• HP50g: HP50g - how to combine the programs and data of some units?

  Like some people on this forum, I have a few pieces of HP50g. On each article there are data and different programs. I'm tired of this mess and want to combine all the programs of all the units in a BASE directory and install the same programs on each unit. As I'll probably do this opreation from time to time in the future, I'm looking for an effective and convenient way to do it. Using the IR ports and programs sending one unit to another would be very slow. Backup on card standard SD also would not be useful in my view (make a backup of each unit, copy on the PC, but what then?).

  Someone on this forum would have hot suggestions to make?

  Hello

  Although you cannot select HOME directory as such, but you can select and copy some or all the elements in the HOME directory and copy only once on the SD card.

  In the FOLDERS menu go to the HOME directory and select the first item and press ENTER, the element highlight will receive a number 1 next to it. In addition to the selection of items with the button ENTER will be number 2, 3 etc. According to him.

  When you have selected all the items you want, COPY and select destination (SD). Unfortunately the built-in FILES does not select the subdirectories of the SD card, but I think that can SDFILER: SDFILER 1.3

• I can not find how to run this program on my HP50g Bessel functions...

  Hello!

  Recently, I buy my HP50g calculator and tried to find and install programs that I need... Solvesys is running, but I can't find how to operate this Bessel function program. I installed it exactly as solvesys (load the lib archive on the calculator and chargue on flash), but I can't find how to run commands, or when they are to crush with. I tried to access the list of orders directly through flash (press the arrow to the right while on archive of lib, then select from the list an eval push) but I get only a result bad argument...

  Can someone guive me a helping hand?

  The link for the program is

  Thanks in advance for your help

  Hi!, Ahkran:

  Happy new year and welcome to the Forum!

  (1) you need to download the library library 764, BESSEL V1.2, HP50G, in the HOME directory.

  Now, you need to install and stay permanently in memory, in any port (0, 1 or 2). Best if the option port 2 (Flash)...

  

  Now, reset the HP50G, with YOU and key F3 (C)...

  Find the library in Port 2, with orange right shift key and key LIB (2), with name BESSE. If necessary, use the NXT (L) key...

  

  Now press the function key (F1... F6), just below the word BESSE, in your HP50G.

  You have to see...

  

  and with NXT - key...

  Carefully read the instructions for use library 764, the .pdf file, the author.

• HP50G cannot compute certain integrals

  Hi, I have a problem of calculating certain integrals on my calculator.

  Here's an example (the answer should be 1/lambda):

  Type 'version' returns the string: "HP50-C revision 2.08 Copyright HP 2006".

  And "WORM" returns 4.20060106

  Is this fixed in a new release or is it simply not able to do this?

  

  Hi!, Kevin Duke:

  The ultimate version of the ROM is C - 2.15... you can download it from... http://www.HPCalc.org/details.php?id=7097

  Now for your problem, look at this... only if lambda, is the number > 0, a, and real result.

  

  The HP50G, you must put it in CASDIR... REALASSUME (REALA)... 'Λ > 0'.

  Now you must configure FLAGS

  

  Now press on, EVAL key... next step OK (F6) and wait ~ 10 "

  

• Manager HP50g-files and subdirectories on SD card

  I tried to create a directory on SD with FM (File Manager). In the menu soft, there is a 'new' function key, but it does not work (as well as to 'renew', 'command'). Although I could copy a subdirectory of the 'House' at the root of the SD with FM, but copy the files to the directory on SD with FM does not work, can copy and access the files on the SD be only to the root?

  Thank you yoann to dig this thread.
  
  The problem was better explained in my last post. I tried to write a program that would create on SD card a directory and a variable in there and save a DATA in the variable:
  
  For other words say once again:
  
  The battery:
  2. THE DATA
  1 way (for example: DIRECT11/VAR22)
  
  The code example:
  < > > - N < <: 3: N + > > OBJ-> STO > >
  
  The problem is that the example code above works fine but only when the path does not contain a directory (IE path = VAR22)
  
  When the path contains a directory name (for example, DIRECT11/VAR22), a 'OBJ-> error, invalid syntax' message.
  
  If the problem is with "/" sign on behalf of path.
  
  Maybe something I don't know or sysPRL a code would, but I do not know sysRPL wrote.
  
  Unfortunately no one not of HP experts on this forum seem to be interested, or is perhaps too difficult, even for them.
  
  Anyway, one of the weak points in the design of HP50g is bad SD card functionality.

  Andy:

  Assuming that you enter the access/objname string path, try this for storage on the SD card:

  ------< < '3'-------> TAG STO-> >

  If the directory did not already exist, it will be created.  Note that this will only work if an object with this name does not exist at this location.  If this object already exists, you will have to serve before the Save.  A more comprehensive solution would be to try to purge the variable first, catch the error where the object was not already there.  The code would then become

  ------< < '3'---> TAG DUP IFERR PURGE CAN END STO-> >

  I hope that will accomplish what you're looking for.

  As has been said, SDFiler is a nice solution for SD card features that is not integrated to 50 g.

• HP50G equations w / complex real Vars &amp; solve for reports of Vars

  Hi guys. I have 2 questions.
  
  1. given an equation with a variable complex and variable real in it, I want to solve for both variables. Here is an example
  
  Given:
  ∠120 has° + jb =-4 + j3
  
  Solve for A and b.
  
  Answer:
  
  A = 8
  b = -3.93

  I know it's possible to solve by hand because A is true and b is complex. But I don't know how to do this on the HP50G because the equation has two variables inside.

  2 it will probably be a bit more complicated. Saw 2 symbolic equations, I want to solve for the report of two variables with respect to the other variables. Here is an example.
  
  Given:
  
  (X Z) / Q + (X - Y) / (X - Y) + R / Q = 0
  / Q (X - Y) = Y/R
  
  Solve for Y/Z depending on X, Q and R
  
  Answer:
  Y/Z = [/(Q+R) R] ^ 2

  I'd be very impressed if anyone can understand these out or already knows how do the following.
  
  Thanks in advance!

  Hello

  (1) :

  It's my approach:

  Settings of the calculator:

  -angle mode: radians (required for the Solver)

  -coord system: rectangular (my choice as it fits x + y * i).

  -Digital and about unchecked

  -operating mode: RPN

  -Flag-27 value complex display that x + y * I

  First angle must be converted to radians, 120 deg = 2/3 * PI radians (PI can be entered as WhiteShift SPC).

  Enter ' (A, ∠2/3 * PI) + B * i =-4 + 3 * I '

  I use 2/3 integers to facilitate the exact mode of address, shortened to ∠ is ALHPA, redshift, 6.

  That the calculator is in rectangular mode, it will be transformed into rectangular.

  You should now have:

  A * COS(2/3*PI) + A * SIN (2/3 * PI) * + B * i =-4 + 3 * I

  Now, press ENTER to duplicate the equation.

  Go to WhiteShift MTH, CMPLX.

  Select RE for the real part:

  A * COS (2/3 * PI) =-4

  Press SWAP (silver arrow)

  Select IM to the imaginary part:

  A * SIN(2/3*PI) + B = 3

  You should now have 2 equations on the stack (the real part of level 2) and the imaginary part in level 1

  You can now put them in a table (2,-> TABLE) and use the Solver to solve for A and b.

  NOTE: when you use real numbers instead of integers, you may use the digital Solver of multiple equations MSLV (NUM. SLV). This requires a set of initial parameters i.e. guess (see Chapter 7 of the great user's Guide or MSLV AUR).

  (2) :

  You cannot resolve Y/Z directly. However, you can solve for and there, Z , then simply ÷ to get Y/Z.

  Level 2: [(X-Z) / Q + (X - Y) / (X - Y) + R / Q = 0 (X - Y) / Q = Y/R]

  Level 1: [Y - Z]

  S.SLV, point 6 or F6 to SOLVE

  Will result in a list or a table that contains solutions for Y and Z depending on X, Q and r. use OBJ-> once or twice to put both equations separately on the stack, then press fracture for Y/Z.

  Note, you can change the representation of the solution by the factor or simplify (best way to find who is to press down arrow money to enter the Equation Editor, select the right side of the eqation then de FACTO or SIMP).

  I hope this helps.

• Solve this linear system HP50g

  Hi guys,.
  I am an engineer in electrical engineering and have to solve systems of linear equations on a regular basis, so that the functionality is very important for me. Everything works very well, 95% of the time but sometimes I meet systems that the HP50g doesn't seem to like. For example one below.
  
  I want to solve for x, y, z and one in terms of V
  
  V- 100000 x +is-100000 100000x= 0
  -250000is-V+ 100000x100000z= 0
  -250000z+ 100000one+ 100000y= 0
  a+ 100000-250000z= 0
  
  After these 4 equations is on the stack, I'm them in a vector by pushing {4} in the stack and then by pressing -> ARRY. Then I push the variables I want to solve for the battery, x, y, z and a and a vector of them. Then, I use LINSOLV to solve the system. However, when I do it this way, the calculator gives me an equation for x, an equation for y and 2 equations for z and no equation for s. I'm not sure what I'm doing wrong. Is there another way to do that would give me 4 equations, one for each variable I want to solve for in terms of V?
  
  If my method to solve linear equations is somehow confusing, I basically followed this video
  http://www.YouTube.com/watch?v=z802L29JyQE
  
  Thanks in advance.

  Hello

  Do not know exactly how you typed, so I'm being explicit just for some b:

  Notes:

  (1) as an equation is entered, use ' '

  (2) it is preferable to use a comma to separate the real and imaginary parts

  (3) explicit use multiply

  If the entry will look like this:

  '(4,3*X) = (4.7)'

  For this simple equation and assuming that X is defined as an independent variable (reproduced by 'X' in the top middle of the screen), you can use SOLVEVX for this one: (No. 5 in S.SLV menu or F5 if you use soft-keys)

  with "_Approx" uncontrolled, the answer is:

  X = 7/3

  with "vabout" checked the answer is:

  X = (2.333333333,0) (although X is part of the imaginary number, it is himself a real number).

  Kind regards.

• Load a small program on a HP50g from memory card (SD card)

  Can anyone help me please with loading a close the program on my HP50g calculator from a SD card?

• HP50g: Strange table HP50g Representation when polar mode

  Hi all

  I noticed that under certain conditions, an array of real numbers is represented very strangely on the HP50g.

  The situation is, I have my polar coordinates to the value and I create an array of real numbers using ARRY->.

  For example, in the RPN, I put 1, 2 and 3 on the stack, type 3 and then use the command ARRY, telling the calculator that I intend to create a table of 3 elements by using the 3 previous values on the stack->.

  I expect to see is a table with items 1, 2 and 3, but this isn't what's happening. Instead, I get the polar form (1.2) for the first two elements, then the number 3 (see image).

  If I change from rectangular coordinates table shows what I expected, but it still seems strange to the polar form what is happening. Conversely, if I create the matrix using other methods, for example, the MTRW application, it does not happen even under the same conditions.

  Any ideas on the issue?

  Thank you all in advance

  Spoiler (Highlight to read)

  

  Just a wild guess: does still happen after running the CASCFG command, which resets the CASE settings to their default values?  I tried many settings of the indicator and have not been able to reproduce the behavior you describe, but I still think it's a flag setting causing your trouble.  Unless you have an installed library that changes the display, whereby the Paris are open.

• HP50g summons to infinity problems

  I am doing a summons to infinity and if I keep it in the equation writer I just get the hourglass and he can't understand it. If I eval in the stack with indicator 3 checked I get the same thing, but if I hit Cancel all of a sudden the right answer appears. If I uncheck flag 3 then all that I get is (?). Can someone tell me please how to properly evaluate a summons to infinity. Thank you.

• Problem program instalation Hp50G.

  Hi, I imported from Hpcalc.org, the heavenly Sapacom pack. I have the library on port 3 (SD) in my HP50g. The library has 130933 bytes and as the readme says "HP49/50 library can be installed on port 0, or IRAM, due to.
  size in the banks of flash limitations.

  I tried to copy the SD and paste on port 0, but then a legend appears saying "error: not enough memory.

  I read on port 0 and I see 81 KB.

  I'd like know if someone could help me on this problem.

  Thanks in advance

  Harrigorri

  Hello

  For this program, you must have at least 128kB (131072 bytes) free. Only Port 0 supports this in a contiguous block.

  Port 0 is the same part of RAM than the VAR country. If you have many programs user, data & libraries stored there, you need to save some of them until you have enough free memory in Port 0. (You will probably need free more space to run programs in fact).

  If you have libraries in Port 0, try putting in Port 2 work as many Port 2 as well. (You may have to do a warm restart with-F3 after moving to them).

  I hope this helps.

• HP50g: HP50g - hot to check if the object of the stack is a number?

  How to check if an object on the stack is a number or another type of data? There seems to be no any function to check on 50g.

  50 g advanced users to see, page 1-13:

  "The order TYPE ([left SHIFT] PRG-> TEST-> NXT-> TYPE) accepts any object as argument and returns the number that identifies the type of this object." For example, 'HELLO' TYPE returns 2, the value of a string object. See table of object types in Chapter 3, in the command TYPE, to find objects of calculator and corresponding type numbers.

  Generally want to DUP the object to the level of the stack 1 first of all, because likely you want to do something with it, after checking his type.  The following RPL program checks the type of the object in level 1 of the pile and adds a string to the stack indicating its type.  Only some of the possible types are checked and a generic "something else" translates to others:

  «
  
    TYPE OF DUP
  
    CASE
  
      DUP 0 == THEN DROP 'real number' END
  
      DUP 1 == THEN DROP "complex number" END
  
      DUP 2 == THEN DROP 'chain' END
  
      DUP 3 == THEN DROP "real array" END
  
      DUP 5 is THEN DROP 'list' END
  
      DROP "something else"
  
    END

Now I press the Board down and the equation is moving to the center of the screen and it is marked. But now, it is impossible to move the later equation on the top line of the screen and impossible to work with her. I can do what I'm going, all the isn´t of use.

  Thanks for your help.

  No, it will not work.

  When equations is on the bottom line of the screen, save it on behalf of the EQ (in the home directory).

  However, I recommend a use you the second method suggested in my post:

  NUM. SLV, SOLVE EQUATIONS, OK

  Highlight the line EQ

  Select "CHOOS" by pressing F2

  Now select 'TREE' by pressing F1

  and navigate to the desired location of your equation, for example 3: SD and press 'OK' F6

  then highlight the name of your equation, and when it is highlighted, press 'OK' F6

  the equation should now be in the Solver.

  Kind regards.

• USB drivers for HP50g on Windows 8 (64-bit)

  Hi all

  Has anyone tried installing the USB drivers for the 50g on Windows 8?

  Conn4x installed well but USB drivers comes. I tried all available troubleshooting options using the features of Windows 8 compatibility (XP, Vista and 7) and none of them worked.

  So I was wondering, maybe someone here may have already installed and could share some tips.

  Thank you

  Márcio

  I read messages in other forums indicating that the conn4x and the USB driver peut be installed.

  The post on the forum indicated that Windows 8 comes pre-configured with the possibility for signed drivers enabledapplication.

  In order to install the USB driver, signed driver enforcement must be disabled.

  See this forum comp.sys.hp48 post it here:
