Virtual TI, or "VTI," is a feature-rich graphing calculator emulator for Microsoft Windows, written in C++ by Rusty Wagner. It features a graphical debugger, a grayscale display, data transfer between computer and emulated calculator, black-link, parallel link and more.

There are currently two versions available:

  1. Virtual TI v.2.5 (beta)
  2. Virtual TI v.3.0 (alpha)

Version 2.5 supports the TI-82, 83, 83+, 85, 86, 89, 92, and 92+. Unfortunately, it is unable to properly emulate later versions of the TI-83 Plus, TI-89 and V200 series. It is also unable to emulate the TI-83 Plus Silver Edition as well as the more recent calculators like the TI-84 Plus.

Version 3.0 supports the TI-73, 83+, and the 83+ SE so far. However, it cannot retrieve the image of a TI-84+, and any file other than Apps cannot be loaded. It also doesn't allow users to save its state.

Virtual TI requires a calculator ROM image. The program itself can extract ROM images from TI calculators via Serial or Parallel connection.

This software has not been updated for several years, unlike TiEmu.

The TI-89 and the TI-89 Titanium are graphing calculators developed by Texas Instruments (TI). They are differentiated from most other TI graphing calculators by their computer algebra system, which allows symbolic manipulation of algebraic expressions—equations can be solved in terms of variables, whereas the TI-83/84 series can only give a numeric result.

MAME is a free and open-source emulator designed to recreate the hardware of arcade games, video game consoles, old computers and other systems in software on modern personal computers and other platforms. Its intention is to preserve gaming history by preventing vintage video games from being lost or forgotten. It does this by emulating the inner workings of the emulated machines; the ability to actually play the video games is considered "a nice side effect". Joystiq has listed MAME as an application that every Windows and Mac gamer should have.

The TI-92 series are a line of graphing calculators produced by Texas Instruments. They include: the TI-92 (1995), the TI-92 II (1996), the TI-92 Plus and the Voyage 200 (2002). The design of these relatively large calculators includes a QWERTY keyboard. Because of this keyboard, it was given the status of a "computer" rather than "calculator" by American testing facilities and cannot be used on tests such as the SAT or AP Exams while the similar TI-89 can be.

<span class="mw-page-title-main">TI-84 Plus series</span> Series of graphing calculators produced by Texas Instruments

The TI-84 Plus is a graphing calculator made by Texas Instruments which was released in early 2004. There is no original TI-84, only the TI-84 Plus, the TI-84 Plus Silver Edition models, the TI-84 Plus C Silver Edition, the TI-84 Plus CE, and TI-84 Plus CE Python. The TI-84 Plus is an enhanced version of the TI-83 Plus. The key-by-key correspondence is relatively the same, but the TI-84 features improved hardware. The archive (ROM) is about 3 times as large, and the CPU is about 2.5 times as fast. A USB port and built-in clock functionality were also added. The USB port on the TI-84 Plus series is USB On-The-Go compliant, similar to the next generation TI-Nspire calculator, which supports connecting to USB based data collection devices and probes, and supports device to device transfers over USB rather than over the serial link port.

<span class="mw-page-title-main">TI-82</span> Graphics calculator produced by Texas Instruments

The TI-82 is a graphing calculator made by Texas Instruments. The TI-82 was designed in 1993 as a stripped down, more user friendly version of the TI-85, and as a replacement for the TI-81. It was the direct predecessor of the TI-83. It shares with the TI-85 a 6 MHz Zilog Z80 microprocessor. Like the TI-81, the TI-82 features a 96×64 pixel display, and the core feature set of the TI-81 with many new features.

<span class="mw-page-title-main">TI-81</span> Graphing calculator produced by Texas Instruments

The TI-81 was the first graphing calculator made by Texas Instruments. It was designed in 1990 for use in algebra and precalculus courses. Since its release, it has been superseded by a series of newer calculators: the TI-85, TI-82, TI-83, TI-86, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, TI-84 Plus Silver Edition, TI-84 Plus C Silver Edition, TI-Nspire, TI-Nspire CAS, TI-84 Plus CE, and most recently, the TI-84 Plus CE Python. Most of them share the original feature set and 96×64-pixel display that began with this calculator, with the exceptions of the TI-84 Plus C Silver Edition and the TI-84 Plus CE family.

QEMU is a free and open-source emulator. It emulates a computer's processor through dynamic binary translation and provides a set of different hardware and device models for the machine, enabling it to run a variety of guest operating systems. It can interoperate with Kernel-based Virtual Machine (KVM) to run virtual machines at near-native speed. QEMU can also do emulation for user-level processes, allowing applications compiled for one processor architecture to run on another.

Programmable calculators are calculators that can automatically carry out a sequence of operations under control of a stored program. Most are Turing complete, and, as such, are theoretically general-purpose computers. However, their user interfaces and programming environments are specifically tailored to make performing small-scale numerical computations convenient, rather than general-purpose use.

The TI-Nspire is a graphing calculator line made by Texas Instruments, with the first version released on 25 September 2007. The calculators feature a non-QWERTY keyboard and a different key-by-key layout than Texas Instruments's previous flagship calculators such as the TI-89 series.

In computing, a character set is a system of assigning numbers to characters so that text can be represented as a list of numbers. For example, ASCII assigns 61 to "A". As part of the design process, Texas Instruments (TI) decided to modify the base Latin-1 character set for use with its calculator interface. By adding symbols to the character set, it was possible to reduce design complexity as much more complex parsing would have to have been used otherwise.

Cemetech is a programming and hardware development group and developer community founded in 2000. Its primary focus is developing third-party software for TI and Casio graphing calculators, along with a focus on mobile and wearable computing hardware. Among its most notable projects are the Doors CS shell for the TI-83+ series of graphing calculators, the Clove 2 dataglove, the Ultimate Calculator, and the CALCnet / globalCALCnet system for networking graphing calculators and connecting them to the Internet. The Cemetech website also hosts tools for calculator programmers, including the SourceCoder TI-BASIC IDE and the jsTIfied TI-83+/84+ emulator. The founder of the site, Dr. Christopher Mitchell, began the site to showcase his personal projects, but it has since branched out to become one of several major sites in the TI calculator hobbyist community and a source for hardware and programming development assistance. It has incubated many software and hardware projects which began in the calculator community but included microprocessor development, general electrical engineering, desktop applications, and mobile/web applications.
