RE: HP-30B firmware backup
No, it is not as simple as reading the firmware since that is not possible.

That's the bad news. The good news is that if you can somehow find the original HP 30b ROM code then you can flash the WP 34s's firmware and replace it with that, reverting the calculator to an HP 30b.

Finding that firmware may be challenging. Unless I am mistaken it is not considered public domain.
