At the turn of the millennium, the line between a graphing calculator and a handheld computer was not always clear, as some very advanced calculators such as the TI-89, the Voyage 200 and HP-49G could differentiate and integrate functions, solve differential equations, run word processing and PIM software, and connect by wire or IR to other calculators / computers.

Some graphing calculators, such as the Casio 9860 series, HP-49 series, TI-89, and TI-Nspire, or the TI-83 Plus / TI-84 Plus with the PrettyPt add-on, can perform pretty-printing.

For Further Mathematics an approved graphics calculator ( for example TI-83 / 84, Casio 9860, HP-39G ) or CAS ( for example TI-89, Classpad 300, HP-40G ) can be used.

Experiments with the TI-89, 92, 92 + and Voyage 200 machines show the possibility of installing some variants of other systems such as a chopped-down variant of CP / M, an operating system which has been used for portable devices in the past.

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.

The calculator can also run most programs written for the TI-89 and TI-92 as well as programs specifically written for it.

The TI-89 Titanium is essentially a Voyage 200, except it doesn't have an integrated keyboard.

In many testing situations, the TI-89 and TI-89 Titanium, along with the HP-49 series, are the most powerful and function-rich graphing calculators that are permitted: the TI-92 series, with otherwise comparable features, have QWERTY keyboards that result in them being classified as computer devices rather than calculators.

Other TI graphing calculators have been designed to be appropriate for calculus, namely the TI-85, TI-86, TI-89 series, and TI-92 series ( TI-92, TI-92 Plus, and Voyage 200 ).

The TI-89 is essentially a TI-92 Plus with a limited keyboard and smaller screen.

The TI-92 was then replaced by the TI-92 Plus, which was essentially a TI-89 with the larger QWERTY keyboard design of the TI-92.

The TI-89 Titanium also has a USB On-The-Go port, for connectivity to other TI-89 Titanium calculators, or to a computer ( to store programs or update the operating system ).

There are some minor compatibility issues with C and assembly programs developed for the original TI-89.

This, along with its successors ( including the TI-89 series and the newer TI-Nspire CAS released in 2007 ) featured a reasonably capable and inexpensive hand-held computer algebra system.

Texas Instruments uses the 68000 in its high-end graphing calculators, the TI-89 and TI-92 series and Voyage 200.

The TI-89 and the TI-89 Titanium are graphing calculators developed by Texas Instruments.

The TI-89 is a graphing calculator developed by Texas Instruments ( TI ) in 1998.

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, 12, or 16 MHz, depending on the calculator's hardware version.

The TI-89 is significantly smaller — about the same size as most other graphing calculators.

The TI-89 is not permitted on the ACT or the National Fundamentals of Engineering exam, although it is permitted on the SAT examinations.

The major advantage of the TI-89 over lower-model TI calculators is its built-in computer algebra system, or CAS.

The TI-89 is directly programmable in a language called TI-BASIC, TI's derivative of BASIC for calculators.

There are four hardware versions of the TI-89.

HW1 and HW2 correspond to the original TI-89 ; HW3 and HW4 are only present in the TI-89 Titanium.

The TI-89 Titanium was released in the summer of 2004, and has largely replaced the popular classic TI-89.

The TI-89 Titanium is referred to as HW3 and uses the corresponding AMS 3. x.

The TI-89 Titanium also features some pre-loaded applications, such as " CellSheet ", a spreadsheet program also offered with other TI calculators.

In some cases, only one character needs to be changed ( the ROM base on TI-89 is at 0x200000, whereas the TI-89 Titanium is at 0x800000 ) by hand or by patcher.

At the time Blowfish was released, many other designs were proprietary, encumbered by patents or were commercial / government secrets.

The Massachusetts Turnpike Authority ( MTA ), which had little experience in managing an undertaking of the scope and magnitude of the CA / T Project, hired a joint venture to provide preliminary designs, manage design consultants and construction contractors, track the project's cost and schedule, advise MTA on project decisions, and ( in some instances ) act as the MTA's representative.

Tribal boomerangs may be inscribed and / or painted with designs meaningful to their makers.

" Bombardier acquired the assets and designs of Budd Company, Pullman Company, and American Locomotive Company / Montreal Locomotive Works, the latter of which continued in the locomotive business until 1985.

Three open-source keyer / keyset designs are available: The pickey a ps / 2 device based on the PIC microcontroller, the spiffchorder a USB device based on the Atmel AVR family of microcontrollers, and the GKOS keypad driver for Linux as well as the Gkos library for the Atmel / Arduino open source board.

In the early 1970s, this gave rise to ideas to return to simpler processor designs in order to make it more feasible to cope without ( then relatively large and expensive ) ROM tables and / or PLA structures for sequencing and / or decoding.

Newer circuitry designs led to the PDP-8 / I and PDP-8 / L in 1968.

When hammerless designs started to become common, the O / U design was introduced, and most modern sporting doubles are O / U designs.

In some cases, it may be unnecessary and / or impractical to expect a designer with a broad multidisciplinary knowledge required for such designs to also have a detailed specialized knowledge of how to produce the product.

Applied engineering is the application of management, design, and technical skills for the design and integration of systems, the execution of new product designs, the improvement of manufacturing processes, and the management and direction of physical and / or technical functions of a firm or organization.

A geotechnical engineer then determines and designs the type of foundations, earthworks, and / or pavement subgrades required for the intended man-made structures to be built.

One of the most successful Soviet designer / inventor in this area was Rostislav Alexeyev who some consider the ' father ' of the modern hydrofoil due to his 1950's era high speed hydrofoil designs.

Since propellant typically represents the majority of the takeoff weight of a rocket, HOTOL was to be considerably smaller than normal pure-rocket designs, roughly the size of a medium-haul airliner such as the McDonnell Douglas DC-9 / MD-80.

Personality theorists argue that by being a creator of something one is inherently at risk and vulnerable for having their ideas and designs stolen and / or altered.

As software became more complex and important, the cost of supporting it on so many different designs became burdensome, and this was one of the factors which led IBM to develop System / 360 and its operating systems.

This removes the need for dedicated I / O instructions, although a drawback in such designs may be that special hardware must be used to insert wait states as peripherals are often slower than memory.

All rowing-machine designs consist of an energy damper or braking mechanism connected to a chain and / or handle.
