Battery replacement in Bally Montana Video Poker Machine

<< < (2/4) > >>

Badbaud:
Ya, they are Dallas NovRAM chips with the battery built inside. They can sit on the shelf for years with no battery degradation but the battery connects when power is first applied.

I know, I used to design with those and gave Larry my last 10 when we ran out. We have 4 left, you are getting two. That leaves two left in stock.

Some day I am hoping to get a Maverick into the shop so I can design a work around and eliminate the necessity for the obsolete NovRAM.

I looked over his photo of the cpu/mpu board, where is the Dallas chip located on the board?

Badbaud:
Lower left of photo. Along the edge, counting from bottom  left corner Count 7 blurred rectangles up to a black rectangle, that is the NovRAM.

Would that be my index location #7 on the photo below?

Badbaud:
no 6
