Electromechanical Bally

[filounet]

Hello,

I have just bought a Bally slot of a size of a 742 but alas it does not have the glass, nor the bands on any of the 3 reels nor the identification plate.
There is no information inside the machine but just the metal rollers which are identified as B201, B202, B203.
Is it possible to know what are the models of bands but also the designs on the bands as well as the gains?
There may be a table or a file with its information for electromechanical as I have already seen for e-series machines
Thank you for your help

A couple of photos might help identify the machine.

See attachment with related numbers containing basic machine information.

Hopefully it will load in the horizontal direction.

the number stamped into the reel index disc are sometimes the number corresponding to the engineering drawing, other times it was game ID code.  The game ID codes are not in the spreadsheet I made that David posted, but you can find them in documents in https://bingo.cdyn.com/slots/bally_info/

I'm guessing your codes are B-2Q-[1-3].  They often left out the dashes.

if so, that'd make your game a 742A-114 - Bally "two for the money".  Unfortunately, I don't have a schematic or a reel wiper wiring diagram for that game and don't know what a "two for the money" is.  The only other one I have in the listing is a 742A-14A, tho my listing is not complete, so more may have been produced with model numbers higher than 742A-450

info I do have:
- reel tapes are m-220-[201-203]
- index discs are p-484-[314-316]
- payout counter - w-923-11

since the files are too big to post here, I put them in in https://bingo.cdyn.com/slots/742A-114/

without the reel wiper diagram or schematic, you'd need to reverse engineer the reels to figure out what made "two for the money" unique.  Often on the 742A machines high resolution pictures of the reel wipers and the wiring on the reel wiper boards is good enough to figure it out.  To get good pics of the reel wiper wiring requires unscrewing the mounting bracket from the reel mech frame so you can move the boards and see everything.  I usually unscrew reel 2 and 3 boards and flip them out of the way, then you can take a good pic of reel 1 wiring.  Then mount reel 2 board and take a pic of it, then reel 3 board.

if you want to email highest possible resolution pictures of as much of you game as you care to take to slotpics@cdyn.com, I'll add them to the folder with the above drawings.

Un grand merci à tous pour votre aide précieuse qui me permet de bien avancer, je vais regarder cela de plus prés

A big thank you to all for your precious help which allows me to progress well, I will take a closer look at this

[filounet]

Vous avez complétement raison pour les numéros sur les disques 2 et 3, par contre le disque 1 n'est pas celui d'origine.
Donc avec cette information il n'y a toujours qu'une seule machine possible?

You are absolutely right about the numbers on discs 2 and 3, however disc 1 is not the original one.
So with this information there is still only one possible machine?

Désolé je viens de regarder tous vos documents fort intéressant et j'ai bien vu qu'il y a deux machines différentes
Merci et bonne journée
Philip


Sorry I just looked at all your very interesting documents and I saw that there are two different machines
Thank you and good day
Philip

Hello,

I do not understand the logic between the M-220-71 strip which must correspond to the second roll, for the moment I have only managed to find this one for purchase and the toothed wheel B.2Q2
I do not see the correlation between the drawings and the depth of the notches
thank you for your explanations

[DavidLee]

As there is only one seven on each reel. Therefore there’s going to be ONE notch (index slot) cut into each reel disc that will be the same depth for the 7s. Most likely it will be the deepest cut slot.
After determining the one (7) slot on each reel, align the slot with the index arm.
Place the reel tape against the reel with the 7 in the center line position.
Mark the position, insert tapes in the right order 1-2-3.
Lightly crimp reel edges in one or two areas allowing for minor adjustments.
Finish crimping when all symbols align well with the center line.

Regarding the tapes, check eBay as there might be some re-manufactured tapes for that machine.

Sorry but I have a problem of understanding, the locations at the level of the combs which are alone are: 2, 5, 6.7 and 8 and the drawings alone on this strip M-220-71 are an orange, a plum, TAC and 7 so it does not seem logical to me or it is that the machine is not a Tictactoe but another model with different bands such as the M-220-202 band for example in the file.

Your machine is wonderful 

[DavidLee]

Thank you.
Can you take photos of the machine interior as to view the components in place.
Also the exterior might help.

below is the complete index disc diagram.

at the top of the columns are "slot numbers" ... those are the same as the symbol positions ("Division numbers") on the reel tape definition document.

i'm not sure why you are looking at a reel tape for a tic-tac-toe machine (code S-TTT-x), so I'm going to stick with the B.2Q2 tape which is M-220-202 and use the 7 as an example.

per the M-220-202 definition, the only 7 is at tape division 10.  That corresponds to index disc slot 10.

per the index disc diagram, slot 10 for disc p-484-315 is depth 8.

the depths are the measurement from the center of the disc to the bottom of the slot (R/radius), so depth 1 at radius 2.719 means the slot is very shallow.  Depth 8 is 1.734, so david is right and the 7 on this game is the deepest slot on the index disc.

knowing that, you can do as david suggests and position the tape so the 7 is on the payline when the reel is indexed in the deepest slot. 

afaik, the factory did it using the slot corresponding to the reference hole in the disc since the highest paying symbol is not always the deepest slot on the index disc.  See the first three pics in https://bingo.cdyn.com/slots/bally_info/reel_strip_positioning/

since it's extremely unlikely you are going to find the tapes for the game, you'll have to make some.  What we really need is scans of all the tapes we can find so symbols can be cut-n-pasted onto homemade tapes.  The only ones I have so far are in https://bingo.cdyn.com/slots/tape_symbol_scans/

I anyone has a drawer full of new tapes, hi-res (300 or 600dpi) scans of enough of them to get all the unique symbols would be great.  A complicating factor is there's different width tapes.

maybe monte's slot shop has a bunch from the guy I knew in nevada that I could borrow to scan ...

in the meantime, making crude paper tapes with the symbol written per the M-220-20x definition would let you test the machine.

Hello, thank you for your time and all your explanations which are very clear and allow me to better understand certain subtleties of these incredible machines.
I understand better why I can't find it.

Synthetic :

• Machine has no tape in place
• The machine has no original glass
• The machine does not have an external identification plate as usual nor even a machine number inside
• Two discs out of 3 seem to be original and the third is a homemade one which does not correspond to the original roll number 1 in terms of symbols for the depths.

In addition, I focused on a Tic Tac Toe but to find out what the model is it is necessary to do the reverse investigation by noting the depths of discs 2 and 3 and what will certainly give the symbols and therefore how should be the disc 1.
It is also possible that the reed is incorrectly adjusted in depth of the right roller.

So it gets a little complicated...
Thanks again for your valuable help.
