HP 34C - strange bug

[rprosperi]

Hi Michael,

Is it possible that the batteries are older and not holding the full original charge (they should be 1.2V for NiCD)? I had this same situation in my 34C with batteries that held enough to use the machine for a while but they were old and just not going to original full capacity.

Geoff Quickfall announced, about a year ago, that he was planning to release THE BOOK as a free, 2-volume e-book (PDF I think) as soon as he wrapped up some loose ends. He wanted to get it out before starting on his PhD, and I think that was slated to begin in September, but it's likely that COVID-19 has delayed all that, just like everything else. I've not heard any plan update.
