Hi there!
Got my hands on a HP-48GII (s/n CN33501390, V1.20) and a HP-49G+ (CN33904081, V1.23) and observed this:
Both units have a strange behaviour where the display seems to be redrawn about 3 seconds after the last change of the display contents. This is especially nasty when the blinking edit-cursor is visible because it constantly triggers the display refresh. As a consequence the blinking cursor does not blink steadily but more or less randomly.
Also, on the HP-48GII the bottom row of soft keys gives a visible "blink" when the display is redrawn which is rather annoying.
The old HP-49G does not show this behaviour.
Has anyone else seen this?
Is there a software upgrade which would resolve this issue?
Also, since the software versions are both "HP49-C" am I right assuming that the only difference between these units is the amount of memory and the additional SD flash card slot of the HP-49G+?
Thanks,
Tony
