### #63836 Review of the Casio fx-5800P

Posted by akuzmicich on 15 July 2021 - 10:53 PM

A couple of people asked me to review the humble Casio fx-5800P. Although it has some limitations its a great option for a day to day calculator if you don't need CAS or graphing. I wonder why Casio chose to only put it on the market in a small set of countries?

ps. Hlib2 if you read this I tried to follow a couple of your suggestions in the video.

### #63162 Vintage 1976 Casio fx-102 Scientific calculator review

Posted by MJim on 26 February 2020 - 04:59 AM

**INTRODUCTION**

I don't have that many truly old scientific calculators, and none using the old VFD display technology, so I was pretty interested to check out this old Casio Scientific fx-102 from 1976. Accordingly this is one of the very first consumer calculators that had built in fraction support, which came as a bit of a surprise since I thought the fraction feature was something that came about well after the introduction of LCD based scientific calculators.

One price quoted for the fx-102 in 1976 is 23, which in todays 2020 money would equate to nearly ~149 pounds. This was pretty cheap for a scientific calculator back then (the programmable fx-201P was 60 in 1976 which is about the cost of a fairly high end smartphone at ~388).

**BUILD QUALITY**

Well considering the age of this machine and the condition that it is in, top marks all around. It doesn't look too far off from being new despite it's age of 40+ years.

It is however very big and bulky, and much larger than my fx-82 which was released only half a decade later. With TN LCD displays already being in production at the time, offering lower power consumption and a smaller size, it isn't surprising that VFD displays eventually disappeared.**Front of the fx-102:**

**Rear of the fx-102:**

**POWER CONSUMPTION**

The devices uses 4xAA batteries, and a power consumption figure of 0.4W is printed on the calculator. However I did do a few tests using a fluke multimeter:__Power on current draw peak__: **~43mA**

__Power off current draw peak:__ **~100mA** (not sure why, switching off seems to draw more current).

__Idle (Radians mode) displaying 0 average:__ **39.98mA** (Min: 37.76mA, Max: 44.72mA)__Idle (Radians mode) displaying 8888 8888 88 average:__ **46.68mA** (Min: 40.26mA, Max: 50.02mA)__Calculation current peak:__ **~50mA** (Hard to measure without a function that works continuously).__Calculation voltage average:__ **5.72V** (Min: 5.64V, Max: 5.95V)__Calculated peak power:__ 5.95V * 0.05A = **0.30W**

Switching between different modes (Rad->Deg->Grad->SD) did not effect the current draw.

So I guess the 0.4W figure is fairly honest. I can't locate a manual for the fx-102, but the fx-101 which has a 0.45W drain states a lifespan of 25 hours for alkaline batteries, but with the measured figures and the battery specs (Varta AA longlife alkaline) 30-40 hours doesn't seem all that unrealistic if the fx-102 can make use of all of the available battery capacity.**DIGITS/PRECISION**

It is a 12 digit VFD, but it never seems to use the left most digit. Normally, this calculator seems to handle up to 10 digits for both entry and accuracy. This also means that for numbers big/small enough to require an exponent you actually only have 8 digits of precision, so a good deal of precision is lost once a number transitions to scientific notation, as the last 2 digits are lost in order to display the exponent.

Below is a list of the precision of different functions that I worked out from trial and error (the last digit will be +/-1 in most cases):**10 digits for independent memory** (including M+ and M- operation)**10 digits for basic arithmetic (+,-,*,/)****10 digits for 1/x
10 digits for fractions
10 digits for DMS -> Decimal conversion**

**10 digits for pi constant (3.141592654)**

**10 digits for statistics functions**

**9 digits for square root****8 digits for base10 log, natural log, natural exponential, base10 exponent** (Hidden 9th digit for rounding)**8 digits for trig functions: sin, cos, tan, arcsin, arccos, arctan** (Hidden 9th digit for rounding)**8 digits for x^y function** (2 steps, finds natural log of x, multiplies by y then finds e^(y*ln(x)) - Hidden 9th digit for rounding).

Having functions calculate with less precision than the displayable 10 digits does cause problems however. For example, with the [x^y] function 2^32 should equal 4,294,967,296; which can also fit on the display of the fx-102 without any issue, but since only 8 digits are used, the last 2 digits are truncated returning 2^32 = 4,294,967,200. One way to work around these problems is to avoid using x^y for any numbers greater than 8 digits, but this is rather inconvenient. You could also break it down into smaller parts 2^24 * 2^8, but this requires not only doing the same equation twice over, but also storing the result in memory for each part and then finally multiplying the result at the end.

**CONSTANT CALCULATION MODE**

You can multiply or divide by a constant by either pressing the multiplication/division key twice in succession.

This isn't quite as developed as later Casio models like the D-series (eg fx-100D, fx-115D, fx-991D), where you can also use add and subtract for constants (both real and complex) in addition to using [x^y] and [x^1/y] as constant functions (you specify y, and once set as constant, you can automatically execute these functions by entering for the x-value followed by [=]). It still can be useful however:

For example if you were looking to find circumference of several circles with radius's of 1, 3 & 7.9 metres:

2×[pi] ×× {enter radius}

6.283 185 308

1[=]

6.283 185 308

3[=]

18.84955592

7[.]9[=]

49.63716393

Likewise, if you wished to find the radius from a given circumference of 6, 1, & pi metres:

2×[pi] ÷÷ {enter circumference}

6.283 185 308

6[=]

0.954 929 658

1[=]

0.159154943

[pi]

0.5

Only the [1/x], [Ab/c] and memory storage keys ( [MC], [MR], [M-], [M+]) can be used while remaining in constant mode. Be aware though that if you want to store the result from a constant calculation, you need to enter the number and then press [M+] or [M-] key instead of pressing [=] then [M+]/[M-]. This saves an extra step, showing you the result in addition to storing it, but carries the disadvantage of not seeing the result first before storing it.**TIPS AND TRICKS****Use the [x^y] button instead of ln button for natural logs**

The x^y function is odd in that it returns the natural log of the value for x you enter first, before you enter the value for y to complete the function. However the natural log returned after entering x's value is of a higher 10 digit precision then the built in ln button! Since you can interrupt this calculation, use [x^y] instead of ln. **Use the multiplication constant function for squares**

Unfortunately the fx-102 is missing the squared function, and so squaring numbers is cumbersome, for example, 5^2: 5[x^y]2[=]. You can also use the constant function for multiplication and division instead: 5^2: 5××[=].

Now it's just as many key-presses to use [x^y], so you might ask why. A good reason is that the [x^y] function has at best 8 digits of precision, while basic arithmetic operations including constant mode have 10 digits of precision (+/- 1 digit), so you get a more precise result for the same number of presses.**Alternatively, use statistics mode for squares**

Switch to S.D mode, and then take advantage of the sum squared function:

5^2: 5[=][M+]

This has the advantage of requiring just 3 button presses, but since you need to switch to statistics mode, it isn't particularly practical.

If however you are doing pythagorus type equations, statistics mode can actually save a bit of work, for example:

*"The main tent pole in a conical tent is 3 metres high, and the radius of tent floor is 5 metres. What is the length of the tent fabric stretching from from the tent pole to the floor?"*

d = sqrt(3^2 + 5^2)**{switch to statistics mode}**

3[=] 5[=] [M+]

34**{switch to any other mode, GRAD being closest}**

[sqrt]

5.83095189**8 steps required**

If we performed this in any other mode:

3[x^y]2[=][M+] 5[x^y]2[=][M+] [MR][sqrt]

5.83095189**12 steps required****FRACTION FEATURE**

I was already aware that Casio's fraction feature has 2 implementations, old and new. The older version as found on my fx-100D (c1992) is only able to display fractions while all calculations are also in fraction form. The newer version as found on my fx-991W (c1998) adds the ability to convert decimals to fractions (as long as the number of digits that make up the fraction including fraction marks don't exceed 10).

The Casio fx-102 is using a version of the older implementation, although it is restricted to only using 3 digits for each component of the fraction. Furthermore, it is also limited to 10 digits total, including fraction marks, eg 123+45/678 (which will simplify to 123+15/226). It does work pretty well however, so you can happily continue to add/subtract/multiply/divide in fraction form as long as doing so doesn't exceed 3 digits for any value and 8 digits total for improper fractions.

Unfortunately, this feature comes with a pretty big downside, and that is that any calculation involving fractions can not be stored in memory. As long as any calculation has at one time made use of the fraction feature, you are unable to store that number, even if the fraction was used several calculations ago. Since there are no brackets (or stack), this can make working with fractions problematic, as at no time can you store part of the result of an equation temporarily; for example for the equation 1/2*sin(30) + 1/4*sin(60), it is actually impossible to solve using fractions since you are unable to store the answer to the first part (1/2*sin(30)) before working on the second part.**QUICK TEARDOWN**

For the age of the calculator I thought the soldering and traces were relatively neat. There are two, single-sided PCB's, one for most of the important electronics the other for the keyboard. Both boards are connected by several flat, copper wires. I've opened this calculator up twice now, and these types of connectors make me rather nervous (I trashed my old SH3 fx-9750G2 by breaking something similar). **Overhead view of the two PCB's:**

Unfortunately while I know some basics, I'm not particular knowledgable on electronic circuits. I don't know how VFD's (Vacuum fluorescent display) work, but a quick google suggests they need 2 different voltages, A lower voltage (3V) for the filament (heater) and a higher voltage (12V to 30V) for the segments themselves. Since this works off 4xAA batteries I'm guessing that there is some sort of DC-DC voltage booster. While looking at the photograph of the motherboard I noticed that there was actually a 3rd PCB just to the left of the Hitachi HD36130 CPU, my guess here would be that this is the DC-DC convertor that provides the higher voltage for the VFD display.

**Main board:**

They keyboard PCB looks fairly neatly soldered as well, although it's not hard to spot the repair that was done at some time in the past. Pressing a button looks to short that button to ground. There are 4 separate metal plates for the buttons, each with tabs that contact one of the 5 flat copper pads seen on the front of the keyboard PCB. The 5th copper pad appears to connect to a metal spring which connect the metal face on the calculator to ground. I've always wondered why older Casio calculators do this, would be interesting to get some insight.

**Keyboard PCB rear:**

**Keyboard PCB front:**

**Keyboard & Front cover inside:**

**Keyboard buttons and springs:**

**CONCLUSION**Realistically this isn't the sort of scientific calculator I can see myself using in the modern age. The next oldest calculator I have is the original Casio fx-82 from 1982 (6 years later), which is far more compact, much more energy efficient (0.4W vs 0.0007W, or nearly 600 times less power!) as well as adding much needed stacks in the form of parenthesis, rectangular to polar and polar to rectangular conversions, more constant operations and other functionality. It doesn't however have the fraction key and it is slower, but considering the rate of progress with calculator technology today, it must of been crazy to witness the changes from the late 1970's to early 1980's.

While the fx-102 may not have much utility in modern times, it does still however provide an interesting insight into the evolution of some of the core Casio features that are standard on later models. It has the same direct entry system and the early independent memory works much the same way even in modern calculators (M+/M-). The core fraction entry and display is pretty much unchanged, though the fraction button will toggle between fraction and decimal display, rather than remaining stuck in decimal display. The exponential button is pretty much unchanged, and the Sexagesmial conversion just added the ability to convert from Decimal back to DMS. Finally the constant function would get a few enhancements and stick around for a little over 20 years, when it was finally mothballed with the introduction of the W-series S-VPAM models in 1998.

### #60381 Casio Fx-9860G Sdk Tutorials (2016 Avaiable)

Posted by Viliami on 09 August 2016 - 06:55 AM

The Fx-9860gii SDK uses C by default (it also supports C++, SH4A and SH3 ASM), the SDK just uses the standard C with some extra functions for I/O and drawing.

In the "fxlib.h" header file, there are a bunch of Bdisp functions, these functions deal with drawing pixels to the screen and clearing them.

e.g Bdisp_PutDisp_DD() is the function used to draw a pixel to the screen and Bdisp_AllClr_DD() is the function used to clear all the pixels from the screen.

There is a good tutorial created by Fez and reformatted by Helder7 about the Bdisp functions and basic I/O over here: http://www.casiopeia...php?f=20&t=1420

You can also download the official Casio docs on the fxlib library over here: http://edu.casio.com...greement.html#2

Here is a hello world program, most of this is auto-generated by the SDK when you create a new project:

/*****************************************************************/ /* */ /* CASIO fx-9860G SDK Library */ /* */ /* File name : [ProjectName].c */ /* */ /* Copyright (c) 2006 CASIO COMPUTER CO., LTD. */ /* */ /*****************************************************************/ #include "fxlib.h" //**************************************************************************** // AddIn_main (Sample program main function) // // param : isAppli : 1 = This application is launched by MAIN MENU. // : 0 = This application is launched by a strip in eACT application. // // OptionNum : Strip number (0~3) // (This parameter is only used when isAppli parameter is 0.) // // retval : 1 = No error / 0 = Error // //**************************************************************************** int AddIn_main(int isAppli, unsigned short OptionNum) { Bdisp_AllClr_DDVRAM(); // clear screen PrintXY(1,1,"Hello World!",0); // print "Hello World!" to the VRAM Bdisp_PutDisp_DD(); // copy pixels from the VRAM to the actual display return 1; } //**************************************************************************** //************** **************** //************** Notice! **************** //************** **************** //************** Please do not change the following source. **************** //************** **************** //**************************************************************************** #pragma section _BR_Size unsigned long BR_Size; #pragma section #pragma section _TOP //**************************************************************************** // InitializeSystem // // param : isAppli : 1 = Application / 0 = eActivity // OptionNum : Option Number (only eActivity) // // retval : 1 = No error / 0 = Error // //**************************************************************************** int InitializeSystem(int isAppli, unsigned short OptionNum) { return INIT_ADDIN_APPLICATION(isAppli, OptionNum); } #pragma section

As you can see from above, there is no main() function, unlike standard C our entry point to the program isn't the main() function, it is the AddIn_Main() function.

### #60058 Try To Hack Your Classwiz Models!

Posted by Hikari Calyx on 12 October 2015 - 10:35 AM

Well, I'm from Baidu fx-ES(MS) bar which is a community to discuss calculators. My ID is jyx8151 there.

I'm going to introduce how to hack your Casio ClassWiz Models.

Right now, It should be available in these models:

fx-570EX, fx-991EX, fx-82CN X, fx-350CN X, fx-95CN X, fx-991CN X, fx-530AZ, fx-JP500, fx-JP700, fx-JP900, fx-570AR X, fx-991AR X, fx-92 Speciale College, fx-92B Speciale College, fx-87DE X, fx-991DE X, fx-570SP X Iberia, fx-991SP X Iberia.

If you don't have these models, you may use an emulator. It's available on Casio World Education Website for 90-day-trial except for fx-82/350/95/991CN X and fx-JP500/700/900.

Unfortunately, you can't hack fx-82/85/350EX, fx-82/95AR X, fx-82/350SP X Iberia, fx-95CN X VerB right now because Casio fixed this leak.

It may also work on fx-570VN PLUS, fx-915ES, fx-995ES.

The basic tutorial to hack is making an empty box on the screen:

1. 1[÷][(][(]1, along with 13 square roots, 1.

2. Move the cursor to the end.

3. Alpha[∫] or Alpha[x^3] in order to input a colon ":", then input another square root.

4. For fx-82/350/95CN X VerA and fx-991CN X VerA/VerB, press [=] twice, then syntax error. Press left, and delete others but leave the empty box alone.

5. For fx-991CN X VerC and other models , press [CALC],[=], and you may get the same result.

6. After you get an empty box, press left to make the cursor is at the left of box, then press right, then you may see the cursor won't move.

7. Then you can input anything in order to hack the calculator. For more details, I'll edit this post later. If you find the empty box won't appear, please make a reply and tell me your models and version in diagnostic mode.

P.S. Only Chinese and Vietnamese Casio Calculators have an anti-counterfeit label. To get the sum and Px info, press MENU when CY-2xx appears.

### #59479 Casio Prizm Mandelbrot Explorer

Posted by ProgrammerNerd on 11 September 2014 - 11:41 PM

The Mandelbrot fractal is quite a sight.

Such wonder and amazement that can be found while viewing the Mandelbrot fractal can now be had on the Casio Prizm graphing calculator.

In addition this program can also be compiled for the PC assuming SDL is installed.

Just run make and it will be up and running.

There is very little difference in function between the PC version and the casio prizm version, the resolution is higher but that is it.

The controls are

Left, right, up, down moves the window in that direction

Menu key or ESC on the PC, exits to the menu or exits the program (PC)

F1 sets maximum iterations to 65535

F2 sets the maximum iterations to 224 (this is the default upon starting the program)

F3 toggles deep mode which is on by default. This means you can zoom in deeper with a slight performance hit.

I do not notice the difference

1 subtracts one from the maximum iterations

2 adds one to the maximum iterations

3 subtracts ten from the maximum iterations

4 adds ten to the maximum iterations

5 subtracts 100 from the maximum iterations

6 adds 100 to the maximum iterations

Shift zooms in

Alpha (ALT on PC) zooms out

Source code https://github.com/C...-Prizm-Explorer

Binary https://github.com/C.../mandelbrot.g3a

Screen shots (from the PC version which gets very similar output differing only in resolution).

Anyways if you have any bug report(s), feature request(s), pull request(s), patch(es) or whatever relates to this I would be happy to hear about them.

Hello everyone, I am posting a game with the source code that I have downloaded. It is not my program. I am however making changes and updates to the program as it is needed. Let me know if you want a copy of the modified game source code. I also am having it as a txt file!

I am in the stages of remaking the game right now. It can be used on fx-9750 family and 9860g family and CG-50 and maybe others.

http://cabbresson.tr...sio/Kingdom.cat

Here is the original program. As you can see it is very unsightly and not organized!

A quick description of game: A great role playing game with many features. Includes a bank, many weapons, armor, lands and enemies. Gain higher ranks to open up new lands. Addictive and fun!

I have finally finished the program! I added some new code as well!

Notes:

-Added new areas

-Added new code to make the bank work

-Added new weapons

-Added new enemies

-Added new ranks

-Added new armor

-Added a harder experience

-Added new code so the healers would work

-Lowered Prices

I have played this game a lot and it is very fun and addictive!

In total the game takes about 13000 bytes of memory!

### #59472 Nested If Statement Syntax Error

Posted by TeamFX on 11 September 2014 - 05:07 PM

Every 'If' needs an 'IfEnd' and there are quite a few missing in your program.

You can also use the conditional jump command "=>" (Shift + VARS / F3 / F3) as an 'If-Then' replacement.

Instead of writing...

If A=2

Then A+1->A

IfEnd

You write...

A=2=>A+1->A

The conditional jump command does not allow more than one statement to be executed.

### #31796 Casio Basic Tutorial

Posted by huhn_m on 28 November 2005 - 05:03 PM

Those of you who know other programming languages have probably seen a big problem in what you have read so far, what if you need more than 28 variables in your game? A long time ago (in a calc far, far away), when I was first learning to program I was making little games like Example 1 of this tutorial. But then I started trying to make some more complex games and I ran into a problem, I needed more variables and there were none to be found! Eventually I found the answer: Lists and Matrices.

Lists – A list is exactly that, a list of variables, they can be up to 255 cells long.

Here is a visual of a list with 5 cells:

[ ]

[ ]

[ ]

[ ]

[ ]

to access a cell in a list you just use List #[#] (List 11), the first # represents the number of the list and the second represents the index of the cell. You can use Lists just like you use normal variables, anything you can do with a letter variable you can do to a list, you just have to specify what list and what cell.

Some special list functions:

X->Dim List # : creates a list with X cells in it, all cells are set to 0.

Fill(X,List #) : fills a list with X.

There are others, but you probably wont use them.

Matrices – A matrix is a two dimensional list

Here is a visual of a 5x4 matrix.

[ ][ ][ ][ ]

[ ][ ][ ][ ]

[ ][ ][ ][ ]

[ ][ ][ ][ ]

[ ][ ][ ][ ]

Matrices are just like lists except that they are two dimensional, I like to use them for maps, especially tiled maps. To use a matrix use Mat (letter A~Z)[Y,X] (Mat A[1,1]), the X and Y are reversed, make sure not to confuse them.

Special Matrix functions:

{Y,X}->Dim Mat (letter) : creates a YxX matrix

Fill(#,Mat (letter)) : fills a matrix with a #

Again, there are more, but you wont need them right now.

Tip: List and Matrices are very useful for loops, since they are indexed you can loop through them or use List 1[A] so you can change what list cell you are using dynamically. Also note that you cannot do this with the number of the list.

### #31783 Casio Basic Tutorial

Posted by huhn_m on 28 November 2005 - 04:37 PM

**INTRODUCTION**This tutorial was made to provide an in-depth overview of the Casio BASIC programming language. Many Casio sites offer a basic tutorial for game programming (using Getkey & Locate) where as this tutorial is meant to cover not only those but every other aspect of Casio game programming. This tutorial does not cover the mathematical uses of calculator programming except when it relates to a game. When you have completed this tutorial you will be able to create basic games of your own, and with practice much more advanced ones.

Note by me:

Please be aware that the // signs and the text beyond are comments. However, they are not supported by the calculator, so do not type them in! If you want to add comments to your programs then use the ' chars as prefix.
