Otherwise, all the tools present in the HP48 (including the numeric solver) are the same than in the HP49. The new SOLVE commands handle units as well.

When you are spoiled by a 28's keyboard, the 48 or 49 appears to be missing something. With all the change at HP, I decided to finally get a 49 before it was too late. No stores in my area had them (or even stock them anymore) so I got one from amazon for around $150. I didn't even think I would want to use the ALG mode after RPNing it for so long. So far it can stand it out side of the occasional beep from hitting enter when I shouldn't be. Well, kick me because I love the thing and can't believe I didn't get one when they came out.

Trying to compile a program with the Jazz library By Mika Heiskanen the calculator stops and there was no way to restart it by pressing any keys (olso the rear microbutton under the foot won't work). The only way to restart the calculator is to remove the batteries for some days. Is there anything I can do?

My God.. I think you fried your ROM when you called by mistake one of the very hidden HP48 entry point : =NukeTheBstard EQU 666 Lucky that Cynox told you that they could fix it. I was not aware that it was possible. Send it back to them as quickly as you can while it is still safe. Make sure first that you roll your calculator into 5 layers of alluminum paper covered with Colgate Total+Whitening toothpaste, otherwise the problem may spread to all electronic equipment around and you will fry all rom. ==== Joke aside. Turn around your calculator so you will look at the back. Remove the upper right rubber feet and you will see a hole with a R next to it. That's the reset hole.

That's the anyway I try to do as you told me and when I have pressed the [ON] key (in [ON]+[A]+[F]) the calculator stopped!!! And it is still blocked. Now I remove the batteries and this night when I'll be back home the calculator will'be still blocked. I don't know if there is the possibility to corrupt an internal register (I think so), but now every time I press the [on] key the calculator stops, and I must remove batteries for a few days before it lives again! I don't know if Colgate Total+Whitening toothpaste can do anything for my hp, in my home I have a little nuclear reactor and the good ray it radiates in my bedroom hasn't the same good effect on my hp that it has on me :-) Bye. Stefano ==== > anyway I try to do as you told me and when I have pressed the [ON] key > (in [ON]+[A]+[F]) the calculator stopped!!! And it is still blocked. Don't worry too much about that calculator stopping. First of all remove any ram cards you may have in your calculator. You can't damage a ROM, that's why it's called like this. There's no need to remove the battery for a long time. What you can do is: -Remove the batteries -Press and hold the ON key for about 30s -Put the battery back -Press ON. It should turn on with the message Try to recover memory. You can also play with the reset button and pressing the on key until you get it. Don't worry, your calculator is more than surely fine. However, there was a bug on the HP48S and G series that could prevent the calculator from powering on once you put the battery back in. This bug (software) had been fixed in the HP49. Even with this bug, playing with the reset button and the ON key you can restart t. It is just a matter of experience. ==== I'm forgot to say that now when I press the [ON] key the calculator stops and I must to remove batteries for restarting it. ==== After I requested an example I had a bit of a play and found that one.

Now, if you tell me where in that sentence you find the > gratuitous by any means, and at any cost that you added If a law states that a company has to maximize shareholders profits, a company has to do that. No exceptions. You should have said then As a publicly held company, HP has a duty, by law, to seek to maximize its shareholders profits. The business law really doesn't even state anything like this - a company that has to make a decission is free to make the decission that fits the company, or any of its boardmembers (within the criminal law). If that decission is important for the companys financial situation or for the general state of competition on a particular market, the company has to publish information about the decission in advance. How long in advance is not stated by law, but a court can decide if an amount of time was too short. THAT can be expensive. A similar ruling can be made regarding importance and scope of decissions. A company is not responsible AT ALL for its stock value. It's a gamble by the stock holders, and theirs alone. IF a company stock drops too quickly, there is a chance that many or all stock holders will bail and crash the company financially. THEREFORE it's not recommended to hide important decissions (which can quickly make a company a big empty shell). Often a company crash was lead by one or more criminal acts - someone acted in ill intent - didn't disclose that particular piece of important info. ==== Ok - my curiosity made me remove you from my killfilter again. > > But they are, largely (because they are driven by secondary goals). > > Being driven by secondary goals is not the same as being an idiot, > I'm sure you will agree.

Unfortunately, the name HOME is hard coded into the Filer and the stack display engine. I never thought that people would have liked to change the name so I didn't include the capability in my design. The header stack display is done entirely in ML, looking for the name of the HOME command would have been quite difficult and would have slow down everything.

I would also like to be able to plot the > real,imaginary, magnitude, and phase of the FFT. Though I don't have any idea about the command stem of matlab, I suppose you want to plot somthing like a bar plot, with the height of the bars representing how big the real part, imaginary part, magnitude or phase of the fourier coefficients is, and the location of the bars representing which harmonic you plot. Well, let's say you have the vector [that results from the command FFT. With this vector on stack, enter a 1 and then use the command COL->. This makes a one column matrix that has as many rows as the vector had elements. Issue the command RE if you want real parts, IM if you want the imaginary parts, or enter << ABS >> and issue the command MAP if you want the magnitutes, or enter << ARG >> and use MAP if you want phases. Now use STOSigma (Sigma is the greek kapital letter sigma) to store this matrix in the matrix SigmaDat, used for statistics. Choose Bar Plot as plot type, autoscale and plot. You can of course construct a matris that contains real parts, imaginary parts, magnitudes and phases of the fourier coefficients as separate columns. Then you can plot whichever you want, by selecting the appropriate column in the plot setup window. I hope that it helped a little, Nick. ==== R Lion escreveu na mensagem > I'm looking for a good condition HP15C, preferably in Europe. > Don't worry about serial number, only a working calculator is wanted > www.ebay.com www.hpmuseum.org to say a few... search for HP15C for sale. ==== Peter Karp <2002@karpfenteich.net> escreveu na mensagem > > it's been quite some time, since I last looked into the newsgroup.

Every calculator has limitations. I like my TI-92+. But I prefer RPN logic(rulez for complex expressions like: (3*4*5)/(6+(5/(4+3/(5-3))-SQRT(3*PI)))))-COS(2) ' Even get lost on the parenthesis!).

On the real calculator the sound is made by setting an output port in the right frequency. This isn't emulated in Emu48. When you're using a ROM patch like BEEP.EXT or something like that modifying the =MAKEBEEP routine, the emulator is calling the WinAPI function Beep(). But the Beep function work only properly under Win NT/2000/XP. On Win9x/ME you're getting only a default Windows sound message. > And is there any way to make an loopback to load files into the 38? The only way for the 38 at the moment is an external Nullmodem cable connected with COM1 and COM2 (or other, Emu48 supports up to COM16 serial ports) on your computer. A cheap one with three lines, where pin 2 and 3 is crossed, will be enough.

If not, an emulator could be written > in it and the entire ROM could be used. PalmOS divides RAM into two sorts, dynamic and storage. The dynamic heap is used for program stack, global variables and anything the program allocates on the fly. It's 256KB on an 4 or 8MB device (128KB on a 2MB device), though, the OS takes around 64KB of that. The storage heap is used to store databases and is write-protected by the hardware. To write to the storage heap, you have to go through OS functions which check you're not overwriting anything you shouldn't be. Whilst you couldn't allocate enough dynamic heap space to emulate more than a 48G+, you can store the ROM image in a database and have full read only access to it. In fact, i have 48G and 38G rom images stored on my TRGpro (8MB to check the CRCs. It takes about 20s to check one, but i'm sure it could be speed up with some assembly language.

Because if it was possible than the fall of the HP calculators have begun at the release of the HP48GX. Let me be clear,the HP48GX was a great calculator but HP was targeting both students and professionnals with the HP48G series,thus HP had to keep these calculators cheap. The consequencies are that the HP48GX was less powerful than it could have been thus certainly pushing pottential buyers to look for alternative like PC with more horsepower and which better fit their needs. What do you think ? ==== > What do you think ? Why do people think that more { memory MHz pixels } means better calculator? The GX is the best calculator that will ever be even though it is old.

You did a great job with the 49G... the rest of > HP did not... I have had my HP49g since about one month after they were released. To Be truthfull, I haven't used it as much as I would like or as much as my other HP calculators (that I loved so much). As with most of the other people (IMHO), my problem with the calculator was due to several things NONE of which were the abilities of the calculator endowed by its creators. 1) It was the first HP calculator with the worst manuals and information. (I just two weeks ago for the first time found any purchaseable books on it. 2 Volumes on the GreatUnpublished site). 2) They didn't support it on both Mac & PC for updates (since I own a Mac, this was a problem for me). Especially considering that they actually expected people to update their OS and the calculators abilities in general. I don't want to go into everything, but I will mention one more. 3) They made all the flags and settings, way to mysterious, anonymous? Unless you knew an expert, or read this group and asked questions, you never found out anything about the calculator. A testiment to that is that the 49G still doesn't have its own newsgroup. I can't search anywhere and find books, etc.. solely for the 49g. There are tons of groups, books, etc. for the 48, but the 49 has been relegated to the unsupported section of life. It's as if when you purchase a HP49g you have purchased it new as someone elses return, and that you got it used with no manual because the person who returned it forgot to return the manual, and then the package states AS-IS, and you were told to be happy because you got some good price. (Not likely). I love the calculator, and will continue to use it. I just think this was a huge mistake on HP's part. The second mistake is getting out of the calculator market instead of fighting back and getting everything correct. -Anonymous ==== > Could an EE very knowledgeable about computer technology of the early > 90's,tell me if it was possible by the time of the HP48GX release,to > release a much more powerful calculator(with FPU,faster CPU,higher > resolution screen,more memory and memory expansions > possibilities,etc...) at the price of the HP48SX ?

Backward compatibility could have been achieved with use of a SATURN as co-processor just for this purpose a bit like the Playstation 2 uses a Playstation CPU as IO processor but also for backward compatibility.

I can tell you that the only thing that Sony did right with the PS2 was allow older games to be played on the PS2. Also, not because people want to do that. If they have the games they already have the machine. It was more of a great marketing ploy to convince people that is a benefit to them. They dropped their great single CPU + 1 gte (math coprocessor design), that were integrated together via programming as one instruction set pathway, into the same gargabe mistake that sega made with their saturn. Multiple processors that were not easily used together. Forgive me. I have been reading your stuff for a couple of years now, and have always thought of you as god like with the HP stuff. Especially the 49g. I just really think the PSX, PS2 analogy was really far off the mark. -Anonymous ==== > The HP48 GX has been released almost 5 years after the HP48SX letting > enough time to develop software for this newer architecture in higher > level language off course. > Backward compatibility could have been achieved with use of a SATURN > as co-processor just for this purpose a bit like the Playstation 2 > uses a Playstation CPU as IO processor but also for backward But if you're using two cpus how can you then achieve the same price as an HP48GX alone then ? You simply can't put two cpu like this on the same board, especially using let say a 32 bits CPU and a 4 bits one. The Saturn is one of the most expensive component (above $11). Otherwise, you don't seem to realize the job, I doubt 5 years is enough to achieve something as complete as the HP48GX Has anyone ever written a program (in VB, or whatever) that will take a UserRPL program and convert it to a SysRPL program? The reason I ask is because I just finished writing a program in UserRPL that calculates the rise and set times of the moon based on longitude, latitude and the date entered. The problem is that it takes 4 minutes to execute, so I must rewrite it in SysRPL. I've dabled in SysRPL and am fairly confident that I could rewrite it in SysRPL, but I'm looking for a better/faster way. That's when I thought of writing a program that will convert UserRPL to SysRPL because I'd be able to use it to convert other programs I've written also. I realize that in order for it to work in all cases (for all UserRPL commands) it would be a huge undertaking, but I could start small and write something for only the most popular commands, and structure the program so that it would be easy to add commands as they become necessary. Does this sound like a feasable idea? Or is it a pipe dream? Has anyone tried this before? - IR ==== In fact, every UserRPL program *is* a systemRPL program. Automatic translation is (I think) not possible because the translation should get rid of dispatching, and that is only possible if you know exactly what objects you have on the stack. This an automatic program cannot know. - Carsten S> Has anyone ever written a program (in VB, or whatever) that will S> take a UserRPL program and convert it to a SysRPL program?

This an automatic program cannot > know. How about this: You put the objects (and only the objects) the program will be able to take on the stack, plus the program on level one. The converter would then first look at the objects on the stack and add a suitable dispatcher, and second SST through the program, looking at the dispatchers of each command and adding the suitable subroutine. Just an innocent idea =) - Thomas -- Thomas Rast If you cannot convince them, confuse them. -- Harry S. Truman ==== > All young students in US will eventually become engineers of tommorow. No, but all engineers of tomorrow will come from young students of today. :-) ==== > Anybody has an dump of HP71 ROM? I want it only to play with Emu71 for DOS. Yes. I used an HP 82164A HP-IL to serial interface to hook it up to my PC, and a simple BASIC program using PEEK$ in a loop to read the ROM then print the strings over the serial. ==== I've finished the beta version of the rename library for the HP48G series. * Two commands, RENCMD and RESET. RENCMD takes two strings. On level two, the name of a built-in command (libs 2 and 171 so far) or an already renamed one. And on level one, the new name (1-12 chars). RESET restores the original command names. Required before purging. * If user flag 25 is set, then the assignments are preserved after a warmstart. * The library is self-modifying (hash tables need to be on stable addresses). * Parallel list processing is enabled, but slow. * Size: 10 Kb. And it needs about 10Kb of free mem to run! Some examples: SIN -> SEN MEM -> ROOM HOME -> HP48 MINEHUNT -> GAME EVAL -> RUN RUN -> PLAY ... All occurrences of old names are replaced: programs, most menus, review key... Old command names become valid id names. Bye.

(No overlays you see, old good HP41 :-() By the way, I tried to make some keyboard overlays for my HP49G by scaning the calc, printing the picture on thick paper and cutting of the scanned keys. It fits good, but the problem is that, as the shell of the HP49G is so much different than all the other HP calculators, the overlay is very easy to be removed. Actually almost any movement is enough to let the overlay fly away from the calculator. Has anybody any idea, how it could be made to stay on the keyboard a little bit more firmly?
