I agree that it would have been easier to *convert*, but I think the SASM syntax is easier to read on the PC, especially when there's a (useful!) comment on every other line or so.

Blocks is one example where you can use space or not with no differences on MASD, but not in the HPTools. For example: ?A=C.A -> { ?A=C.B { }} Is valid on the HP49 but not valid with the hptools for 2 reasons: -> must be immediately followed by { (no space in between) and }} will fail on the hptools, it must be } } (with spaces in between) There are also a lot of macro that works on the HP49 but not with the hptools, like RES.STR Last but not least, MASD will perform calculation on 64 bits, while the Hptools only support 32 bits.

I don't understand what you're trying to say. The issue (admittedly off-topic for the group) is whether or not DST has an advantage. In the UK it does have an advantage: it saves lives because people can *see* each other during crucial times of the day, and specifically children going to school can be seen. Shifting the time by an hour on a seasonal basis turns out to be quite a good fix for this. You can easily go and look this up - look in Hansard (the records of the UK parliament) or somewhere. If you think there is some other, better solution (which isn't `install huge great lights in the sky' or `stop people driving at night' or something equally stupid), then suggest one, I'm sure people would love to know it. --tim ==== Maybe we should have Winter Time & shift clocks the other way during mid-winter > If children get killed, it has nothing to do with Daylight > > savings.

With a grading program, a teacher would not have to go back over their roll book to average a student grade.

You will get 'X=2/(Y-1)' on the stack. ==== You know 5. to 5? Do you use IP? thanks. Kevin ==== > You know 5. to 5? Do you use IP? thanks. Kevin There are several ways. R->I, which only works on approximate mode integers. On other input, it produces an error. (I->R is the reverse operation). ->Q, or XQ, both convert approximate expressions to exact expressions, AND both set exact mode. When applied to an approximate mode integer they will produce an exact mode integer. XQ will also recognize and convert to certain rational multiples of pi. ->Qpi, where pi represents the pi symbol, acts like XQ except that it does not change the exact/approximate mode setting. All of ->Q, XQ and ->Qpi will recognize decimal forms of certain simple square root expressions and convert to them, and can be applied to expressions containing names as well as numbers. The conversions made by these last 3 commands are also affected by the display settings for approximate numbers. ==== Has anyone had success in using a custom menu in the 49G equation writer?

Well, sure, you could do that. So everyone would have to remember that stuff that happened at, say, 10 in the summer happened at 11 in the winter. You'd need two copies of any kind of schedule, shops would need varying opening hours, and so on and so on.

However, the last time that I was there, part of Indiana observed Daylight Saving Time, and part didn't; a bit confusing for visitors. And of course, when dealing with someone who does observe Daylight Saving Time, you're forced to adjust to them messing around with their clocks twice each year. Here in Michigan, the situation is, in a way, even worse. Most the state, especially if we ignore the water (parts of Lake Huron and the St. Clair River), should be in the Central Time Zone, but we're actually in the Eastern Time Zone, and we observe Daylight Saving Time, pushing us even further from Local Mean Solar Time. I wouldn't mind the least bit being in a different time zone from New York, and I don't think that many would find it all that strange to be in a different time zone from Ontario. > It is great one day of the year when you have to wake up very early on a > Sunday morning to do a triathlon.

The feeling of discovering that you can > sleep one more hour: Priceless But wouldn't that day come in autumn? Around here, the saying is spring forward; fall back. I detest getting out of bed before the sun has risen. For anyone who has to go to work or school on the day shift, this is often the case during the first and last parts of Daylight Saving Time. Closer to the summer solstice, the sun will already have long been up when the alarm clock goes off, but then there's the problem of it being light far into the evening; have you ever tried to convince little ones (or not so little ones, for that matter) that it's time for sleep when it's still light outside? To me, it feels as if I'm being deprived of one hour of each night from the first Sunday in April to the last Sunday in October. It seems to me that I've read that the accident rate goes up after advancing the clocks in spring. If we really can't resist the urge to change the clocks twice each year, it would make more sense to advance them in the fall and set them back to Standard Time in the spring. That way we'd have more days when we wouldn't have to get up and drive to work, or for school kids, wait for the bus or walk to school, in the dark. I don't believe that Daylight Saving Time has ever had much effect on energy use. Leaving lights off in the evening is offset by turning them on in the morning, and in most cases, indoor lights are on whenever people are active, regardless of what the clock says. Furthermore, in an industrial society, lighting is, I suppose, a relatively small part of energy use. By the way, there are programs for calculating sunrise and sunset times on hpcalc.org and on Joe Horn's Goodies Disks. I suspect that they were all written for the 48SX, but should work on other RPL calculators with little or no change. -- James ==== > > I makes more sense to me to change the time that things are at than to > > change the time.

Locally, the school district has a one-hour late start (for students) most Wednesdays, so the teachers can have their meetings, training, or whatever during that time. It does indeed cause scheduling problems for parents, but it seems that keeping things convenient for teachers has priority over everyone else's convenience. Strangely enough, I once worked for a company that adjusted its schedule to do everything earlier during the summer, in addition to being on Daylight Saving Time. It's as if some people just can't stand the idea of the sun being up before they are. If it were up to me, we'd stay on Standard Time and keep the schedules the same year-round. -- James ==== James M. Prange schrieb im Newsbeitrag In general, a given time needs a definition, otherwise a given time is nothing, because it is relative. A definition contains the time zone and if DST is applied or not. The above mentioned information is not given on HP-calculators. By the way Willhelm Gates and his employes understood and have tried (partly successfull) to implement time zones and DST in their software ;-) HP-calcs: It is assumed, the user knows, which definition is valid for the system clock. All users who are not traveling, and those who are familiar with politic adjustments are fine. To confuse the users the definiation is changing from time to time, to make things easier... :-( > By the way, there are programs for calculating sunrise and sunset times > on hpcalc.org and on Joe Horn's Goodies Disks. I suspect that they were > all written for the 48SX, but should work on other RPL calculators with > little or no change. I have written a programm for the HP49G ROM1.19-6. It is written with german comments and documentation, available under http://users.belgacom.net/EAA/Heiko/index.htm see under HP49G. It is easy to rewrite the comments to english, make a draft translation... At the moment, the package in 98 % usrRPN is a little large (20 kByte), due to accurate moon-calculations and a sun-compass which should be dispensible, I think. I could reduce it to about 7 kByte, having sun rise, meridian and set with different twilight definitions (astronomical, nautical and civil twylight), working all around the planet. I would need some support for the translation, improvements and for testing. If somebody is interested to take part for the development, he should contcact me. Best wishes Heiko PS: DST: For me DST is only confusing. Consequently we would need only one standardisized time and this has already been introduced. I am talking about UT (Universal T) or winter on the suthern part when we have summer on the northern part of the earth. Why canot wake up at 3 pm and fall asleep 15 hrs later. Because most of us are not flexible :-) When you are traviling arround the earth, you prefer to ask for the clockadjustment, instead of asking, at which time the sun is at the meridian (south or north). If you are thinking world wide, time zones and DST are only confusing, because they are unsteady changes for different locations and times... The time beeing, we need to live with the unconvinient solutions, the poleticians have given us.

Now that I've looked into it a little more, I see that although Indiana should be in the Central Time Zone, most of it's in the Eastern Time Zone and doesn't observe Daylight Saving Time, but a few of the counties that are in the Eastern Time Zone do observe Daylight Saving Time, and some counties are in the Central Time Zone and also observe Daylight Saving Time. I'm glad that I've got that straight in my head; If I ever go there again, I'll look at a clock or ask a local (and hope that he's not from a different county). > Here in Michigan, the situation is, in a way, even worse.

But the four counties on the Wisconsin border are in the Central Time Zone.

However, there are several disadvantages I see: 1. There is even less information about engineering expansion cards than there is about books. I have looked at Usenet archives and can find almost no information on non-ram expansion cards (with the anyway?). If anyone has any opinion on PP (Pocket Professional) cards based on experience, I would really like to talk to them. 2. I am more interested in the process. A specific PP card would limit me to one type of engineering, whereas a book on engineering in general would give me insights into how the gx can most efficiently be used to solve engineering problems. 3. Generally, (and I have not looked into this with respect to expansion cards), software and hardware are harder to return. If I don't like a book, returning it is a simple process. 4. The software expansion cards are rather expensive, and take up slot that I am planning on using on RAM. preemtively or aggresively. I am certainly open the the thought.

After getting transferred to the wrong dept finally got over to calc service. I explained my problem with the tech on duty and she got the serial number and said that the reason for the calculator not powering on is static buildup if you carry it across the room and that a charge can build up on the case. I explained to her that I've heard that a capacitor was the cause of this in some calcs that were made in china. (Mine is) She said she heard of no issue with this. Three possible fixes were provided by her 1. leave the battery out for 24hrs and put them back in. 2. Send in receipt and if the calc is purchased within a year they would replace it with a new calc less book and cables. ( I explained that I sent in the warranty registration. She said that goes to another location and they have no access to that.) 3. Pay for a repair/replacement. She also said their whole line is affected by static and you have to take the batteries out. I told her that I have a HP32SII and a HP15C with no such problem. So I feel that i'm back to square one and that support did not help or was not willing to. replacing the cap. I can do that myself.

The oversizing is intentional, and I have a factor inside that drives the magnification throught the whole of GUI. It's still a bit of work left to reconcile the points (used for the fonts) and the pixels (used elswhere, at least theoretically), but we're going to do that eventually. The ENTER problem I'm well aware of. In fact, the original button fonts were a little smaller to make ENTER look better, but then all other buttons were looking not so great: letters were just a bit smallish when compared to the real thing. The problem there is that Swing doesn't seem to have any facility for putting in a vertically aligned text inside the buttons. Hence I had to hack around there quite a bit to get it done somehow, which is still not perfect, I agree. The yellow lines I'm working on. Currently they are just letters of that same font which come either good or bad depending on the system settings, and there's also a bit of alignment problems involved, but one can think of doing that right in graphics mode, so to say. However, we're going to introduce a photorealistic GUI any time now, which should resolve all of the above problems at the cost of even longer download time (sigh). But we'd really want to get the guts right first, you know, and this is what occupies the bulk of my time at the moment.

It would be very nice of you to give it another try (http://home.foni.net/~supalov/hp16c) and let me know the results. For the technically minded, there are three ways of embedding Java plugin applets into HTML (namely, the OBJECT, EMBED, and extended APPLET tags), and I'd like to learn whether the two officially suggested by Sun do work across the board. Currently, the OBJECT (IE) is in there, so browsers that are compatible with it should work. I don't like the COMMENT tag Sun's applet converter put around the EMBED construct, though, so the Netscape may have its problems, as it does on my CDE desktop. Browsers relying on the extended APPLET tag definitely won't work, for I had to remove it for now because it sometimes takes precedence over the two above, forcing the browser's own Java VM to kick in, which is most of the time exactly what one would like to avoid. Perhaps, I'll have to make another iteration or two before everything is need it because portability was apparently not Sun's primary concern in this case, the documentation is really crappy and incomplete, and I don't have all those environments handy to test it all everywhere. I'll also have a look around to make sure I understand those pages that do work as expected. Stay tuned - and please click once and let me know what OS, what browser, and what Java did or didn't work for you now. I'll really appreciate it.

Good news, the applet now works in Opera. I had to choose the one that said, This window uses the APPLET tag preferred by the rest of the world.. It seems to work great emulation wise; I haven't tried all the functions, but the simple ones seem to work. A few things to consider: the ENTER key is a little bit cramped, the calculator looks much too big in 800x600 (have to scroll to use all of it) and it would be intuitive if it had keyboard support, at least for entering the numbers and the four basic operations. Otherwise, it's looking good. Well done to you and your students! Albert ==== Only problem is that the labels above the buttons are partially obscured - the letters seem to have lost the top pixel row. Also, the ON label on the ON-button is partially obscured, but in this case it's the bottom pixel row. /Lennart I've updated my HP-16C page once again to, first, use the latest and > greatest of the automatic browser recognition proposed by Sun, and, > second, provide those who use browsers that cannot be recognized > automatically a way to try out all three HTML tags (the OBJECT, EMBED, and > APPLET) separately.

The lower pixel line of the ON is not perfect on my screen either, so I'll probably have to decrease the font size - which will accidentally ease up the ENTER alignment as well. The upper pixel line will be treated the same way. Stay tuned - and thanks for feedback. Just to make sure: the main window worked for you automatically, didn't it?

Most of the upper echelon love her ideas and plans. However on the smaller scale of calculator production (or any widget's of any sort), she would rather outsource and rely on becoming more like Microsoft. Sell intelectial ideas and software, not widgets (ie calculators), is the new HP way. skeptical, why are you so sure? My own theory (and that's all I have ever had) is that Hp is designing and developing RPN calculators. But the pe'on engineers will not get these calculators into production as the RPN feature will add $2-3 to the production costs. This will be unacceptable to Marketing guru's who just know that will put their new $22 calculator up to $30 (US)and out of the market and unsellable. Therefore, it WON'T happen. You and I (and Bill Hewlett) may actually know better, but Marketers have their own information to the contrary (wrong and $#$#%UP as it may be). Hp has a terrible habit of castorating (sp?) its product lines, so as to not rob higher product lines. Not that Hp is alone in this practice, but I feel it is better to sell two Hp49G's at $120 that sell three or four Hp 39/40G's at $70.

Please help me. ==== > Iam trying to find out about how to use input command. > I keep getting an 'Input Error:Too Few Arguments'or I get 'Syntax Error'. Here's the basic Input syntax: Title String {:Label1: value value is any default, or just omit it. :Label2: value optional second label and value :Label3: value optional third label and value ALG V {Row Col}} INPUT If you don't want a title at the top, put a null string (). Don't omit the colons before and after the labels or you'll get Syntax Error. ALG sets algebraic entry and V is Verify (ie, check syntax). Without the V, you can enter pretty much anything, but it'll cause problems later. The Row-Col list sets the cursor position on startup. The output of the INPUT command is a string, which you then split with OBJ-> and process however you want it. Bill Toronto, Canada ==== I like those brainstroming about hardware design..

PCMCIA cards are huge, and the space they would take up is better used for other stuff IMNSHO. With two SD/MMC slots, you could use one for a flash card (up to 1GB now available), and one for I/O (modem, ethernet, 802.11b wireless, etc.) SD/MMC will take up less room than CF, and having two slots of the same type seems like a win compared to two different slots. There's even a combination flash/802.11b SD card now. ==== I like it! It's a real eye catcher, and it looks comfortable. If this calculator was nothing more than an HP49 with a bigger screen and a touchpad, I would still buy it. I would change three things: The position of the power button would probably cause me to unintentionally turn the calculator on. I would rather have it under the cover, that way it's me proof. I would also extend the left side of the screen cover so it covers the left-most keys as well. Once again, it has to be durable or I'm going to break it. Lastly, I could see myself trying to rest my hand on the keys while using the touchpad. I would either make the keys hard to press (like the 49) or switch places. I wouldn't be as likely to want to rest my hand on the touchpad as I would the keyboard. I also probably wouldn't be using the stylus on the keyboard. Way cool! --CS ==== Good design. May I suggest keys like on HP 48 serie or HP 41 serie. More precisely hinged keys that provide a good tactile feedback and that also protrude somewhat over the top plate of the calculator. That kind of keys act like a target for the fingers and makes for real fast keyboard entry. Make them injection molded for durability. The vertical format is a must, IMHO, for a handheld design since it conform well to the human hand. For desktop use it is less important. Of course, RPN must be part of a new design and, PLEASE, revert back to the wide ENTER key which is the heart of RPN. After all, the RETURN or ENTER keys are always larger on computer keyboards. I think it is difficult to please everyone. The functionality that will suit an engineer might not suits a student in maths. Or a carpenter might ask for functions that are irrelevant to a finance expert. That why a programmable machine with a solid base of function comes handy. But it must be easy to program or there should be a lot of programs available for it. One machine, in the past, had all that after only a few years of existence. The HP 41C serie. Some will remember the keyborad overlays, the assignable keys. The hundreds of programs available in the form of Solution Books, the thousands of programs available through HP (catalogs of contributed programs). All this started with the HP-65, was expanded with the HP-67/97 and later available and expanded even more on the 41 which could read HP-67/97 cards. Now, instead of trying to design a new machine from scratch or get inspiration from an existing machine with problems like the 49G, why not also use the good ideas from the past. Imagine a machine based on the 41CX with a larger screen and a powerfull, but easy to manage, programming language. With a lot of memory. Expandable. Easy to connect to external device (USB or fire-wire or ...). This could be a 49GX+. HP did it somewhat with the HP48. The 48SX I bough as soon as it got on the market was a nice machine with a good keyboard. Too bad it was stolen from me. The 49G is a good machine with a decent screen but with a bad keyboard that actually slows me down when doing pure number crunching. I know there are lots of programs for it but never as much as there was for the HP 41. It is a good idea that HP is involving students in calculator design. But they should also involve peoples working in some other fields which are heavy users of calculators. I leave it to you to establish the list. Of course, dont go overboard and have a list with dozens of fields. Then, HP could see the functionalities that occurs most often and make these as part of the basis of the machine. Then add less used functionnalities available through user keyborads or alternate keyboards definitions or menu systems. Then offer very specialized functionnalities as ROM cards, modules or downloadable programs or specialized peripherals. The only holdback is that it imply a design that should last for a least a few years to be worthwhile. The HP-41 started in 1979 and lasted for a decade or so. With today's tendency of built in obsolescence it is not financially appealing. I remember that computers where made to last, and lasted easily, five years and more in the beginning of the 80s. Then, in the 90s, they were obsolete after three years even if they could last for much more than that. Then, in 2000, they were outdated in less than two years. Today, you go out of the computer store with the brand new top of the line gizmo and you cross the delivery guy coming with a crate full of the even newer super top of the line Hyper Gizmo. Your ne machine is already outdated. I still have a functionning HP-45 and HP-41CX. What are they worth ? A lot to me since they work and they do what I ask them to do. My 49G is not too oudated since I upgraded to 1.18. Then I need to upgrade to 1.19-6. Then what ? All I ask is a machine that will perform what I need, efficiently and offer a decent durability. In the 70s I paid a lot for the 45. I paid for a machine built to outlast me. Do people want that ? Some, maybe, but the vast majority (I am talking in general, not only about calculator users) want to have the latest technology. Then, why build a solid machine since, anyway, it will be dumped after only a few years, if not a few months of use. Look at what is happening with VCRs, DVDs, Cam Corders, Digital Cameras, Cars, name it. That is why I doubd that HP will invest in a super versatile calculator. They would have to sell it for too high a price. It makes more sense to offer machines geared toward each speciality. What is still needed, however, is a programmable high end machine which can be connected to peripherals like printers, external disk drives and also to other calculators, PDAs, computers, cell phones (usefull to download names and phone number database). The 49 is near that. I lacks some connectivity and the keyboard is not efficient. The programmability is there but it is inefficient to punch thousands of keystokes on that inefficient keyboard to develop programs. At least we can use a computer and download the program to the calc. Lets hope that HP recover the spirit they had in the 70s when they invented the HP-35. Lets hope they refrain to try to pack every possible function in one machine. Lets hope they refrain to make it to appeal to only a part of its customer by using sahpes and colors that follows fashion trends. Lets hope they use top materials to insure reliability. Lets hope they provide expandability in order to keep it for at least 10 years before having to buy another. Then I might go in retirement where all this will not matter that much. Just ideas.

And they do, and will forever, long after their good HP bodies and keyboards die. Emulators!!! My new Pocket PC (Dell Axim) is running at a tap a fully stuffed HP-41CX or HP-49G -- for simple math I like using the HP-41, but for units and other complex thing the HP-49 is awesome! The HP-49G port to Pocket PC is not freeware. But the following are freeware (GNU): http://www.hpcalc.org/details.php?id=3644 (emulates HP49G, HP48, HP39/40, HP38G) and http://www.hp41.org/Emulation.html (emulates HP-41C, CV, CX and can add 4 to 8 plug in ROMs) These emulators are near perfect, and run all the programs I have written and collected over the years. And run them faster. And through the KML keyboard mapping you can create your own keyboard for these wonderful calculators!!! You define a new skin/layout and vola! You have a new calculator design. Via a touch screen of a PDA you can have a truly dynamic keyboard. Good luck!

The differences in the versions and revisions are in the operating system code stored in flash memory (ROM, although it's not exactly Read Only; you can re-flash it, with the exception of one bank used for storing the code needed to re-flash the rest of it), not in the hardware. Any version/revision can be used on any 49G. Some units (I believe those manufactured earlier than serial ID94...) have a problem with the I/O hardware, which could cause a problem with connections, particularly if the hardware on the other device is less than ideal. But note that I don't have any problems with Kermit and XModem transfers between two units with serials ID93... (or to my PC or 48 series calculators, for that matter). If you do run into a problem with this, I suppose that it wouldn't hurt to try to get a replacement from HP, or if you can't, search on: http://www.hpcalc.org/ for instructions for fixing it yourself. There have been several reports of Chinese manufactured units (serials CN...) with defective capacitors. Search the newsgroup archive at: http://groups.google.com/advanced_group_search?group=comp.sys.hp48 for more information on this problem. And of course there have been some more or less cosmetic changes, such as the material used for the display cover and in the keyboard feel. HP. The last (and presumably best) release of the commercial version is Revision #1.18; HP apparently decided that it was good enough and abandoned any further development. This revision should be available on HP's web site and at: http://www.hpcalc.org/ release is Revision #1.19-6. This revision is available at: http://etud.epita.fr:8000/~avenar_j/hp/49.html and at hpcalc.org. Revision #1.19-7 hasn't been released yet. I think that it's safe to say that most of us are hoping that JYA will release it soon. Maybe there are still copyright issues to sort out with HP? I believe that you can also find many of the older revisions at hpcalc.org. The consensus seems to be that revision 1.19-6 is indeed the best and most stable available. Consider the Beta to mean unofficial more than experimental. Assuming that you have a cable available for connecting to your PC, upgrading the flash isn't difficult, just be sure to follow the instructions carefully. I highly recommend upgrading to 1.19-6. If you try for any official support from HP, they'll no doubt tell you very helpful anyway; I think that you're much better off asking for help on this newsgroup. -- James ==== > I have three HP 49Gs as follows: > All three calculators have the following settings: X I think Urroz had ROM 1.16 in his calculator???

No, but it's easy to make the HP48 perform the cleanup. Way back in It's called HP42S and can be found on Goodies Disk #1. It can also be found below, for your convenience. If you don't have the required library (TLLIB by Jim Donnelly), you can use any other utility that performs global search and replace on strings; just replace the REPLACE command in the program with your favorite equivalent... even one written in User RPL if you need a mini- challenge. ;-) Hope this helps! -Joe- ----- begin HP42S.DOC ----- So ya wanna run HP-42 programs on yer 48, do ya? Piece o' cake! HP42S by Joseph K. Horn 15 Oct 1990 An HP-42-to-48/41-Emulator translator Files: The HP42S directory contains two files: TR42 and TAB42. Requirements: HP-42S, HP-48SX 41CV Emulator Card, and James Donnelly's Tool Library (for the REPLACE function). Purpose: Allows you to run HP-42S programs on the HP 48SX. Method: Print the program from the 42 to the 48, translate it into 41 code using the TR42 program, and run it using the 41 Emulator Card. Theory: The 41 Emulator Card allows HP-41 programs to run on the HP 48S. So it would seem that it should be able to run HP-42 programs too, since the 42 is so much like the 41. But it can't, because so many functions got renamed in the 42. For example, the CHS function in the 41 was renamed to +/- in the 42. There were so many changes, that Zengrange decided that the extra code required to handle the 42 was not worth the bother, especially since the 42 does not have external program storage ability, which makes the demand for 42->48 ability minimal. All we have to do, though, is replace the new command names with the old ones, plus a little minor reformatting, and the Emulator will think it's a 41 program. This editing process can be automatically & quickly done by running TR42. INSTRUCTIONS: (1) On the HP-42, execute 0 DELAY. (2) Get the 42 and 48 ready for I/R transfer: (a) Elevate the 42 by resting it on top of Donnelly's manual for the Programmer's Toolkit (it's just the right height). (b) Point them head to head with their HEWLETTs directly across from each other. (c) On the 42, press PRP. Don't press the program name yet, but make sure it's in the menu. (3) Transfer the program from the 42 to the 48: (a) Press INPRT on the 48. (b) Within 10 seconds, press the program name on the 42. (4) When transfer is done, see the program as a string in level 2 and a 1 or 0 in level 1. If 0, try the transfer again. If 1, it may have been a good transfer; attempt translation now: with the program string in level 1, execute TR42. (5) Check the result by down-arrowing through it. Q. What does TR42 do? A. It: (a) removes the unnecessary program line 00; (b) replaces all CHR 4's (printer linefeeds) with CHR 10's (newline characters); (c) replaces all double quotes with single quotes (for Emulator); (d) removes all unnecessary ST's in stack-register commands; (e) removes all those blobs on LBL lines; (f) changes the 42's special multiplication symbol into *; (g) changes the 42's special division symbol into /; and (h) replaces all 42 commands with their 41 equivalent, as listed on pages 171-172 of the 42 Owner's Manual. For example, all occurrences of +/- get replaced by CHS. There are 20 commands which are searched for and replaced. Q. How fast does TR42 run? A. Several seconds for a small program; several more for a large one. This speed is possible due to the use of the REPLACE function in the HP 48 Programmer's ToolKit by James Donnelly. Q. I don't own the 41 Emulator Card; is TR42 of any use to me? A. Yes; it takes INPRT strings, which are not really editable, and makes them useable. Q. What does TR42 do with 42 commands that have no 41 equivalent? A. Nothing. They are left alone so that you may create your own 41 Emulator command extensions (see manual) to emulate them, if you wish. Otherwise, programs containing such commands (like AGRAPH) cannot be run by the Emulator. Q. What do I do with the program string that TR42 yields? A. Whatever you please. You can EDIT it. You can PR1 it. You can STO it. You can ->41 it. You can even DROP it. Q. Can the list of functions that are searched for and replaced be changed? A. Yes, very easily. The file TAB42 is a lookup table of pairs of 42/41 commands. For example, the first pair is { +/- CHS }. You may easily add pairs or delete pairs from this list, and TR42 will be happy to use your customized TAB42. Q. In that case, can TR42 be used as a generic global search and replace engine? A. No, due to the other 42-specific work that it does. Joseph K.

Not on the 42S (AFAIK), but on the 48 end, you can use string-handling commands such as SUB and REPL on the string received. The non-printing chars that you get are actually printer control sequences. For example, if the alpha register contains TEST and flags 12 and 13 are clear, the PRA command outputs the string 027.9fTEST004 where 027 is the escape char (NUM code 27). The first two chars mean use normal-width chars, and the last char (code 4) means print line and leave print head at right. Since the newline char on the 48 is char 10, you should replace all occurrences of char 4 with char 10. Remember to execute PROFF once you have finished printing things. ;-) HPCC #1046 ==== Oops - I overlooked Joe's reply. Sorry for my clone. Jordi. -- ==== What is a good way to do this?

I'm afraid the engineering problems don't get easier by using either calculator;-). Both, TI and HP offer some great (and also not some great) graphing calcs. The TI89, the HP48G/GX and HP49G are all very powerfull calculators. It's realy more about what you like than what's better. I do own all of this three calcs but hardly use anything else than the HP49G. So in the end it's your personal choice.

Do you have any idea of the real speed versus the emulator speed? If the real speed is approx the same as the emulator speed, then it's probably a good competitor to the TI89/92 and HP49.

Even HP's 49 docs have some kind of indexing. I ordered and recieved the paper copies. It took about two weeks. They are VERY informative books, but don't expect them to be well made or well edited. One of my pages fell out and I'm finding spelling errors. There's a few mistakes, but they're fairly easy to sort out. I thought it was cool that they gave me the electronic version to tide me over until I got the hard-copy. Very good books.

It seems that I had better luck than some. I ordered both books and was able to download the PDF versions as soon as I paid, and the hard-copies arrived in a reasonable time. But the books had pagination errors; trivial in Volume 2, but bad enough to make much of the index pretty much unusable in Volume 1. They refused to take any responsibility for the pagination errors, (perhaps rightly) putting all of the blame on the author. Eventually the pagination errors in Volume 1 were fixed, and I was allowed a free download of the PDF copy. But I'm stuck with the hard-copy with the errors; it seems that the only way to get a replacement is to buy a new one (or print it myself from the PDF file). Later, I found out that my PDF copies could no longer be opened; seems that they were past the expiration date. I got to download new ones to replace them, so they did make good on it, but it was an extra hassle. Note that they don't necessarily do the proofreading and editing and so on that you'd ordinarily expect of a publisher. They obviously didn't for these books.

Bill alternate E-dress wtstorey@ieee.org.no.spam.please (Use the obvious) ==== I never read the FAQ or saw the pictures on Klotz's site prior to purchase.... I simply went to the site and ordered directly, based on a recommendation I read in here. But I have installed the cards and tested them and MINE ARE WORKING GREAT AS WELL. My initial concerns were that ONE - the solder blobs might be able to touch the metal plane of my other Pocket Professional cards and possibly short something and TWO - that I would not be able to get the Klotz's out of the calculator easily once they had been inserted.. BOTH these concerns proved to be false. there is sufficient clearance for the cards in either slot 1 or 2 AND I found a way to extract them from both slot 1 and 2 easily. So all thats left is for me to say THANKS first to Mr. Klotz for producing such a fine product and then to the rest of you in here for responding to evryone's post.... even when it seems a bit silly :) ==== Uh...ooooh... NO it says version #1.18, HP 2000 when I execute the version command. ...... and I don't have a flag -123.... highest flag is -120 BUT the message was my fault anyway... the calculator was trying to switch to approx mode because the expression contained a constant with a decimal part.... and I kept defying it by refusing to allow it to switch.... therefore I was the person cancelling the mode switch... and the calculator was telling me so.... kinda neat huh.... but I found it agravating until I realised what was happening. ==== Alex Did your calc come with ROM ver 1.19-6 ?

This is another thing that I have very little experience with. Seems to me that if you erased a bank used for the operating system flash ROM, then the 49G wouldn't be much good for anything other than a paperweight until you re-flashed it. If you erased a bank used for port 2, then there's a reasonably good chance that you'd lose something that was stored there. If you're up to a practical joke, remember that paybacks are hell; best not to cause a real No System condition. But if you really want to pursue this matter, then I suggest that you start by getting a bit of practice downloading the flash ROM. -- James ==== Maybe it's rude of me to say so, but I'm glad to read that.

BTW where do I find out reported bugs in 1.19.6? to reply directly to me delete the no spam. > You can always flash your calculator back to ROM 1.18 but this will be a > mistake. Feature-wise and bug-wise, 1.19-6 is far better > > I changed the independent variable to 't' (MODE|CAS to get there) Then I put in the equation using eqution writer then SOLVEX (Left Shift 7, (S.SLV) F5) I then got the 2 complex solutions. I don't know if it is really necessary to change the independent variable. Good luck.

Think about the main differences: * most palms use SDRAM or another form of dynamic memory, which tends to consume more power AND require a special controller, which means, more chip space and more power, again, * do you really need a MMU? most MIPS and ARM machinesdo have these so you can run a true multitasking system with paging; I don't see a need for this - what would you page to? ;) * you don't really need that kind of speed if you don't want to run some fool-oriented OS like Windows CE However, a small 16-bit DSP might do, when clocked very low (also good for maths). I think the power consumption could be greatly reduced. Or variable clocking - speed-on-demand, this could also be very good. > Parallel logic is fast but not in a FPGA !

Because boosting clock means higher current; it's easier to use the slow clock. You can use low power slow memories then. > If anybody wants to be realy advanced - why not asynchronous ??

It was alredy done with an 8051 microcontroller at Philips. Eeek. Asynchronous. Go debug that design. ;-) And testing is a real bitch, also. You know, you've got to test the chip. And FPGA will _never_ be as power-efficient as a real silicon so I'd recommend a very low clocked CMOS off-the-shelf. > , Christian Daniel Have fun, Stanislaw Skowronek ==== > > I would either use the MIPS... > The snipped text was not mine, but Christian Daniel's (as seen at the end) X > Because boosting clock means higher current; it's easier to use the slow > clock. You can use low power slow memories then. X Right! I would scale down the process from 2000nm to 250nm AND then the Voltage may be lowered down to 1.8V...1.1V Now you can get the frequency up to 33.3MHz X > And FPGA will _never_ be as power-efficient as a real silicon so I'd > recommend a very low clocked CMOS off-the-shelf. > , Christian Daniel Have fun, > Stanislaw Skowronek I would also like to point out (again) that it may be feasible to change (this is much more work) the serial operations requiring 16*more clocks into one parallel operation (example: add operation) in the Saturn CPU's 64-bit (16*4-bit) nibble-serial registers/ALU's. NOTE: When Pentium 4 was introduced, it was considered very slow CPU. You really have to boost the frequences to get the most out of a design. This is possible with the Saturn, too. It was and still is the best CPU for a *calculator* - operating months in one set of batteries instead of a mere day like the current PDA's ==== Jetzt auch mit HTML-Doku in Deutsch http://users.belgacom.net/EAA/Heiko/HP49/index.htm ..Heiko ==== > Jetzt auch mit HTML-Doku in Deutsch I'm not being pedantic here, I'm just curious about the ammount of German I've forgotten over the past six-ish years.

Sure theres the design problem and the IR issue... but those are nothing serious. 49G is better then GX. Im talking technically here. Theres no question about it. Speed and power are the things that matter in the end (tests). Im not saying that the 48 series is bad (quite good in fact) but the forum should be dedicated to HP CALCS. ....
