HP 17 BII ++ (silver)



#17

I just posted some photos of HP 17B II ++

For me, the most striking feature is the (almost exact) same form factor than Pioneers. In the photos I used my 42S as an example.

The 17 BII++ has all the hardware to support 42S functionality: The display is similar, the keyboard layout is the same, there are a buzzer and an IR port. The only (albeit major) issue for a XXI century 42S is the migration of the original software to the currently available processor.

The 17 BII++ comes with a nice leather case, with a closing flap and a magnet button to keep it closed; and with a rather good manual, comparable to the 35S manual.

The silver edition looks good. How is the keyboard and are there any additional enhancements (compared to the current brown 17BII+)?


#19

The keyboard is good, similar to the HP 35S in shape, key spacing and size, and feel.

I don't have information about the "brown" HP 17 BII+, I suppose there are no functional differences.

#20

Andres is right, there are no functional differences between the brown 17bii+ and the new silver one. The solvers are the same as well.


#21

The return of the big INPUT key is great, but the silver housing is a shame, I farely prefer the golden/brown one. I'm keeping the first one even with the smaller INPUT key.

One question btw, have the buggy L() and G() functions been fixed in this new edition ?


#22

What I like most of this model is the form factor (including keyboard and display), I hope HP will use this format for scientific models. Colors may be changed easily when deciding new models' features, but the whole issues of case and keyboard production are not so easy to adapt. This format is great and, just like the old Pioneers, could be a platform for many models with different features and, yes, colors.

It depends upon what you mean by "buggy L() and G() functions." These two functions did not work at all in early releases of the 17bii+, if I recall correctly, but they have worked for some time now in the current models (I bought my "brown" one about a year ago, and L and G work fine on it as well as the new "silver" edition).

The solver in the "brown" and "silver" versions is the same, and it is different than the solver in the original 17bii. The current solver ALWAYS iterates, it never uses the direct solver, as far as I have been able to tell. This means that it will always evaluate a solver equation at least twice, and if you adjust the value of menu variables within your solver equations or fail to initialize internal variables to 0, you may not get the values you would normally expect. This behavior is different than the behavior in the original 17bii, which always works "correctly."

For example, the equations in the Technical Applications for HP-27S and HP-19B for prime factor and lcm/gcd work fine on the 17bii, but do not work (without modification) on either the "brown" or "silver" 17bii+. I have a modification if you are interested in those.

Well, you answered my question straight away, the bug is still here. I never need L or G anyway, so that's not a real problem, since there are so many other ways to program things in this solver.

How is the screen like? Looks better than than the 42's (contrast-like)on the pictures, but is it a non-glare one?

thanks,

reth


#26

I'm in a hurry and will not be available for the next days.

Contrast is better than the 42S. I submitted a prior response, but it seems to be lost in the Forum, I may have made a mistake when finishing the post.

No missing keystrokes, but sometimes, when the clock is being displayed, the first keystroke only serves to call the calculator appliction back, and that may be a little confusing. Also the stack behaves somehow different from traditional models, but that is a documented feature, not a defect.

It's a nice and promising platform, to put it in few words.


#27

thanks, I guessed so about the contrast, how about the screen surface - is it mate, non-glare or shiny like on the 35s?

cheers
reth

#28

Muchas gracias, Andres!

#29

This model looks very nice. It may certainly be a promising platform for more to come. I'd second Reth's LCD contrast question. Furthermore, did you have time to check for missing keystrokes?

#30

Why oh why won't they release this calculator in the US? What's the reason for that, does anyone know?

Thanks,

John

Hi folks,

I noticed something strange on my brown 17bII+ yesterday, when I press a key, the LCD contrast suddenly darkens as long as the key is pressed. I can't figure out what the matter is with it, the battery warning doesn't appear, so the batteries should be good enough and the self-test returns that the calc is OK, playing with the contrast adjustment shows the same strange behaviour, btw, the keys are hard to press and do not always react as good as expected from an HP... I think this calc was the last sequel of C. Fiorina's attempts to bring HP down to the grave.

I went to a shop today, to see the new (silver) 17bII+ and the 35s, it was like I were back in the 70's, I quite had tears of joy in the eyes as I took these in my hands. These are REAL HP calcs again, the number one is back !

I drove back home straight away to order each of'em from my favorite webshop. I feel like a kid waiting for Xmas tonite...

umm, I wonder why we don't see more shops carrying HP calculators. :)

Seriously, congratulations on your order Kareem, and be sure to post your impressions when your silver 17bII+ arrives!
