HP49G vs HP48G+ or GX



#2

Hi
I have an option to pick up a new 49G for US$140.00 which seems like a bargain. What I'm wondering is, given that the 48G has inbuilt forms and a virtual Cult following in terms of Applications available on the Internet, is the 49G worth it? Also, although I currently have a 17Bii, I have not made a great deal of use of RPN. Is this a drawback regarding the 48G or GX?


#3

You have started a big thread in here. Many will put their impressions about the HP49G.

I have both, 48G+ and 49G. To be completely honest: I do not like OPERATING the HP49G, cause it is somewhat hard to type in stuff, BUT it is the best portable, trustable active MEM space to hold stuff. I develop in the 48G+ and test, store in the 49G.

I do not have any business machine, so I cannot give correct opinions about the 17BII.

#4

I also have both. If your new to RPL then the manual for the HP48 will be best, the HP48 also has a good advanced user guide. Much of the HP48's documentation transfers over to the HP49G so it might be best to get the HP49G calculator and the HP48 manual! If you do go for the HP49 be prepared to spend some more money on a good book or 2, the HP supplied manual is very poor.

For another book on the HP49G try:
Science and
Engineering Mathematics with the HP 49G - Volume 1
by Gilberto Urroz
Publisher: GreatUNpublished (www.greatunpublished.com)
ISBN 1-58898-043-X

You can program /test on a PC and then transfer the program to the HP calc.

The '49 appears less robust than the '48 and the keyboard is not very nice but does come with lots of memory and extra mathematical functions over the '48 (but no equation library)


#5

Tom from UK (others are welcome)

Please tell me more about the Equation Library. Is this a feature on the 48G+ or GX that outweighs the extra memory of the 49G? Is there some way to compensate for this equation library, such as other programs?


#6

The equation library on the HP48G/+/X is a collection of useful equations grouped into areas like:

Optics, beams, electronics, projectiles etc.

The user inputs some of the variables and the calc works out the unknowns.

The HP49G does not have these (people guessed that HP removed them so the HP49G would be allowed into more exams - but alowing a calculator with 1M of memory that can be stuffed full of pages of text is a bit of a joke in my opinion... equations make a tiny change in the ability to cheat with the HP49G or HP48G if your that way inclined)

There is no reason why the equation library could not be loaded into the HP49G - I assume HP own the copyright so it would be up to HP. HPCALC.ORG has many programs, have a look if you can


#7

There is always a chance to load all equations (maybe the GROB´s, too) in the 49´s FLASH memory, so it will be safe from a Memory Clear. Even better if jus a few (or only one) subject is needed. I don´t know if the complete library is available to download anywhere or if it would be necessay to select each equation (or group) and reffered GROB, build a small database, a mannaging program and, then, load them into the 49`s memory.

Suggestions? I´ll be thinking about it.


#8

There are programs for the 49 that replace the equation library. The only thing it is missing now is the IR port ...


#9

...and the keyboard;-)

On the 2001 production models of the 48G series even the display is the same as in the 49G...

Regards,

Raymond

Since you have a 17BII, you can certainly try out RPN since this calculator can operate either RPN or Algebraic.

What exactly are you looking for in a calculator?

If you want all the bells and wistles (even for the sake of HAVING THEM, many of us are in this catagory), Buy the Hp49G (ok, it doesn't have eq lib). It is actually much cheaper than a 48GX if you later buy a RAM card.

Also the 49G does have algebraic input.

Now for some bargain tips:
THESE are not for the hard core HP RPN user, but since you have indicated that you use Algebraic on your Hp17bII, you may also consider these next three calculators.

1st to consider may be an Hp19bII. It is not a big step up and costs almost as much as a discounted 49G, but it is exactly the same as your 17BII for operation, but also has Trig, notepad, and units converstions. All nice extras and you wouldn't have to open the manual to use this calc like a pro.

2nd is a Graphics; Hp38G, Cheap (certainly less than $50, and maybe less than $25) Still has the Hp quality feel, is Algebraic only, but has plenty of MATH functions. Sadly doesn't offer any other features such as a Finance solver or units conversions. Has only 32K.

3rd is an Hp 39G, a near look alike of the 49G, but algebraic only without CAS or RPN. Also without units conversions or a built in Finance solver. Very similiar to the Hp38, but with added functions and 240K RAM. List price is $80 and are usually sold for much less.

Both the 38 and 39 have Hp solve so you could add nearly any function you want easily or program in you functions with Basic.

If you use or like RPN, the last two calculators are NOT for you. Also the solver on the Hp38 & 39 can only use a single letter name of 27 available (A-Z & theta).

Since you indicate you like your Hp17bII, play with a 39 or 49 before you buy either, since they FEEL different from the older Hp calculators. In fact they FEEL different from each other. I don't mind the 49 since its rubber feels much stiffer and has some tactile feedback vs the 39 feels like a spongy rubber keyboard. Neither feels as good to ME as a 48 or 38.


#11

This kind of indecision makes the HP collectors

Buy them all!

Marx Pio


#12

I second the motion to "buy them all" and would add "and get several of the older models, I'm afraid they are nearing history!" Some of the 48G's have sold in the $2X range recently, simply amazing for the HP HP (horsepower) in them.
