Sorry I just realized that I forgot to count two symbols on the right wheel, the 2.Q3

you're doing good.

if you want to make it like bally did it so you'd match bally documentation, below is an example of a reel wiper wiring diagram used on the 742A-118, 742A-2G and a few other models.  They are oddball machines with operator adjustable payback percentage.

1] the columns of rivets marked 1-9 are the slot depths, where 9 is the deepest slot.  The gotcha ...

2] the diagram is drawn looking at the wiring side, so the wiper arm represented by the dashed line can only move left.  It's impossible for the wiper contacts to sit on the rightmost 4 columns of rivets on the diagram.

3] the way the wiper fingers are connected together is indicated by the sets of joined arrows to the right of the rivet columns.  You'd want to redraw those like your game has.

4] the tape symbols corresponding to the slot depths are above the rivet columns.  It's not always true that each symbol maps to only one column depth.  On multiple line games, games with mystery pays, or games with scatter pays, a payline symbol may index into different slot depths depending on what symbol was above/below it on the tape. 

so the J-M rivet columns in your picture are not used, and columns I-A are slot depths 1-9.  In this case, you don't use depth 9 either.

you could load the diagram into a graphics program and erase the existing information to create a blank template, then fill in the wiring of your game.  For the wire ids, you can look at the payout counter diagram and use those ... bally tended to use the same id's for the payouts (e.g. the wire on the 2 trace is 13, the 5 trace is 15, etc).  If the same color wire was used between reels ... but is not the same wire connecting to multiple reels ... then the second use of the wire color would be something like 13-1)

742A afaik have the connections to the payout counter coming from the reel 1 wiper board, so some of the wires on the reel 1 board are going thru the plug connections to your m-645-96 board.

recreating the reel wiper wiring diagram is a bit of work, but it's the only way to determine how the game paid and how much it paid when you don't have all the paperwork or the glass ... or if it's a custom machine or just something assembled from random parts.

having said all that, if the goal is to make a working machine with bally original glass (rather than producing a custom glass), then you're probably starting with finding a glass to stick in the game that matches pays your payout counter disc supports (or replace the payout counter disc also), then you rewire the reels and make tapes so the index discs you have will produce what the glass says.

you may wind up using multiple slot depths for the same symbol to adjust the payback percentage or hit frequency, or you can do the mystery pay approach where the game makes a payout that is not on the glass

finally, if you want to figure out how the 742A-2G machine and it's variable payback worked, I think I have the schematic and some other docs for it ... but not the payout counter diagram.

Hello, here is the statement of the cards but I admit that it does not necessarily speak to me...

[wolftalk]

great!  I'll convert that info to a schematic representation and it'll be easier to see what the pays are once all the mistakes I'm going to make are fixed :-)

it'll take a few days tho ... have a few other projects to deal with first.

it looks like your reel wipers/boards are from a 742A-29E - see attached w-1041-320-322 diagram.  The matching reel index discs are P-484-[254, 255, 256] also attached.
 
so you have parts of a 742A-29E, 742A-114 and unknown index disc that could be either or something different.

the payout counter disc is the same for a 742A-29E and 742A-114, but the wiring may have been slightly different - depends on the payouts for each machine.

unfortunately, that means the reel wiper wiring can't be used to figure out what a "two for the money" machine was, so that will stay a mystery for now.

you can compare the below index disc definitions to what you have using your notes and the 742A-114 docs posted previously.

besides the glass, the hard part is usually the index discs.  You can rewire the wiper boards to match the index discs, but in this case we don't have the documentation to figure out the original payouts of a 742A-114 (the basic stuff like cherry's and 3 of a kind you can assume ... it's scatter pays, wild symbols or whatever "two for the money" meant we don't know).

you may need to find a glass, then wire the reel index boards and make reel tapes to match the payouts.  You'd have to decide which slot depths mapped to which symbols, and you could map more than one slot depth to the same symbol if you had more slots depths than symbols.

if you could make index discs, then you could make the machine any 742A model you wanted ... assuming you could make/find a glass/reel tapes and the documentation existed.

you could also make a completely custom game with any payback percentage you wanted if you can make a glass and tapes.  Design a 200% payback machine and I'd still manage to lose all my money in it :-)

Good morning,

Thank you for your time, your advice and your precious help, I will listen to you and redo a 742 machine with cherries and pears because I have a window and I will just have to redo the strips and for that I am currently missing the drawing pears so if someone has this in high definition I'm interested.
I also have to fill two slots on my disks and I will have a machine that will pay around 76%.

Have a nice day
Philip
