Welp, one of my 4 batteries died today (no worries on the memory on this model). I found a spare battery, but between that and switching back and forth to USB power, it does seem the calculator’s speed might be lightly affected by voltage levels and even possibly by temperature.
Yes, as in the studies of everything between keeping up with time zone rules, knowing when the next lunar eclipse is (in the USA that’s coming up shortly early morning March 14), and even learning and understanding how long different CPU instructions take.
Apparently I study timekeeping so much that I can program a clock on a graphing calculator without using any timer function.
It takes a fixed amount of time to alter a pixel on the screen, and when carefully crafted, the pixel clock itself serves as a timer.
I’m actually currently testing such a clock demo on my Casio right now.
are there significant differences in pixel response as battery voltage goes down?

Hey, ain’t nothing perfect…
I guess it doesn’t matter since you can’t look at it with a dead battery anyway.
Very good question!
At this moment I don’t know for sure.
I’ve only been running it on consistent 5V USB power until yesterday.
I am keeping the voltage level question in mind though…
Timekeeping?
