Help with identifying this converted Bally game? History of the machine and manufacturer DAT?

Next time you have the reels out of the chassis.
Examine the index arm rollers for mobility.
Reason being the index disc slots appear to be hammered at the outer edge.
As I mentioned before, disc can be slightly altered to favor one slot over another.
In your case all the slots look hammered from what is visible in the photo.
Indicating a slight malfunction.

Mentioning pinball machines, I’ve brought a few back to life.
Find them a little more of a challenge electronically, but not so much mechanically.
This Cinema machine had a little bit of everything wrong with it when I got it.

Here's some pics of the inside of the top box





I didn't realize the payout labels were printed on paper at first, but I suppose they are. I am guessing the bottom glass is the same way? Maybe so people could change the jackpots over time?


I also went through and spun each reel around and mapped out the symbols. From what I can tell each reel has 25 spots on it. These positions are mapped based on the visible seam of the reel strip. Here are the order of the bars, melons, and 7s:

Code: [Select]

Position Reel 1 Reel 2 Reel 3
1 B B B
2
3 B M
4 B
5 M B
6 M
7 B B B
8
9 B
10 B 7
11 7
12 M
13 B
14 B B
15 7
16 B B
17 B
18 B B
19 M
20 M B M
21
22 B B
23 B
24 B B
25

From what I see, all payouts look to be regulated through the wiper boards.
Wiper boards are well utilized with jumpers to the eighth row.



Only 2 payout strips are being utilized on the payout step up unit, the 20 pay and 100 pay.

your reel tapes match two sets of tapes:


m-225-[75,76,77]
m-225-[78,79,80]


a note on the docs says the difference is the 78-80 tapes use the 20 stop tape symbol size at each position.  The 20 stop symbols are a little bigger, and they can use those in this case due to the blank cells on either side of most of the positions.


the 831-ZE used the 78-80 tapes and I have the paperwork for that game.  I'll try and get it posted for download in the next day or so. 


there's a bunch (more than 20) of other variants of the 831 that used those tapes also, so the next thing to narrow it down is what is the M-645-xxx number on the payout counter disc on the hopper.


appears the DAT company was making 831 "1767 way" machines out of whatever they had available for parts.


mvco needs a little tweak to his post ... he shoulda said "Looks like it ended it's life as a Bally 831 model" :-)

I've been reading through this thread, and even though it's a different bally machine it's still helping me with my knowledge about payouts.

put paperwork for the 831-ZE and 831-ZP on http://bingo.cdyn.com/slots/


except for the schematic, the diagrams are the same for both games, so the files are mostly in the 831-ZE folder.


a major difference between the two games is the ZE ... at least on this schem ... uses the new style hopper while the ZP uses the old.


oddly, the ZE schem is w-1046-1808 while the ZP is w-1046-1017.  In addition, the ZP schem says "831 ZE" on it.  Oh well.


the top row of lugs on reel 1 wiper contact plate diagram labeled "ext" go to the payout counter disc.  Those traces aren't used on your game and looks like the refurb company didn't bother running the wires.


as you can tell from notes on the diagram, the same drawings were used for many games.  In this case, I have two different versions of the w-1041-1939-1941 diagram.  When they redrew it, the left off one note and added another.

Thanks wolftalk! I downloaded all of the files and I will give them a look. I am unfortunately caught up these days moving out of my SF apartment. I will get back to my projects soon, but I need to be out of the apt by the end of the month.
