TI-81
The TI-81 was the first graphing calculator released by Texas Instruments. It was designed in 1990 for use in algebra and precalculus courses. Since its original release, it has been superseded several times by newer calculators: the TI-85, TI-82, TI-83, TI-86, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, TI-84 Plus Silver Edition, and most recently the TI-Nspire and TI-Nspire CAS. Most of these share the original feature set and 96×64-pixel display that began with this calculator. Features The TI-81 is powered by a Zilog Z80 microprocessor, like those used in almost every other Texas Instruments graphing calculator (except the TI-80, TI-89, TI-89 Titanium, TI-92, TI-92 Plus, Voyage 200 and TI-Nspire series). However, the processor is clocked at 2 MHz whereas the other Z80-powered Texas Instruments calculators run at speeds of at least 6 MHz (the TI-83 Plus Silver Edition, TI-84 Plus, and TI-84 Plus Silver Edition can run at 15 MHz). It contains 2400 bytes of user RAM, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TI-82
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 96x64 pixel display, and the core feature set of the TI-81 with many new features. Features The TI-82 is powered by the same processor that powered its cousin, the TI-85, a 6 MHz Zilog Z80 microprocessor. This was an improvement over the TI-81's 2 MHz Z80 processor. In addition, the available RAM was increased more than tenfold – from 2400 bytes to 28734 bytes (slightly more than the TI-85). 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 g ...

TI-80
The TI-80 is a graphing calculator made by Texas Instruments. It was originally designed in 1995 to be used at a middle school level (grades 6-8). The TI-80 featured a 48 x 64 dot-matrix display with a 5 x 3 pixel font, which is the smallest screen of any TI graphing calculator. It also featured the slowest processor (980 kHz proprietary) of any TI graphing calculator. The first revision of the TI-80 'A' contained a proprietary Toshiba T6M53 ASIC while subsequent revisions contained a Toshiba T6M53A. Additionally, the TI-80 had the processor on board the ASIC, unlike later calculators like the TI-83, TI-83 Plus, and TI-84 Plus which had separate ASIC and processor chips in certain models. In comparison, the TI-81, released in 1990, featured a 2 MHz Zilog Z80 processor. However, the TI-80 did feature 7 KB of RAM (compared with the TI-81's 2.4 KB). The TI-80 also had more built-in functions than the TI-81 (such as list and table functions, as well as fraction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TI-85
The TI-85 is a graphing calculator made by Texas Instruments based on the Zilog Z80 microprocessor. Designed in 1992 as TI's second graphing calculator (the first was the TI-81), it was replaced by the TI-86, which has also been discontinued. The TI-85 was significantly more powerful than the TI-81, as it was designed as a calculator primarily for use in engineering and calculus courses. Texas Instruments had included a version of BASIC on the device to allow programming. Each calculator came with a cable to connect calculators (simply a three-conductor cable with 2.5 mm phone connectors on each end). Another cable known as the TI-Graph Link was also sold, along with appropriate software, to connect the calculator to a personal computer. These cables made it possible to save programs and make backups. Assembly programs Enthusiasts analyzed memory backups and discovered that entries in the calculator's CUSTOM menu pointed at specific memory locations. With this kn ...

TI-83 Plus Silver Edition
The TI-83 series is a series of graphing calculators manufactured by Texas Instruments. The original TI-83 is itself an upgraded version of the TI-82. Released in 1996, it was one of the most popular graphing calculators for students. In addition to the functions present on normal scientific calculators, the TI-83 includes many features, including function graphing, polar/parametric/sequence graphing modes, statistics, trigonometric, and algebraic functions, along with many useful applications. Although it does not include as many calculus functions, applications and programs can be written on the calculator or loaded from external sources. The TI-83 was redesigned twice, first in 1999 and again in 2001. TI replaced the TI-83 with the ''TI-83 Plus'' in 1999. The 2001 redesign introduced a design very similar to the TI-73 and TI-83 Plus, eliminating the sloped screen that had been common on TI graphing calculators since the TI-81, and included Flash memory, enabling the device's ...

Zilog Z80
The Z80 is an 8-bit microprocessor introduced by Zilog as the startup company's first product. The Z80 was conceived by Federico Faggin in late 1974 and developed by him and his 11 employees starting in early 1975. The first working samples were delivered in March 1976, and it was officially introduced on the market in July 1976. With the revenue from the Z80, the company built its own chip factories and grew to over a thousand employees over the following two years. The Zilog Z80 is a software-compatible extension and enhancement of the Intel 8080 and, like it, was mainly aimed at embedded systems. Although used in that role, the Z80 also became one of the most widely used CPUs in desktop computers and home computers from the 1970s to the mid-1980s. It was also common in military applications, musical equipment such as synthesizers (like the Roland Jupiter-8), and coin-operated arcade games of the late 1970s and early 1980s, including '' Pac-Man''.

TI-BASIC
TI-BASIC is the official name of a BASIC-like language built into Texas Instruments (TI)'s graphing calculators. TI-BASIC is a language family of three different and incompatible versions, released on different products: * TI-BASIC 83 (on Z80 processor) for TI-83 series, TI-84 Plus series * TI-BASIC 89 (on 68k processor) for TI-89 series, TI-92 series, Voyage 200 * TI-BASIC Nspire (on ARM processor) for TI-Nspire and TI-Nspire CAS TI rarely refers to the language by name, but the name TI-BASIC has been used in some developer documentation. For many applications, it is the most convenient way to program any TI calculator, since the capability to write programs in TI-BASIC is built-in. Assembly language (often referred to as "asm") can also be used, and C compilers exist for translation into assembly: TIGCC for Motorola 68000 (68k) based calculators, and SDCC for Zilog Z80 based calculators. However, both of them are cross-compilers, not allowing on-calculator programming. TI-BA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TI-89
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. TI-89 The TI-89 is a graphing calculator developed by Texas Instruments in 1998. The unit features a 160×100 pixel resolution LCD and a large amount of flash memory, and includes TI's ''Advanced Mathematics Software''. The TI-89 is one of the highest model lines in TI's calculator products, along with the TI-Nspire. In the summer of 2004, the standard TI-89 was replaced by the TI-89 Titanium. The TI-89 runs on a 32-bit microprocessor, the Motorola 68000, which nominally runs at 10 or 12 MHz, depending on the calculator's hardware version. The calculator has 256 kB of RAM, (190 kB of which are available ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Voyage 200
The TI-92 series of graphing calculators are a line of calculators produced by Texas Instruments. They include: the TI-92 (1995), the TI-92 II (1996), the TI-92 Plus (1998, 1999) 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. TI-92 The TI-92 was originally released in 1995, and was the first symbolic calculator made by Texas Instruments. It came with a computer algebra system (CAS) based on Derive, geometry based on Cabri II, and was one of the first calculators to offer 3D graphing. The TI-92 was not allowed on most standardized tests due mostly to its QWERTY keyboard. Its larger size was also rather cumbersome compared to other graphing calculators. In response to these concerns, Texas Instruments introduced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
