B229 I have had a 49g+ for quite some time now and have had very few problems with it untill now. It froze up the other day so I took the batteries out to reset it. After replacing the batteries my calculator would no longer turn on. I left the batteries out for 24 hrs plus, to see if that would work and I have also replaced the memory backup battery. No luck as of yet. Has anyone had this problem, if so, do you have suggestions? If there is no hope for such a problem, will HP replace my calculator, if so Who should I contact. Any information would be very much appriciated. Jonhorner It sounds as if one of the keys is stuck down. When this happens, the calc locks up completely, and the display doesn't work. You can't tell which key it is becuase it's something behind the key that gets stuck, not the key itself. This is what happened to my first 49g+. The best advice I can give is to press and release ON, then press every key a few times (forcefully). If you're lucky (I wasn't), your calc will work and as long as you don't press the bad key, you can back up your flash memory and anything else you need to. Then call 1-800-HP-INVENT and get it replaced. Hope that's helpful. Bob X-RFC2646: Format=Flowed; Original Did you try the hard reset (back of the calc)?

[VPN] negative distance makes perfect sense in certain occasions, it depends on how you think about it. the same way you have negative angles cheers expensive As it's been stated many times here, the magority of buyers (HP48) buy it to use it rather than for collections.

Question 2: The programm is called MITTEL and it is stored in the folder HOME Allg. I want to acces the programm via one key and I want to use the KEYMAN by Wolfgang Rautenberg. How can I execute the program without changing the actual path. F.e.: I am in the folder HOME xxx yyy and the prog MITTEL in its folder HOME Allg should be executed, WITHOUT changing the path to HOME xxx yyy. Christian B. P.S.: I love this calc...except the missing kestrokes. posting-account=d8X8zw0AAAB_Eo2ldj3HF5DzN42pN3GY Well there are many ways to do something like this. I will jsut show you two general strategies for writing calculation programs. 1st: Instead of storing a value and then deleting it afterwords, a This will create a temporary variable that is then deleted automatically. It is also much faster. This can also be used with symbolics. To see how this works, type 'F(X,Y)=X*Y' and push DEF 2nd: A stack calculatiuon program. You could think of this as a script to automate your calculations. Now instead of saving the DEPTH, I can just use commands to get the info I need, save the info, make copies of it, order it, etc. Now you might be tempted to think that the first one is smaller, but the second is actually much smaller. Each item turns into a 2.5 byte command. The other has some hidden ones that take up more space. Note that these are very unoptomized programs and will you will most likely get some nice ones shortly, I just wanted to point out different strategies. An interesting feature few new users know about (and it messes them up on occasion) is that when you do a RCL or EVAL on an 'ID', if the item isn;t found in the current directory, it will keep searching in the upper one until it finds it, or return it unevaluated. So if you kept that program stored in HOME, no matter where you are in the directories, it will get to it and run it from anywhere as long as no other item with the same name is found. You could save and then restore the current path. The other option is to save the program in your actuall key assignments. That is generally not a good idea for larger programs, but small ones aren't a problem. I personally would recommend making a library of you own to install. I did this whenever I needed a program to be availible anywhere in the calculator. I made a My Functions library. Then your commands can be run anywhere and will show up in the CAT like they were a built in function. The calculator has a program built-in to make libraries. Wolfgang has a small utility named OT49 that, among other usefull thigns, makes a nice easy way to inteface with this command. You might want to look at that. Have fun and keep programming! TW thx Tim for this answer.. The more I get to know the calc, the more I like it... I will try to make my own lib now... way Waouw... that's not a light solution !! Daniel: maybe just install Open-Fire in Port0 :)) I agree it is like -hard core solution ...hehe :-) Daniel, stop what you're doing and try Lilian's solution first :-) (i assumed you tired other ports) manjo posting-account=uEneJgwAAACq_Zl4LvcXzJQivcElZXhl IMHO: I think the Qonos project is worthy of support. Firstly I think the guys doing it want to achieve a quality calculator type product (even if it costs more), which I think now is unlikely to come from HP (in terms of physical manufacture like the HP48sx, keyboard etc) - given shift in HP corporate culture and marketing focus. This product will also be fast. An effort is being made to not disappoint on this aspect. If my understanding is correct Quonos may incorporate datalogging capacity - a feature I have raised a few years back in this forum as a good add on for a new generation of calculators. I am surprised HP have not added such capacity to date given HP calcs already have data handling, statistical functions, graphing etc. I am certainly pleased the Quonos people have taken up this idea. While datalogging may not be of much use to mathematicians, I think it will be of considerable convenience and use to a lot of other users. Makes the unit a much more complete tool box for tackling many applied tasks. As for a small portable device with keyboard (re the laptop argument), having had my HP48sx die recently, I resorted to a el cheap non RPN calculator, then tried to do simple calculations using the laptop calculator, then using the more nifty text based mathpad (another innovative idea), .... well I have been refreshed in that saying .. you appreciate what you have the most when you no longer have it! RPN calculator with stack, programability, good keys .... such a time saving useful device. For what such comment is worth. Cameron Downunder. take the extra time to get it right.

Volker -- Besides, i'm of the opinon, that TCPA has to be stopped I think that there's a place for both approaches and my concern is that the passion of the arguements will result in one approach dominating when it should really be a mixture of the two. There's certainly a place for expecting some students to be able to solve problems using no artificial means but, realistically, that's not how it usually happens in the real world of engineers and technicians. It's critical that students learn how to effectively use the tools that are out there. The problem we educators have is that the complexity of the tools is fast becoming overwhelming. For example, how do you guarantee the security of an examination when even the most modest PDA these days has communication that allows students to talk to people outside the examination room? Where do you draw the line when the software is becoming so good that it will do literally any mathematical operations, apparently without any need for knowledge on the part of the student. The question becomes what knowledge do we teach? And it's NOT an easy question to answer. The knee-jerk solutions tend to be too simplistic. Personally I don't have any good answers and I'm hoping that the research being done will supply some. Of course, i see those problems too. But i think that learning for students should have a touch of real life like it is out of the classroom / lecture-hall. And out there nobody is expecting that you e.g now 41 formulars for economic index numbers (Return of Invenstment, Banker's rule and further more) by memory. But what they expect is, that you know what those numbers mean and what the tell you. So, where is the sense in learning those formulas by heart instead of using a formula-book? Even during my last years in school in any physics-exam we where not only allowed to use our formula-books but also to use our programmable calcs....

Rather than talk about the software, this post deals with a more better hardware design. Incidently, these ideas are not new but rather a re-application of some of the genius shown in the -41 series. See what you think of the following... The calculator should have a raised ridge around the perimeter of the calculator body. This serves two purposes. First, it provides a means to attach user defined key templates/overlays on the keyboard. The 49 calcs allow for user defined keys but how is a guy supposed to remember the key assignments without an overlay which has them labeled? Secondly, the keyboard and display would be better protected if there was a raised edge. It would be less likely to get the display scratched and fewer accidental power-ups due to pressure on the keys when carrying in ones pocket. As you know, the 49G at least had a slide on cover for protection which was excluded for the 49G+ -- seems like the hardware design is going backwards in some respects. Rather than have the IR and USB ports integral to the calculator, they should be plug-in modules. There would be endless possibilities if the 49 hardware had an open architecture port. This also has some positive marketing aspects too. The base calculator could be sold cheaper as it would exclude the accessories. Depending on the user's needs, additional modules could be purchased. If you need an IR interface, buy the plug-in IR module. By having the IR module a separate item it could be designed to have a longer range (like it should) yet could be removed for taking exams at school. That way the 49 could be used during tests without the risk of students IR'ing each other in the class room. If you need a USB interface, buy the plug-in USB module. If you need an RS232 interface, buy the plug-in RS232 module. If you need an analog and/or discrete I/O interface, buy that module. If you need a rechargeable battery pack, used for extended operation plus comes with a charger, buy that for the calculator. module. If you need a GPS receiver, buy the GPS module. If you need a cell phone transceiver, buy the Cell Phone module. What about 3rd party application and/or development modules? Not that any of this stuff really exists, but do you see where I'm going with this idea? And last but certainly not least, the keyboard would have molded keys that never miss a keypress and have the tactile feedback similar to the -41 or -48! Comments from any of the hardware guru's out there? Gary No one would mistake me for a hardware guru, but I think your ideas are excellent. They would go a long way toward undoing some of the damage done in the transition from the 41 family to the 48 series. -- Wayne Brown (HPCC #1104) | When your tail's in a crack, you improvise fwbrown@bellsouth.net | if you're good enough. Otherwise you give | your pelt to the trapper. e^(i*pi) = -1 -- Euler | -- John Myers Myers, Silverlock X-RFC2646: Format=Flowed; Original As you know, HP used to sell Overlay sheets for the HP48G (original) serie. I can not communicate the number of overlay kits that HP sold (being a HP employee), but I can tell you that in 3 years, selling HP calculators in a retail store where I have sold over 3000 HP48S, SX, G and GX, I have sold around 10 overlay. This means that overlay are used by way less than 0.3% of the users (I say way less because our store was more of an advanced store than a all public store). Truth is, most users do not re-assigned keys, and user who do usually only reassinged 1 or 2 keys and to not need overlay. Now, do not get me wrong, overlay are good things (I myself have one on my HP49GX), but raising the side of the keyboard, adding 2mm = 10% height to the calculator (and no, we can not recess the keyboard), would make it bigger for the 99% other (mostly students) who already have quite a large bag. In addition to this, not having raised edges does not mean that you can not put overlay! you can have a tack on overlay that adhere to the plastic case (similar to the plastic used to protect the screen of new electronic devices). I have been sending the exact dimentions of the key/keyboard to all the peoples who showed an interest in making overlay (the 2 of them)... A well padded leather carying pouch is provided in order to protect the unit, this certainly does follow up the old HP tradition that the HP49G dropped by going with a hard slide on cover (I can dig up list of emails commenting on this)... This seems to me like a good step forward... actually, this is not true. Providing multi function IO ports would be more expensive. the IrDA Leds cost less than $1 in a basic electronic store, and the volume cost are even lower. Creating a robust plug in module system, with support for software Drivers, port protectors for when the modules are not there would increase the cost of the unit, not lower it, and make the R&D much more expensive. Provided the other person also has the long range IR module... let us face it, verry few peoples buy accessories (saddly enough) , that is why, for example, it is more cost effective to have the connectivity kit being part of the package than to sell it separately). an IR module would cost around $25 retail price. provided that the unit cost for the calcualtor would not decrease (see above), how many peoples do you think would buy the IR module? not enough for HP to make any profits... now, that is an advantage... but limiting the IR range to 10cm solves that problem, so this is the route that we choose. $25 again if you want to buy in retail? adding the USB to the calculator just cost the cost of the connector because there is full USB support in the CPU (<0.50 in any electronic store, even cheaper in volume). $25 again if you want to buy in retail? adding the USB to the calculator just cost the cost of the connector because there is full USB support in the CPU (<0.50 in any electronic store, even cheaper in volume). yep, that is called a datalogger and cost around $300. Firmware used to make one for HP. They closed their door because they were not selling much of them. Vernier makes some for TI calcualtors and sells 1 datalogger for every 5000 calcaultor sold... Again, I have nothing against the idea (I am an enginer, I love gadgets, I even have a logic dart at my desk)... well, nothing stops you from buying a battery charger and a set of rechargable batteries... nope, this is a software limitation. the saturn CPU can not address more and countless issues comming from the fact that the ROM is bank switch. and connect it through the RS232 on the HP48Gii... you can do that... the GPS will cost you more than the calcualtor, but you can... connect your cell phone through RS232, that works too... and then, what will you do with it? on flash rom through the SD card slot?

But I need to tell you though, the list I provided is what I could use in an HP calculator. Recognizing that things wouldn't be cheap is understood. If HP is going to advertise calculators for professionals then the product should meet the needs of the professional. This usually comes at a price. There are many, many applications for a high powered calculator. I used to take my -41CV on helicopter flight tests. The hardware design was crucial to being able to use the machine in that environment. And equally important was the ability to use peripherals/accessories back in the hotel room after the flights. I don't feel that I have the same capabiity today with the current offering of HP calcs. The software functionality is superior but the hardware design is lacking IMHO. If you build it he will come. Gary posting-account=d3pZ8wwAAAAaSPTWKXXC3YhL1q7T1zbD Regarding the RS232 ports: Is this really true? Will an outboard GPS receiver or Cell Phone Transceiver provide power to the crippled RS232 port on the 48gII? I do not believe so. It will work with the (older) HP48 which did not rely on external power to provide a true RS232 port. I DO agree that for the mininal incremental cost, it makes sense to build-in standard IR and RS232 ports and add on from there. I do NOT believe that the current units provide this utility. Tomcee ps: Also keep in mind that RS232 requires virtually no software drivers as USB does. pps: I believe a (memory expanded) HP42s (physical) package, RPL and two-way-IR and RS232 built in is very close to ideal. the means 49 remember serie. a HP in a sold 0.3% of store only on my height to it large can not plastic electronic key/keyboard to them)... there keys seems the HP49G emails they the positive as it be more volume support there much the range face for part unit cost do you profits...

Thus assembling a FORTH for a target CPU is trivial for the FORTH part , the hard work is only learning the CPU inst set !! It is zero FORTH assembler work , only learning the traget inst set !! It has none of the crap of conventional assemblers , after all it KILLED assemblers !! posting-account=fgGaTw0AAAD45Fx2_7bZCc6hcNf--wQo Here's the problem : Boy, that sure is a silly claim! As probably the ONLY one reading this news group, who actually has an original legal right (from Forth Inc.) to use the name Forth on a product (my Apple ][ Forth system published and marketed in 1979 !!!), I have to say that makes no sense. --------------------------------------- Now do you see the problem ? Now lets FIX the problem !! This idiot can only think of ways to stop creators , excuses why we CAN'T do this or that . Too many people has reasons why we CAN'T do it , after all we must obey the law , or some other flimsy reason . . All of our law is harming America , copyrights , patents , Taxation , crony H.P.'s , A.A. You are a sell out .. posting-account=fgGaTw0AAAD45Fx2_7bZCc6hcNf--wQo a target Forth in Forth . You need to do less writting and more study . Forth is written in Forth not assembler . No tedious assembler . Got that ? ----------------------------------------- I was going to write several paragraphs about why you are incorrect, posting-account=fgGaTw0AAAD45Fx2_7bZCc6hcNf--wQo There is no such thing as a FORTH to C or vice versa cross compiler . You are fools !! FORTH is a solution to C , so no one will cross compile anything from C to FORTH !! The very reason you'd use Forth is for the stupid obtuse of C , so how would you learn enough about the way your C app works to CROSS ?!!! Think !!! *cough* http://www-personal.umich.edu/~williams/archive/forth/hatforth/hatforth.html http://www.compusmart.ab.ca/rc/Timbre/timbre.htm http://www.compusmart.ab.ca/rc/Timbre/CwithoutC.html http://portal.acm.org/citation.cfm?id=165628.165635 Etc. This is entertaining :-) G. posting-account=vi-M7A0AAADUqHaYtEVBSZ22QJJdWL54 I just bought a used HP 49g. While experimenting, I accidentally toggled the custom menu, but I don't want a custom menu. How can I revert back to the old, default menu? Daniel Ehrenberg : Hi Daniel, try the VAR - key Heiko posting-account=i3UCPg0AAAAwQSpCf7-v8Zxg-S-MJm3T Does anyone know if it is possible to copy the contents of the EEpro ROM for the HP-48GX to run on the HP-49G/G+ Steve posting-account=Kc05ZA0AAADq7YTEHoMU9Aer5AhqUt9P Is there an English-language website with screen shots of the English-language version? Hello I'm doing the following in complex rigorous mode, with RCLF { # 7280030E81914FF0h # 10h # 89810440A000048h # 0h } It seems the HP49G/G+ has problems handling complex ABS in integrals. For a minimal[1] example, enter the following integral in EQW: int_0^1 |t+i|^2 dt If you EVAL this on the HP, it returns (after simplification) i - 2/3 which is quite obviously wrong since the real integral of a real-valued function can never be complex. As a workaround, first use EVAL on the absolute value, which results in int_0^1 sqrt{t^2+1}^2 dt This readily EVALs to the correct 4/3. Note that ABS on the stack will automatically simplify (or complexify?) to the sqrt{Re(..)+Im(..)} form --- unless the HP deduces that the argument is real, e.g. through REALASSUME --- similiarly to the separate EVAL, which then integrates correctly. If you enter the integral in EQW, this step is skipped and the integral result will be wrong. Combining with which explains similiar problems with real ABS, I conclude that the 49G CAS is, unfortunately, not trustworthy if you integrate over absolute values. Thomas [1] For a truly minimal example, leave away the square; the results are similiar, but a lot hairier. -- If you want to reply by mail, substitute my first and last name for 'foo' and 'bar', respectively, and remove '.invalid'.

If you want weird, try using INTVX (VX=t) then substitute t=1 on the EVALed result and EVAL Now it's -1+i(2/3) rather than i-2/3 at 01:17 local time I need someone to verify this [VPN]
