Casio graphical calculators

Looking for programming info? Try the Casio Graphical Calculator Encyclopaedia. (The part of my pages I put most effort into. Sorry it's been down for a while, but it's new and improved now.)
Looking for programs? Try my programs page.

For quite a while I've been interested in these fascinating little doohickeys. These pages contain anything which I think is useful to know about programming them and a range of some of the best (IMHO) programs for them around.

My calc

My first graphical calculator was an fx-7000. This had 422 bytes of available programming space. My second graphical calculator was an fx-9700GE, which had 24000 bytes of programming space. I noticed a difference. A few weeks ago, I got a cfx-9850G. It has these pros and cons compared to the fx-9700GE:


Over the past few years myself and Tom Wheeley have been gradually hacking away at these calcs and discovering their inner workings. A lot of this work is currently being organised into the CTF (calculator text format), a standard format for writing down calculator programs so that they can be read by humans but can also be sent via cable to the calculator. In a few months, if all goes well, all Casio calculator websites will be adopting this format for their programs.

For general info on Casio calculator hackery, the CTF, and links to other good calc pages, you should try Tom Wheeley's calc page. It also has software (CaS) for transferring files between a calculator and computer via a cable and info about where to get cables.

Casio now provide free software for up/downloading files over a cable.
It can be downloaded from:
Now available: Progs in .cas format for uploading with this or CaS.
