Battery replacement in Bally Montana Video Poker Machine

<< < (3/4) > >>

rokgpsman:
Thanks, I haven't seen one in a while, wanted to take a look. Hopefully there is a static ram chip with similar pinout that can install in the socket, then run external battery power to the power pin. But sometimes it isn't that easy.

Batman:
Good evening, I had my battery chip replaced and now my screen is completely readable except I keep getting a "24 Volt" error message at the bottom of the screen and a "RAM Error" as well. Thoughts?

Badbaud:
You bought another NVRAM module?
Ebay? China? You know all of the batteries in those are depleted.
Did you try the following (see attached)?
My shop does the attached mod AND includes a CMOS clear chip and the game comes up.

Batman:
Alan, is this you? Badbaud?

Batman:
Alan, I sent you an email. I just got my board back the other day. See the email for the issues. Thanks Alan.
