I recently bought a new NiMH battery and a USB charging cable for it so Alright, then, you might be the right person to come up with the final answer to the question this thread is all about: which decimal points are lit when the battery charge drops below a certain level? Do they just invert, as WalterB suggests? Or do they show up in the way the HP-35 manual states (see attachment)? One more question: if you plug in the power adapter, does the battery warning disappear immediately, or only when the battery charge crosses the trigger level again? My guess is that HP chose a simple hardware solution: XORing the decimal point signal with the output of the voltage detector. No software involved at all. I'd love to make my HP-35 simulator behave like the real thing. |
