2170 From In[46]:= abc Sorry. I ended up doing something completely different this weekend and got it to work. I went and bought a female DB9 connector and soldered wires to pins 1,2,3, and 5. I soldered the other end of the wires to wire wrap posts, then shoved them into the 4 pin side of the 10-4 pin adapter. It works. So I'm going to call HP parts (different from shopping village) and order part number F1633-66001 (part number for the 10-4 pin adapter). When I get it, I'll make what I rigged this weekend permanent, and I'll still have an adapter to use for 48's. Also, you can order 2mm headers from DigiKey. They are the most popular place to get parts amung us EEs here at USU.

So around that period of time in order to replace the screen it would take $100. I was wondering if anyone knows the current price on the screen replacements for these calcs. Or would I just be better off getting the 49G? What worries me is the incompatibilities with running 48G* programs on the 49G. Entrypoints etc. I heard that it was just binary only programs though. I did wonder if there could be some way to run a program that would interpret the 48G* binaries and point them to the correct entrypoints. (Maybe just wishful thinking?)

But if you can't an you know some HP48 hardware hacker, he may be interested in your smashed 48. So selling it to him for a few bucks ($20?) and getting a new hp48 may be another option... That is possible, but only system-RPL programs that use only supported entry points could be translated reliably. The problem is that many great system RPL programs use unsupported entry points, and there no insurance that those entry points even have an equivalent on the HP49. And even if some of them do have an equivalent, it will take quite some time for them to be found. Some ASM programs could also be converted, but, apart from the already mentionned pb with unsupported entry points, ASM programs often do tricky things with adresses for the sake of optimization (like partial register loading while accessing the system memory, or adress tables, or whatever). And tracking all those things is nearly an AI-complete problem. There is a precendent, 48S to 48G converters. They work sometimes. Share what you know.

Collect logarithms with LNCOLLECT. You get LN((COS(Y(X))+1)/(COS(Y(X))-1)). Select this term in the equation writer and replace cos with tan of the half argument with HALFTAN. The term is replaced by -LN(-TAN(Y(X)/2)^2). Your solution now is -LN(-TAN(Y(X)/2)^2)/2=SIN(X)+C0. This can be solved explicitly for Y(X). I don't know why the HP49 doesn't do this steps automatically. Perhaps some flag settings? But this story shows that no CAS can be perfect. The HP49 is a excellent tool but don't expect it to do miracles. Nothing replaces thinking (and math knowledge unfortunatelly ;-) ) Hope it helped. Greetings from Germany Nick Karagiaouroglou Share what you know.

Amazon.com and Borders both have it listed as out of print. Does anybody know of a source that still has it in stock? ---------------------------------------------------------------------- Sigh...looks as if the HP-49G, which includes many wonderful things, appears to have more bugs than prior HP graphic/symbolic calculators did. To be expected, I suppose. A rush to the market, knowledge that your mistakes can be fixed easily, creation by a team that knew the HP-48 well (more than almost anybody?) but did not have any in-depth history with earlier HP calculators of days gone by. Heck, some were in diapers at the time of the HP-65! All prior HP's had bugs... The HP-65 had some pointer bugs that could be exploited for some wonderful space games. Other bugs allowed for the creation of a pause feature, counters, etc. The HP-41 had some bugs (hooray!) that allowed the development of synthetic programming, which helped give birth to a true HP calculator hero, Dr. Bill Wickes. Dr. Wickes, perhaps more than anyone else, is responsible for the symbolic capable-HP calculators we have today. If it weren't for his leadership on the HP-28C, HP-28S, and HP-48SX, where would we be today? Some bugs have not been as pretty, but they were mostly minor annoyances. A spurious } symbol left on the stack (HP-28C), the incorrect SINE of 0.000001234 degrees (HP-41 (who on earth needed to do that anyway?)), etc. None of which compares to the HP-71 bug that would erase all of memory under certain conditions in calculator mode. Which brings me (finally) to the point of this retrospective: Where were the long-time HP calculator users in the beta test team? Quite a few of the bugs posted about the HP-49G are coming from a small group of people, most of which are OLD-TIMERS in the HP calculator world. Was Joe Horn a beta tester? No. Was Brian Walsh a beta tester? No. Was Richard Nelson? No More seriously...was Bill Wickes? Apparently not. Suggestion for next time... Put beta units in the hands of users who have experience LOOKING for bugs...it does take a certain mindset. Flash rom is nice and will surely fix many of this unruly bugs...but this machine would probably never have been released in its current state without this capability...it would have been tested better beforehand. Let's learn from this and test the next one better... Thoughts? Gene Wright http://members.aol.com/hpgene Share what you know. Learn what you don't. ---------------------------------------------------------------------- I agree with you on having more beta testers and those with long time HP experience help on the next machine. HP's letting a few whiz kids and a math professor, (mostly from France) design, build and test the whole thing is suprising. However, it ain't over till it's over... Let's see if the current team can make the Flash ROM update work. If the bug and manual updates get out quickly, this new machine may truly be the revolutionary step HP needs to really compete with TI. What I mean by that is not producing a machine to appeal *solely* to engineers, who are a rather small niche market. HP's new strategy to *also* appeal to students is correct. Wherever you go in America, TI's are easy to buy as loaf of bread. But you really have to go out of your way to buy an HP. HP's calculators need to be in every Walmart, Kmart, Target, etc... just like the TIs. And, once students learn about HP's quality, accuracy, and reliability, they'll buy HP again when they get to their respective careers later in life. diapers do small Share what you know.

I can't work on it anymore, it would mean ignore a full year of developmet. Unfortunately I can not release the source to 3.2 now but you can have an idea of many algorithms used by viewing the 3.024 source code. Bernard Parisse ---------------------------------------------------------------------- Will the HP49G accept units on other types than real numbers? It would be nice if one could use units on symbolics, and especially for me, it would be VERY nice to be able to use units on complex numbers. If it doesn't as of now, consider this a request for that functionality in \ a later Flash Update. ---------------------------------------------------------------------- This problem will never in real life be worth solving symbolically. MathCad 7.0 will spend around 12 minutes on the problem on a PIII 450, and then return with a Symbolic result too large - and I expect this error \ to have sprung from a mid-way result, rather than from the final form. When using large matrices, they will be numerical, and you will learn to use reductions and elimination of variables - and fast computers. Just my $0.02 ---------------------------------------------------------------------- I don't think so. Doing symbolic stuff by hand or with a CAS is really different. You have to learn what the CAS can solve and a bit how it works so that * you can check that the answer is correct * you can find a better way to formulate the problem for the CAS if he did not solve it. Let me take one example, suppose you want to integrate sqrt(tan(x)) on the 49. If you do sqrt(TAN(X)) INTVX it will return the integral unevaluated INT(sqrt(TAN(X)),X) But as a mathematician, you know that the change of var TAN(XT)=Y will transform it in a sqrt over a rational fraction. This can be integrated by the CAS. So do the substitution 'TAN(XT)=Y' SUBST and EVAL the result. I hope I have convinced you that it is useful to teach how the CAS work and what it can do. ---------------------------------------------------------------------- I'm trying to select easily a line in the MKeditor, and execute it, but I don't know how to make a kind of macro, to have less keystrockes than begin shift rarrow end next next shift stack next next (to come back at the first menu) I suppose it is the same in the new 49.

Seeing as you just moved from the TI to the HP, do you find the screen limiting, or has HP done a good enough job with the UI that it works well? Dave Baum p.s. For reference I am currently own a 48G that I really don't take full advantage of because of how cumbersome (and slow) the UI is. -- reply to: dbaum at enteract dot com ---------------------------------------------------------------------- I recently have moved from a TI86 to a 49G, and can't say I have even /thought/ about regreting it. The screen on the the 48/49 is slightly higher resolution than the TI86, and much less than the TI89, but I don't find this to be a problem at all: HP has done a very good job to conserve screen space. The extra space on the tis could be nice, but remember that much of it is always taken up by menu bars and other things which either aren't needed on the hp, or are part of the status area (shift keys, alpha key, etc). I am using the eight font, but that is simply because I find the other fonts hard to read. To sum it up: sure, a higher resolution screen would be nice, but the extra functionality, better software, community, availability and quality of programming languages, and flexibility far out weight a higher resolution screen. -- - Chris -- Visit Me at http://www.frostnet.advicom.net -- ---------------------------------------------------------------------- it is not simple to answer truely to this question i have an hp49g and i used an ti89 it is possible to say that the hp49 will do more things, but sometimes slower than the ti89 the ti89 is only good for simple problems the hp49 has more memory, and more math features hp49g@infonie.fr ---------------------------------------------------------------------- can be fixed, or if we have to wait for newer HP49Gs to come out to have them fixed?

The flash rom allows us to update these cars by getting the trouble reports from the field, identifying the exact conditions and develop a solution that can be flashed into the vehicle at a local dealer. I know the that the engine performance group I work in does their absolute best to give an error free calibration but there are only so many summer hot days and winter cold days to do real world testing. Environmental chambers can be used for a lot of the work but you can't tow a trailer up a grade at 0 degrees temperature with snow in it. The real world is a much more dynamic place and unfortunately some bugs will slip by. Flash rom is a saviour for fixing those missed opportunities. Dave Zelkowski ---------------------------------------------------------------------- Although the word sloppy occurs in my post about HP's 49, it was not used to describe the work of the ACO team. It was used in the context of the use and misuse of flashrom in general applications. The opportunity that flashrom presents to the manufacturer is beyond question. If it is used for upgrading functionality, or providing fixes for reasonably unavoidable errors then I applaud its use. There are some companies I know that could care less about the stability or usefulness of their software as long as the customer will still buy it and help them fix it. -- +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Les Nagy: President | mailto:lnagy@netaccess.on.ca | http://www.nas.net/~lnagy ---------------------------------------------------------------------- 10:39:14 CDT) I think it's a little bit unfair to say flash is bad because it encourages sloppy work. Just from reading the posts here (I don't have a 49 yet) it does seem like there are a few more bugs than in early releases of the HP48. Also there are features not yet included with the promise that they'll be coming along in the future. But is that bad? Isn't this a new way to make and sell a product? Get an adequate product out the door but let the buyers know more is coming. I think it's a fascinating idea. In the final stages of development, we all have one (except me, I can't find one locally) and and we have a place to post our opinions and the knowledge that the developers are listening. We're part of the development team. (except poor deprived me) Maybe when I get mine, I'll hate it. Maybe I'll love it. But I'm sure enjoying watching this process. My complaint, which may change when I finally get one and see MetaKernal for the first time, is that Jazz isn't included. I'm sure MetaKernal is very nice but Jazz is ..., well, it's Jazz.

The recommended calculator is the TI-85 (what the teacher will be using), however we are free to get whatever calc we want as long as we teach ourselves how to use it. Since a graphing calc is rather expensive, I figure I might as well spend just a little bit more and get a higher-end calc that I can use in college and beyond. I'm considering the highest end calcs from HP & TI, the 49G and the 89. I've rejected the TI-92/92+ as a possibility because its banned on the AP exams and because it looks a little too large and unwieldy to carry around. I'm interested in the HP-49 because of its ability to show step-by-step solutions to problems. However, the number of bugs being reported about this calc in the hp newsgroup concerns me. Also, its lower resolution screen seems to be a major disadvantage as well (how do the same graphs look when plotted on the TI vs the HP?) The TIs seems to be better accepted in schools, which means I would probably have better support in using one, since there will more likely be others using one as opposed to the HP. But a recent newsgroup post seems to indicate that the HP49G could handle more different types of integrals than the TI. How else do the HP & TI differ in math handling ability and capability? Are there any other pros & cons of each calc I should be aware of? I am considering engineering as my major when I go to college (either mechanical or electrical). Which calc (HP-49G or TI-89) would be better suited for my needs? Or should I make things easier for myself and just stick with the TI-85? ---------------------------------------------------------------------- UV User: Well, I don't know what they teach in math in colleges these days, but an SR-10 got me thru high school, and the SR-52, TI-58, and TI-59 got me thru college (Electrical Engineering). For you X & Y Gen'ers the SR calcs are (were) TIs. When I got a real job, I got an HP-41CX and never looked back. The raw power of HP's simply blow away the TI toys. Even today, the engineers in my department are almost exclusively HP users. Anymore - and I'll admit it - I buy calcs for fun. I'll tinker with them to see how they've advanced over the past twenty years. Relevent to this group, I own a TI-86, TI-89, HP-48GX, and the 49G should arrive by Friday. IMHO, the TI-86 makes a good game platform. The TI-89 appears to be geared to getting you though the math classes with the least amount of studying the manual, but the HP-48 series is a work of art. It's ability to support data structures that lend itself to complex simulations is unparalleled in a calculator. It is shear elegance. Go for the HP. Roger (Univ of Dayton - 1979) ---------------------------------------------------------------------- I am a Sophmore in high school and i just got a 49 and i love it.

Fisher ---------------------------------------------------------------------- Ok, after reading 20 very interesting post about the ti vs hp battle I have to say a word or two I have two hp's and one ti89. I think that Hp has a better tool!! I should say a tool and not a calculator because it is a tool used to solve math problems. I ti89 seems good only for a low learner, a to head agurments with five other Ti users. The answer is that the old hp, hp48, made even the ti92+ look bad with erable loaded. now the hp49 has erable with mahor improvements in all areas. So from a EE student, look at what you want to be. First a smart learner or a user of just a calcutor. I think that you well find you want a tool. A tool that you and you teachers will be able to solve your problems now and a tool that you can solve the problems of after school, when it is more than just what your friend who did not go on with school had. well Hope that this helps those outthere think about which Tool to get.

You *might* get a response a week after the exam in bit.listserv.calc-ti. This is the basic point. You will have infinitely more support if you buy \ an HP calculator than if you buy a TI calculator. The programmers of the hp49, \ in Gerald Squelart, Bernard Parisse, Mika Heiskanen, among others, know that these are the people who make your calculator work, and they will be more than happy \ to help with your questions. And if you're a do-it-yourself-er, there's no contest; with 4 different on calculator languages that are far more powerful than anything the TI can provide, you will be able to write what you need if that's your bag. These are just my two cents, but you'll find my sentiments replicated by every HP user out there; after going HP, I would never go back even if TI was giving out ti89s for free. Seriously.

First axiom of college education: Question the Professor's Rules :) Guess \ what the first lemming in the line recommends... Bugs I have seen reported are minor, arcane, or non-sensical. (eg TI bug report -7^2 reports -49 ad nauseum ) Capability, use, speed and practicality are \ far more important features in a calculator, particularly when flash updates are available. In general, I think it is safe to say lower resolution is disadvantageous \ only when accurate pattern reproduction is necessary, for most graphing purposes \ it becomes less critical. A resolution twice as high any default can be duplicated by zooming in at 2X. A zoom feature is included in the 48, and I make the assumption about the 49 having a similar feature(having missed the HHUC I \ do not yet hold one in my hands *sigh* ) From whom? In my daughter's high school class, the teacher gave a similar speech at the beginning of the school year. Help was composed of the instructions in the textbook published by a panel of TI automatons, and not \ by actual tete-a-tete query and rejoinder, since the teacher was busy teaching math ( thank goodness! ) not calculator use. Should you expect more calculator instruction in your senior year or college? Probably true, although such has not always been the case ( see textbook reference above for the reason why it may be true today ). Presently enrolled college students could better comment on whether this discrepancy is larger \ or smaller at college level as opposed to high school ( I suspect it narrows markedly at institutions of higher learning ) due mainly to the HP's greater programmability and high precision math abilities. This will be a tit for tat race until the ozone layer spontaneously regenerates. The Most Important Question is: will it handle the integrals \ you need? In electrical engineering you may need to learn to handle Laplace transforms, and most definately Fourier series ( EE majors insert comments \ here ). To me the most important asset would be the assistance and commentary of this newsgroup, and the resources provided on www.hpcalc.org and hosted by the underappreciated Eric Rechlin. If you have not seen the site yet, get a cup \ of coffee, a doughnut and surf there now. It is an amazing repository of a vast from the absolutely necessary to the very esoteric, this author's contributions falling entirely within the latter category. This depends entirely on YOU! TI sells a lot of calculators, so they aren't garbage. I do not find the HP48 difficult to use at all; the HP49 should be even easier for non-HP users to get accustomed to, so for me the choice \ is obvious. It is more than just possible that choosing an HP may make your life easier rather the reverse! At least mine has been more fun :) ( Steps off soapbox. ) Dennis ---------------------------------------------------------------------- CDT) I've never used a TI so I can't make a comparison but I'll tell you what I believe are two key engineering related features on HPs that I really like. #1. RPN - It's extremely usefull, especially for complex calculations. If \ you don't wish to use it however, algebraic is available on the 49 ( I have no \ idea why because once you learn to use RPN you'll never go back ). #2. Programming capabilities - In Mech Eng, I found I was often required \ to perform small, tedious, repetitive tasks. A quick UserRPL program would solve problems fast, at the desktop, and without the need for a computer. It's \ also relatively easy to learn once you master RPN. And, if you desire more powerful languages, for more permanent applications, they are available as SysRPL or assembly language. Unfortunately these are not supported by HP but adequate documentation is available and I have found that any questions will be answered on the comp.sys.hp48 newsgroup. Steve ---------------------------------------------------------------------- Was there much difficulty folding in the algebraic entry option along with RPN? Just curious. I won't buy a straight algebraic calculator, and I have great difficulty using one when I have no alternative. I wonder whether programming that entry mode turned out to be as convoluted as I find using it. If you idea ---------------------------------------------------------------------- Actually, I've heard that the TI-92 was banned from the AP exams not because of the CAS, but because it has a separate alpha keyboard. Apparently, the separate keyboard of the 92 caused it to be classified as a laptop/notebook/portable computer (which are banned) instead of a calculator. Thus, the TI-89 which is functionally equivalent to the 92 isn't banned, but the 92 is. If you ask me, it seems kinda odd to ban it for just that reason alone since most high-end calcs allow you to type in alphabetic chars (HP48/49, TI-85/86/89) even though they don't have a -separate- alpha keyboard. I think the 92 is the only calculator banned on AP exams. I don't know if that'll change this year or not tho. ---------------------------------------------------------------------- X-Priority: 3 The GX runs the processor at double speed, the GX has 128K of RAM built in, the GX essentially has the SX Equation Card built-in. Those are the highlights. From the viewpoint of someone who loved his SX dearly (me) the lowlights are: GUI-like interface. Try hpcalc.org for more info, they HAVE to have something... ---------------------------------------------------------------------- The 48S is slower, has no menus, and fewer functions -- but if you don't need those functions it's very comparable, IMO. For me the biggest irritation was the low contrast display. ---------------------------------------------------------------------- This brings up the question of who's keeping an up-to-date list of bugs that have been reported and verified to exist. We would also need to keep track of which bugs have been fixed in which ROM Ver. I'd imagine that HP ACO would like to hear about all of the bugs reported. But then, we all here wouldn't want to read about the same bugs numerous times....(like..There's a 1 on the top of my screen.....) With such a list we can steer posters to check the list first. I'm getting the impression that there many bugs - the list may have to be organized by catagories to help search it quickly. I think we need HP's imput on this, and that they may have their own list - no sense in reporting a bug when they already know about it. ( But we would like to know about them!) So far from what I've seen, I'm impressed, but I'm a little bummed by the nember of bugs.

JD ---------------------------------------------------------------------- First of all the manual says to edit a usr RPL variable, I think it calls it just a variable, that one should use the file browser thing the press NEXT NEXT and F4 which is EDITB. Being the slightly, at least, informed kind of guy that I am, I put 'prog' on stack and type in EDITB as a command. When I hit enter the stack var, 'prog', come up wanting me to edit the name, not the contents as in the case w/the 48 series. Furthermore the same is true if I just try EDIT. So why do I have to do this through the file browser thingy? Is there an easier way? This leads me to my next must-avoid item. I hate the menus...is there a way to avoid the menus a la the 48G/GX? Those 2 calcs you could get/do the same thing via softkeys. Usually meant pressing right shift vs. pressing left shift. I have found no way to bypass the menus of the 49g. Anyone else know of a way? Finally, how the hell do you convert a unit to a different base? Say I want to convert 1_yd to ft. On the 48 series you get to the units, go to length, put a 1 on stack (if you wan to avoid error beep), press yd which changes the 1 on the stack to 1_yd. To convert I'd just press right shift and the desired lenght I wanted it converted to, in this case I'd press ft. This would have the desired effect of changing/converting the 1_yd on stack 1 to 3_ft. On the 49g it seems to be much more of a pain in the ass! If I trudge through the damnably evil menus find my first unit say yd I can get the 1_yd on the stack easily enough...or I can manually type in 1_yd, which is infinitely annoying but much faster than menu-hell. Anyway so now I'm wanting to convert my 1_yd to ft. Intuitively I guess that I would leave it on the stack go through the menus to the unit I want to convert it to. So I do just that. What I get is 1_yd*ft. This is clearly not what I wanted. Can anyone let me in on the trick?

(Reading on page 80 of the pocket guide...) I tried using this, and the result.. nothing. I also tried using [ON]+[F1] to obtain a screen dump. This also does not seem to work -- the I/O symbol in the upper-right does not light. [APPS], I/O Functions, Print Display (and Print...) both work well. Any ideas what might be going on? The [ON]+[F3], [F4], [F5], [+] and [-] sequences seem to work as expected. I'm not sure about [ON]+[F2], as I'm not sure exactly how it should work. (E.g. I hold down [NXT] and while pressing it, additionally key in [ON]+[F2] and then release [NXT], but it has no effect. In theory, shouldn't this have canceled the [NXT] keypress? I've yet to try [ON]+[F1]+[F6] as I'm not quite eager to erase my memory. (Though, the other night after using RISCH and then pressing [DOWN] to edit the result, the screen became garbled and I received the Recover memory? prompt. (I tried the problem again, and it did not re-produce.. I will keep working on this one.) About an hour later after reloading the memory, which was completely lost, my screen just blanked out while working with the calc. The on button was completely ineffective, but the reset button brought it back to life. I once again received the Recover memory? prompt, and this time the calc was able to restore a portion on what had been in memory.) Are these same types of problems happening to other HP49 users? I am especially curious about the [ON] sequences, as I'd like to use [ON]+[F1] to get screen dumps.

Mart222nez the manual ---------------------------------------------------------------------- X-Priority: 3 Just a guess: the 512K RAM means that there's a 512K chip (or set of chips) in the box. Some of that RAM is used by the system to provide things like the stack display, command line, keep track of the time, etc. The TI-86 for instance, has 128K RAM, but only 96K is available to the user; the rest is reserved for the system. Similarly, a 128K HP48G+ or GX doesn't have quite 128K RAM available to the user (but far closer than 96K). A 32K HP48G has about 28K available for the user. That would account for the 10K or so to 256K; I think the other half is in a port (port 1?). As I said, just a guess. I do not own (and don't plan to buy) a 49 so can't say for sure. ---------------------------------------------------------------------- Ah! Of course! I forgot. The ports. Yes. Forgot them because the 49G doesn'n have any expansion slots like my good old 48SX and 48GX ... Ok. I switched to the LIB menu and saw four entries: HP49D, :0:, :1: and :2:, the first being a nice HP49G demo, library 1234. Then I remembered the MERGE command and looked up my 49 pocket guide: the stack diagram says I have to put the constant 1 in stack level one and then type in MERGE. I did this. All I got was a MERGE Error: Bad Argument Type. Same with a 1. on stack level one. :-( So: how do I merge ports on the 49? And what about port 2? Any discussions about this here recently that I missed? I think this should definitely go into the 49FAQ! Stefan. ---------------------------------------------------------------------- they Sorry. to me, it seems the port numbering is off from a 48. For 256k RAM would be a GX with port 1 already merged. Here, with the 49, port 1 appears merged permanently, and port 2 is now called port 0(otheriwse, with port 1 merged, you couldn't write to port 1. Either way, memory is still managed in 128k chunks. Makes sense? Share what you know. Learn what you don't. ---------------------------------------------------------------------- Main memory, Port 0, is 256Kb. The rest of your memory is in 2 128Kb ports, 1 & 2. You can do an ON-E and then the memory test (full), I think and it'll show you. Or go to the libs/ports and check it ou tthat way.. I'm wondering if both of those could be merged such that a full 512Kb could be seen as port 0, or main memory?

I often use dangerous betaversion of new software, such as Java 3.7b for testing purposes. When (not if :-)) it crashes, I try to ON-A-F it. It asks the dreaded question and I say yes. Now it recovers memory, and it recovers and it just keeps on recovering... Once I left it for over an hour and nothing happened! I've even used the hardware reset behind the upper right rubber foot to clean the calc, but it doesn't help. I tried removing the batteries once and drained the remaining power by pressing a lot of keys simultaneously for a few seconds. I thought that would make the calc stop. Then I switched it on (well, I put the batteries back in first :-)). Surely, it was totally clean, and just for a laugh (oh, yes!) I pressed ON-A-F, and answered yes. But it kept on recovering and recovering... ??????? Why???????? I know my HP has functioned properly, and it usually recovered for only a few seconds before returning to a normal state. But after the first time it did that, I've never been able to recover memory. Share what you know.

I own the rom card version 2.2 of metekernel and would like to know 1) is it legal to use on the emulator 2) how can this be done? I have copied the contents from port 1 to port 2 on \ my RAM card . The problem now is transferring it to my PC to run under the EMU48 program? Also, if this is not legal. Is there a file manager similar to the one that exists in the metakernel card? ---------------------------------------------------------------------- x = 1. Is it left to the user to check the result (for example with SUBST)? Michael -- ---------------------------------------------------------------------- (x-1)/[(x+1)(x-1)] = 0 1/(x+1) = 0 .. with undefined value at x=1 I don't see how it gets x=1 from this, except by (x-1)/(x^2-1) = 0 x-1 = 0 x = 1 But of course, this is a common mistake and should be trapped. Always a good idea. ---------------------------------------------------------------------- 3 + LOG(111) and right afterwards type ALOG (i.e., 10^x): ALOG(3 + LOG(111)). I'm not able to simplify this result back to 111000 by any of the 49's Now we change (1) to 111 e 3 ^ * LN and simplify it with TEXPAND: LN(111) + 3*1, then EXP and TEXPAND again: 111*EXP(3). Why is LOG-ALOG treated differently from LN-EXP?

The Italians claim him as their own. Cristoforo Colombo was born in any tourist trapped in that city. He couldn't get financing from his trip, so he went to Portugal and to Spain. The Spanish called him Cristobal Colon. (That's an accent grave over \ the o, I think.) Ray ---------------------------------------------------------------------- ^^^^^^^^^^^^^^^^^^ This is the bug you're intending to talk about? The rest of it says 'feature' to me. ---------------------------------------------------------------------- I just got my HP49G from BBMarketing here in Sweden, and thought I too would give my first impression of this new toy of mine. First of all I must say that I was rather sceptical when it first was this group, that sort of changed my mind from the first disappointment to a must test this new stuff-feeling. I think it feels more solid and better built than my old HP48GX (from 1993 or 1994) which I can twist and push the case a bit to get some sqeaks (irritating noises) from. The keys are rather good, but I keep getting the thought in my head that the text on them will disappear with some use, do not know if that will happen, but it feels that way. The new slide-on cover feels OK (thanks Joe for the tip to get it of !), and looks much nicer in real life than on the pictures on the net. I too have the annoying rainbow at the top of the screen, which seems to be a standard feature ! The version is HP49-C/1.05 as everybodys else's. I must comment the roumor about the registration card that you are forced to choose 1 of 3 books, my card says that I can choose 1 or more books ! That should mean that one could have all 3 if there is need for them ! In the Flash-memory I found a demo-library, number 1234 with size 106 kbytes, which gives a rather nice run-through of the features of the HP49G. Is this library something that is put in every HP49G or can one copy it from from the system-Flash ? What I miss (already) is some kind of AUG, but I hope to get that soon ! The firsts impressions this far are good, but I have only had it for 5-6 hours yet ! Keep up the frontiers work Joe K Horn, I am waiting for some new thrilling features ! ---------------------------------------------------------------------- 49, and they all say that they aren't going to get it until JANUARY. Darn it, darn it, darn it. Luke ---------------------------------------------------------------------- So drive to Portland, or mail order...
