HP Advantage Module...



#21

Hi there,
Does the HP Advantage module include a Math module in it?
Thanks,
Andreas


#22

The Advantage module does not include the MATH module per se. It does offer other mathematical operations like SOLVE (coded using fast microcode), INTEGRATE, Matrix operations, and oher calculations. The Advantage module brought to the HP-41C/CV/CX features that appeared in the HP-15C which many felt were very importaant.

Thanks Namir,
I thought so. But I bought an HP-41CX on eBay where the seller claimed that it would come with a Math pac module and an Advantage module and it didn't. When I challenged that, he said that 'The math module is already in the calculator. It's the HP-41 Advantage'. There are so many crooks out there.

Hello Andreas,

If you want to hear about the contents of the Advantage Module, in the voice of Richard Nelson (PPC), take a look at this old posting:

and . The bank-switched ______ of the ROM contains a 59 M-CODE routine.

This ROM will be offered free to those who buy --- 41C, CV or CX or HP dealers. The Advantage
ROM will otherwise sell for 49 dollars.

exciting examples of programming for both User-code and M-code programmers. the Finance routines in user code and
Solve and Integrate in M-code. The Advantage ROM 25 menus that greatly help the user

Thanks Gerson. Very enlightening.

Hi, Andreas:

You may also want to download and have a look at my 9-page article
Long Live the Advantage ROM! in PDF format, which reviews its most important features and includes a sample program utilizing to the fullest some of them.

It will probably give you a fair idea of what it is, what it can do, and its programming style.

Best regards from V.


#28

Valentin,
Thank you so much. Very nice work on the PDF documentation! I might have to return the machine with the Advantage module though. If I get Clonix would I be able to get the ROM downloaded to it? Also, I have another quick question: when I do an EMDIR on the CX, I only get 124 registers. Is that normal? Shouldn't I get 600?
Thanks again,
Andreas


#29

Hi again, Andreas:

Andreas posted:

"I might have to return the machine with the Advantage module though."

A real pity.

"If I
get Clonix would I be able to get the ROM downloaded to it?"

I'm no expert in Clonix, there are much more knowledgeable people in this forum. I would think yes, except for the fact that Advantage is a 12 Kb ROM which does use bank switching, and I simply don't know if Clonix allows for this or not, though I'd guess yes. Let's the real experts talk.

"Also, I have another quick question: when I do an EMDIR on the CX, I only get 124
registers. Is that normal? Shouldn't I get 600? Thanks again, Andreas"

It's perfectly normal. To get 600 EMS registers you would need to plug in two EMS modules, each one of them adding 238 EMS registers to the 124 already built-in, for a total of 600.

Best regards from V.


#30

Valentin,
Thanks again. Is it true that those are Extended Memory registers? In other words, the HP-41CX still has four times the memory a regular HP-41C has, right?
Regards,
Andreas

Hi, Andreas:

Andreas posted:

Yes.

"In other words, the HP-41CX still has four times the memory a regular HP-41C has"

Five times, not four: 320- versus 64-, where the "-" means part of the 320th register (64th register) isn't available to the user.

Best regards from V.

Andreas --

Getting an HP-41CX with Advantage Module is pretty good. You might consider keeping the unit, even with the absence of the Math Pac. Math Pac's were widely sold, being the most basic upgrade, and can routinely be obtained on eBay for < $20, complete. Even better is a combined Math/Stat Pac.

The Advantage Pac has much of the the functionality from the Math Pac, but does lack a few items, including triangle solutions, Fourier analyses, and hyperbolics.

The Math Pac contains 4 kB of code, all of it as RPN routines. The Advantage Pac contains 12 kB of code, much of it as sophisticated, faster-running microprocessor code.

On X-memory: 124 registers of X-memory is built into the CX. Two 238-register X-Memory chips are required in order to achieve the maximum 600 registers.

Oh, wow. This is awsome. I loved it. Thanks Karl. Well, maybe I should learn how to use the 'Search the Museum' link. (!@%&*?) (Sorry Vassili... - I'm jokingly referring to the post that set JE off...)

If you didn't like that 41CX, you should consider keeping the Advantage Module if you get it for a reasonable price. Although you can have the Advantage for free using Clonix, I think the power consumption would be somewhat high compared with the original ROM module. On the other hand, people who use Clonix and other peripherals a lot generally rely on rechargeable Ni-Cd cells, so power consumption would not be a problem.

Gerson.


#35

Gerson,
Thanks for the reply. Why do people still use Ni-Cds? Can we not use Ni-MH or Lithium cells? (Is there such a thing?)
Regards,
Andreas


#36

Hello Andreas,

You may use Ni-MH cells, but they have to be recharged outside the calculator, on a charger specifically designed for them. By what I know, lower capacity Ni-Cd cells are still used because they are compatible with old rechargers. The only lithium cells I know are those button-type 3V batteries. There's a lot a past threads about the subject, the easiest way to find them is doing a google search for, say, site:www.hpmuseum.org Ni-Cd batteries.

Regards,

Gerson


#37

Gerson,
Thanks again for all your time and valuable info. Very much appreciated. Do you know how all this info shows up at Google almost immediately by the way? I alos assume it was one of Dave's decision to use whatever method to have all that info posted.
Regards,
Andreas


#38

Google just keeps the whole Museum site (and zillions of others) indexed on a regular basis. I don't know how exactly they do this and I think they wouldn't tell us, or would they? :-)

http://www.google.com/technology/pigeonrank.html

Now, seriously, there's also a search tool in the Museum:

Search/Personalize

But I confess I don't remember how to use it.

Regards,

Gerson.

Being from Europe originally, and still keeping abreast all the news developments, I have been listening to tons of news stories lately about bird flu in different countries there. If the avian flu crosses the Atlantic (with the rate it exists in Europe), I worry that Google's results won't be as accurate any more. Maybe the scattered reports of avian flu lately in the U.S. might be the cause of their stock decline lately!

(I really enjoyed the article...)

#40

The battery contacts of the CX are corroded. If I get to keep the machine, is there any way to tell if the battery acid/base might have spread inside? Does anyone know if there is a fairly easy way to open the machine without breaking anything? If the machine works now but the liquid has spread inside, are there significant chances for the machine to die soon?
