Just thinking out loud here... That problem could be avoided like this: When the boot ROM image is transferred into the calculator, load it into an unused bank first. Then test it thoroughly to make sure it's an exact copy. Then, in a single operation, relocate the boot ROM pointer to *that* bank. Finally, clear the old boot ROM and merge it into the Port-2 pool. If the boot ROM location is hard-coded, then the above is just a pipe dream. But if the boot ROM is relocatable, the above seems like a good way to upgrade the boot ROM without danger of killing the calculator. -Joe- ==== Now that I think of it, you're right: a discontinued > bootloader load would kill the bootloader thus the > calc cannot load anything anymore.

I don't have it handy, but this has been answered on comp.sys.hp48 in the last 2 months. If you do a google search, it should turn up. In the HP49g+ training aids on HP's website, there is an example that shows how to plot a vertical sine curve. This would be done similarly to what you want.

I'm afraid I don't know anything more about this. 2) Attach the HP49G+ and switch on. 3) Type (on computer): dmesg to see what's going on. There should be a line at the end similar to usbserial.c: Generic converter now attached to ttyUSB0 (or usb/tts/0 for devfs). This is saying the calculator is connected to /dev/ttyUSB0. 4) Run kermit (on computer): I have to do this as root to access the port correctly, but this may just be my being too lazy to sort it out! If you don't have kermit, binaries are at http://www.columbia.edu/kermit/ck80binaries.html 5) Follow the instructions at http://lcdx00.wm.lc.ehu.es/~svet/hp49g.html. Note: a) When this page says, 'HP49G: Set the calculator to server mode pressing right shift and right arrow,' it means press them simultaneously so that one is using kermit, not xserver. b) The set port instruction should, of course point to the port listed above: /dev/ttyUSB0 or whatever dmesg reported. c) Also, you may not have to use robust if safe_serial is loaded: I don't know about this. Anyone have any comments? 6) That's it. 6.5) Ah, except that my system has a bug which causes a crash in usb_serial, if the calc. is disconnected whilst it's loaded. I get round this by quitting kermit, doing a rmmod usb_serial and _then_ unplugging/switching off the calc. Sorry if this is overly simplistic, but it seemed worth setting out. If anything here is particularly stupid then please post to say so (politely!): I haven't spent any real time investigating this, beyond getting to the point where I can still avoid ever booting Windows.

The difference I made was the following: - the dot product is the function (x,y),(x',y') -> x.x' + y.y' (if dimension = 2), and it depends on the basis you are considering. - an inner product is a positive definite bilinear form. For each inner product, there are basis in which it is the dot product, in the case of real vector spaces. The dot product, as defined above, is not positive for complex vector spaces.

I ended up returning the calculators anyway, but there were definitely real, live, people to correspond with. That said, I am STILL miffed about getting two defective calculators and having to pay for shipping three times! I told them that I wouldn't purchase another 49G+ unless they would guarantee me that I wouldn't be out any more money in case the third is defective as well. Nobody was willing to do that; I am using my old 48GX.

How do I know HP has fixed the issue? Don't you guys read this NG? You need to grab a button between you thumb and index finger push the key down and move it from dide to side about twenty times Then it should register on every click. Worked on my keyboard... 9888 ==== I plagerized this code << “Enter a: “ {“ :a: “ differently from the PROMPT command, and what function does the {2 0} V serve??? ==== Actual string should read as follows: This prompts for input. How does this function differ from the PROMPT command, and what function does the {2 0} V} serve??? ==== INPUT Command uses V as to Verify the input as you would type it into the command line eg. not just a text string, but a valid object. { 2 0 } specify the tabulator fields where you input goes. Experiment a bit, and if it doesn't open up, call again. :-D ==== would teach me secrets like this? Or do I just need to read the manuals that come with the computer. I cannot find reference to this V verify code anywhere. ==== The HP48 Advanced users Manual (Printed version) has this and a lot of other goodies that are valid for the 49, and are not easily found elsewhere. But my copy is guarded by rabid pit bulls. ==== Take a look at this *HUGE* PDF: (HP 48G Series User's Guide) http://ca-on.hpcalc.org/details.php?id=3937 ==== HP48G Series AUR, or some similar user-written document at www.hpcalc.org, or Appendix G of HP48G Series User's Guide (also at hpcalc), or Donnelly's HP48 Handbook (out of print).

(Given below if you want it) No problems so far - the result was 128.35*EXP(0.0585x) (rounded off). The strange result came when I tried to use PREDX. Entering PREDX(150) gave the result below: (-2.67319970364E-2+(0,6.28318530718)*n1)/-.782404601086 What gives? Even if you eliminate the complex portion and use -2.673E-2/-.782 you don't get the correct answer of x=2.66 Year (yrs after 1975) 0 5 10 15 20 25 Pop.
