I have an Mv-4f that I recently repaired so that it would pass the backup ram test (replaced both chips). It boots and plays fine now, and saves the calendar info, but soft dips (most notably the cabinet settings) aren't being persisted.
The board has a unibios 3.0 in it and the backup battery was replaced long ago with one of the CR2032 kits from JNX. When I did the repair I replaced the battery, cleaned up some corrosion around the site, and replaced an electrolytic cap that was corroded and had a hole in it.
What's the best way to troubleshoot this? Why / how would the calendar work fine and not the backup ram?
