Estoy por comprar la classpad 300 y necesito que alguien me sugiera acerca de su compra, actualmente tengo una voyage 200 que me ha salido muy buena, pero la verdad el dise?o estilo "pad" me encanto de la classpad, he leido mas o menos manuales de ella y topicos del foro pero aun no me decido si sustituir mi voyage 200 por la classpad, alguien a probado las dos?, me podr?an hacer una recomendaci?n al respecto.

Gracias

Im on the way for buying a classpad, im actually have a vayage200 de TI and i know of course the TI89 for the price is a good comparision to class pad, thats why y said TI89 vs classpad. Someone know about the two calculators and can say me if its convenient to replace my TI for a classpad. Actually know one thing i love the "pad" technology but i also love the funcionality of my TI. What to do?

PD Sorry for my bad english, i am still studying english, i am from Mexico

Thanks

no need to make two topics, just post the translation with your natural language (ive edited your post). if you need help ask betoe, hes our resident spanish translator

btw, i deleted the duplicate topic

Hola Enrique. De que parte de M?xico eres?
Ambas calculadoras son muy buenas, cada una con su muy particular caracter?stica. Podr?as hacer un an?lisis de que uso le das y si la classpad te satisface tus necesidades, pues bien podrias comprarla y tal vez vender la voyage (si yo estuviera en tu lugar y tuviera estabilidad econ?mica, me quedar?a con las dos).

In english:
Hi Enrique.
Both calculators are greats and very useful, with some difference between each calc. Try to investigate the characteristics of the classpad and see if its useful for your school (or work, i dunno the use you give to the voyage). Maybe if the classpad is good for you, you can try to buy it and sell your voyage (if you have a good economical level and you like both calcs, dont sell you voyage).

Gracias, soy de Celaya Guanajuato

Ahora tambien tengo la inquietud de la HP ahora si que quiero comprar un buen sustituto de mi voyage pero aun no me convence del todo la classpad ni la hp49+.

Que opinan de estas calculadoras?

[betoe]

I think aleph mobius can help you with this, he like a lot the HP49+, also he have an AFX and a TI (89 i think). Also he know a little of spanish.

Aleph mobius es un miembro de este foro (habla poquito espa?ol) que puede conocer las calculadoras TI y las HP, puede ayudarte mas en esto. Es muy probable que en la noche va a entrar al foro.

Great, i had no seen my new title, "UCF Spanish translator" .

I there, i have a HP49G and from what i know the G+ model has the same functionality but it is a lot faster and a slightly different keyboard.
if you want to see who the HP49 work download the emulator and give it a try
emulator:

and various manuals here:

I am a long time user of the 49G. I had a 48SX for a long time before buying the 49G, and I find it a nice successor. There's additions to the OS I like, and many I don't like. But in general, I like the calculator.

The 49G has a real advantage over nearly any algebraic calculator. It is RPN. Since I bought my 41CV, I have been a great advocate of the RPN model. The Voyage 200 is an excellent algebraic calculator, and I feel it is a little better than the Classpad for general mathmatic use, for the following reasons:

The 'pretty print' display shows equasions in a manner that's very close to how they appear on paper.

The roomier display makes it easier to work with tables and longer equasions.

The Classpad's touch screen is both an advantage and a servere hinderance. The touch screen allows an infinite versatility, offering such things as customized soft keyboards. But it slows input, and forces the user to juggle a stylus just to do basic input. The TI's full alpha keyboard makes input far faster and easier.

The TI's version of Basic makes it far easier to write meaningful programs with attractive user interfaces.

The TI connects to both Windows PCs and Mac OS X.

There are many more reasons I prefer the TI, but they all have to do with my profession.

I really tried to use and like my Classpad. But my profession requires a fast, easy to use calculator.

Yeah, TI is much better than the CP. I like its interface and its easy to use keyboard, more stable, less bug, also with overclocking you can reach 20MHz speed...
But I think its soon to judge about CP. Its SDP has not been released yet. So i think CP300 with its SDK is very wonderfull.

[R00KIE]

Sory, they have been changing the visual of the site and maybe it has changed, or just my mistake
the correct link is:

http://www.hpcalc.or.../emu48-1.30.zip

but this one only includes the script for HP48

you can download everything just for the 49G here:

HP 49G+ really has 75MHz cpu????
I think it's the fastest calc in the world!!!

@R00KIE: Can you give me some benchmarks about comparing CP and HP49G+ speed?

[SoftCalc]

HP 49G+ really has 75MHz cpu????
I think it's the fastest calc in the world!!!

It does run at a fast clock rate (although I don't know if it is as fast as 75MHz), but only because it is emulating an old 8 bit CPU from 1990. The original HP49 had a custom CPU, which HP couldn't get made anymore. This is why the HP49 disappeared for a while. The HP49G+ is now using an ARM processor that is emulating the original HP-Saturn processor.

The only reason it is running at a high clock rate is because it has to in order to work as an emulator at a reasonable speed. Also note that the batteries will run out much sooner.

[Daruosh]

You mean that HP49G+ is not as fast as 75MHz Calc??

[SoftCalc]

I've checked, and yes it runs at 75MHz, but since it is running an emulation of the original HP49 CPU it is effectively much slower than this.

BTW, I'm seen a software utility that will overclock the HP49. The CPU is actually rated at 203MHz!

Check out the upcoming Qonos Scientific PDA

[R00KIE]

@SoftCalc:When you say "overclock the HP49" you mean the HP49G+ right??
and the cpu isn't 8 bit wide but 64 bit but the data bus is only 4 bit wide

@Daruosh: i don't have benchmarks but from what i've seen the 49G+ is as fast or faster than the TI

and don't think that because the 49G+ is emulating the 49G it will be slower than a 75MHz CPU forever, the hp team is already porting some of the more important parts of the code to ARM native code

[SoftCalc]

@SoftCalc:When you say "overclock the HP49" you mean the HP49G+ right??

Yes, you are correct. There is a utility to overclock the HP49G+ (not the HP49) which uses the ARM processor.

and the cpu isn't 8 bit wide but 64 bit but the data bus is only 4 bit wide.

The older Saturn processor it is emulating is not a 64 bit processor because it's address bus is not 64 bits wide. It does have some 64 bit registers for doing number processing, but nothing can be read directly into these register. Presonally I would not consider it to be a 64 bit processor.

I don't know about the ARM processor it is actually using. This is probably a 32 (maybe even 64 bit) processor.

@Daruosh: i don't have benchmarks but from what I've seen the 49G+ is as fast or faster than the TI

This wouldn't surprise me, but it is really hard to make a fair comparison because they are two very different machines. It would be nice to see a benchmark test for comparing calculators that is fair and doesn't leverage one calculator's strengths or weaknesses. The HP-49G+ is a fast machine .

and don't think that because the 49G+ is emulating the 49G it will be slower than a 75MHz CPU forever, the hp team is already porting some of the more important parts of the code to ARM native code

This is also true. The HP49 team has written time critical sections in native ARM code. I'm assuming that there will also be new code written for the new ARM processor. Still, it is difficult to rewrite much when your hands are tied to an old operating system.

Who knows what the future holds for the HP49G+ and beyond. The hardware is very impressive and it is amazing what the designers have done to get the older OS running on the new hardware. It is a fast (and very cool) machine .

I own one and I love it, but then again I also own a Casio ClassPad, Casio AFX 2.0, TI-89, TI-Voyager, HP-48, HP-49...

[qwerty841]

The HP49G+ is now using an ARM processor that is emulating the original HP-Saturn processor.

Isn't that processor used in PDAs?

[SoftCalc]

Some PDAs have an ARM processor.
Some PDAs have an SH processor (like the ClassPad )

[betoe]

is not a 64 bit processor because it's address bus is not 64 bits wide

The number of bits is determinated by the data bus, or i'm wrong?

[SoftCalc]

Why not try them both? You can try the ClassPad by downloading the ClassPad manager, and you can probably try out the TI-Voyager by downloading the TI-89 SDK.

SDK stands for Software Developer Kit. The SDK for the ClassPad should be available very soon.

[Daniel (CZE)]

For TI there is also an emulator: VTI 2.5 Beta 5. It can emulate many types of TI calculators (but I don't know if there is V200 too. It doesn't matter because V200 is almost same as TI-92 Plus)

[Daruosh]

Does it require ROM Image???

[betoe]

@hank el tanque:
If you feel better talkin spanish, contact me via PM, posting here or by my site.

[Daniel (CZE)]

<{POST_SNAPBACK}>

You can use ROM Image or OS of calculator (it can be downloaded from TI Website)
