Hello, I am working on a Joker Poker and having an issue with HSTD and saving credits/settings. I first took off the battery and installed a remote 3.6vdc battery. That went fine with no issues. I can now get it to kind of save the HSTD but it looks garbled. Also the credits will not save when I turn it on or off. Here is a phone of the garbled HSTD. Is there an IC I should try swapping?
