Tea Vui Huang writes – “The objective here is to create a low-cost introductory & disposable graphing calculator for the educational use of schools and students who may have difficulty, are unable or may not wish to acquire a stand-alone feature-laden graphing calculator.
The TVH-72g Graphing Calculator is a small 14 Kbytes Mobile Java program that can be installed over-the-air (OTA) or locally via infra-red or data cable from a PC or notebook. For the latter, the student’s phone may be equipped with the software using a school computer hosting a copy of the license-free TVH-72g Graphing Calculator. The TVH-72g occupies barely 0.1% of the J300i’s 12 Mbyte phone memory; it can also be easily deleted by the student when it’s no longer needed. “ – Link.
