Schematic Bally Proslot 5500 Slot MPU Board type AS-3356-201 anyone?

[John Bally]

Does anybody have a schematic of a Bally 5500 slot MPU board type AS-3356-201?

I need the same schematic also. Customer brought in a AS-3356-201 board after they tried to de-solder the cmos battery themselves and burnt all 4 pads off the board. I need the schematic to trace where the neg. side goes to in order to jump it. Thanks

I would like a copy of that schematic also.
Thank You !!

That schematic is in the "Download" area.
The neg side of the battery connects to the common ground.

Thanks!

I don't have access to the downloads section... I think.

The download section is available for contributing members
which by making a small donation you too can be one.
But the schematic only shows the neg side of the battery
connecting to the common ground.

[SomeRandomTech]

And you were correct! It was the common ground, so I bridged the neg over to it. Interesting that it goes straight to ground. I would have expected a separate circuit only supplying power to the NV ram, or similar, but instead the 3.6v can be traced all over the board, this seems very odd to me.

A contributing member? Maybe, what does it cost?

Thanks.
