Hi, my name's Ben and I've been learning and lurking for a while.
I've got a couple of boards with issues I wondered if someone might be able to help me with?
I'm getting garbled text on the 1B and the Calendar Error on the 1C.
If anyone knows what the first course of action is for either or both I'd be very grateful. I know there is the battery replacement option but both boards have been running without an installed battery fine until very recently and now these issues.
Hello to everyone and thanks for any help.

Check the traces to your SFIX chip, specifically the address lines.

Great, thanks. I'll have to locate those first but much appreciated. Do you know if there are schematics for the boards anywhere? Ben
