HP 35s On/Off /Clear x reg Key



#5

I don't know why I didn't notice this before, and sorry if this has been discussed already.

The key at the bottom left is labeled C in white letter and a blue -colored "ON"; it has a yellow-colored "OFF" above this key. Well, I think the "ON" label should be white as well.

Also, with the 35s turned on, I can turn it off using either sequence:

Shift-right

C key

or

Shift-left

C key

I never paid any attention to this when using my 32sII. This must be by design, as my 32sII also exhibits both OFF sequences.

Cheers!

"DavidB" --

This has been mentioned before; it's a detail that was overlooked in the HP-35s , but not in the predecessor Pioneer-series models (e.g., HP-32SII), or even the HP-33s.

This may have been partly due to expedience in manufacturing: Only yellow is printed on the faceplate, but "a b/c" doesn't require the yellow shift key.

As you noted, either the yellow shift key or the blue shift key will work when turning the calc off. One can also pointlessly press the blue shift key prior to turning it on. So, the respective printed colors of "OFF" and "ON" are not technically incorrect, while "a b/c" in yellow actually is.

The ab/c is not yellow on my 35s, but orange (like the alpha markings). Presumably this is to indicate that these functions are not related to either shift key, but their use is dependent on certain context of key input.

Oh! So it is. (Darn that bad lighting...) So, why didn't HP just use white, as they did in the HP-32SII?

Probably so, but for consistency, "ON" could have been printed on in white on the faceplate, as it was on the HP-32SII...
