Full Version: HP49G+ vs HP49G
You're currently viewing a stripped down version of our content. View the full version with proper formatting.

Is there a comprehensive side by side comparison chart?
Or a link to a good comparison of abilites and differences?
I am interested in features, hardware components (like what processor is used?) etc..

Please visit www.hpcalc.org , and read the newsgroup comp.sys.hp48 .

The two above are *the* sources for information on the HP-48 and HP49x series calculators.

BTW: If you don't have neither the 49G nor the 49g+,

just forget about the 49G, which is simply trash IMHO.

The 49g+ is far superior to the 49G in *every* aspect.

Faster, better display, much better keys, much nicer look (no frozen hamster butt),

expandability (SD cards), more programming options (ARM core access), and more...

I'm not so sure about the keyboard. I don't like the feel of the rubbery keyboard on the 49G and it occasionally misses keystrokes, but the 49g+ misses a lot more keystrokes, and already there have been numerous reports of broken key hinges.

But in other ways, yes, the 49g+ is superior.

Hi James,

> ..Keys..

That's why I don't use either of them;-)

My favourite in this class is my HP-48G+ Turbo,

with the high contrast display, a reliable keyboard,

with a real ENTER bar, speedup,
,and more RAM than needed...

Regards,

Raymond

HP49G+ is an upgrade of the HP49G:

* A SD Card Port
* Faster Processor (I'm not sure what MHZ)
* Price $139 as opposed to $189.

The big con, the keyboard can be a problem, but I hear that HP has fixed the keyboards.

Perhaps, but I'll believe it when I see it. My second warranty
replacement 49g+ has a package serial of CNA423xxxxx,, case serial
CNA419xxxxx, and ROM serial CN420xxxxx, and still misses
keystrokes if I type normally. That said, if I'm careful to
"bottom out" the keys every time, it does register all keystrokes,
so I think that a lot of the problems depend on the user's typing
style.

Whether they've fixed the problem with key hinges breaking will
probably take a few months to tell.

But if you want to read discussions about RPL calculators, you'll
find a lot more information in the usenet group comp.sys.hp48.

James

I prefer the hp 49g+ for it's speed
and the I/O speed plus the SD-card.
Also new SW is focused on the "plus".
