support, normal distribution stat functions (P(), Q(), R()), permutations, combinations, factorials, user-accessible operand registers. However, it added fraction mode display and conversion (pure/mixed), boolean logic operations (NOT, AND, OR, XOR, XNOR) over contemporary TI-35 PLUS/36 SOLAR. It uses the Toshiba T7988 processor. The key and case design was based on contemporary TI-30 SLR, TI-31, TI-32, rather than TI-35/36. It was manufactured by Inventec Corporation in Taiwan.

2004

It was a cosmetic redesign of the 1999 model. Changes include new coloured keys and screen frame. It was manufactured in China.

TI-40 Collège II (1999)

It is a version for Belgium, France and Italy markets. New features over TI-34 II include supports the French fractions. Interface changes include removal of UNIT key. Power source does not include solar panel.

2004

It was a cosmetic redesign of the 1999 model. Changes include new coloured keys and screen frame. It was manufactured by Nam Tai Electronics, Inc. in China for European market.

TI-Collège (2005)

It was based on 2004 version of TI-40 Collège II, but added the ability to use percentage sign (from TI-36X II), engineering notation mode (from TI-36X II), scientific notation conversion. Interface change include the use of French labels on keys and screen. The keys are rearranged so that trigonometrical functions sin, cos and tan are accessible without using menu. It was manufactured by Nam Tai Electronics, Inc. in China for European market.

TI-34 MultiView (2008)

The MultiView series was originally announced with the release of TI-30XS MultiView in 2007. However, design problems caused release delay of the product line to February 2008. It features 96×31 pixel screen, which can fit 4 text lines on screen (5 for menus). MathPrint feature displays mathematical formulae in textbook format. Data editor allow storing up to 3 lists with 42 items per list. The list values are used in statistic modes as sample points. Memory registers were increased to 7. For statistic or constant entry, an expression has a maximum of 47 characters. New mathematical functions over TI-34X II include percentage sign, list conversions. It was manufactured by Nam Tai Electronics, Inc. in China.

TI-Collège Plus (2008)

Following design changes in TI-Collège, the key labels are in French. New features over TI-34 MultiView include Gradian angle mode, Engineering notation mode, scientific notation conversion, median, 25/75-percentile, algebraic factorization, 2x2 linear equation solver, factor decomposition, list generation by function. Features removed from TI-34 MultiView include mixed fraction mode, polar-cartesian conversion pair function, cube/cubic root, ipart(). It was manufactured by Nam Tai Electronics, Inc. in China for European market.

TI-SmartView Collège Plus

It is an emulator for TI-Collège Plus, designed for Windows 2000 and Mac OS X 10.4.

The Educator TI-34 MultiView (2008)

It is a version of TI-34 MultiView sold by Stokes Publishing Company, Inc., designed for overhead projector use. It was manufactured in China.
