The Casio fx-9860G is a series of graphing calculators manufactured by Casio Computer Co., Ltd. There are both monochrome and four-colour machines in the CFX-9850/CFX-9950/fx-9860 family of calculators.[1] All of them are capable of being programmed by means of sophisticated languages and tools including assembly language, Basic variants, and ports of programming languages such as C, as well as hosting add-ins which are compiled on a computer and then downloaded to the calculator. [2] Some of them also have touch screens which can be manipulated with a stylus.[3]

There are several versions of the fx-9860G; the standard fx-9860G, often referred to as the 'vanilla' flavor, and the SD, AU and Slim versions.

  • The AU version used to limit the amount of internal flash memory available to 800 Kb to meet Australian school regulations, although it has now been upgraded to 1.5MB.
  • The SD variant comes with an SD expansion card slot, allowing read and write access up to 2 GB of memory on a SD memory card.
  • The Slim version has a back-lit display, on-board help, and is designed as a clam-shell to minimize its size.
  • The fx-9860GII and fx-9860GII SD became available in May 2009. These calculators have backlit displays and the Geometry (in user mem) and ECON2 apps preinstalled. They also have new mathematical functions.[4]

The usual fx-9860G and fx-9860G SD are marketed in France as Graph85 and Graph85 SD.

The French versions of the GII models are the Graph 75 and Graph 95. The Australian version of the GII is the fx-9860G AU PLUS.

Programming

The calculators can be programmed in different ways. The fx-9860G's come with a built-in BASIC-like interpreter (Casio BASIC), allowing the user to create simple and complex programs using built-in functionality.

The other method is to create an add-in. Add-ins are binary programs, executing directly on the calculator's CPU. CASIO has released two official add-ins, GEOMETRY and PHYSIUM. An SDK was released by CASIO in 22/01/2007, allowing users to create their own add-ins, though no support is provided for this by CASIO. The add-ins and the SDK are available for registered users at CASIO's website.

Add-ins and the SDK allow more powerful applications to be developed, and have been used to create an interpreter for the popular Multi-Platform Language for Calculators. After was created a lua interpreter (luaFX) and a new language called Malical for users who do not want to code in C or basic.

Recently an OnCalc C Compiler was released.

I/O, Synching, and Programme Development

As shown in Chapter 21 of the Casio 9850GB Plus users' guide, the calculators in this series can utilise Casio label printers of the KL series for output. [5] As with other calculators, a cable (the FA-123 and FA-124)[6] can be used to send information (variables, text, programmes, &c) from one calculator to another or from the calculator to a computer and vice versa[7] and a CD-Rom containing drivers and software for synching and backing up, editing programmes, a screen-capture application and information about the calculator.[8] The data port on the calculator takes a 1/8-inch audio-type plug, as do Texas Instruments and Sharp programmable calculators, and later versions in this series have both this port and a Mini USB port of the same sort found on HP calculators subsequent to the model HP48 and most cellular telephones.[9]
