Coin Door Issue... Need help / Advice

[Comp1demon]

I have a Happs 4 slot coin door.  I am building a quad cabinet so this is the door I need.  I have it all wired up and working properly with a IPAC and the Light harness works fine.  I tried a 2 player game and 4 player game and all regester credits properly.

Here is my issue.

Every Coin Falls right through to the Box.  If a Credit Don't register or I drop a coin in slots 3 or 4 on a 2 player game the coin falls right through to the cash box.  How do I get it so the option for the reject button works?  IS there a way to keep the coin in the Chute or something so the reject button can return the coin? Is thisx possible on a home brew cabinet?

Thanks,

Sounds like it's doing exactly as it's designed; collect money into a bin.

You want your money out, you open the coin door and remove the bin.

If you just want the money to come right out, you shouldn't be using a coin door!

If the coin sticks in the Chute, it normally will not register a credit (doesn't trip the "switch" until right before it falls into the cashbox).it was designed this way to minimize theft.  What you may want to look into is using tokens (if you concerned about having money in the coin box), or wire up an extra button to the credit switch (on the coin door, or the encoder), so that you can get credits by either inserting a quarter/token, or pushing the "credit" button.

I agree with Peale...what you have sounds like normal operation, and if that is not what you are looking for, ditch or mod the coin door.

Good Luck!

is it not registering a credit when the machine keeps the quarter in players three and four...?

[2PacMan]

I think what he's saying is that sometimes the quarter goes in the slot and doesn't register a credit and instead of going in the coin return slot, it goes in the coin box anyway.  He is thinking that if it doesn't register a play, it should go into the coin return chute instead of the coin box. 

IF that is what he means, unfortunately there's no way to do that....like the above poster said, the coin return shoot is if the coin gets stuck in the mech.  My suggestion is that the mech needs adjusting if it is only tripping the switch sometimes.

It sounds to me like you want lockout coils.  These are electromagnetic devices which, when properly installed and given voltage, will allow coins to pass normally through your coin door and into the box.  When no voltage is applied, as I understand it, coins will all fall through to the reject bin.  That way when your cabinet is off, or not at a point in software where it can accept coins, it won't.  That would at least take care of some of the issues you're facing - though the problem of a credit not registering is not something I can answer without knowing why it doesn't register.

As for the four-player thing, though - the most sensible thing is to configure it such that all the coin slots are used in any game.  For one-player games you'd want the player to be able to use any of the four slots.  For two-player games you'd want the two slots on the left to work for player 1, and the other two for player 2, and so on.  In Mame that's likely something you could accomplish by editing the control configs for each game.

he's totally talking about lockout coils, cause i've thought of this before too, but it just seems like too much work for so little.

Sounds a lot like a bad Mech to me.  It accepts every coin.  Sometimes the coin is not lining up to trigger a credit.  Mech might be out of alignment or it is bad.

No the coin mechs work fine.  They regester a credit every time acoin is dropped in player 1 and 2 slots.  FOr 2 player or even 1 player only games.  slots 3 and 4 are wired up for Coin 3 and and Coin 4 and they work fine too for games like gauntlet and turtles.  Becasue they are configured to Keys 7 and 8 in mame.  On 2 player games Slots 7 and 8 do not regester credits at all becuase MAme still presses button 7 or 8 when a coin is droppped but the game getting emulated does not regester a credit becuase it don't understand the key press.    I was just curious if there was a way to prevent the coin from falling all the way through since 2 games wont regester a credit for players 3 and 4 (probibly not).

BUt the second part is correct,  When the Machine is off and there is no power the coin still falls straight through.  How can I make it fall right into the coin return area when power is off?  AS I remember some machines when off you had to press the coin return button to get your coin back when the machine was off (no power) some just went from drop to coin return with no button press.  Either way just was curious what my options are.

MY mech works fine, I wasn't implining there was a problem, just not versed on the mechanics of coin doors very well, just asking what my options are here.

I don't think you can do much about the coins dropping through with the power off, or with the player 3 & 4 on 2 player games.  Not without more advanced equipment would be my guess.  The only solution that I can think MAY work, would be to go into the configuration of the 2 player games, and see if you can set them up to also register keys 7 & 8 as coins drops for player 1 & 2.  You would basically have 2 coins slots working for each player.  I'm not sure if it can even be done, but I'm sure someone will correct me if it can't be done.

With power off, there's no solution. Basically, if someone was dumb enough to drop a quarter into a machine that's turned off, too bad for them.

But with power on, there is a solution. Some coin mechs come with an electro magnet that when activated will catch the coin. But I don't know much more about this, and I really don't think MAME could control them anyways.

Yes, that's the lockout coil I was referring to.  And when there's no power being fed to it (like when the machine is off) the coin will be rejected, so the player dumb enough to feed a coin into a dead machine still gets his money back.

Does my Coin Door have a lockout coil?  IF not how and where can I get one.  I just want to make my project as authentic as possible. 

AS for remapping games to regester button pushes 7 and 8 - thats a great idea - though it requires alot of work - but i will get there eventually.

[BASSOFeeSH]

Like what was said earlier, you'll just have to adjust your MAME config.

Since there's more games that DON'T have more than two players, simply setup the two left chutes(1 & 3?) to both act as coin 1 & the right two to act as coin 2.  THEN go to any 3 or 4 player games & undo it so that each slot only works for the specified player.

OH! So it works opposite of what I was thinking. Ok, that makes alot more sense than my dumb thinking.

So he needs lock-out coils that he could activate for certain games.
How about this cheaper method: masking tape on the slots.

ah, the simplicity of my two player cabinet...

This is the point at which my knowledge fails and  I'd need to do a search to try to find the answer for you. 

I think the determining factor is the coin mech itself.  Either it will support lockout coils or not.  Happ sells the coils but they're buried somewhere on their site.  I think they also sell a coin mech that specifically says it supports lockout coils, but it, too, is not where I'd expect it ("coin doors/coin mechs")

I am interested in having lockout coils on my cab as well but I think it'll have to wait.

[Comp1demon]

I found them on HApp but unsure if they are compatable with my coin door.  Email them to find out. 

How would you suggest you wire the coin doo so that all 4 work with 2 player games but the proper Player 3 and 4 are the only ones to regester when in a 4 player game and the coin is dropped into the proper slot.  I've been thinking about this and I cannot get my brain around how to make this work.


I understand the configuration in mame but how would the physical wiring be done and how would it not regester a P1 or P2 coin at the same time as P3 and P4 on 4 player games.
