In Topic: Bgt Mini Wild Cherry Problems

Oh yes, still on pre-steel coinage unfortunately.. Anyone know how to retrofit a replacement mech for a Azkoyen L6 at all, or at an outside chance, know of someone able to update such a mech?

 

I'm going through this processs with mine now.

 

I have bought a newer X6 mech and am wiring it up to an Arduino microcontroller. I have this at a point where the new mech is acception coins and I can see which coin is inserted on my pc debug console.

 

The next step that I'll have a crack at this evening is sending the correct coin signals from the arduino to the machine, then it's all good. All I need to do (I think) is send a couple pulses down the correct coin signal lines whise monitoring the inhibit line. 

 

There is no direct mech replacement, __unlesss__ you can find someone who will program the coins to the correct pins. I tried euro coin, but missed the call from the engineer who was then on holiday so ended up with a regular X6 programmed mech.

 

On my wild cherry, the graphics say it accepts £2 coins, but none of the signal lines are for £2. I guess it's because I have a slightly older version of software in mine? 1.9 or something (I need to check). I am planning on pulsing the 50p line 4 times to simulate a £2 coin via 50p's being put into it. I can't do the £1 line as it would end up with the wrong hopper count.

 

It would be nice to connect a note reader up to the serial port on the arduino, but I have no idea what not readers are easy to interface to. Quite a number of years ago when I worked for Cromptons I wrote quite a bit of code that interfaced to CCtalk mechs and hoppers. Note readers weren't a things for us back in 2005!

 

I did have a crazy idea about making a board that intercepts the mech, display and hopper, then in theory I could halve the value of the coin in and payouts to increase the jackpot of the machine. That would me a heafty amount of work though then the graphics would beed upading too. I don't have the time for that at the moment. I would prefer to do that on something like a Las Vegas Six, £1 play £50 jackpot.

 

In summary: [X6 -> Arduuino -> BGT]


In Topic: Azkoyen L6 info (Mech for BGT mini wild cherry)

17 April 2023 - 03:28 PM

Just for reference on this issue, in case anyone else wan'ts to replace the mech in a BGT Mini machine.

 

I got hold of a data analyser and connected it up over the weekend and run some coins through the old mech.

 

The results of this are here: https://drive.google...Ems-dDq-E/view (I couldn't work out how to upload the image, perhaps someone else could do that?)

 

Theory of how the L6 Mech works:

 

There are 3 (perhaps 4) output channels from the mech and the inhibit input signal. On this mech it's pins 3,4,5.

 

The Inhibit signal (pin 6) is usually held high.

 

Once a coin is inserted the machine pulls a signal is sent to the machine on 1 or more pins (different from the usual mech). For eaxample 5p is sent on pin 3 only, whilst 10p is pins 3+4. It uses multiple channels per coin! This seems to be a thing with Azkoyen mechs as I have gotten hold of an X6 mech which is similar, but different channels!

 

In response to the validator sending the machine a coin signal on 1 or more of the pins, the mech pulls the inhibit signal low, this is to tell the mech to accept the coin. 

 

The mech now sends a longer pulse on 1 or more pins to tell the machine that the coin was accepted correctly.

 

1, Mech validates coin and sends a low singal on 1 or more pins

2, Machine responds on the inhibit pin (6)

3, Mech accepts gate opens and a longer pulse is sent to credit the machine.

 

So, where does this leave me?

 

I have to rig up an Arduino with a ULN2803A to interface between the newer X6 (or any mech) and the machine.

 

I'll post back when I make some progress. Due to the differing coin channels it's not possible to rewire the X6 or another mech to interface to the Wild Cherry.

 

Hope this info helps someone else.

Your post is a bit confusing, but I think, you appear to be talking about 3 machines.

 

You say about JPM Fright Night. The only machine I can see called Fright Night is by Empire, unless you mean Fight Night, which is a Maygay machine, based around Boxing.

 

Then you say about a Pinball themed JPM machine, special flipper button. I think it's the attached picture of that machine, but it's not emulated.

 

Then you show a flyer for Nite Club.

 

Nite Club, has a layout for it.

I had never seen one of those Pinball Wizard machines, is that by Ace?

Thanks, I pinched the wrong image from ebay :-)

 

I have only ever seen one in the flesh, so I guess the roms are missing and unlikely to be found?
