Hi!
I started the repair of a BALLY reel, I have multiple blown ic-s on both MB and I/O boards and also some resistors on I/O. I have identified most of the blown parts, but
I have a blown IC on MB of Bally E2243-95, Motherboard AS 2978-7, P 2948-534, and I cannot read out the numbers.
 Please help me with identifying the IC on MB, the closest one to the dipswitches, (U4): I can only read out: N8T .....

And please if you could confirm also that the MB battery is 3,7V nominal?

I am sure  Iˇll need the drawings also, anyone knows where to find repair manual.

Thank You so much.

Thanks litterbox99, now i can start ordering the parts.
By the way where do you all order the obsolete parts? I understand that one place is ebay, but are there other places where  to look?

Thanks
