But the Flash-based HP models Flash is used to store the core operating system, the Saturn emulator, and the Saturn ROM image. Additionally, all objects stored in bank 2 (\FLASH\) are stored in Flash. Otherwise, all other stored objects, using standby battery power (either the main AAA batteries, or the lithium backup batteries). - Luke === Subject: Re: Calculators using flash memory - lifetime? posting-account=v6m75AoAAAAgp3vyiLFAfyqmfMcXEPkm Gecko/2009042316 Firefox/3.0.10,gzip(gfe),gzip(gfe) I think flash memory is untouched unless you write/delete something there (ROM upgrade, install a new library, or write any other object to flash). The calculator does not write to flash for normal operation. No need to worry about that. === Subject: Re: Calculators using flash memory - lifetime? > I think flash memory is untouched unless you write/delete something > there (ROM upgrade, install a new library, or write any other object > to flash). > The calculator does not write to flash for normal operation. > No need to worry about that. Hmm, I can't speak for the HP 48/50, but the manual of the Casio 5800 says that the variables and program data are stored in the flash memory to be kept even if the battery is replaced. The manual doesn't mention any auxiliary battery. So the flash is actually used in normal operation, but the question is how often it is used. If only used on shutdown, then it might be ok (one may estimate how long it will take to switch the calculator on and off 100,000 times (the number of write cycles typically given ob web sites). If used 10 times a day with full memory (i.e. every flash bit used) on average then it would take about 27 years to kill the flash. Most, if not all, HDD drives die much earlier. -- Gru§, Ingo === Subject: RPN/RPL Calculator implementations, list of, regular post [long, \ FAQ] Supersedes: Last-Modified: 2009-06-12 Posting-Frequency: bi-monthly URL: http://www.finseth.com/rpnrpl.html Copyright: 2002-9 by Craig A.

Description This document provides a list of implementations of RPN, RPL, and HP calculators for other systems. You can help make it more comprehensive by sending me additional information and/or updates. To be included in this list, an implementation must: o implement at least a \standard\ 4-level RPN calculator. Minor variations (e.g., 3 or 5 levels) do not preclude being listed. Implementations that include both RPN and algebraic modes are eligible. o implement an RPL calculator. o implement a \clone\ (or near-clone) of any Hewlett-Packard calculator, even if it is an algebraic-only model. The following information is included for each implementation: Implementations are listed alphabetically by name. If the implementation emulates or approximates a specific calculator and it is not obvious from the name which calculator is emulated, the emulated calculator model is given in parentheses. The *LAST* *CHANGED/VERIFIED* line contains the date that the entry was last changed or an explict \looks ok to me\ was \ received by the FAQ maintainer. The *ORIGINAL* *DISTRIBUTION* is the date (or partial date) of the first release. It is in YYYY-MM-DD format. The *VERSION* is the latest known version. It is probably out of date. The *ENVIRONMENT* is the operating environment. This is a very high-level description: consult the documentation on the product for any specifics. The *ORGANIZATION* is the name of and contact information for the implementor or current maintainer. The *STATUS* is one of o no longer available: Self-explanatory. o free: The implementation is available to most people at no charge. Even such \free\ implementations may have \ restrictions: consult information about the particular implementation. Where available, information on how to obtain a copy is also listed. o shareware: Self-explanatory. o not free: The implementation is for sale. Contact the vendor for specifics. Many of the names of the implementations in this list are trademarked. Specific trademarks are not called out. The site http://www.hp41.org also has a list.

Both categories exist -- simulators having no original ROM at all, and emulators of original hardware with an original ROM; even in the latter case, one may wonder \which original ROM,\ because some products may have had original bugs that may have been fixed in a later ROM (though I don't know what versions may exist of the particular models listed above). If any product really contain an original ROM, then any self-test which happens to display a distinct ROM version on a real calculator should reveal which ROM was used. I believe that the following are only simulators, and may well not deliver the original results of the original products: XACT Calculators (Simulators of the HP-11C, HP-12C, and HP-16C for MS-DOS) http://www.hpcalc.org/details.php?id=3704 An HP12C simulator http://www.educalc.net/324080.page How do we know that the latter is a simulator, without even trying it? Because its \readme\ file says: There are some minor differences, especially with respect to the number of program lines. The [simulated] calculator always has 99 program lines available and all 20 storage registers available for storage and math operations [whereas the real calculator sacrifices some registers to get more program \ lines] Doesn't HP sometimes even re-issue an old calculator, in a model which doesn't even get the original right answers? Apparently that's also a simulation, only disguised to look like the real thing. To make sure that your 12C is the \real thing,\ see whether it has the additional command that was never mentioned in its manual, and the few authentic original bugs.

Different manufacturers do things different ways. stuff that rarely needs writing to, such as the machine's firmware, libraries etc. If you want further details about how the Casio fx-5800 does things then I suggest you ask in a more general newsgroup or in a Casio-specific one. comp.sys.hp48 is not the best place for that. === Subject: Re: AT&T dropping USENET > >> A lot of Usenet reading folks I know filter out anything posted from > > Then they will miss all of Joe Horn's postings :) Joe who? ;-) -- Bruce Horrocks Surrey England (bruce at scorecrow dot com) Subject: Re: AT&T dropping USENET > === >> Subject: AT&T Usenet Netnews Service Shutting Down Other ISPs have also cut costs by dropping services >which they don't believe to contribute to profit, >whether they have outsourced them or maintain them internally.

See: http://www.tdsway.com/support/knowledge base/survey pro/on the hp \ 48gx/general tips/KB704 Excerpt: The older cards had a replaceable battery that could be replaced once a year to keep a full current running through the card. These cards are no longer available that have a non-replaceable battery that must be charged in the 48GX to keep a full current running through the storage media. The 48GX must be turned on for the charging process to work. If your 48 is not used regularly, to maintain data integrity. This is the main cause of data loss. It only takes approximately 30 days of inactivity The following procedure can be used to set an alarm or just prior to use if the card has been inactive for some time. This procedure takes at least 24 hours to charge a card for use.

It's a CR2016 coin battery available just about anywhere in the US (Walmart, Radio Shack, etc...) To replace the battery, turn the 48GX ON and then turn it around making the port cover (the cover thingy on the top end of the calculator) easily accessible. Remove the cover so that you can now access the cards. The port 2 card will be the one on top of the other (port 1) card. In other words, the TDS card will be the card you see on top (my TDS card is a weird blue/green color - mold maybe? lol). The very tip of the card (next to the read/write switch) has a kind of lip that you can slip a fingernail under. Slip a fingernail under it and gently slide it away from you, toward the top of the calculator. The battery will be in a sort of 'C' shaped holder. Note the polarity. The + side will face the back of the calculator. Replace it with a fresh battery and slip it back into it's holder, then back into the card. The calculator must be ON during the entire process or you will lose everything in it.

I do try to keep the file names with the old DOS 8.3 format so I can tell what they are. I have the latest ROM update, and several libraries that I installed on my calc saved on my SD card.

Incorrect in this case. If you copy an HP directory to the SD card, it is not browseable because it is a single binary object. FAT directories, like in this case, work just fine. You can access them using things like 3:DIR1/DIR2/prog.hp EVAL just fine. I'd recommend that the card be checked for problems using CHKDSK if you are in windows. May be a problem on the partition itself. Also, I have seen problems on the HP if you give the SD card a name, like HP CARD, and then try to access a directory on the card named identically as HP CARD.

I do try to keep the file names with the old DOS 8.3 format so I can tell what they are. I have the latest ROM update, and several libraries that I installed on my calc saved on my SD card. I think I found the answer to my question. The forward and back arrow keys seem to let you look a files in a directory on the SD card when using the built in File Manager application. The view command lets you look at the files. Works for text and algebraic objects. Even lets you look a PDF file(Only theCODE) not the actual content as when using Adobe Reader,etc. I installed SDFILER1.3 an it recognizes the extended length filenames from Windows(Neat) In a related question to the authors of SDFILER 1.3. Does it have a view function like the native Filemanager Application? I also noticed that one can get 2 sort of text reader functions if one installs HeadMan9.

Incorrect in this case. If you copy an HP directory to the SD card, it is not browseable because it is a single binary object. FAT directories, like in this case, work just fine. You can access them using things like 3:DIR1/DIR2/prog.hp EVAL just fine. I'd recommend that the card be checked for problems using CHKDSK if you are in windows. May be a problem on the partition itself. Also, I have seen problems on the HP if you give the SD card a name, like HP CARD, and then try to access a directory on the card named identically as HP CARD.

I use Forte Agent? Google newsgroups is a slight misnomer. This newsgroup is not a Google newsgroup, but Google archives it, makes it available to read on its web interface, and will send any posts you make from its web interface back into the peer-to-peer networking system, otherwise consisting of servers of the type (NNTP) to which Forte Agent directly connects. Google also hosts private newsgroups which do not circulate in that same networking system, but this is not one of those, and the answer would still be no even in that case, because as far as I am aware, Google does not offer a directly accessible NNTP server to the public. > I do not like to use my browser for either EMail or newsgroups. Then you will need to re-direct Forte Agent to some other NNTP (news protocol) server than AT&T's, once AT&T pulls the plug on theirs.

This may not be the most optimized way to do it ( I'm sure someone out there with more experience can improve it ) but you may try something like the following, with the arguments X and Y already on the stack: DUP2 creates a duplicate set of arguments. Gamma swap Gamma * unrot evaluates the numerator and sends it to the bottom of the stack. The + eval Gamma takes care of the Gamma(X+Y) with the separate evaluation for the inner sum. The / eval finishes off the job by evaluating the ratio [Gamma(X)*Gamma(Y)] / [Gamma(X+Y)] . Using your example of X=1/2 and Y=3/2, I get the result Pi / 2 which is correct.

You can purge libraries using the built-in Filer. It takes care of both detaching and purging them. Just go to the port where you installed them (port 2 for Flash), select what you want to purge, press NXT until you see the PURGE label, then press PURGE. > I asked the question before about the need to or ability to > De-fragment Flash. What is actually happening > when I delete the old libraries and install new ones? Deleting any object from flash merely sets one byte, to indicate that the object is deleted, so that it will no longer be listed by the Filer or in port menus. The space occupied in flash continues, however, to be occupied, because it is not possible to overwrite in flash, except by erasing a whole bank and then starting anew to write in that bank, like a magic slate. Storing into flash always thus stores into a new physical area, until such time as there is no place to store something, at which time some automatic re-organization of one bank may occur, then the bank is completely erased, then the active objects are stored back, into contiguous locations, thus eliminating any previously purged items. > How are libraries added to Flash. Are they located in Flash like files > are on a Hard Drive when it is new, in long contiguous sections, or > all over the place as when a Hard Drive needs to be defragmented? Single objects must be stored whole. It doesn't matter how different objects are distributed within one flash bank, or among all the flash banks, and all of this detail remains hidden and transparent to the calculator user, unless you use external software which shows more detail. > Is the memory that was used by a deleted library somehow reallocated? Only when its original flash bank gets erased.

The files on the SD card, therefore, are outside of the environment of the calculator operating system, and can only be used for similar transfers; calculator libraries therefore can not function as libraries unless they are first transferred and installed to an internal port (0, 1, or 2). === Subject: Re: Deleting Libraries > I installed two libraries on my HP50G.

I thank you for your answer. As I said in my original post I have never been interested in the underlying processes that make my different HP calculators do what they do( Unless there is a bug that affects my work). For some reason( I do not know why) I has recently become interested in this subject. Unless your really get into the innards(Hardware and software) of an HP calculator you don't realize how truly amazing these devices are. I remember using both an IBM 360 Mainframe in the late 60's at Texas A&M and an IBM 1600 a few years later.. It is hard to realize sometimes that our little had held devices are more powerful in some cases than these big machines. Harold A Climer Dept.

Here is the way I do things: 1) I display KEYTIME value, and it shows 2; 2) I modify KEYTIME correctly (to 0 or even to 1); 3) I display KEYTIME, and it shows 2 (whatever I typed 0 or 1).

I've understood the underlying problem. In fact, when I modify this value, the ``new value'' is simply stocked in a var in the current directory, and does not modify the ``good'' variable. How can I manage to do this correctly, then? === Subject: Re: Putting subscripts in equations > It is a little bit disappointing, as there are > plenty of formulas where you need to put subscripts. A subscript is, in effect, when it comes to evaluating a formula, rather than just displaying text, either part of a variable name or an index of a list or array. You can therefore handle a subscript either by including it in a variable name, or as a list or array index, or as an argument to a function, each of which has been illustrated in previous posts. > Anyway, there are other issues: if for example, > you want to keep in the calculator's memory > something like an infinite sum (a series), > it does not want to memorize it, > as it results firstly in an overflow problem. I don't know any computer, however large, that can actually write out a complete infinite sum :) However, I do know of a summation function in the calculators, which takes as its arguments an index name, lower and upper index limits (accepting the infinity symbol as well), along with a formula to be invoked for each index value, e.g. 'GS(n=1,oo,2^-n)' which evaluates to 1 on HP49/50 CAS Also, after << -> n << X n R->I + S~N >>> 'V' STO then 0 1 3 FOR n 'V(n)' EVAL + NEXT evaluates to 'X1+X2+X3' On HP48 series, 'GS(n=1,3,V(n))' [with suitable S~N function] also produces 'X1+X2+X3' but on HP49/50 CAS it does not. === Subject: Re: Putting subscripts in equations > It is a little bit disappointing, as there are > plenty of formulas where you need to put subscripts.

Anyway, there are other issues: if for example, you want to keep in the calculator's memory something like an infinite sum (a serie), it does not want to memorize it, as it results firstly in an overflow problem.

That reminds me of a post three or four years ago on one of the Usenet space-program newsgroups. A rather naive user who was in awe of the Apollo hardware asked if a modern desktop computer had anywhere near the power of the computer they put in the Apollo service module and lunar module. The reply was that a modern desktop computer has more power than the computers at Mission Control, let alone the little ones in the spacecraft.

I thought it would be easy to insert some codes that would allow mixed fonts and therefore a sort-of subscript, but no go. Apparently the fonts have to be the same height. And the codes are just too awkward. If someone really, really wants subscripts, here's a way to do it, although the initial setup is time-consuming. I used the character editor in CHARS to create some half-height numbers and characters, overwriting some of the accented characters above #127. They aren't true subscripts since they don't descend below the baseline, but the appearance is adequate. Here's a screen shot: http://i150.photobucket.com/albums/s103/bmarkwick/fontsub.gif Some notes: - If you actually do this, your work is lost on the next warmstart. To make it permanent, use FONT-> to get the font object, then store it in the Home dir with your choice of name. In STARTUP, add the new name and ->FONT. - The sub becomes part of the variable name. For instance, if you have 'X^2+X' and you add a sub1 to the last X to get X1, X and X1 are now two different variables. - You can't start a term with a number followed by a character: for example, 8sub1 will cause a syntax error because the calculator is looking for an operator after the number. === Subject: How to see files in directory on SD card I have a 512 Meg SD card installed in my HP50G.
