How long of a screwdriver do I need to open this calculator?
This is a “new to me” calculator I just got. The reason I need to open it is there was a prior battery leak , as I have found some evidence of :-(. This isn’t a deal breaker for me because it looks like it was cleaned well, but I want to open it to see if there is board damage. It’s been working fine for years as far as I know, but it’s better if I open it and make sure myself. It’s probably okay, but it’s more so I have closure on the state of the board itself. I already replaced the backup battery (LR44) as a precaution because it came with the original NL battery TI uses.
