Here's a cheat "bug" I found on one of my Jennings 400 machines. There were two of these, one on the left reel, one on the right. They lined up with the jackpot wins.

Well a picture is worth a thousand words. That IS a bug for sure, Different species than the one that I saw but it will have the same effect. NO Jackpot. Your situation is interesting. All of the cuts on the reel disk look to be the same depth. The cuts on the Bally EM's are very different. Also I would bet that your game was operated on a site where the house was a crooked as the letter S. To have a bug on BOTH the first and last reel means the owner was a cheap skate.

Thanks for the pictures

And here I thought the player of the slot machine would be the one to try and cheat?

So there is no way for the machine to hit a jackpot?

See, I did learn something.

Are you close to Long Island? I'm on the south shore side in Nassau County.

The left reel had the blocker placed on the TRIPLE BAR symbol (you can see it would align with the window in that image) and the right reel had the blocker on the 7 (the only 7 on that reel). So, in the casino environment, the machine would NEVER hit on three triple-bars, nor three 7's. It'd slip right past which would give the illusion that the player "almost" hit.

I acquired three machines from the same casino, not sure of the casino name, but they were in operation in the late 70's and taken out around 1981 or so. Two of the three machines I bought had the same blockers installed on the same symbols.

The 400 series Jennings machine used TTL logic for its reel control, just before microprocessors became part of the design. So, cheating the reels went un-detected by the machine's electronics.

You can't do this with the microprocessor based machines though, since the logic dictates exactly where the reel will stop, and if it doesn't stop where it's expected, it'll set a TILT and shut down.

The casinos which used those blockers must have been real cheapskates or just plain greedy! How often would a player hit three 7's anyway? Or three triple bars? The odds are so small that a win would look good to other players.

really don't think any real casino would use them , they get checked by the casino commision alot

ramegoom · « **Reply #46 on:** November 25, 2014, 06:58:54 PM »

My guess would be that the Jennings machines were on a cruise ship casino. Figuring, you're on the ship, you like to play, and where ya gonna run to?

Gooch:

Sorry, your question slipped past me. I am in Rockland County. I grew up on Long Island though. Thanks to this group I have met some great folks. I am surprised to find more and more collectors in the NYC area. We should have a get together.

As far as the bugs, they were standard parts of the thousands of machines that operated in the back rooms of corner grocery stores all over the city. An OPERATOR had a ROUTE of about 5-10 stores with 2-3 slot machines each. Did not want to make too much noise or draw too much attention to the back room activity. The grocery owner got a small piece of the action while the operator, if you know what I mean, got the lions share of the profits. Many of these games have heavy hasps and burglar bars drilled into the cabinet to prevent the cheated and now poor player from helping him or herself. These bugged games were also VERY common as rental units at local fairs and fund raisers. If you ask me how I know so much about this underworld stuff. I will tell you that I read a lot. Happy healthy Holiday to all :-)

Folks:

I am amazed how much information I have been provided with in so short a time being on here.

Rockland County isnpt that far away at all!

I guess you got the snow tonight, all we got was rain.

You can have my share f the snow.

Thank you all for helping me out, I will soon attempt to use my Dremel Tool and grind out the two bridges on the reel.

Happy Thanksgiving to all.

Dear Ramegoom,
PLEASE check your picture size as posted on Page 3 here.
Myself and some others cannot get on that page, and I suspect your pics are way too large.
Would you kindly shrink them, or pull them off for a day or two so that we can see if that is the problem or not?
Thanks
OldReno

This issue has been resolved. Reply #40 by ramegoom had two 8 MB photos embedded in it, causing the page to load very slowly even on a fast internet connection. ramegoom, I removed the hotlinks of the images to your website, resized the pictures to a more web-friendly size, and then used the "Attachments and other options" section of the post/reply page to upload the smaller images to your post. You can hotlink to images you're hosting yourself in the future if you'd like, but for the sake of everyone trying to view them (and for your own server's bandwidth!) please resize them to a web-friendly file size first. Thanks!

As to the topic at hand, I have seen similar "stoppers" welded on to the payout teeth of some older mechanical machines, as well as some that were screwed on in place to prevent one or more of the reels from stopping on the jackpot symbol. A friend of mine told me the technical term for them, but it escapes me at the moment...

Update:

I removed the left reel and removed the 3 brazed "cheats" by grinding them out. I cleaned the reel up and deburred the reel and put the machine back together to try it out.
Lo and behold, all three reels work now.

The only major lingering issue is the hopper now empties itself when ever any win is made. The hopper just keeps spitting out quarters until it resets itself. It used to pay out properly. I checked the hopper and found the knife assy. a little bit loose and wobbly. Tightening the two hex head mounting screws fixed the quartersso they are lifting the roller like it should.

How do I attack the pay out problem? Is there any place in particular to start?
One issue goes away another pops up. Just like the Wack-a-mole game.

One other dumb question? It is talked about replacing the rubber disk with a pencil eraser. Where is this disk located on the hopper?

I can't seem to find it?

Thank you.

check and see if wiper is stepping up as coins go under roller and make sure its a 25cent hopper

Amechanic · « **Reply #56 on:** November 28, 2014, 06:27:18 PM »

The payout disk & wiper board assembly are usually a seperate unit. They are usually in the lower right rear corner, but I have seen some located in the top feature box. Make sure your hopper is counting every coin that passes under the roller. You can check the operation of the hoppers switch with a VOM set to ohms. You should see the switch open and close with every coin passing under the roller..

Ladies and guys this machine has now got a new PROUD owner (me) who hopes to get it working in the near future. I had started a post but it's in the forum (http://newlifegames.com/nlg/index.php?topic=4558.0) so I thought I move over to this existing thread.

I have it accepting all 5 coins, handle works, reel spin and stop. Not sure if Winner Paid light actually light up on payout or not, I'll check Monday to see if bulb is bad/power to socket when Pays are hit. Problem: the hopper continues to run (runaway hopper) on every win. If I manually operate the coin out roller arm on the hopper it tilts the machine. The tilt only happens when the lower set of contacts make, if I operate the arm only enough to break the top set the hopper continues to run.

I have a missing wire to one terminal of a coil in the top box (see pic). The orange is 50v, if I connect Yellow (neutral) the coil does operate. Amechanic thinks he may have a feature unit similar to mine and trace the wire down.

I have other pictures if needed.

If anyone can/wants to help I could sure use it.

Thanks
Bob

OldReno · « **Reply #58 on:** December 21, 2014, 12:01:51 AM »

So does it run away with 1 coin played, or 5 coins played
A machine can pay fine on 1 coin, but runaway on more than one... When it kicks out coins, do they hit the coin out roller? Does the payboard step up at all?
Ooopps, sorry, I see there are more comments on this thread. Will check them so I'm not being redundant.

rjpohl · « **Reply #59 on:** December 21, 2014, 04:38:15 AM »

Hopper does run away with 1 or more coins played.
Coins do contact roller and raise arm (I can raise the arm higher by hand and that's when it tilts, does not tilt when quarters activate roller arm)
Payboard does not step up

thanks for you help
Bob
