Programs written by the user can also use programs in the module as subroutines. The module's programs run directly from ROM, so they leave the calculator's memory free for the user. However, exploiting the computer-like capabilities of the TI-59 is a different matter.
TI-BASIC programs are stored in a tokenized format, they cannot be edited using standard computer text editors, so as the calculator programming community matured, a need for an automated converter arose. The format for computer-stored TI-BASIC programs generated by Texas Instruments' TI-GraphLink application was eventually decoded, and third ...
Later versions of the 99/4A, identified by (C)1983 TEXAS INSTRUMENTS V2.2 on the title page, prevent the use of unlicensed ROM cartridges from third-party manufacturers such as Atarisoft. Both TI-99/4 models use the 16-bit TMS9900 CPU running at 3 MHz. The TMS9900 is a single-chip implementation of a TI-990 minicomputer. Although a full 16-bit ...
Hewlett-Packard calculators supporting the RPL language and input method provide support for a large number of trigraphs (also called TIO codes) to reliably transcribe non-seven-bit ASCII characters of the calculators' extended character set [17] [18] [19] on foreign platforms, and to ease keyboard input without using the CHARS application.
TI BASIC is an ANSI-compliant interpreter for the BASIC programming language built into the 1979 Texas Instruments TI-99/4 home computer and its improved 1981 version, the TI-99/4A. In contrast to most BASICs found on contemporary microcomputers , TI BASIC does not trace its history to Microsoft BASIC , but was instead developed in-house ...
TI InterActive! was a Texas Instruments computer program which combined the functionality of all of the TI graphing calculators with extra features into a text editor which allowed users to save equations, graphs, tables, spreadsheets, and text onto a document.
The TI-84 Plus C Silver Edition was released in 2013 as the first Z80-based Texas Instruments graphing calculator with a color screen.It had a 320×240-pixel full-color screen, a modified version of the TI-84 Plus's 2.55MP operating system, a removable 1200 mAh rechargeable lithium-ion battery, and keystroke compatibility with existing math and programming tools.

Some of the more notable improvements of the TI-82 over the TI-81 include the following: the addition of a link port to enable programs and other data to be transferred between two calculators or between a calculator and a computer; the addition of two new graphing types – polar and sequence, the addition of a new type of data – the list ...
