Hello
I have a Mills Model M that has a hopper . The hopper does not work yet . The electronic side of the machine is set pay only one payout and that would be the jackpot payout . The total payout on jackpot is $8 . The mech drops 20 coins so this would leave the hoppers work to displace $7 in nickels.This is a nickel machine .The machine has an activator switch on the jackpot vertical finger payout .
If I manually push the switch on the payout finger I can hear a click coming either from the black box counter or directly next to the black box behind the sheet metal , also if I hold this same switch in it's closed (pay) circuit and manually push the counter switch on the hopper the counter on the black box increases .In one of the pics you will see a pin connector that looks similar to one of those old radio tube pin connectors it has 4 wires on it . I am sure something plugs into this , but what might that be ?
I am not much of the electronics guy but am capable of running a few tests on circuits etc . I am brand new to your forum . found it via some posts from here about the Mills Model M . Hoping someone may be able to help me bring this one back to life .
I am a collector and restorer of mostly mechanical slot machines and trade stimulators . I also have restored a 1932 Buckley Deluxe digger and other antique arcade games from the 40's .

Welcome to the Forum Sam, I am sure someone here can help you or maybe they have a picture of the area where that "vacuum tube" socket is that will show what is plugged into that location!
Anyone out there who is familiar with the Mills Model M slot machine with the addition of the hopper that can help the new member!
Bona Fortuna Sam!

Thanks for the welcome aboard :cool_thumb_up:
I hope someone on this board is familiar with some of these early casino attempts at keeping up with the Bally company . A really cool machine and deserves it's place of significance in slot machine history .

Sam,
A fellow I have been communicating with outside the forum about your slot machine is on this thread here below
1962 Mills Open Front (http://newlifegames.com/nlg/index.php?topic=10276.msg55418#msg55418)
possibly we can all communicate and get more information on your Mills M-Head!
Ciao,

Greetings:
I'm the one Monti was in contact with. I'm pretty sure that your machine was modified "in-house" by The Golden Nugget or by an outside firm other than Mills. The reason is that all the M-Heads with hoppers that came from Mills had the set up that looks like the picture at the end of this post. As has been noted by others, the parts Mills used (as well as other "re-workers") were off the shelf commercial parts and electronics. None of the M-Heads I've seen have the down-facing plug that looks like a vacuum tube would be used there. I'm not really an expert on the electrics by any means, but maybe someone here has seen this type of set-up you have before and knows what's up. Great machine you have there and hope you can decipher what goes into the plug socket!

That makes sense as Mills more than likely would design a circuit all housed in one box like the one you show so if an issue occurred in the field with something within the enclosed circuit the entire box/assembly would be removed and replaced very much like IGT and others now just replace mother boards rather than repair in the field!
Unfortunately it is folks like us in the hobby that usually try to repair the boards rather than try to find new ones which because of proprietary issues can not be obtained from IGT or others!
But it is a learning experience then, right? :Scratch-Head: :Scratch-Head: :Scratch-Head:
But a schematic or wiring diagram would be nice, something with test values for testing voltage present on the circuit!
But maybe that would be too much to ask for? :duh: :duh: :duh:

Hello and thanks for the reply . I am adding 3 more pictures of the interior of the cabinet . I believe it is very similar to your photo . just the counter and the sheet metal box are arranged in a different configuration .Hopefully you are correct in your assumption that these were put together with off the shelf parts . If that is the case there may still be some of these parts "lying around " somewhere . Finding them will be another matter !

Sam, the main difference I see here is that in the picture provided above of which I have made notations on, the Mills Bell-O- Matic factory installed hopper counter assembly is completely self contained for easy in field replacement if any part of the enclosed circuit fails during in house usage rather than testing and repairing on site where as yours is wired using exposed wiring, terminal blocks, Etc. which looks like an after market upgrade of the original Mills M-Head that did not have the hopper payout function so unfortunately yours will probably require a lot of tracing of the circuit with a test meter to establish proper current flow for correct operation, excluding of course what ever was plugged into the socket that resembles a "vacuum tube" type socket which is missing on yours.
Anyone else out there have any thoughts on how Sam should proceed to get this hopper counter system working correctly?

After some diligent looking, I'm revising my opinion based on the case serial number tag in your machine. Your machine is 2,123 completed machines ahead of the picture I posted of the top part of mine. Please see another of my posts from yesterday (6/11/2016) about how to get a close clue on the year of manufacture. (look under your mech and see if there is a felt pen marking with a date, then check the leading edge of the hopper for a date code followed by a serial number of the hopper. The other post is the best way I've determined to date an M-Head.)
Another clue is the "5cent" marking on the box: it's the same handwriting on my hopper and other parts of my M-Heads, meaning I think your machine is pretty certainly an as-built Mills Bell-O-Matic issued machine assembled by the same tech WITH AN EARLIER VERSION OF THE HOPPER CONTROL UNIT. I'd beat "Cool water sandwich on a Sunday Go-to-Meetin' bun" that your machine is around 1967. Check out my other post on another thread and let us know what you find on the front bottom edge of the hopper and under the mech.
Now, that still leaves the question of what the heck goes into that mystery socket!

Well, I believe another piece of the puzzle has fallen into place thanks to Sam's detective work.
Although I was off by a FEW months, we now know that the mech in Sam's case was made on February 22, 1968. His mech serial number is 2,963 mechs earlier than my 5-cent M-Head mech and his case serial number is 2,123 cases earlier than mine. Since mech number are unrelated to the case number as I pointed out in another post, we can deduce that there is a close time relation ship between the mechs and cases on both our machines.
Given that assumption (Sam's machine is a casino machine and mechs were swapped around a lot as casinos bought extra mechs and hoppers so that no machines on the floor would be non-working, and thus non-revenue generating.) It can fairly be stated that Sam's machine is an earlier generation of the M-Head hopper equipped machine. This can be deduced from the fact that all the electric equipment was placed in an easily removable box on my machine, whereas its a little less refined and less easily removable on Sam's machine. (See Monti's earlier picture and caption as he points this out rather well.)
Between Sam's machine and mine, Mills must have gotten word from casinos that it was a pain to yank out the upper electrics for servicing (cases stayed on the casino floor in place and did not go into the Slot Shop as a unit as they were screwed to their bases), and they developed the version that mine and later machines have, which is much easier to remove and replace by a slot mechanic on the casino floor. Mills also did away with the need to manually disconnect the mech from the electrics of the case via that large multi-pin connector shown on the left in Sam's empty case. On later machines, the plug is a long multi-pin strip plug mounted to the rear of the mech that plugs itself into a mating plug mounted on the inside back wall of the case when the mech is slid into the case (See photo below). Both upgrades are clear improvements and show that Mills was still making investments in product-improvement even though they were fighting what would turn out to be a losing battle against Bally.
Over the weekend, I'll pull out the top box on mine and compare the components to Sam's pictures and see what's either different or missing between the two. I'm am FAR from an electrical authority by ANY stretch of the imagination, but if we can figure out what's different, it may provide a clue as to what that socket is for on Sam's machine. In any event, I'd suggest that if anyone can ID the type of plug socket on Sam's machine, it may be possible to rule out that it's for a vacuum tube if no vacuum tubes were ever made that fit that socket. Just a suggestion of process of elimination.
Thanks again Sam! I'm compiling a list of known M-Heads as a result of this as I do not believe such a comparison has been done before as I truly feel these machines have been overlooked by the vast majority of slot collectors (NO disrespect intended) simply because they don't look like the earlier more collectable machines and/or appear to "scary" due to the weird appearing electrics.
Respectfully submitted,
-Caesar

Very well stated Caesar and very descriptive! :applause:
I agree a vacuum tube would not have been used in this circuitry but for some reason that type of socket was used to connect the four wires attached to the female portion of the socket, per Sam's information, to a possible circuit board for other controlling factors in the overall circuitry which was, as Caesar stated during an R & D portion of Mills improving of the slot machine for better servicing in a casino environment!
Again, Great description Caesar and I will be looking forward to your forthcoming research on the slot machine as I know Sam will as well.
Thanks for your effort! :hail: :hail: :hail:
Anyone else out there with information on this will be greatly appreciated also!

First off let me say thank you to Monti and Ceaser for all the time you both are dedicating to this topic .
Ceaser also look forward to your research and if there is anything I can do to help with the comparison of the electrics between the 2 cabinets please let me know . I wish I had a decent backround in electronics but unfortunately I lack in that .
Ceaser I agree whole heartedlh wih your last paragraph from your last post
this thread has had little attention from others . It is an ongoing topic in this forum as well as one other forum. This must be due to the fact that the model M falls into that in between category of mechanical , electro-mechanical phase of gaming machines , making more of a Frankestein type machine pieced together with whatever was available . I still think it deserves more attention if for nothing else it's historical value as a collectible machine .
Thank you both again for your time and hopefully we can solve this topic .

Thanks for your recognition Sam, but I and probably Caesar as well have inquisitive minds that are always trying to seek out more information and understanding of things that peak our interest as the timing of this particular slot machine by Mills Bell-O-Matic coming into play has stirred up.
Personally I think the lack of documentation is due to the fact that this particular slot machine came into being due to the need for other slot machine companies to keep up with the very impressive introduction of the first Bally slot machines and as such being a slot machine which must have been in the Research and Development stage probably in its entire production period and the schematics/wiring diagrams were probably "work bench copies" always under change and improvement in the shop with different scribbling by the bench techs as to changes incurred during the process!
I am not sure but probably Caesar can clarify that this particular slot machine was also short lived and was not used for long as well also explaining the lack of documention!
I am still hoping that someone with more knowledge on this machine will see this thread and chime in but if not Sam we have definitely given it a real try, right? LOL :banghead: :banghead: :banghead:

Greetings:
Here's the pics of the "innards" of the upper box on my M-Head below.
After some more studying of Sam's pic's, and comparing them to what's there and NOT there, I think that socket is in fact for a tube. Vacuum tubes (as I've come to learn) do a lot of things, including acting as a switch, diode and amplifier. My machine has a lot more solid-state circuitry in the box on that perforated board. Sam's machine lacks this.
It looks like the cord coming from the hopper terminates at the horizontal buss bar with a purple, yellow, red and black set of wires. They then jump the buss board and with the same colors go up and toward that plug. Two of those wires are the hopper motor power source (120VAC) and the others are the messenger wires for the coin activated switch that counts the coins as they are paid out. If Sam can trace the colors of the wires attached to the plug to that buss bar and to wherever else they lead, it's strong evidence that a tube in that socket was the predecessor of the circuit board in my later version. Just a guess, but I did some self-education on vacuum tubes over the week end and there are non-glass, metal case tubes that were made back in the late 60's. So that's my thinking at this point, but I'd venture a good guess that there is a tube that goes in there and functions as a switch. Next step: determining what voltage runs through it.
Once we know where the wires come from and go to that are attached to the socket, we'll be closer.
-
Boy, that circuit board looks like the old Heath Kit circuit boards of the 50's/60's, no traces on the board and everything hard wired, today that is all done with a couple IC chips! LOL
Maybe a cap or a resister here and there!
Thanks again Caesar!
-
And just some more info: Sam's machine MAY be the 1,436th M-Head made. I pulled my original Mills M-Head manual (It only covers the case and mech and has no info on hopper models unfortunately) and the photo below shows the mech in the manual having a serial number of 615758. Mills was using the old Dymo tape machines to serialize their mechs at one point (my steel case Compact model has this same numbering system and tape from 1962). Sam's is 617194 (as pasted in the case), so the math seems to indicate his is a really early model.
The last two pics are of an original Mills advertising postcard for my collection. Enjoy!
-
Yes, I have that same M-Head manual but I loved the postcard!
Of course finding the right vacuum tube for that socket could be a challenge though!
-
They probably had one guy soldering up those on the phenolic perf boards all day!
As to the tube, I agree. BUT, if we know what sources goes into the plug and where and what comes out of it, there's a good chance it can be really narrowed down and possibly identified based on what it does (switch, diode, amplifier of voltage).
One question for Sam when he gets a chance: I can't tell from the picture of the open cabinet front, but there is a black square in the way back of the bottom hopper portion of the cabinet on the upper left side. It might be nothing, but I want to rule out that it's a transformer/voltage converter so that we know the hopper runs on 120VAC. Jeeze, the more you LOOK, the more you SEE! Thanks, Sam, for whenever you can clear this next little issue up.
(Re the postcard: I found that on eBay years ago. Now I'd REALLY hate to see the insides of those progressive machines to see how they made THAT work! I'm actually going to measure up my pair and have a cabinet guy out here cook-up a pair for me. Nice place to set a drink while playing!)
-
Is this what you are talking about which is not clear in the other photos?
It is a multi-pin connector with I believe only four connections, two for the counting switch on the hopper and two for power is my guess, judging from the wiring I would think the hopper motor runs off of the dc voltage off of the drop down transformer but I might be wrong because a lot of the earlier EM machines had ac in various locations until the slot mechanics or floormen on the casino floor got tired of getting zapped and complained! LOL :Crazy:
And I agree, I am happy we are not trying to figure out how the progressives work on those puppies! :banghead:
-
Gentlemen
Sorry for any inconvenience . Been busy around here may have some time later today to research some wiring on machine . Bear with me always a lot of things on that "to do list "
May be a few days, before I have time to look but who knows !
And yes the postcard is awesome !
And the other pics to.

No worries Sam; I seem to have to have that exact same list myself! Thanks for the update pic. Have you ever tested the hopper itself out of the case? See my post to the other thread you started for a simple way to see if it works and the simple device you can make to check it out. If it works, that's one more issue to scratch off the list. From your prior post, I can tell the coin counting micro-switch works as it indexes up the Durant counters up-top. They should re-sent with the next coin played, but it appears that's not happening. Next time you have time, please post a pic of the left side of your mech (as you look at it from the front). Mine have a micro-switch mounted such that the reel-stop timing bar trips it each time the machine is played, and that (on mine anyway) resents the top counters if there was a hopper payout on the prior play. I'll await your update whenever you can get to it. Meanwhile, I'm going back to MY "to-do" list to try to make it into a "I did THIS" list!

Hello Caesar!
Thought I'd post this for Sam as he had sent this to me without the notations and it is easy for me to post it here!

Thanks for the post, Monti. The bottom roller-switch is like mine, but the one that is tripped by the first reel stop arm is a mystery. The both are activated on the "wind-up" portion of the mech cycle and are clearly separate circuits. Now the "why" part....
-Caesar
-
Yes, two micro switches do show redundancy as both switches show the beginning of the mech cycle however only the lower roller switch shows the end of the cycle as the one on the first reel stop would show the middle of the cycle but why would the electronic portion of the slot machine need to "see" the middle of the cycle unless maybe, and just maybe, the counter would reset mid cycle, which is strictly a guess on my part! :Scratch-Head: :Scratch-Head:

Monti & Ceaser and all who are watching this thread . I have done a little tracing on the 4 wires on the pin connector . white ,black ,red and yellow are the wire colors of the only 4 wires that are attached to this pin connector . The white and black wires go to a switch not sure what the switch is called it is pictured in this post it is actually 2 switches I believe .It is the first picture and these wires are attached at opposite sides . The red and yellow wires go to the bus duct shown in photo , the bus duct has been numbered by someone 1 on the right up to 14 on the left . The red wire from the 4 wire pin goes to the 11 spot on the bus duct from there it goes to the hopper . The yellow wire from the 4 wire pin connector goes to the 6 spot on the bus duct and from there goes to of all places the change girl switch .
I have not tested the hopper as yet but will be there soon hopefully .
-
A couple of more pics from inside the cabinet showing where most of the electronics are .

Thanks for posting more pics Sam, still a mystery here on my end what would plug into the vacuum tube socket but it would be interesting to put a VOM on that puppy and see where and what the voltages would tell us!

Fellow Members,
Great information posted so far. I believe the tube is a nine pin tube rectifier, that Mills installed.
It was essentially a tube diode, prior to the introduction of transistors.
I have a four reel M Head Machine With out a Hopper. I am going to look under the mechanism to see if
their is a Date Posted. As I understood all Mills sold out its name in 1963 to American Machine and Science for
a half million dollars. The last machine that carried the old Mills name ended in 1979 and sold their tooling to Ben Coleman from Sparks ,Nevada . He manufactured and sold parts to the growing home collector's as Ben's Coin Machine Service.

Thanks for touching on some of the Mills Slot Machine history!
Here is a link to those who may be further interested in the company which had many different names during it lifetime!
http://millsnovelty.com/?option=com_content&view=article&id=13&Itemid=86 (http://millsnovelty.com/?option=com_content&view=article&id=13&Itemid=86)
My days in the casino's of Northern Nevada where in the 60's/70's and I had not heard the name Ben Coleman and Ben's Coin Machine Service but will research it for my personal files on Northern Nevada Casino History!
If you have any more information on Ben or his company please send it along!

Monti,
Thanks for the update. I remember in Reno, NV. @ 777 Forgot street name . Their was a brick warehouse small in size on the corner.
Tony Mills was selling machines as collectors items, he had Rol-A-Tops at $7,500. and Mills High Tops for $3,500. A price that was greatly inflated even then for the times. Mills Parts he sure did have them, , though not cheap. He had nothing on old family history paperwork. He was a real fast moving fellow and he had to sell and move them to live. I recall he moved to Scottsdale, Arizona and passed away in Arizona and not Nevada as your sheet outlined. I sure enjoyed meeting him and he showed me what he had left to sell, I kind of think he was getting ready to go fairly soon to Arizona at the time. That would have been in the very late 70s or very early 1980s.
Monti, do you still work or deal in machines?.
Chief
-
Yes Chief I do!
As I am retired now I do it as a hobby as well as bringing in some extra change! LOL
I spend more time on the CoinOp forum as they deal more with the antique slot machines!
Been in the slot hobby since early 80's, picked up the skill working in the casino's as a slot mechanic among other jobs,
in those days you had to be versatile, if you know what I mean? LOL
Do you have history in Reno/Sparks area?
If so you probably knew Al Peccoli and the boys at Nevada Novelty, Lou Bennetti,Etc.
Ancient Slots out of Vegas did some selling in Northern Nevada as well!
I may be wrong but I believe they had a shop/store in the basement of the then MGM!
Absolutely loved their parts manual as it had a great breakdown of parts for slot machines!
Last time I spoke to Tom Krahl he told me had cases of those old parts manuals and after his passing Steve probably has all of them,
would be great collectors items!
Should have had Tom send me a few!

Yes Sir, Monti.
I recall two great shops with Slots, the one in Reno was on the second floor downtown. Do not remember any more the building they were in and one in Las Vegas in the Casino ?. They all look the same inside to me. No, I do not have any history in Reno, just knew fella's their. I recall when the M.G.M. opened with the Classic Machines and were the locals and tourists, not a bit happy playing them.
Do you know name of the book you mentioned. I recall ever seeing it & what machines did it cover?.
Have any thing you want to trade at present..

Hello sir and welcome to the thread , sounds like you may know a little about this machine . Monti and I as well as a few others have been trying to locate info on this unit . Most likely looks to be an end run Mills machine that was possibly updated with a hopper by possibly the casino .
The rectifier you refer to above are you aware of any that are available or a source of more info on this subject ?
Glad you have brought this post back to life .
Sam
Hello to you also Mr Monti !

Howdy,
Thanks for the welcome to the thread. The machine in question was by Mills. The casino's slot shop did not have the time or the average slot mechanic have the expertise needed to devise such a new add on. Mills would make a bunch of slots, put them out and pull them if they did not gain acceptance. Thou, they had a large bunch, that were just so-so, even though they took them back. A large bunch was sold overseas. They never had the expertise, to just put out a machine, nor did Jennings have one that could take on the giant Bally Company. Mills & Jennings lost because of their not being able to let go of the old payout fingers and slides for the smaller payouts.
I will look to see if I have some tube rectifiers. Even though Mills put in a Nine Pin Socket they may have only used Eight of the Pins and used a eight pin rectifier, one would have to check the tube socket bottom and count the wires attached to the socket.
Hope a bit of this information may have helped you:

Hello Chief
I will run to the garage later and take a look at the pin connector , but as I recall I think there were 4 wires coming of of it which struck me as unusual . Again though a bit later I will double check .
Thanks for the quick response
Sam
-
Possible if it has only 4 wires on a nine tube receptacle , a 4 pin rectifier, Then one wire would act as a fuse or complete other functions.

Sorry for the delayed reply .Easily side tracked on my end .
The round 9 pin connector only has 4 wires connected to it . Not sure how a tube would work in that connector .
That is all I have for now .

Howdy,
The pin tube socket holds a four pin tube, called a rectifier. It changes A.C. current to D.C. current.
D.C. current is what runs your Mills Hopper. I will look to see if I have a tube that will work for you. It is old
technology, even at that time your machine was designed and built.

They all look the same inside to me. No, I do not have any history in Reno, just knew fella's their. I recall when the M.G.M. opened with the Classic Machines and were the locals and tourists, not a bit happy playing them.
Do you know name of the book you mentioned. I recall ever seeing it & what machines did it cover?.
Have any thing you want to trade at present..

Chief!
Sorry I didn't get back to you sooner but I haven't been getting notices on replies here, spend more time on CoinOp as they deal more with the older antique slots which I specialize in!
Here is a picture of the parts catalog from 1990, it had parts for Jennings, Pace and Mills and cabinets and castings as well!

Sam,
You need a 12AU7A OR A 6EA8 TUBE.
I am pretty sure it's the 12AU7A TUBE YOU NEED.
I do not have any @ the moment. E-Bay should be able to take care of you or a antique radio tube for sale supplier. Good luck.

The 12AU7A is a great amplifier tube, also look up the tube on Wilkeup. It also makes a excellent Rectifier as well.
About 2/3 the way down the page.

Sam 2002,
I found a 12AU7A tube. You can have the tube for free, if you would pay the shipping. Hopefully the tube puts you in business.
