Credit Mod

Just stumbled across this on a Japanese site. Looks like it is a plug and play mod that will automatically add credits.

i know someone thats suppose to be going to japan and i was going to have him pick me up one or two, i found out about them last week and think they'd be cool to have and tryout

COMEON!!! WHAT THE HECK ARE YOU THINKING!! all it is: a button that is wired parallel to the coin counter that every time you push it it sends the same signal a coin would as it passes through the acceptor. want to add 10 coins push it 10 times want to add 50 coins push it 50 times. i wired my pulsar to do this with the cash out button as it's of no use for anything else to us! it just takes a little time to load the machine but saves on the opening/closing of the door!

**TANK** · 03-01-2005, 12:21 AM

i just reread it and it appears to eliminate the coin altogether, mine still pays out so you have to fill the hopper on occasion but what fun is it with out the coins hitting the tray?

**maury** · 03-01-2005, 12:23 AM

So is there a button (not like a button) but a think you can tap to fake a coin going threw? I know on Pinball machines if you just flick the wire it will register credits, Anything like this on Pachislo?

I had thought about doing just that on my max bet machines that had single bet buttons. But, after hearing others describe the way the coin acceptor worked, I assumed that you'd have to generate a double pulse to activate two sensors with a timing that was close to that of a coin rolling past the dual sensors.

If all it takes is a simple push button, I'd like to give this a try. How about a few details about what you did? What machine you did it on, the wires you connected to? Or anything else that you think might help me do this.

**alexilla** · 03-02-2005, 12:12 AM

Yes, I would be interested in trying this as well.

If my math is right, the 9,000 yen is about $90! My understanding is that this device replace both the need to input tokens and also output tokens. I may be wrong, but that is my understanding. This came up in a similar thread that I started a few months back.

You can get past the token in issue with PachisloUSA chip for less than $10. I built a cheap circuit (<$6) using a 555 timer IC and a few resistors that simulates the token payout piece, so for less than $20 you can do the same thing (with some soldering, of course).

**Lazarus** · 03-02-2005, 08:51 PM

TR. Can you give us more info on the tokenless pay out please.

Utopia1dc · 03-02-2005, 08:58 PM

I don't know, maybe it's just the purist in me, but why would you want any of these modificatins. I can understand the volume mods because these are loud and we have kids and spouses to consider. But to take away the coin in and coin out with mods just defeats the purpose of having a slot machine. By the time your done modifying, you could just play a video game on your ps/2 or xbox. Sorry for the rant. :oops:

Just my 2 tokens worth (or whatever mod your using)! :lol:

**RKnarr01** · 03-02-2005, 08:59 PM

utopia i totally agree i like to keep my machines totally stock i wont even put a volume control in

**logicprobe** · 03-02-2005, 10:24 PM

Well... everyone has an opinion.
I would think it's something that could be used WHEN you want to use it.
Eliminating the hopper payout noise could allow for playing the machine when the kiddies are in bed, or at night when you live in an apartment, etc. Besides... tokens cost money! Want to play with tokens? Put the hopper back in, and remove the mod!

TR, how about letting us know a bit more about this! There's two opto-interruptors in the hopper. How have you configured a 555 to handle the sim?

RK... no volume control??? DANG!!! You ARE a purist!!! Ever hear of tinnitus? If not, you will... or rather than HEAR of it, you'll read about it someday.

Utopia1dc · 03-02-2005, 10:33 PM

logicprobe-

I understand that not everyone would agree with my opinion. And you are correct, WE all have one! :-) It just seems with all this modifying, you could just play a video game of a slot machine. If you take the music/sound away, the tokens away, put in an automatic reel stop...is it still a Pachislo anymore? :-)

P.S I have not installed a volume mod either. All are ok in the low setting except Aladdin, that's a bit too loud. My Arra King is a little loud in the low setting, but tolerable.

**Urban Archaeologist** · 03-03-2005, 02:30 AM

I like to leave everything as original as possible too, but I do understand some folks need to quiet them down because of other family members, neighbors, etc.
Plus "possibly" another good reason to modify for not using tokens "could" make them acceptable in states that don't allow any type of slot machine. The modification would make it more like a arcade game.
Just my opinion which in the scheme of things means very little!!

Sorry for the delayed reply...been out of contact last few days. The 555 timer circuit that I built was one I found on the WEB at: www.doctronics.co.uk/555.htm It is an astable circuit that produces pulses. I built it a month or so ago, but I believe I used 3k and 1k ohm resistors for R1 and R2, and 47 uF for C. That gave me an 80% duty cycle (mostly on) with low pulses at a frequency of about 6 Hz. I got the supply voltage from hopper opto sensor (7V) and wired the timer circuit to be always running. I then used the 24V DC that triggers the hopper payout rotation to open a relay which connected the timer pulses thru a pull-down resistor to the normally high sensor line which, when pulled low, simulated token payout. I played around with the capacitor to get the frequency close (settled on 47 uF as noted above) and the pull-up resistor (I used a 100 ohm) to get the right voltage level to simulate the payout.

Of course, after getting this to work, it was getting late when I got sloppy and accidentally shorted the 24V DC to a lower voltage wire, took out the PachisloUSA chip and think I also did some other damage to the machine (old Yamasa)..reads E0 error code. I haven't had much time to get back to see what is wrong, but the timer circuit seemed to work fine simulating payout until I got sloppy.

One of the reasons for doing this was simply to see whether it could be done. The motivation was a question from a friend. The thinking was that a machine could be put on display in a public place and played for fun, without any concern about loss of tokens, appearance of gambling, etc. Of course, one could extend it to the issue of where the Pachislos are illegal, but I would guess the argument wouldn't hold much water, unless the machine was permanently configured to not accept or payout tokens.

**logicprobe** · 03-06-2005, 01:03 AM

TR...
Thanks for the response on that.

The hopper circuits that I've seen have two opto-interruptors in them... and their signals look to be timed mechanically as a token is ejected.

Did you use one of these for each sensor?

**spooner** · 03-06-2005, 01:17 AM

I would love to get hold of one of these bad boys and crack it open to find out how it works. I think it could be an easy and inexpensive feature to add to the clip on mod I am making for the PachisloUSA chip!

As far as the debate on to modify or not to modify, here is where I stand:

Whatever makes the machine more fun for you to play is what you should do That being said, I prefer non-invasive mods that do not permanently alter the machine so as to protect its original state as much as possible. The problem is that the original state of many machines is just un-playable (too loud).

I also sell machines locally when I get a chance, and I cannot count the times a customer has asked about bandit arms and autostop chips. They don't seem to care that adding these things will make the machine double in cost, and make it less original. They just want what they want!

Who am I to say no to such a request?

Finally, I like to play my machines in their original state (except volume) as much as possible, however, I also like to respect the desires of my friends and customers and let them play however they want. After all, it is just a game ... right!

Just my http://66.47.27.23:8998/img/twocents.gif which is all my opinion is really worth anyway! ~spooner

Utopia1dc · 03-06-2005, 10:39 AM

Just my which is all my opinion is really worth anyway! ~spooner

Oh, come on....it's worth at least 2 tokens worth! :lol: (Remember a token is worth more than a penny! :lol: )

But I agree with your above assesment. To each their own when it comes to mods...just some of them get expensive. You take a $150 Pachi, put an arm bandit, auto credit, L-pad, etc....and you turned it into a $300+ machine....could have bought a Dragon Dice or Speed Racer? Just food for thought.... :-)

**spooner** · 03-06-2005, 10:51 AM

Very true ... but remember, if you bought that Speed Racer, you would still have to put on that L-Pad, bandit arm, autostop, etc. which would make it at $450 machine! That is if you are into all of that business!

Where does it end? For $499 you can buy a full size silly Vegas machine! (although I honestly don't know why anyone would want one over a pachislo!).

Thanks for helping me remember that money doesn't grow on trees, Utopia1dc!
