Linux Applications for Pocket Calculators



cafix lets you use your Casio calculator interface under Linux to send and receive files, and to control your computer remotely using your calculator. Libcafix, a lib to handle I/O to a Casio calculator, and gcafix, cafix in Gtk+, are also available in CVS.


xfer9860 connects to a Casio fx-9860G graphing calculator and transfers files.

XI Interface

XI Interface is intented to communicate with a Casio (tm) calculator under Linux. It allows you to transfer what ever you want in both directions. That is to say, you can transfer programs, pictures, matrix, screenshots, variables, .... You can use it with all Casio CFX-xxxxGT series, GRAPHxx series, and maybe GRAPH100 and Algebra Fx2 (untested). The program generates and uses .cat file format.

Hewlett-Packard - HP


HPTalx transfers files from/to your HP calculator (HP48/49/50g). It can also update the ROM of a HP49 and has a lot of nice features.


HpTrans is a tool to allow easy transfer and editing of HP49 calculator files. Currently, there are stable xmodem routines and conversion routines between HP49 string files and ASCII text files.


magicSquare is inspired by a game played on a HP48 / 49G.


HP-GCC is a suite of programs that allow you to program ARM-based HP calculators in C.


Nonpareil is a microcode-level simulator for HP calculators introduced between 1972 and 1982, including the HP-35, HP-45, HP-55, HP-25, HP-34C, HP-38C, HP-41CV, HP-11C, HP-12C, HP-15C, HP-16C, and other models. The necessary microcode is included, as is a microcode assembler. The GTK+ toolkit is used for the user interface.

Texas Instruments - TI


TISync transforms your Texas Instruments Calculator into a usable PDA. It allows you to synchronize TI's Organizer application with your PC (Evolution, iCal, or Outlook).


TiLP (formerly GtkTiLink) is a program to transfer data between a Texas Instruments scientific calculator and a computer. It works with all cables (parallel, serial, Black and Gray TI Graph Link, fastAVRlink). It supports the TI82, TI83, TI83+, TI85, TI86, TI89, TI92, and TI92+ calculators. It can send/receive data and backups, make a capture of the calculator screen, and do remote control, using TIGL files. Other features include ROM dumping and IDlist.


G-Star is a clone of the TI-8x calculator game D-Star. It features multiple tilesets and 25 levels from the TI-8x versions of the game.


This library from TIcalc provides functions to use Texas Instruments link cables for TI calculators. It currently supports all cables on i386, including the USB one. Supported cables may vary depending on your architecture.


The libticalcs from TIcalc provides a set of functions to communicate with Texas Instruments calculators. It implements the TI protocol for each type of calculator, independently of the link cable used to establish the link. All graphing calculators from Texas Instruments are supported.

TI85 Emulator

The TI85 calculator hardware emulator works with FLTK and GTK toolkits on Linux workstations and PDAs, as a native MacOS-X Cocoa application, and as QT-Embedded application on iPAQ or Zaurus. In order to use it, you need a ROM image of real Texas Instruments TI85.

Connect Your TI-83 to the Internet

Telnet 83 will allow you to connect to the Internet from your TI-83 and allow you to do IRC, e-mail, or browse the World Wide Web. You need a TI-Graph Link cable, an external 9600 modem, and a cellular phone or wall jack. Telnet 83 goes a step futher than FTerm, RTerm, and ZTerm by featuring an 80x25 scrolling "virtual" screen. This allows you to run programs for Linux such as Pine.

Linux Based Calculators

Scientific Digital Assistant (SDA)

The objective of Scientific Digital Assistant (SDA) project is to create a low cost linux handheld that could be useful for high school and university students, and even professors and scientific and technical professionals. There were similar projects in the past, like HP Xpander , but none have seen the light. There isn't any good and powerful scientific app for handhelds, and laptops can't be get easily for most high school or university students in a lot of countries, so we think that a low cost linux handheld would be a good tool for education and daily work for students that can't easily access to computers or new technologies. The project has two main parts, hardware and software. The hardware part is being studied, and while this happens we will use HP iPAQ to run the software environment created for the SDA. While we are searching for some hardware base, it could be possible to run the software environment in a HP iPAQ handheld, just like prototype.

Qonos is a Linux based calculator being developed by Hydrix, an embedded hardware and software innovation company.
