New Version of the HP-39GII



#32

I was looking in the usual places on www.hp.com where I might find an entry for the HP-15C LE with an active "Add To Cart" button. Scrolling through the entries at http://www8.hp.com/us/en/products/calculators/index.html I stumbled across the following:

Link to HP 39GII Product Page

If you look closely, you'll notice that the soft menus in the image are in Chinese characters. These could not possibly be rendered unless the display has a higher resolution that the current HP 39GS.

Maybe those luck few going to HHC2011 will get a look.


#33

Well, at least its something new. The colors are "meh", and the keys look like Casio rubber keys. Although i like that they put all the labels onto the keys so it looks less cluttering. But that probably will mean they will wear off sooner. Also the cursor key (SINGULAR) is a disappointment.

I do like the overall shape and the border though. Its not all swoopy curves and other laughable styles from 1999 (Ford Taurus anyone?).

If they could take this, color it black, and style the keys similar to the hp 35s. I would look into it.

I'm waiting for a HP-50gii with a large ENTER key in the correct location and a color backlit screen.

And that correct location is above the * / + - keys. The ENTER key and the basic math operation keys should always be on the same side of the keyboard, the way they were for the first ten years of HP calculator history. I don't care which side of the keyboard the basic math ops keys are on, but the ENTER needs to be there too, above them.

At least the HP high-end scientific models for the past decade have the ENTER on the correct side, but not at the correct elevation.

#36

Gone are the horrible curvy stuff, and instead a nice geometric design. Looks very classy. Traditional colours too!

Where does this sit in the range?


#37

Hmmm... The display looks good, but the body... look at the bottom, it looks very much like the 30b... I really hope it doesn't have the same heavily slanted sides!!


#38

Looks really as using the same kind of casing as the 300s. The dimensions match quite perfectly. The colors are less childish, let's hope that the keyboard will be made better!!

#39

At least this one isn't a printer. :)


#40

Hello,

What do you think of the HP circular logo?
I personnaly regret much the usual rectangular one!
Did the designer find the calc needed some curves anyway?
Kind regards.


#41

The logo is too shiny

#42

Well spotted Mark. A new case and screen res for the 39 means a new case and screen res for th 50g as well. HHC2011 is looking to be very interesting indeed.

#43

Waoooo !!!

What a screen ! I want the same on the HP50G :D

Seems something like 320x200 ( ? I must calm myself lol )? The détail in the soft menu are fine !

My wishes for an HP51

- This screen
- more RAM
- RPL improvement
- More fast

Hummm but that's just an image and for a 39GII... wait and see !

But seems very very interresting !

320x200 and monochrome would give it almost 2/3 the pixels of a Palm Tungsten T (320x320), which was released about 10 years ago. Be still, my heart.

As the above message does not show, I am glad to see a new graphing calculator from HP. The case looks better than its predecessors (are we finally getting away from the "gratuitous curves at all costs" era in electronic device designs?) and it could be a good alternative to TI calculators.

Keyboard quality remains to be seen, as is repurposability. If the processor and memory permit it, one might see an enterprising hacker port Linux to it.


#46

"Waoooo !!! What a screen !" ???
"It could be a good alternative to TI calculators" ???

Hard to believe. Sorry, but where you live? The life is colored and the newest TI too !!!

What about HP?


#47

The TI Nspire CX color display is very pretty, but my HP 49g, 49g+, and 50g with their monochrome displays have very long battery life with a few inexpensive AAA cells. The TI needs to be recharged quite frequently.

I guess if you are accustomed to charging your other devices frequently, then charging your calculator too might not be such a bother.

On the other hand, if the batteries in my 50g run low during an exam, I have a spare set in my backpack. With the TI, I'd be SOL.

If HP has put a higher-resolution monochrome display in the 39gII, the reason they chose that over color is almost certainly battery life.

Someone speculated that the 39gII display might have 16-level grayscale. I haven't seen a 39gII in person, and am not privy to any details about it, but I suspect that it will turn out to have hardware with no grayscale support, only high-resolution monochrome. That would mean no antialiasing on fonts, but since the resolution is probably around 173 dpi, it should look pretty good despite that.

Based on comments heard at past HHC conferences, I suspect that this is probably not running RPL-based software derived from the 38/48 series, but rather an entirely new code base in C and/or C++.

It seems pretty straightforward to re-implement the function set of a 39G in C but this way, a 40gII will be a really big effort to do. The same will hold for a new 50G.

Is there some big difference between the 39g and 40g other than CAS? There's plenty of C/C++ CAS software out there.

However, I expect that a ground-up rewrite of the 39g, if that is what happened, probably took a lot of man-hours of development time. I'm not sure what you have in mind when you say "pretty straightforward", but it's not a small project.


#50

I was talking about the CAS. If you replace it by something completely different, there are chances but a rewrite from scratch with the same functionality seems to be a very big task.

OTH, the basic functionality of a 39G is limited (which is not a bad thing given the audience) and it may be the easier path to re-implement it then to do another Saturn emulation and try to fix an old firmware for the new screen layout. Maybe a combined approach (Saturn virtual machine for CAS) is possible.

#51

Is only the rewrite respectively the re-implement of the 20year old alg48 (respectively erable) the right way?
I think we need some elements of innovation or advancements ...

#52

Eric, I agree.

I'm not interested in a color HP50 but higher-resolution monochrome display in the 50 would be very nice.

#53

Would you buy a new handy with monochrome display to have a longer battery life?
Would you buy a monochrome television instead a colored flat-tv due to price?
I think no!

Nearly everybody have a handy and is accustomed to charging it frequently (every 2-3 days). Why do not put the calculator frequently in docking station?

With a colored display you can distinguish several graphs easier (for example function, derivation and anti-derivation).

My suggestion:
HP should build two mode in the calculator: a monochrome and a colored mode.
So the user could affect the battery (respectively accu-) life himself.


#54

I would definitely buy a new graphing calc with a monochrome display. The 50g's screen has a great contrast, and is perfectly legible. And its grayscale is very good. If they could double (at least) the resolution (4x no. of pixels) it would be great.
And yes, I would very much prefer a long battery life with common batteries. I keep my calc on my work bag at all times, ready for when I might need it. I don't want to (and I would forget to) recharge it often. Plus, standard replaceable batteries are the best when they run flat "on the road"... AAA batteries can be found everywhere. A socket and charger, no.
Same goes for my trekking-handheld GPS: I only buy units with standard AA batteries, and I've often had to replace batteries during day-trips.

And as far as I know, monochrome and color displays use totally different technologies; sending a monochrome image to a color screen, it would still use the same amount of power. Now, if they want to experiment with color e-paper screens... :)

Monochrome e-ink displays have terrible contrast ratio, about 15:1 at best. The color e-ink displays I've seen were even worse. I'm not interested in color e-ink until they improve the contrast a lot.

#56

A monochrome display is adequate for common (algebraic) calculations.
But if you use your calculator extensive for GRAPHIC applications then a colored display is IMHO better because of the distinguishability of (many) curves and lines. And remember: This post discuss a GRAPHIC calculator.

#57

Ironically, a color screen brings back the days of the LED models with rechargeable battery packs. So, in a sense, the recent TI and Casio color displays would revive ancient calculator history. Full circle :-)

#58

Yes, and therefore i sell my pc and iphone and go back to the HP 200 LX. It have all the things i need: A file manager, Lotus 1-2-3, Pocket Quicken, a scientific calculator, a simple word processor, a very powerful database application, a note taker, a few games, Laplink Remote Access, a terminal emulation....
AND: All this run on a full MS-DOS 5.0 three weeks with only two inexpensive AAA cells.
Because i don't often reading the screen in dim or dark environment or in total darkness furthermore i don't need a backlight upgrade.
And to phone someone on the way i reactivate my good old (monochrome) Nokia:

Life can be so easy ....

#59

Just checked the page - selected all RPN models ... AND THE 15C IS LISTED HERE !!

Model mumber looks 'intersting' though...

Edit - Just checked, the US site lists 11 RPN models - UK site only 7 :-(

Maybe I'm starting to "get old" but I find the new design to be mostly ... UGLY. Ugly colors, ugly key layout, ugly material (is that rubber in the keys?1)... you get the idea. Mind you, I started with HP calculators with the introduction of the HP48G series and then later started to collect the older Pioneer models. Though some of the even older HP fanatics consider the HP48G series "ugly." I guess it may be that I am biased and prefer the design that I am most familiar with (the Pioneer models and the HP48 series; they all share a similar keyboard and case design).

The newer calculators with slanted sides (who idea was that?!) ... I will never understand why. I just don't understand how these new designs would ever be considered "cool."

It's hard to tell what sort of keys those are from a single photograph. Rubber keys would be a bummer, I agree. I can see at least two features that I like, in addition to the higher resolution display. First, the color contrast of the shifted key label is excellent, in my opinion. Second, the case design is rectilinear, which appeals to my techno-geek sensibilities. (The curves on the 50g et al appeal to my artsy/fartsy sensibility, but I have my geek on today. :)


#62

I definitely like rectilinear shapes. But I definitely *dis*like slanted sides! :(
