :106- :18-

I thought at least they would be a little polite when dating?  :5-

That we digress again! OK, if there is a schematic for a free play board for IGT, if it is not copyrighted, command it to come forth! Or you could PM me to find out the dealers that have the Bally FP machines and if you want to contact them, fine. But I don't think they are going to reveal the source or the schemes for their circuit. They claim that their techs developed it but I don't know if that is accurate or not. If they sponsored here then I would reveal who they are. But since they don't..........well I don't think it's fair to those who do sponsor.

oh,
I've asked around...but I didn't flash any money - so therefore, I have no answers...

I've seen some pulse to Netplex stuff and it doesn't take much to make a hopper emulator.  Some of our customers are de-militarizing IGT machines by ripping out the DBA and hopper and adding either freeplay switches or Smart Card units.
