You will get the quotient on level 2 and the remainder on level 1. Alternately, put the dividend on level 2, the divisor on level 1, do a division ( the / key) and then PROPFRAC if the quotient is not a polynomial.

The buffer is at #80319 on the G series, its size is 256 bytes. #80519 holds the number of available chars (2 nibbles), #8051B holds any error code (1 nibble). #8051C holds where the first available character resides (2 nibbles). So you should take the byte at #8051C, multiply it by two, add it to #80319, and read (#80519) bytes of data, then substract the number of bytes you read from #80519. You should also disable interrupts while reading #80519, substracting, and writing back.

Not to the U.S. Period (they're in Canada). (ii) Although their web site lists an est. 24-48 hrs. for shipping of the AUR, *apparently* they do not have it on hand and would have to order it from HP (may they not have realized it can't be obtained from HP anymore? Maybe the next time someone *actually* places an order they'll realize it's out of print.) Still I thank Patrick for giving me hope when I most needed it :-) As an interesting fact, the AUR I got was printed in May 1994 --same month as the User's Guide that came with my calculator---. If these manuals have been out of print for 9 years, little wonder it is that they can't be found almost anywhere. ==== I've seen an ancient 'Root-Locus' question that was related to this, but no answer. My HP 49 has fw version 1.19-6, flags: { #120018685018FF4h #0h #809000400A020818h #0 } It looks like the plotting function jumps ahead to the decision that a function result is a complex number and tag it as 'undefined'. Try for example to plot the function: 1+RE(SQRT(X)), using the default plotting windor values. (it's a silly one, but the minimum necessary to see the problem)(SQRT is V/, but can be ^.5, the result is the same) Although the result of this function is always a real value, the plot only shows up for positive X values. If you look at the value table (Lshift+F6), you'll see 'undef.' for negative Xs. My conclusion is that the plot routines see a imaginary result for the intermediate value SQRT(X) function, and just jumps to the next iteration, although the final result will be a Real. Plotting 'IM(X*i)' works fine, so it seems like the problem is triggered by particular functions only, not by the presence of a complex value alone. I did browse this NG for similar cases, and already tried -3, -119, and other flags changes, and QUOTE() the function. Nothing helped. Is this a bug, or is it just right but beyond my comprehension? http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/forum.cgi?read=33334 Wow! also see this one: http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/forum.cgi?read=33347 49gii ==== > http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/forum.cgi?read=33347 Steven says that It was a PDF showing the 33S, 17bii+, 19bii+, 12c Platinum, and 49gii, but what about the 38/39/40 line?

I can only see one extra blue key: the plus key. It looks as though they have moved LST x onto + and put = as blue shifted ENTER but it's really hard to read. There are three additional orange shifted keys: RPN and ALG on CHS and EEX respectively and, trivially, OFF above the ON key. The other big difference is that the plate that the keys poke through is platinum, instead of black. The screen surround is also platinum instead of gold and has the model name and number printed onto it instead of being on the HP badge. There is an annunciator showing for RPN which probably means that it defaults to algebraic. :-( I see that they made it quicker. I wonder if they will encounter the same user resistance as before or whether the users have moved on and expect things to be faster? -- > There is an annunciator showing for RPN which probably means that it > defaults to algebraic. :-( > But in the 12CPt manual RPN seems to be preferred.

The first part of the basic calculus marathon is at last ready and uploaded to hpcalc. It contains the technical part of the commands d (curly derivation d), DERIV and DERVX, in combination with partial evaluations, expansions, SHOW and QUOTE. (There are more combinations than you might think, each of them has its usages and advantages.) Also some small programs for different purposes. The most useful of them is (IMHO) the program that takes derivativbes like dSIN(X)/dCOS(X). (Oh yes, such derivatives do exist and are very very interesting.) We have also some other stuff, like finding if a given function is differentiable in some particular point, and similar stuff. Oh, and not to forget, we have the Weierstrass function, fascinating. Because the programs are really small, this time I didn't include them in the zip-archiv. The next part, however, has some bigger programs, and so I'll include them all when it is ready. ==== What calculator? 48S(X), 48G(X), 49? Do you see the Awaiting server command on the calc screen? Make sure you are using the correct serial port settings (many computers have at least two and you need to select the correct one in the software). More info would be helpful. == I use WinXP pro in my home computer and sync without trouble. I didn't change any of the default I/O parameters: Port: Wire, Type: Kermit, Fmt: ASC, Xlat:Newl, Chk:3, Baud:9600, Parity:Note and no Overwrite. Make sure you have the latest version of the HP communications software: http://www.hpcalc.org/details.php?id=3713 When your software starts the screen should say: Trying to open COM1. That step should be completed fine (green checkmark next to it). If you have other use for COM1 (notably synching with a Palm Pilot) that may be the culprit. I understand that the next step, Connecting to the calculator is what fails, right? Make extra sure that COM1 is actually the serial port you're connecting the cable to. Even laptops can have COM1 and COM2, and a modem will usually be something like COM4 but you never know, so double check. Put the calc in server mode before even starting the software on the laptop. My suspicion is that COM1 is either busy or blocked by another application or else what you think is COM1 really isn't. My 0.02. FYI: there was a bad batch of HP49s which did not communicate with all PCs. I had one of those - it worked fine on certain PCs but not all. I sent it back to HP for an exchange. The next one worked fine, like a 48. This had to be one of the earlier group of 49s. I bought mine in the fall of whatever year they were first generally available. ==== > >> Ayway the HP 28/48/49 style is not as good in keystrokes as the old system. >> there is always a trade-off... >> PS: Is there yet another way to do it? > >Yes. > >[p/r] + 7 * [p/r] > >7 [enter] 2 [r/s] 3 [r/s] 4 [r/s] 5 [r/s] 6 [r/s] > >For a total of seventeen keystrokes... 10/10 for effort but [p/r] is two keystrokes[1] so that brings it up to 19 - the same as mine.

Now I have to admit that my memory is not as good as it used to be. I'm pretty sure that INTEGRAL (integral sign) on either the HP38 or HP48 you had to use a closing parenthesis. You don't have to on the HP39 or HP49. There are other cases like that.

I'm not sure what you mean by the 2 enter pushes, but I did not use the EQW for the algebraic mode, I actually switched it to algebraic mode :) It looks a lot different in that mode, a whole new world. I wasn't considering doing the factoring method because you can't do that with all polynominals. The POLYEVAL is a much better method for entering polynominals anyhow. ==== X > My niece, not quite middle-aged yet, seldom uses math for anything > more complicated than balancing her checkbook or calculating a > percentage.

X I once had to find a bug in a Cobol program, in year 1983 I guess, concerning of more than hundred numbers, which did not add up correctly. I first claimed memory for 1..126 (IIRC the #) leaving R0 as a counter. Then constructed a small storing program and immediately started to key in the numbers. When finished I coded a viewing program and viewed the results. As I have suspected, I have keyed in some incorrect numbers (four of them) and I quickly replaced them manually then viewed again, they were OK. Then I coded a simple adding loop and got the right answer. Hmmm... I could have never reliably keyed in 126 different numbers adding to a total that I could trust on without a calculator such as the HP 41CV that I had back then. more than hundred registers were needed and even some more for those simple programs. Well I have thus checked that there was no numerical problem, so back to Cobol: but everything was alright with a Cobol program: Read in some packed signed binaries and move to display field and add. Hmm.. What if I make an (unnecessary by the Cobol Handbook) extra mid-transfer to an unsigned binary (the numbers where all positive) and then to display-type field to add up? That solved the problem! My superior had hard time to believe that a new recruit, a rookie, could have found a Cobol bug in an IBM machine, but so it was! Oh - those early days.

I've upgraded my ROM (from 1.16 to 1.19-6) since then, maybe that did something. I actually used this as a point for why HP's are better than TI's. When you change the modes, they are global. They affect the entire calculator. As far as I know, the 49 does a fine job with approximating integrals. You will probably be a lot better off if you get Urroz's books though. These books will teach you how to program your calculator. My Diff Eq professor made the final exam entirely about numerical methods. He suggested that we program our calculators to use the four numerical methods that we were covering. He told us that if we learned to program our calculators to do this for us, we could finish the test in 20 minutes, and get 100% on the test. I programmed my 49 in UserRPL and was out of there in 15 minutes, and got 110% on the test. Mine was the only perfect score. I was able to do this easily in UserRPL, once I learned how unbelievably easy it was. You just give the calculator the same commands you would normally give it whne you are performing the calculations. I was also able to help people do this on their TI's (I never truly loved my HP until I programmed a TI). The TI's programming language worked a lot like C++, which was fortunate (but it still wasn't UserRPL). I believe that the TI-83 works more like basic, which is a pain. Visit this newsgroup often. The people here are very helpful. Also, you can with a 49, so I understand how difficult getting calculator help can be. BTW: The TI-83 isn't all bad, it definitely has a better matrix editor than the 89 does. If you're an engineering student, that will be very important because you will be solving a lot of systems of linear equations. The 49 beats any TI on equation solvers though. --CS ==== > I actually used this as a point for why HP's are better than TI's. When you > change the modes, they are global.

On the ti-89 you just type in the equations and tell it which variable to solve for and it does. The 49 cannot do this. ==== 49 starts doing strange things. I have noticed that some of the modes seem to change unexpectedly. I've got Urroz's first book for the 49, so I guess it's time for the second one. I will also brush up on my UserRPL. My backup calculator is an HP48 (which I have the manuals for), so I'm not totally lost when it comes to the 49. But, I have noticed a few quirks and have gotten some unexpected (but not algebraically wrong) answers on the 49. Fortunately, I use the CAS to check my answers rather than give them to me, so I can usually interpret the results back to a textbook answer. I really didn't hate the TI-83+. It was fairly good at what it did, it just didn't do enough. It was only $20-40(US) cheaper than my HP48G and HP49G, but it didn't come close to the functionality of either. I will admit that the TI83 was better at graphing. It was easier to setup and seemed to draw the graphs faster than my HPs. One day I might get hold of a TI89 and compare it to the HP49 first hand. ==== > > you will be solving a lot of systems of linear equations.

The 49 cannot do this. I usually put all the relevant EQuations in variables like 'Vol=W*H*L' 'VOL.EQ' STO 'Q=a*t^2+b*t' 'Q.EQ' STO and then combine them into a list: { VOL.EQ Q.EQ } 'EQ' STO which I store into the SOLVER reserved variable EQ then I start it by 30 MENU | Vol | W | H | L |EXPR=| NXEQ| I key in, say 5_yd 3_yd 2_yd 1_l (yes, liter) and press enter to see them in stack, then I press the keys | Vol | W | H | L | and finally [Left-Shift] |Vol| for the first solving . Then I change any of the measures in the box (in feet, this time) and solve for any other variable. ***Note: The initial 1_l for Vol was to let the solver know the unit I was using for that Volume solved. NOW! I challenge *ANY* TI calculator to do that out of the box!!!

I guess this has more to do with personal preference than anything. On the TI-83, I can open the matrix editor and create the augmented matrix, then put it in reduced row-echelon form. The TI-89 doesn't have a matrix editor. On the HP49, I can create a matrix and put it in rref directly from the stack. This is my preference since I hate using input forms (wastes processor time).

There is no doubt that you will find many fans in this newsgroup of the HP49 (I myself being a die-hard freak).

They are basically equivalent in terms of functionality and power. The TI-89 is indeed faster for typical operations one might encounter in school. Also, there's a nice circuit simulator available for the TI-89: http://www.paxm.org/symbulator/download/index.html As Ray Kremer would say, read this: http://tifaq.web1000.com/p2.htm#4.1 -- Bhuvanesh ==== You can download an hp49g emulator from www.hpcalc.org. Then you can try it out for yourself. I prefer the hp personally, but the TI has its good points. I've heard that the hp is faster then the ti, but even though people keep threatening to compare them, no one seems to have actually done it. I've seen the HP do things faster than the TI, and I've seen the HP do things slower than the TI. RPN is nice. I've seen a lot of TI users spend a significant amount of time counting parenthesis. Another thing that you might want to look at is the programs that are available for both machines. www.hpcalc.org is the best website for hp49 programs. Someone else here will know where to get good programs for the TI. I have been dissappointed by www.ticalc.org, so hopefully that's not the best place for TI programs. I'd say download an emulator for the TI-89, but TI won't let you. You need a ROM image taken form an actual calculator. On another note, they would prefer to see people buy programs from their company versus downloading free programs other people have written. They make this fairly obvious in their attitude towards TI programmers. But, this means that there are TI programs available that are supported by TI. As far as I know, hp doesn't sell programs for their calculators. They expect the users to program them. This is fine, because I don't think hp would have been able to come up with some of the programs the users have come up with (keyman, fontman, jytris, FEM49, etc...). In both cases, there are a lot of people writing programs. What are the people on campus using? Have you asked any of your engineering professors? I'm the only person at my school with an hp49. I was lost until I found this NG. Having a different calculator is cool when you're showing off, but it sucks when you need help. --CS ==== > I'd say download an emulator for the TI-89, but TI won't let you.

I've seen a lot of TI users spend a > significant amount of time counting parenthesis. How about the speed comparison between a 48gx and 49g? I used the TI89 for a couple years before I got an HP-48gx. The HP-48gx is nice but I prefer the TI89 in many cases simply because it types faster and displays faster. It just feels so fast overall compared to the 48gx even though the 48gx often computes faster. I dont mean to get this OT with 48vs49 instead of TIvsHP but it may help him to know how fast the UI of the HP49g is. > Another thing that you might want to look at is the programs that are available > for both machines. www.hpcalc.org is the best website for hp49 programs. > Someone else here will know where to get good programs for the TI.

Thats not entirly true. You can use the .89u file freely downloadable from TI's website. The site only has the latest OS version, 2.08, which I certainly do not recommend but TI will send you the OS file > On another note, they would prefer > to see people buy programs from their company versus downloading free programs > other people have written. They make this fairly obvious in their attitude > towards TI programmers. What makes you say this? All of the programs I have seen for sell are in FLASH APP format. TI is developing and has released functional betas of their FLASH Studio. Perhaps it is the fact that you must submit your code to them for compilation and you only get 2 builds. I have never heard of anyone being rejected, do you think they would reject something if it was too similar to one of the products they were selling? > > But, this means that there are TI programs available that are supported by TI. > As far as I know, hp doesn't sell programs for their calculators.

Something about some guy who promoted TI regularly, and got screwed for leaking unimportant information that he shouldn't have.

That thread, among other things, have left me feeling really bad about Texas Instruments in general.

They are much too large and full of crap by people playing with thier busiest authors profile. 98% of the basic software feels like it is written by kiddies. The only basic programs that I have downloaded, I've gotten from either Roberto's site (http://www.paxm.org/symbulator) or Bhuvanesh's site. The authors of the software available as these two places are much more professional. Contrast that to hpcalc.org, where you don't have software written by 14 year olds. Not that I have anything against 14 year olds. -Samuel S, The one and only Cheerio http://www.calvin.edu/~sstear70/ ==== > X > > Thats not entirly true.

I like 1.05 the most since I had very few problems getting things to run. With 2.05 you have to patch things and some of the programs that worked fine with 1.05 crashed on 2.05. However, the archive is about 2x bigger on 2.05 and it supports FLASH APPs, so yes I would recommend 2.05. ==== >The site only has the latest OS version, 2.08, >which I certainly do not recommend. What's wrong with 2.08 ??????? I just downloaded it..... so I would like to know !!! ==== I have nothing against BASIC programs but I ussually look for ASM programs if I have the choice. Most of the BASIC programs I use I have written. I think BASIC is better suited for when you need to write a program quickly and you dont have access to a computer. As you mentioned, the fact that anyone can put anything they want in the ticalc archives leads to such contributions as This is my first game, please bear with me, its just a blob that moves across the screen. When you wade through all of that stuff you can find some pretty nice software. I have heard in several places that you are only permitted 2 builds per project. I will try to confirm this on the TIFS support board. Many programs require the hw2patch if you have a hardware version 2 calc and use a 2.xx AMS. The hw2patch has not yet been upgraded to be compatible with AMS 2.08 so many ASM programs will not work. As I mentioned before I like 1.05 because no patching is required. With the new AMS you get a clock, date, some new trig functions, and an application desktop. All of this takes up about 120k of your archive space. Its simply not worth it when you consider that the application desktop does not support ASM or BASIC programs, only FLASH APPS. Also, you can have a clock using a third party TSR that takes up only 1k of RAM. You have to ask yourself, are 6 trig functions and a picture menu really worth 1/6 of my storage space? ==== Evidently you didn't do a newsgroup search about this subject. Wars have been started on this TI vs HP topic. As a fellow student I will give you this advice - A calculator is just a calculator it won't make or break you. I do agree with what some of the others here have said - Give both of them a test drive, try them out, download the emulators, and see which one you like best. Both are excellent calculators. Where the 89 seems to look better and work faster (and is some ways it is), the 49 can be personalized more to suit your needs. There are plenty won't go into detail. That being said, the TI has one big advantage. TI still supports the TI89, where the HP49 seemed to have been dropped by HP like a hot potato. I do not own the TI89, but from what I've read the documentation is pretty good. Whereas, the documentation for the 49 is total crap. If I wasn't a previous owner of HP calcs (HP48G in particular) I would have been totally lost with the 49. To take advantage of the real power of the 49G you have to read this newsgroup and download documents from sites like hpcalc.org. And while these people that support this forum provide excellent information, It's a pain in the ass to have to go online for a question that should be answered in the documentation. Don't get me wrong I love my 49 to death, but If I didn't have any previous experience with HP calculators I would not own a HP49. I would either 1) Buy one the expandable calcs in the HP48G series 2) Buy a TI89 3) or wait for HP to redeem itself with a new professional line of calculators.

PLease I need your help desesperadtly. It sure sounds like the defective capacitor problem to me. It's hard to believe that HP support doesn't have any record of this problem. For your situation I recommend the following (admittedly drastic) procedure. First off, installing fresh batteries can't hurt. To make sure that it isn't an installed library causing the problem, hold down the backspace key while warmstarting to keep any libraries from being attached. If you do an [ON]&[F3] warmstart, pressing the backspace key in time might be tricky, so instead, get to the Tests display by pressing [ON]&[F4] together. Now hold down backspace and press [Q] (Reboot) to do a warmstart, and release the backspace key after it's back to a normal display. You'll get a DROP Error: Too Few Arguments from having the backspace key still down when it starts, but that's no big deal. If it works ok now, then you have a bad library and it's just a matter of attaching them one at a time until you find it. If it's an intermittent problem, it may well be difficult to tell whether you still have a problem or not. In that case, you may want to make sure that all libraries are available on your PC, and then use the filer to PURGE them all from the calculator. To make it easier to find all of the libraries on the PC, you may want to use the filer to SEND them all to a common directory on the PC before purging them. If you still have a problem, then ARCHIVE your home directory to your PC, and also make sure that you have copies of anything from your ports available on the PC. You may want to use the filer to SEND copies of anything from the ports to a common directory on your PC. Then do a memory clear. Use the filer to PURGE anything still remaining in the ports. Make sure that you have fresh batteries in the calculator. Then start the flash upgrade procedure (use revision 1.18, because HP may well refuse to support a calculator with a beta ROM installed), but erase bank 0 and banks 8 through 15 (actually, it wouldn't hurt to erase all banks) before doing the Download System. Finally, do another memory clear to remove any 'CASDIR' or CAS variables that were re-installed after the first memory clear (some of the CAS variables will be re-installed this time too). This will ensure that you have a really clean 49G, with nothing but the operating system installed. Of course, once you have a working calculator, upgrade it to 1.19-6, download and install everything that you want in your ports, and download and RESTORE your archived home directory. If you still have a problem, contact HP support again, and if they still suggest resetting the calculator, explain that you've already tried that and it still doesn't work and you're extremely unhappy. Of course, this assumes that you haven't damaged your 49G by spilling something on it or anything else that would void any warranty. I can understand HP not wanting to give you a free replacement in that case. -- James ==== Please tell me what is te seria number of your calc. I have a lot of S/N. (CN...) of many calc with the capacitor's problem if I know what is your S/N maybe that I can help you. JoGa > I have written a compalin to HP of USA.

PLease I need your help desesperadtly. If your calculator just resets from time to time then they are right : this is not a capacitor issue. You probably installed some buggy external software that are corrupting the memory and make it crashes often If your problem was a capacitor problem then you wouldn't be able to turn your calculator on after you had changed the batteries. So based on your description, I'm afraid that HP in this case is right and there's nothing wrong with your calculator. If your calculator is under warranty and doesn't turn on just send it back with the following text: Problem description: -Calculator under warranty, calculator refuses to start after I changed the batteries. ==== All this test you mention, Hp of Argentina has already done it, They want to charge me for u$d 130.- for the replacement, what i think itÇs a robbery. I will be waiting for your answer.

Indeed, so you have to probe the socket for data. You can do it with Usinagaz, and Thomas Rast did it well. I'd also say that telnet requires it as well...

I'm no fan of the 49 myself, but many of the 49 experts here are among the most experienced and knowledgeable of the 48 users and programmers. If all the 49'ers head off someplace else, we'll lose some of the best of the 48'ers.

PCs and palm-tops/PDAs lack a lot of instant functionality and keypad ergonomics that only compact calculators have. For professionals working in mobile environments (outdoors, labs, construction sites etc..) HP had produced the ideal suite of calculators to enable simple and moderately complex numerical calculations to be made almost instantly. The current evolution of mobile technologies towards gimmickry and useless add-ons is unfortunate. If a survey were ever done on the total number of HP calculators used by engineers/surveyors/technicians around the world it would be certainly more than thousands - Maybe tens or hundereds of thousands. Why lug around a high power consumption Windows device that takes several seconds to boot, just to compute the area of a football field, or a volume of fill ? While there is still a real physical world, there is a need for devices to do these calculations on the fly. That's unless somebody comes up with a virtual calculator for the virtual world. For Pete's sake don't offer HP any discouragement to continue to develop RPN/RPL programmable calculators. They are vital !!! Richard ==== I thought it would be cool if I could use the HP-49 keyboard (once you get used to it it ain't that bad) and functions, and the computer's screen and processing speed. I'm not talking about making my calculator part of the computer, just making them talk to each other a little easier. I like this idea because I know the keyboard so well, and I have yet to find another math program that will do what the HP-49 does, as well as it does. I go to the computer to do math when I can't see enough numbers on my little LCD. Othewise, I use the calculator. I will actually sit in front of my computer, and check what it's doing (to make sure it's right) with the calculator. If it was on the computer, I could view way more lines in my stack. I guess this could be done with a good emulator though; maybe one that allows me to configure my keyboard. Creating/storing objects and programs would be easier too. Just a thought. --CS ==== e9de8ebc.0304151655.7b86af36@posting.google.com, Richard > I disagree with this perception entirely.

I never said that I didn't believe a pocket calculator could do a better job than most PDA. Quite the opposite really. But what I believe and prefer (and so are your preferences) are irrelevant for the market place. The fact is that PDAs provides a higher source of revenue than calculators and that's why HP left the market and why most new calculators will look more and more like a PDA (that's IF any brands will even bother to make another very high-end calculator). ==== > But what I believe and prefer (and so are your preferences) are irrelevant > for the market place.

Yeah, the Casio ClassPad 300 is sort of a hybrid. I looks like a PDA but it has the functionality of a calculator and is programmable in a very nice dialect of BASIC. You mention that HP has left the market while others here talk of an upcoming new calculator entry. Is HP really out of the business? If so, that would be a shame. Not only would that mean the death of RPN but other makers would have no incentive to improve their calculator lines. I remember the great marketing wars of the '70s when HP, TI, Sinclair, Casio, Sharp, and a bunch of smaller firms would print comparison charts showing theirs was best. Ahh, those were the days.... 8-) Tom Lake ==== > > e9de8ebc.0304151655.7b86af36@posting.google.com, Richard > > I disagree with this perception entirely.

What can be said for niche markets though ? Clearly, retail costs of high end calculators increase exponentially with respect to production quota. There is a dedicated niche market for such calculators outside the college / educational area. I think the main reason for the decline in the programmable RPN HP calculator is that the educational sector has prevented their use in their institutions. Another reason, is that advances in calculator hardware have not kept in step with computing hardware and mobile technologies elsewhere. Features and appearance have overtaken functionality and durability as marketing principles. It's OK to get a cheap and nasty $5 calculator for day to day tasks, but to have to spend $100 to go the next level up in calculating power is ridiculous !! (OK, that's an exaggeration, but it's where we're heading). In a world driven by appearances and marketing blurb, the marketeers dictate what they think consumers want, not what they need. Those of us who still have any independence don't have much input in what goes on in technology development. We fill in all these product surveys, questionnaires etc.. etc.. but for what purpose ?? The fact of the matter is, why are professional people (and not necessarily HP fans ) forking out hundreds of bucks for second hand HP41s, HP42s, and even HP32s ??? There must be a huge market out there, though not as large as the educational one, but large enough to be viable, to supply the demand.

Great Great I think so we will wait for it. JoGa ==== I'm presently taking a course that is very strongly geared towards the TI-83. I would nonetheless like to try doing it on my HP48. One of the problems I have come up with is finding the vertexes of parabolas. Using the equation '-2x^2-3x+9', they tell me to use the max/min functions of my TI to find the vertex. Using the EXTR function of my HP48, I get the answer: (10.152739778, (angle)94.236394799). Using a TI's MAX function, I get: (-.7500004, 10.125). The latter is the correct answer. What am I doing wrong / how can I get the latter type of answer from my HP? Steve. ==== Steve, Your calc is in polar mode. Just enter RECT to set the rectangular coordinate mode.

And I thought you could too (respectfully, of course). I did not see the HP49 mentioned anywhere in your link. I know HP still makes calculators. However, since the HP49 they haven't made anything worth buying IMHO. When they do I will be one of the first people in line to buy one. And I go back to my statement in the previous post. A CALCULATOR is just a DUMB OLD CALCULATOR! Choosing one over the other is not some life altering event. I saw my first graphing calculator in 1989 in AP Calculus in high school (I didn't start college until recently, but that's irrelevant to the story). I believe it was a Casio. Anyway, one of the students in my class got it and I thought it was the coolest thing. But, it didn't help him much. He got a C in the class and failed the AP exam. I got a B in the class and passed the AP exam with a regular scientific calc. NO CALCULATOR will MAKE you into an A student or a top notch engineer. Its only a TOOL, and when it has as many bells and whistles as TI89 and HP49 it almost becomes a TOY. This time around I plan on making an A in Calculus, and I could do that using a SLIDE RULE if I had to.The Best Calculator will never take the place of the human brain (not in my lifetime I hope). I would like to preach some more but I have to go over the Calculus Marathon that I just a good Day!

TI-BASIC is intepretted but ASM is machine language. This makes ASM immensly faster and allows you to do many more things. When I first got my TI89 I made a pong game in TI-BASIC. It was barely playable. The ball took several seconds to move across the screen. With C on the other hand games have been written in 4 level gray scale that are similar to and as *fast* as Wolfenstein 3D. I once had 20+ units on screen in a real time stategy game modeled after command and conquer and there was no lag. This includes full enemy AI. I know this is useless when you need something that finds the missing leg of a triangle but if you get any more complicated I would recommend an ASM program. > I have heard in several places that you are only permitted 2 builds > per project.

And until 15 years later it was stolen from my baggage overseas. That sliderule was for mechanical engineers and handled every mechanical engineering job, it even had a Log Trig Scale. It was the best sliderule, as far as I was concerned, a bamboo material that was bound by a plastic or enamel material on the outside and where the scales were found. The cursor assembly was of a very good design, Hemmi placing a good and thoughtful design on it. The cursor glass was made of real glass. Everything on the sliderule was the Real McCoy, no frills. About 7 years ago I was able to purchase a brand-new Hemmi 259D from a friendly Hemmi Associate in Japan. He sold me the authentic sliderule, the owner's manual, and the brown leather case - all new. So right now I have recovered something of worth that I lost long ago. But for a sliderule to compete with an electronic calculator is a mismatch. However if you have plenty of time in your work it is still a good thing to be using a sliderule.

They answer saying: We do not have any records of the problem you are describing (capacitor). Sometimes a calculator locks up or will not respond correctly. The calculator might require a reset for a variety of reasons. Performing a soft reset will not affect the memory on the calculator. However, all other types of resetting will erase the memory and restore the calculator's defaults.

Can't do it. The CAS isn't integrated into the rest of the calc. Try inputting various functions from the Catalog when entering an equation into the Equation Solver. Can't. The Catalog isn't active, OPTN gives SOME choices but not many. In programming, you're limited to single letter variable names, and list names all start with LIST. There are a number of other annoyances as well. The ClassPad seems to handle all my concerns with the AFX. Tom Lake ==== Greetings. [Edited for size] >I have an AlgFX 2.0+ and a TI-89 and almost always use the 89. Try getting >imaginary roots of an equation from the MAT screen on an AFX! First of all, although the RUN mode of later model Casio calculators has subsumed the Matrix editor (MAT mode), IMHO it is still called the RUN or RUN-MAT mode, not the MAT mode. Pedantics aside, I don't think it's fair to fault the Algebra FX's CAS mode for not being able to work in RUN (aka RUN-MAT, or, if you insist, MAT) mode, just as I don't think it's fair to fault the TI-92+'s CAS mode for not working in Var-Link mode. I've also heard that the HP-4x calculators do very poorly when in the off mode, yet I will not hold this point against them either. For who knows what reason, Casio calculators feature several distinct operating modes. If you like this arrangement (as I sort of), you can defend it by point out that it gives you two or three calculators in one package, for one price. For example, I was recently using my FX's CAS mode to work on one problem, when I wanted to work on another. I switched to its RUN mode (i.e. non-CAS scientific calculator mode), did my calculation(s), and then switched back to the CAS mode. Absolutely everything was as I had left it. Swell, don't you think? Of course, I can see how the variety of modes might pose difficulties for those utterly without any deductive reasoning abilities, and for those who simply cannot RT(F)M (which is included free with the Casio calculators). >In programming, you're limited to single letter variable names,... [Algebra FX] And two Greek letters, for a total of 28. Further, functions, written in traditional syntax (i.e. f(x)), are only slightly supported in Graph mode. >... and list names all start with LIST. For a guy who can't keep track of what mode his calculator is in, I'd think you'd appreciate the hint. BTW, in CAS or Algebra modes lists, matrices, and vectors are all assigned to single letter variables, just like scaler or complex quantities, and without the LIST or MAT prefix. (FYI: Algebra mode is a separate CAS mode. It is designed (IMHO) to be a canvas for manual equation tinkering, rather than assisting or supplanting it as CAS does. Algebra mode lacks auto-simplification of answers, and supports an expurgated set of commands.) >There are a number of other annoyances as >well.

No one would expect it to calculate anything in that mode and the Catalog isn't needed. The Catalog would be VERY useful in CAS or Equation modes but it isn't available. My HP does much better in Off mode than my AFX does in MAT mode! Since the TI-89 has no problem at all using CAS in any *CALCULATION* mode, it's not unreasonable to expect the Casio to do the same. In fact, as I stated, Casio admitted that limitation of the AFX and has fixed it in the ClassPad. > > For who knows what reason, Casio calculators feature several > distinct operating modes.

The HPs and TIs are so far out in front of this one thing in defense of the Casio AFX, though. It's a DOS machine and can run MS-DOS programs. I've written programs in 80286 assembler, GW-BASIC, C and even a FORTRAN and a COBOL program that all run on the Casio. It's easy to program for. Tom Lake ==== Regarding your recent post: My shots are not cheap; I spend a great deal of time and effort on them. I (continue to) disagree that the failure of a command to work where it is not meant to work represents a deficiency. Look at these poor HP calculator users; several bug fixes ago, they would have been happy if their calculator's (de mortius nil nisi bonum) functions functioned anywhere, at any time! You do raise -- or at least skirt around -- a valid point: although the FX series of calculators are flash upgradable, Casio doesn't seem to have any intention of releasing any flash upgrades (although they have released a few flash applications). While the Algebra FX 2.0+ is apparently physically identical to the FX 2.0 (and FX 1.0?), the only way to upgrade is to replace the entire calculator. They also seem to have no intention of releasing anything close to the low-level programming information available for the TIs or HPs, even though one could not possibly ask for a more fertile programming field than that provided by the DOS-turbo-XT-computer-pretending-to-be-a-calculator Algebra FX. And, since you appear to have some knowledge of low-level Algebra FX programming, shouldn't you be off writing an FAQ rather than bantering with me? AFAIK, the only Algebra FX programming FAQ that exists is in French!

X de mortius = death? nil nisi bonum = does not do good (get us a bonus) Please translate...

I'm in the same situation and I use the free news.cis.dfn.de news server. It's free but you'll have to register ; takes about 2 days.
