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....

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 .

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.

Chief!
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

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!
Ciao,

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?.

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

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.
