How do I open g1r g1s g1m g1a g1e g1n g1l files in FA-124 ?

A:All the .g1* files are designed for use with FA-124, but there are different ways of opening them.

For detailed tutorials see:

Q: FA-124's 9850-9860 conversion doesn't do pictures. How can this be solved ?

A:
1) Use the
Bmp2Cat program to create bmps from the cat file.
(make sure the folder containing the cat file is writable)

2) Make the BMP available for the 9860 either by
using the FX9860G fileconverter

or:

* Use Photo casio to convert the bmps into BASIC code.
* Select Graph 85 from the Options...Calculatrice menu ***
* Select Generer the code from the Fichiers menu.
* Enter a number corresponding to where the program expects the picture to be.
(It's from a 9850 - so it will be one of 1~6)
* Now create a new program area in FA-124 and paste the text from Photo casio
* Transfer the program to the 9860 and run it.
* Repeat the above steps for each bmp from the cat file.


Q: I've lost my manual. Where can I get a new one?

A: Casio provides manuals for the latest models at: world.casio.com
Manuals for older models can be downloaded from www.usersmanualguide.com or Casio New Zealand.


Q: What does the underscore symbol in programs mean ? ( _ )

A: It represents the triangle display symbol on the prgm menu. For details of all the symbols used read the:
Ascii Notation page.


Q: Where can I get a calculator to computer serial cable ?

A: There are two main types of serial cable for casio graphic calculator. (these are different from USB)
Firstly, there is the SB-87 cable available from various online retailers, however this is quite expensive, but you can get the same cable much cheaper by buying FX-Link Kit from
www.dynatech.de.
Secondly, there is the FX-Interface cable, available from www.calculators-online.co.uk

See also the links page for people selling home-made cables.


Q: How do I access .CAT files if I'm using the cable supplied with FX-Interface?

A: The Casform converter can be used to convert cat files into fxi files for use with FX-Interface.
or
you could also makeFA-123 work by applying the FXI&CAT patch. The patch applies only to FA-123 Ver 1.00


Q: I'm typing in a program. How do I get all the functions and symbols ?

A: There are keyguides available for:

Programs containing commands such as Defm, Mcl and Range are for older models and need to be rewritten. See the compatibility page.
Q: Why isn't the F-D fraction to decimal button working ?

A: This button is also used for sending a screenshot to a computer. To get it back to working with fractions, go into the Link mode (C) from the main menu.Then press f6 followed by f1. Now go back to Run mode and the button should work.


Q: Where can I get games for the fx-7400G ?

A:
There are games for the Graph 20/25 (french version of the 7400G) at:
http://adcteam.free.fr/flagsio/jeux.htm.
Also here are a couple of games which don't contain Locate, Text, Getkey or matrices: Super Master Mind. and Gops


Q: Can I use Send( and Receive( to communicate between calculators ?

A: The only way to do this is to create your own intermediate device.
See the
TR-Chat page.


Q: I get a Syn Error when I run a program I've typed in. What's wrong ?

A: There are many ways in which a Syn Error could occur. e.g.


Q: The variables in my program keep changing to incorrect values. What's going on ?

A: Don't use X and Y in programs that also use any graphics or calculus functions as they overwrite these variables. On older models there are other variables that are overwritten as well. See the Side Effects page.


Q: Can Assembler be used on Casio Calculators ?

A: For 9860 assembler see the 9860 Hardware wiki

For assembler on the Algebra FX2.0 and FX1.0. see the AFX section of the links page.

Assembler on 9x50 models has been done by Martin Poupe by opening the case up and using a chip-writer to alter the Rom.
See Martin Poupe's website.


Q: How to use the => symbol on the FX 1.0 and Algebra FX 2.0?

A: There is no button on these models for this symbol, so you could replace A=1=>Goto2 by If A=1:Then Goto 2:IfEnd for example or upload a file to the calc containing the symbol.


Q: What are the Getkey values ?

A: Below is a table of Getkey values for the 9850, 9860 and all similar models.

79 69 59 49 39 29

78 68 58 48  28
