A33 I just downloaded the 39/40 ROM in my 49G, and I am wondering which program I should use to download aplets in my transformed machine: the 49G's or the 39G's? What's the name of the program to be used? By the way, I am happily surprised by that 39G. Still have my 48 though ... Tried it. Seems the 39G program is the one to use. When I was beta testing the 39G using a ROM downloaded into a 49G it behaved in every way like a 39G, including expecting you to use the 39G's comms software called HPGComm. Go to my Utilities page and you can download the latest version if you haven't already got it. Or go to the author's site (James Bergamin). You can also find instructions on how to use it at my site if you haven't figured it out (it's not hard). PS You may find that it's easier to use the emulator to explore the 39G since that way you get the proper keyboard too. I agree that the 39G is a great calc. -- Colin Croft Applications in Mathematics ccroft@iinet.net.au http://members.iinet.net.au/~ccroft/ Ah, you're right, the keyboard ... But I find easy to adjust to it. And I like the machine. I'm seriously thinking of keeping it that way for now ... -- Thierry Morissette tmorissette@hotmail.com 3BEA94DA.1D2ABD60@iinet.net.au... program the ... behaved in software version Bergamin). since I have been using my 48G on cold mornings and it has crashed a few times requiring the ON-C reset. Enviromental limits are listed at 32F(ZeroC) but I am running well above that temperature. Seems to be more reliable when the device warms up. Has anyone had a problem with this? http://www.Gnarlodious.com/ I have the 48GX which I used out of office in the coldest days of winter. No problem. Only the display loses a little contrast and is a bit less responsive in the cold, but when in warm again it regains its contrast and update speed. Nick. Hi all, I am having some problems doing indefinate integrals on my 48GX for my calc III and diff equations classes. I know that it doesn't support many integrals but was hoping to find a program for it that would. Unfortunately, most of what I have found either uses the calculators own deffinitions or may be too big, I just found erable and am going to look at it. programs like erable may be too large for me. Any suggestions?? Kevin dgeve: I think that his project and yours may be complementary works First and second section of Programming in sysRPL by Eduardo Kalinowsky are a good start point. (Of course you know this book, do you?) Although it refers to HP48 models, many things, if not everithing at all, may be applied to HP49. Ciao, Marco === Subject: Re: [49] Exact to approx. conversion problems -0600) Virgil inquired: This is, of course, the same as editing in Approx. mode and then just pressing ENTER, as was elsewhere suggested; it works on programs, lists, arrays, numbers, etc. as well. -[]- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 80,000 Newsgroups - 16 Different Servers! =----- Lo people ! I encourage Steen Schmidt in his great project, but a still have a newbie question ..... Can anyone tell me how to do text formatting on hp49 I want to put my phisics, math, and chemistry lessons in it, so i need to put equtions and etc ... The top notch would be to right the lessons on the PC then transfer them on the calc .... Thx in advance .... I use Lupa for that purpose, and works very good, the only remark is that you have to convert yor formulas in grobs for pretty print view. Thx but how do i do that ? (i know im a BIG NEWBIE) Thx in advance ! Matthias You can assemble such texts with WinHP on your PC and transfer them to the 49. Install the TGV library to view them on the 49. Both programs are available from hpcalc. Greets, Marco the only problem I 've found with TGV is thai it doesn't use minifont reducing the number of characters per line. 1. Download from hpcalc lupa49 2. create on your pc, using your preferred text editor, a list containg all the information you want: ex: {Hi GROB 10 x 10 } 3. Load it in the calc 4. recall the list on the stack and launch lupa That's all I believe that TGV is just a straight port from the 48, no 49 or MK specific feature was implemented in it. Greets, Marco There's PrtyChem on hpcalc.org that converts strings to grobs for nicely-formatted chemical reactions. Physics and math you can mostly do in the equation writer, except that you'll have to use multiple-character variables instead of subscripts. There are tools to view text and grobs at the same time on hpcalc.org, if you even need to do that. Would something like an equation library work? *That* would be best? How terribly time-consuming! How horribly dependent it makes your calculator! How awfully tedious, that you need a computer accessible! 'Dune' is for the 49G, 'DuneGX' is for the 48GX. Both are available from hpcalc.org Here's what I have to say about Dune: This is a game similar to Warcraft, Starcraft, Red Alert, and such real-time strategic games for the PC. You are on a desert world, with great deserts, rocky 'islands', and mountains. You can only build on the rocky 'islands', and your units (your machines, that attack and explore and have various uses) can't cross mountains. In the deserts you find great worms, that move consume units, and spice-rich areas. Spice is your principle resource, which you need to build everything, and there's a finite amount of it in each area. You start out with a building the sole job of which is to build buildings, and some units. In later levels I think you start out sometimes with more buildings. This game has levels; in each one you start out in some rectangular area of the planet. Your enemy also occupies this area, and you have to destroy him =) -- meaning that you have to destroy his buildings. While destroying him you harvest spice with special spice-harvesting units, you fight battles with your many war-machines, and build more buildings to * generate energy, * hold more spice (if you harvest more than you can hold... too bad! you lose the excess), * repair units * attack enemy units, and * generate units. You can also lay down concrete and something else (I forget at the moment) which units can pass over and which allow you to build a building a little farther from your other buildings (normally you have to build each building adjacent to a building you already have, and after a while it'll be hard for your units to navigate your own base -- this can be fatal!). In the game you can create 'mobiles', which are units that build the building-that-creates-buildings, and with these set up what I call 'outposts' on other rocky 'islands'. OK. This game is fast enough that I have never at any time noticed a delay in its action. It's beautiful enough to lend much atmosphere to the game, and to be generally impressive. It's gameplay is enough that I am only annoyed on a few small points -- and very little annoyed at these. You can move swiftly about the map, and yet also move with great precision -- done by a cursor operated by arrow keys for broad movements and the number pad for precise movements -- which is a wonderful idea, and I hope other such games imitate it. Moving about the map, selecting and employing units and buildings, is very easy and simple to do. You can call up a map, which gives you a general view of the area ('lo, there's my base and there's his base and there's my other base and here is a lot of spice). Here are the parts of the gameplay that sometimes annoy me: 1. There is no visual distinction between enemy units and friendly units. I can either simply know what's what through my masterful awareness of the location of my units or (most of the time) just select a suspicious unit and see if I get a menu to command it. If I don't, it's an enemy! There is likewise no visual distinction between enemy buildings and friendly buildings, but this is no problem. 2. The map isn't very good at showing units, and isn't at all helpful when I *know* that *somewhere* I'm being **ATTACKED**. The key, once again, is a masterful awareness of the exact locations and actions of all your units and the likely locations of your enemy. 3. When a great campaign is entered, and I'm trying to multitask at A) defending my base from constant attack, B) defending my harvesters of spice, C) expanding and exploring, and D) attacking the enemy... I sometimes lose track of one of these and find myself hurt or beaten. One time I lost an entire outpost, every building smashed by probably a single unit -- because I was so busy defending myself and exploring that I didn't notice the messages that flash to tell me about each building being destroyed... You have to be *aware* of the map. Have I said that several times, yet? If you play the game, you'll quickly see what I mean. You can't get distracted; you can't not pay attention; you can't be slow in jumping across the map to command multiple operations. I'm not really sure if this is a bad thing, but it would be nice if I could see my enemy more easily. That's all that's bad. Really. When you exit a game of Dune it puts some data on the stack which, if on the stack when Dune is started, will continue your game at that point. I've written a simple program that handles this data for me. OK, I'll list a few important points about the game now: 1. it's graphics are *great*! 2. it's gameplay is *great*! 3. it's really, really fun! 4. it's almost completely in French, which is no problem except that I'm not totally aware of the instructions for each level. The gist of them is basic: kill the enemy. 5. it takes a little getting used to, even if you're familiar with similar games on the PC like Starcraft. I think that's enough about Dune. You should all go and get it now, OK? I'd tell you more about the strategic points of Dune, but I worry that this would dimish your enjoyment of the game. You'll figure it out =) (note: for those of you who don't speak French, you should probably pick up a French-Whatever dictionary and look up the names of each unit and building. The function of each should then be evident.) HPTIDE version 0.3.2, a tide prediction program for the HP48 and HP49, is ready to go. Based on the popular WXTIDE by David Flater, there are over 2000 locations ready for your tide prediction pleasure. You can examine daily graphs as well as produce a tide table for your own locality. You can download hptide at: http://heygus.2y.net/hptide until the new version is posted at: http://www.hpcalc.org/hp48/apps/misc/ Dennis This is quite a trivial problem that is to be solved and I'm not sure if the error is due to some setting on the HP49 or otherwise: Equation: P = R^(-N) Specify: R = 0.001 N = 4 The solution (by using the normal calculation part of the HP49) is easily found as being 1E12. However, pushing the Solve button for P (or pusing it twice to watch its progress) results in the solver getting close to the answer, but then it bombs out with an Error: Bad Argument Value. You have to go into the memory to clear one of the variables in order to get back into the Solver environment (else it just keeps on bombing out over and over). I'm sure this is a feature related to the number of significant figures that can be displayed without resorting to scientific notation, but am I to understand that you cannot put in values in scientific/engineering notation in the Solver fields ? Kevin This is for the 48. On the 49 the ADISP GROB has always 64 rows. So you don' t have to resize it. X Haa - HP is finally *really* going back to it's roots: The measuring devices eg. Agilent is manifacturing the 12C CPU nowadays!!! Could this be true? Maybe they will make the future HP 5n GX models, too??! Veli-Pekka, STARTing rumors again....what NEXT ? I think calculators can be a very valuable marketing asset for Agilent. HP calculators have been the first contact with HP for engineering students, and I guess (this is only speculation) that it has had a strong influence on the preeminence of HP workstations (compared to Sun) in engineering shops. Of course, another factor is the excellent quality of HP instrumentation, now manufactured by Agilent. I think that Agilent would really benefit from the excellent brand image HP calculators have or used to have. Borja. P.S: I am not a marketing professional, just a curious observer. Not that I abandoned hope, but with all critisism against calculators there are 2 things possible: 1) We wont see an HP calculator again. 2) HP is aleady working at some future model, which is going to be the absolute breaker. And they don't want anybody to even assume that the next thing is coming up. I dream about the second possibility. :-) Hmmm, perhaps they (HP) need some convincing (assimilating) arguments, to make the HP 5n GX. Should we send rcobo, assimilate them and convince them to do the right thing? Nick. (willing to join the rumors stream :-) ) Karagiaouroglou says... yes, yes, they need to believe. seeing is believing. they need to see the making of the machine. they will be assimilated. I had the same thought when I saw the photo of the chip with Agilent printed on it. I assume that Agilent must have many ASICs made for them for use in their instrumentation. I realise this is a very simplistic view but with Agilents' vast design resources, why can't they design a faster Saturn that supports a bigger LCD display for example. That way we get to keep the existing huge software base. Frank Andrews 3 of 3 to mainBorg: Comms protocol set to red_alert. Testing assimUnit......OK Testing convinceUnit...OK Testing screwDriver....OK All subsystems up and running. Ready for assimAction. 3 of 3 awaiting further commands. Beep Beep! Nick. Hello maybe in the future, as people should never say never. definitely no. Jean-Yves Mon capitaine, I am glad that you said this. :-) Sometimes definitely no is definitely yes. Or do we expect that if HP has such plans, they would tell anybody? Of course not. They would always say no. So for us, outside HP, there is no way to know if no is no or if no is yes. So the only possible thing for me is wishful thinking. Anyway, thank you for still being here in the group JYA. (And have me getting on your nervous with my wishes on a new calc ;-) ) Nick I love RPN and quality HP calculators. I've never owned a TI that lasted more than a year before it went from an expensive toy to a cheap piece of shitty plastic with the worlds poorest keypads (not counting the HP-31/32/33/34 switches which were on a par with TI's). I've been an HP user since 1977. The raw computing power in a Pocket PC (even my $199.00 Jornada 525) so overwhelms the processor speed and memory capability of an HP-48GX or an HP-49G that I don't see a real need to have a dedicated piece of hardware called a calculator in the future, though for sentimental reasons I'll continue to keep a 48GX at home, one in the office and back them up with my HP-15C, HP-42S, two HP-28Ss and when the enemy is finally at the gate and I'm too old to read the LCD screens, my HP-67 with its non-continuous memory and its bright little LEDs. After that, I'll fall back to my Post Versalog and my K&E Log Log Decitrig. :-) I expect that it will be a lot easier to have a killer calculator living next to WORD and EXCELL in a fast Pocket PC than in any other hardware form. This is not what I want, but it seems to make sense that it is the direction things are heading. This disassociation of hardware and calculator may make the calculator world a frightenly powerful place to live. Just my $0.02 Jim Klein (snip) Other than disbanding ACO, what have they done? (snip) The ROM's future is uncertain right now. JYA has mentioned that he will try to see it GPL'd, and a lot of people have supported this with their voices here if nothing else. If the ROM goes GPL, it is basically freed for public use, modification, and redistribution; so a good hacker could fix a few bugs, add a few features, optimize a few routines, and release the hip new 20-x-jrf7Dec2001 ROM, and communicate his improvements. You could have patch sets, and development tools, and modular ROM distributions, and groups of people working on different parts of the ROM, and all *kinds* of such neatness. We'll have, basically, our own operating system to improve and play with on hardware we've bought with our peers. I think this would be tremendously cool. Have you heard of Linux? Anyway, I think you overestimate the place of the ROM; the 49G is pretty extendable any way you look at it, so it's not as if you are *doomed* if the ROM is static and opaque. Case in point: I notice that nobody has bothered to put a periodic table in ROM, yet! (and there's no graphical memory viewer, but just *look* at how many of those things people've made!) If you're a programmer, all existing code is a jumping point toward future improvement and developement and usefulness -- no matter what happens. Sure, in the year 2043 you may have to torture Steen for a few days -- but eventually he'll tell you how to crack his library, and you can add the feature you always wanted to it! (This is a joke, of course; by 2043 we will have wristcomps.) This is certainly a danger, and as time passes it is a certainty. When those braincomps and wristcomps come, my 49G use will certainly plummet. The community will shrink too -- and, relatively, it's already shrinking, been shrinking, and will only shrink faster; TI is sucking up more and more people and few will care to hunt for other calculators when they A) do not know enough to know what they lack, and B) are satisfied with this ignorance. And as you've seen and as you can see in yourself, a lot of people seem to be taking ACO's departure as a deathtoll for the 49G; some of these will leave the community and use other calculators. More may never come, when the word is spread about how the 49G is 'unsupported'. So, if your concern is with the 49G community, I hope I've properly fed your fears. Hey, just by having a calculator you are way in the minority! And do you have a computer? Whew! Better not instigate Fortunately, you have either practical or ... nonpractical use of your 48GX, and have some idea of what the 49G will mean to you. If a TI-92 or somesuch will fit your needs and your personality, and you think the benefits of support and community outweigh the advantages of flexibility, extendability, and a really astounding number of man-years and ingenuity that exist in the 49G: fine! Buy the TI-92 and be happy with it and never look back. I'd never do this, but I don't have time to add the little footnote explaining why. Maybe tomorrow. (snip) I just got a 48GX yesterday. I have no manuals or cables (yet). I had a 28S that I used and programmed until it stopped working after I had a motorbike wreck with it in my backpack (n.b.: don't do this), so UserRPL is not new to me. However, there are several things I have forgotten, in the intervening several years. Is there an electronic primer somewhere out there? -- -eben eQbWeEnR@gTaYtUeI.nOePt home.tampabay.rr.com/hactar This message was created using recycled electrons. You didn't answer Dennis's questions. How have you set the calculator in a mode where it will answer the PC software? R-shift HOLD Right-arrow brings up the mode for HPComm-whatever. R-shift Right-arrow (no hold) brings up the mode for an X-modem connection. Which did you use? You might try the X-modem part, too, with corresponding PC software from hpcalc.org No option is necessary. dgeve: If ON+A+F doesn't work, try to reset the 48GX by pressing the hard reset button; you can find it removing one (I don't remember which one) of the rubber plugs placed in the back of the calculator. Iou may need something sharp to press it (like a papaer clip). Remember: both methods involve the loss of all data stored in your HP (so backup if there is something relevant) Ciao, Marco /-----------------------/ Marco Tinarelli - Bologna - Italy tittiXXYYZZ_tt@tin.it (togliere XXYYZZ dall'indirizzo per rispondere) (cut XXYYZZ from e-mail address to contact me) I see no such documentation, or such support, or such a manager. Perhaps these come with the other Babal package on hpcalc.org, whose description offers 5 more levels for Babal? I'll look at it. A lot more at http://www.hpcalc.org/hp49/docs/misc/ -- and most relevant to the 49G, especially for programmers. Ugh. I mean http://www.hpcalc.org/hp48/docs/misc/ is anyone else using the X48 Emulator for MacOS? I find it impossible to get it to keep time accurately. Is there a way to make it read the MacOS time? When I shut it off and back on the clock is way off. I am using Euro format on X48 but NA format on MacOS, is that a problem? http://www.Gnarlodious.com/ my copies. There are two different versions, an older clasic version and a newer carbon version and both of mine keep pretty good time. But what you may want to check is that on the carbon version before version 0.9.1 the ram was not preserved. You may want to see if you have the latest version. Dave On Sun, 11 Nov 2001, You've missed unfortunately the major advantage of using the RPN notation. You need far less keystrokes and you see intermediate results. So your whole analysis is flawed. I bet if we organized a a contest on time to key-in an equation, most of the people using RPN calculator would won. In my life I've been in only one case where somebody was faster than me to key-in an equation on an HP48. It was my physic teacher in year 11, he could do everything mentally and usually got the result on the blackboard before I had finished to read the equation. But these kid of things don't happen often Jean-Yves My rebate arrived today 9/17/01 Yes, mine came today as well, 9/17! VW Mine came in today (09/17/01). Rich Opps, mine was for the 49G. Just re-read the subject line. I am looking for a program which is able to receive Ascii strings at the serial port. The strings are sent out from a 8051 microcontroller every 15 minutes or at special events. The strings should be stored in the HP. Once all strings are captured I would like to send all strings to a PC by the same time. I am quite familiar with the 8051 assembly language but not with the HP-48 so therefore it is easier to customize the 8051 side. I browsed a lot through the hp-48 websites and saw hundreds of programms which may suite. Maybe there is anyone who had a similar problem and found an exact fitting software. Is there some kind of a sleep mode where the HP goes into after a certain while without receiving data at the serial port? This would safe battery Power. Martin I think Detlef was referring to the power usage of the hard drive itself. Not the adapter... If you need an extra 10kg to power the harddrive, it may not be that interesting anymore Jean-Yves hard the Hello. You *NEED* a cable. The advantages are huge. If you can buy one then is very very easy to made it for yourself. Look the next files: http://www.hpcalc.org/hp49/pc/pictures/adapter.zip http://www.hpcalc.org/hp49/docs/misc/cable49g.zip <-- this is THE file Be very careful with the connections, but it's easy. Then you can upgrade your rom to 1.19-5 (will avoid a lot of bugs) and save a lot of time and effort. Saludos Jorge M. Valenzani I'm just starting to learn programming System RPL. I use my old HP48SX to test my programs before I put them into my 48GX. The problem, I'm trying to use the example Inputline program from RPLMAN.DOC and I can't get the example program to work. I get the prompt, I can type in Input, but when I ENTER or try ON, I get nothing, I have to warmstart. The User RPL INPUT command works, but not the System RPL equivalent. Any help would be appreciated, otherwise my budding programming effort might be cut short. I'm pretty sure there is a list somewhere of all the different types availble fo Ck Dispatch arguments. I have the list of simple ones. I'm looking for the lists of things like one real and a list, or matrix and real for example. Can TW ~The enemy's gate is down. Harold A.
