8444 === Subject: Re: Calculator defined Of course, when virtual machine is good, language is a matter of configuring the interpreter/compiler the right way. Therefore all languages you listed here would be possible obviously there would be 2 modes of operation : -interactive interpreter (for command line / user interface / file handling etc...) -compiler mode for running programs or compiling basically there would be 3 types of programs : -scripts (compiled and executed when called -stored as source code) -compiled (pre-compiled for short start-up time -stored as byte code executed by virtual machine) -native ARM (assemblies stored as binary -macine code executed directly by the processor bypassing the VM) The outline of virtual machine could be something like this : -memory handler (alloc, free, garbage, cpu-move, dma-move, dma-device) -display handler (framebuffer/blt operations alloc,free, scroll, zoom,rotate, drawing operations. pixel, line box, poly, text, fonts) -file handler (SD, 1 and 4 bit including dma transfer...) -keyboard handler (detecting keys, debouncing, keyboard state buffer, key queue) -timer (system timer-triger, RTC) -atom types (numbers 16,32,64 bit based binaries and BCD prefered over IEEE float...) -operators -tasks -flags ... handlers are actualy portions of VM which talk directly with hardware in your average everyday operating systems they would be called drivers these could be updated separately as long as they follow defined model. that way you could for example, plug your device to different display type update the display handler/driver and all would work again much like your everyday desktop OS. NOTE : -the VM iteslf could be a LOT like Saturn only this VM is both firmware (BIOS) and OS in one : meaning it talks directly with hardware no additional layers between them user <> application <> VM <> hardware instead of: user <> application <> emulator(VM) <> KOS(firmware) <> hardware nicer, smaller applications which takes care of more of users needs, which finally makes users happy :-) -these are just first few things in my mind i felt i should write down :-) manjo === Subject: Re: Calculator defined this is revolutional (no less than iPhone :-) everything is seen somwhere at some point in time, so it would be: -just like the good old days (very nice) -a bit refreshed and re-thinked (even better) manjo === Subject: Newbie question! Is there any chance to calculate and operate with logarithmic functions with different bases on HP50G. Adding, multiplying and similar, like on calculators vulgaris... :-) === Subject: Re: Newbie question! No, you can't specify log of 38 base 5 by default. There is probably a program for this, or you can easily make your own using the change-of- base formula. For example, to calculate the above log, just do log(38)/ log(5) or ln(38)/ln(5), but you probably already knew that. === Subject: Re: HP 35s Impressions reth schrieb im Newsbeitrag > [..] > For me HP35s is the first *HP* calculator after the HP48. > Full ACK! > I can live with its bugs, they are not critical. > Can't judge this so far, but normal calculations seem to work correctly... > 2.

Raymond === Subject: Battery life 49g+ Last week I couldn't power up the old 49g+. No reset of any sort would work. I changed the batteries and she sprung to life. There was no low system battery warning. So I changed both the ROM backup CR2032 battery and the AAAs. The CR2032 metered OK though. Eight days later while doing a backup, the low battery annunciator was flashing. I powered down and could not power up. Batteries were deader than a door nail. Again, no low system battery warning. I usually get at least 7 weeks from a set of batteries, and since my early days with the 48GX have never seen this. Is the 49g+ shot, or maybe the contacts need cleaning? === Subject: Re: Battery life 49g+ > Last week I couldn't power up the old 49g+.

Is the 49g+ shot, or maybe the contacts need cleaning? I wipe the contacts on batteries and case with dry cloth to remove the greasy-acidy fingerprints so that contacts are clean and reliable. scenario a) there was a ROM version which seamingly resolved keyboard problem (not entirely though) but sideffect was that it was battery eater -be sure to use the latest official ROM version. scenario b) sometimes one of the batteries may be deffective and die in few days of use that's what happened to me few times -the first time i hadly belived it. The other two were almost 90% when one of them died completely. scenario c) Battery life should be signifficantly greater than 8 days, but if your programs write to Flash (port 1 or 2) or SD (port 3) intensively or if you use IrDA or USB a lot it will burn your batteries a lot faster. note: it was not calculator, it was battery issue although expiration date was fine. i tried several brand of batteries, but as it seams (for me) duracell have decent lifetime and price (possibly the best) if it's none of the above then it's deffective :-) manjo P.S. The best way to do backup is to pull out the SD and make a backup on your PC using a card reader. Also copy (or keep) your data on SD from time to time -once every few days. (assuming you are using your calculator with set of tested programs and your favorite setup) of course if you use your calculator a lot, i sometimes use it so much that it gets warm underneath, you can't expect long battery life. === Subject: Re: HP 35S status? > So what is the current story for the HP 35S?

Harrison Looking on the HP web site yesterday it looks like they are again shipping, or at least accepting orders. If someone gets one of the new ones from HP it would be nice to know if they have improved the LCD cover for less reflectivity as the one on early units is bad in this respect.

I also wonder about precise battery voltage affecting current readings. I've used 48G's for serial transmission to Plotters, and recall readings around 16mA. Perhaps in the (not too distant) future I'll get a couple of the 48G's out and compare. TomCee === Subject: HP 50G AC Power Supply I just purchased a AC to 5V power supply for my 50G from Amazon. The one I chose is a Sonnet USB Power Adapter for iPod. It cost considerably more than many listed but did not have any customer feedback reporting DOA units as the cheaper ones did. The wrong type of failure on one of these could be fatal to the calculator. The wall transformer unit is extremely compact, with a folding AC plug for even more compact storage. It includes a LED on top which is green when the unit is powered on. This changes to amber when the calculator is attached and powered up, drawing current. The unit is rated to output 500ma, far more than the calculator should ever draw. I just used it to power the calculator while updating the firmware as the calculator arrived with down level firmware. It worked great. The unit does not include a USB cable compatible with the calculator so you need to use the cable included with the calculator or a similar one. I suspect similar power supplies should also be available at Best Buy, Circuit City and similar sources. Rich W Rich Wood
