new brain for old coin op pachinko,

[The13bats]

In my collection i have 4 of the old coin op vintage pachinkos,
Basically they are modded to cyclical and you pay a quarter for balls the amount you get can vary,
You play for scoring and balls get enough points get a free game, tulips open with solenoids,

So one never worked, and i wouldnt know where to start in checking its antique brain board so some of you
Arduino savvy, is that an option and what type costs would be involved?

Thanks
cheers

i could be interested in 2 plug and play units as well.. (computer pachinko)

I can build a PC from scratch, but know nothing about Arduino possiblities, but from other antique
Arcade games i have i dont believe the answer is to waste time with the obsolete brains in my machine but otherwise
i find them great fun

I found a 3 part video on youtube the fellow has a machine like mine,
He confirmed my notion the brain in these is obsolete
I agree with him a person would have to be a wizard to trouble shoot the brain board but he found that guru
on here no less but i cant understand the name he gives and this was 2007.
My machine seems to have more mental problems or gremlins as he called them,

Mine will power up, the light that is normally empty hopper stays on
the score is on 000 and scoring light never lights the credits are at 1 and do not change
if a ball scores the solenoid that kicks the seesaw back will work but the solenoid that opens tulips and the other that pays you the balls do not work,
The coin mech will make an electric counter inside machine move but does give credits it stays on 1
i can only find one switch and when its triggered it resets the seesaw but at that same time balls should be paid that jackpot solenoid is on a different circuit and as i said doesnt work
The wiring appears intact so i guess everything is controlled by one swich,
The "tilt" works but requires machine to be unplugged to reset,
I have no idea what the green wire that just end goes to and the big bell did ring a few moments stopped and never rang again
im not hopeful my brain can be saved, lots of ic and other things that could be bad,
I have 3 others like it thsy do work i meed to drag one out to compare

I have done a little with the arduino. I'm currently making some boards for my model railway. For a beginner it can look to get complex really quick.
On top of that. it only has low voltage, low current outputs, So anything you drive will need a breakout board or other to work. There are plenty of premade plug in relay boards and tutorial videos.

A good starting point is to list all your inputs (sensors, coin acceptor etc) and outputs. (Ball release, solenoids. displays etc.)

This is the little board for my signals for the railway. I'm sure some one with a lot more experience could have made it smaller. especially as all my componenets are mounted on one side of the board only.
Along the top are 6 sensor inputs each with their own power supply, After workign on doors for many years I always found it annoying there naver gave enough voltage outputs for sensors.
The bottom row is signal outputs for 7 leds.
Most of the stuff on the right is power supply. AC/DC input, fuse and 5v regulator. Then an arduino nano mounts in the middle.

Thanks clam,
As i have been saying i know very little about arduino but know it would work, heck my phone is light years ahead of the brain in my pachinko.
I have several hobbies they would come in handy for example i go nuts at halloween and many people use arduino to control spooky stuff,
I also collect other old arcade machines, i like cranes, i have old crank diggers a late 70s that is just push button relay i have a 90s candy crane that the brains went out no replacements
so one fellow on that forum talked of making a plug in ready to go arduino type conversion i would have bought one as would others but he never came back,
In the case of my pachinko my guess is some way that one switch controlled jackpot, seesaw reset and tulip open
Then there is the money paid switch, credit switch tilt, points led and credits led,
I had a electronics guru buddy that just vanished several years back, he would have either made my old brain work or cobbled together one that would,
I wasnt really expecting that a plug and play was out there in this world for my coin op machine, they were not all that rare but just uncommon now days i love the vintage machines
But i find the way the coin op modifications keep score yet still pay out balls makes them far more fun to me like arrangeball or my baseball machine
perhaps an electronics guru will see this thread take mercy and for a fee of course help me out,

As far as low output volts/amps couldnt those low outputs be used to trigger relays with whatever volts from then one desires?

[Drunkenclam]

Correct. You can use a relay to fire high current/power devices. But you can't just connect a relay coil to the arduino outputs. But there are plenty of premade relay boards with one or more relays on them. With all the components fitted. The one in the link below seems to use mosfet instead of relays.

Well last night i dug 2 of 4 out of storage, while converted by the same outfit its a bit different in function,
I have no idea why but they made it less fun to play,you pay your coin and it dumps 3 sets of 14 balls
you play for score only event though it has a replay led and credit button they are moot
it dumps the play balls when you drop a coin and if you drop a 2nd coin it doesnt rack a credit it just tries to dump 42 more balls,
Problem with that is the way they modified the scoring ball seesaw it doesnt return that ball to player like machine 1 of 4
it places the ball in the rear ball tray and if you place too many balls in that tray it will jam when you score too much,
And scoring is 10 points each pocket hit on the led counter, no extra balls paid like on 1 of 4,
And no free replay, even the same how to play marque decal thats on 1 of 4 is modded with a piece of tape
to hide where it read a score of 100 give free game, also both use the same brain board but 2 of 4 has mods to it too,
I fully believe comparing the rwo that the modification were from the company converting these but
why cheat players out of a free game, pretty much no incentive to keep dropping quarters as 42 balls play out pretty quickly,

As far as 1 of 4 im still hopeful that i can find an electronics wizard who wants to try to get it working at a fee i can afford
i removed the board and mapped the wires,

i had an arrangeball that i paid a guy to convert to a PIC microcontroller and he did a fantastic job but was very expensive. however, this particular machine had a lot more rules than a coin-op pachinko. regarding not allowing players to win a free game, that's not surprisingas i've seen a fair amount of arrangeballs with with bonus features disabled and/or pins bent to make it impossible to achieve certain objectives.

[The13bats]

I love my arrange balls, both ladt i tried work well but yeah i would be willing to pay more to get one with brain damage working
When you say expensive im noisy what ballpark?
I would assume arangeball mods were done in japan,

My coin ops are different to me, they are modded in the USA and in this case remodded, i dont recall 3 and 4 of the coin ops i have function they are in storage, one is extra molested its playfield all reworked to look like vegas casino,
Coin ops are more fun to me in a way than most vintage machines although i do enjoy my baseball that takes tokens and wild sub hunter machine,
Doing a brain transplant on a coin op is pretty simple compared to arrangeball nut arrangeball is worth it,

[emmadog]

i'd give you the exact figure if i could remember as it was over a decade ago it but it was over 1k. it was a lot of work from having to draw out the schematics to assembling all new hardware (lots of solenoids on this particular machine), etc. it was also a late model arrangeball so it was about as complex as they got (before manufacturers quit making them) which contributed to the cost of the microcontroller. the guy that did the work was an electrical engineer and did some other work for me such as developing LEDs for number grid on arrangeball machines. i was tired of dealing with those pain in the ass grain of wheat bulbs. concerning modding, all the machines i've received that were modded were done so by the parlor. the mods just wouldn't have made sense if the machine was used in a home setting.
