IGT Free Play Board and Harness

[dpalmi]

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. 

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

[Forrhouse]

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.

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.

[stayouttadabunker]

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 ?   boy my name changes everyday....lol

[jdkmunch]

I like SB or Stout.

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?

[stayouttadabunker]

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

[stayouttadabunker]

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

[Foster]

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.

[stayouttadabunker]

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

Even when the door is open?

[Foster]

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

[Foster]

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

[stayouttadabunker]

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!

[PWRSTROKE]

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

[Foster]

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.
 

[dpalmi]

Foster,

They already make something like that - here is a link to an example - 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

[blueridgeslots]

mo pics

[stayouttadabunker]

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

[blueridgeslots]

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

[knagl]

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.

[blueridgeslots]

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

[stayouttadabunker]

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.
Darn, I wish I took up more electronics at school.
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.
