HP-49 ==== I would like to use the last Connex4X with my 48 and understand I have to install an X server library. Can someone point me to one that should be used. you need the Xserver x-modem server library from williams graves availabe at www.hpcalc.org section link pc-hp also if you want to do backups-restorings you wuill need arch48.hp file (i think it is available at the same place) a get the lastest conn4x build 1783 at www.hp.com this xmodem program is really faster and keep your batteries up! ==== > I was playing with my HP DeskJet 990Cxi (IRDA capable, PCL Level 3 > enhanced), trying to make it print from the hp 49G+.

Interesting. I take it that that printer doesn't work with the Red-Eye format, that is, printing to it from the 48 series calculators doesn't work? Does it respond if you try the normal printing commands such as PR1, PRVAR, PRST, PRSTC, and CR? > So, I would like to know how many hp 49G+ users have access to > IR-capable printers. Well, I have the 82240A and 82240B, which are IR capable of course, but not IrDA capable. If I set up my 49g+ to transfer via IR (flag -33 set) and then try an XMIT, it turns on the hourglass annunciator and stops responding to the keyboard. The ON&C warmstart doesn't work; I have to force a warmstart with a paperclip reset. ==== The 48 does not work at all. I believe the minimun acceptable baud is 9600 by IrDA standard, the 48 goes to 2400 I believe. Normal Printing commands do not woks so far. I think they are assuming the 82240A/B as receiver, or maybe dropping the baud rate. However, If I open the IO port to establish connection (led on printer on) and execute PR1, the connection breaks while the command is being executed on the calc \ (hourglass on). My printer manual states that it supports IrLPT, OBEX and JetSend. Maybe the JetSend part is the one doing the trick. I asked for more users of full-size IR-ready printers hoping to sense the interest in this task, and to maybe colaborate in a programming project. I am currently exploring the posibilities with PCL escape sequences. ==== > Any way to get an hp49g+ bug list up?

This list is just for the 49G. I have not seen any list so far for the 49G+ (with either ROM 1.2 or 1.22) Take another look. \HP49G\ seems to refer to a \family\ of calculators. After you choose whether you want to query existing bug reports or enter a new bug report, choose the \Platform\. ==== > To my mind, that is the biggest mistake in the 49g+. > I am also upset about lask of Kermit usability. > There is no serious problem with the KERMIT implementation on the > 49G+.

I could be mistaken, but I think that the problem with transferring such large files has existed right from the start with the 48SX. Perhaps only when using the ASCII transfer mode. ==== After reading on this newsgroup about the Aurora 1000 RPN Financial Calculator, I finally managed to get one (actually, two.) At Fry's they were $15.00. I don't know who makes the calculator, but it's worth the $15.00. It's about 5.5\ by 3\ by 3/8\ with the case closed (the numbers don't come out even in metric either.) Very light weight; feels cheap; key action like a $15.00 unit. The case opens to a keyboard and 1-line display with 10 digits (or 8 digits and 2 exponent.) The RPN is 4-level stack with the fourth level duplicated on drop. Keys are the usual: shift, ENTER, add, subtract, multiply divide, change sign, Clear X, roll, STO; shifted gives: last X, RCL, X-Y interchange. There 20 memorys which are shared with the statistics and programming registers. The functions include (I haven't tried everything yet): Y**X, Exp(X), Log(X), Sqrt(X), 1/X, %, %T, Delta%, round; the financial functions include i, PMT, PV, FV, n, internal-rate-return, net-present-value; statistics include two value statistics x-bar, y-bar, x-sdev, y-sdev, correlation, y-on-x regression and x-on-y regression. There is minimal programming. No real editing. All functions and some tests and a skip available. There is some alphabetic capability. Other than lacking the trig functions, it's quite capable. I would like to have a similar calculator with the trig functions (sine, cosine, tangent, with arcs respectively) and a few functions like area under the normal. I guess I could program the trig functions easily. >Other than lacking the trig functions, it's quite capable. It's a VERY GOOD HP-12C clone. ==== Is there a font size 9 on the new hp49g+ ? (in mode -> disp ) If not, can someone create one ? Unfortunately this is impossible using the current OS font-system. ==== I opened mine up again and took a couple more pictures, and a closer look as well: http://home.earthlink.net/~pjbrogger/images/HP49GPlus_BC3.JPG http://home.earthlink.net/~pjbrogger/images/HP49GPlus_BC4.JPG (These two images are somewhat larger than the previous three -- the last of them is ~600K.) I played with the positive contact spring, and it appears that the outer end of the spiral bends back into the case and is soldered directly to the positive lead on the large capacitor. The inner end of the spiral seems to be free. (Of course, this all applies to my unit but be careful with yours -- there can be no guarantees!) ==== > Grab the non functioning button in a pinching manner, griping both > sides of the button.

Should I do like this: Push down the (not functioning key) rather hard and push the button from side to side to get the \film\ destroyed? My english isn't the best, so I would like to be sure! I haven't bought the calculator yet, and I'm still quite unsure if I should buy it. But it depends on the people who gets this trick \ functioning? So please maybe make this a poll, and tell me if the trick works for you \ to? ==== I did it like you suggest below and it worked. Looks like a quick fix. My \X\ key now works like a charm. ==== > Nice program OHead, but I think you're missing a SetDA12Temp so it > works with the clock on. Sorry, I forgot the ClrDA1IsStat (a SetDA1Temp was there). The program is now still smaller. , you somehow didn't get the point. Quote marks in stack display of strings is not a must. Screen shots of the expanded stack display in my docu are merely examples. http://page.mi.fu-berlin.de/~raut/WR49/index.htm#Misc ==== > is now still smaller. , you somehow didn't get the point.

Sorry, but I just had a quick look at the screen shots, didn't even read \ the text and it surprised me that the strings in the headers are different (didn't even check why)... I trust you know what you are doing and am \ always happy to see that the day I need to use the header I will be able to do so. ==== I haven't tested it on my calc and am not really interested, however, on your screen shots, I see that quote marks are missing from the strings that appear where the header should be. ==== Should they be missing? IMO: Yes! Use \\\\quoted\\\\ to get the quotas, but if you need text without them - you're also without luck... > In a heartbeat!

Calculator woke up positioned two directories removed from Home, with the contents of the variables called to the stack. 2. Calculator frequently powers up with a \1.\ in the stack. Once it had three ones, each in level 1,2, and 3. 3. The multiple equation title bar flashes, but does not appear, unless left shift PREV is depressed, then it appears until you change screens ticks.That's six days and roughly an hour and a half. I have ported a lot of ten years worth of programming from my 48GX, but to my knowledge they are all user RPL...no SYSRPL. All the programs have tested fine with the exception of the MES title bar. I guess I have faith that HP will fix the bugs, but the toy clicker noises the lower keys are making does concern me. ==== > Joe, the SysRPL command ?DispStatus and DispStatus update the header > area immmediately, normally to the default. They don't affect the stack. > The first contains the second one. Would be nice if JYA comments on the > precise difference :-) DispStatus will display the header no matter what. ?DispStatus only calls DispStatus if it's been marked as invalid, corrupted or to be refreshed. It's there to speed up the screen display. If you carefully notice on the HP49G, if you type really fast, the screen will be updated only once you've finished typing.. from rewriting that routine ==== The HP49G simply is way to slow to do certain tasks, for example this: 'EXP(X)-X-3' << DUP 'X' d 4. TAYLR 'X' SOLVE SWAP 'X' 4. TAYLR 'X' SOLVE >> spends 19 seconds on the HP49G, but only 8.5 seconds on the TI89. '9*X-EXP(X-1000)+8973' 'X' 1. TAYLR takes forever on the HP49G (must be a bug), while it's calculated instantly on the TI89. In fact, the TI89 can calculate a Taylor series to degree 25 in one second, of the above expression. There a more than a few Taylor series expansions that take forever on the '49. The TI89 do have its limitations too - it can't develop a Taylor series for 'SIN(X)/X+1' for example. ====== bit.listserv.calc-ti
