Voyage200_Back.jpg (284461 Byte)At first glance the stylish Voyage 200 looks like a modern and innovative Symbolic calculator. Dismantling the calculator reveals a 6 years old design in new clothes!

We wrote January 5, 1996 when Texas Instruments released with the TI-92 their first Symbolic calculator using a powerful 16/32-bit microcomputer, a full ASCII keyboard, a wide graphics screen and tons of built in software. The TI-92 received since its introduction two upgrades:

TI-92 II: Language selectable Operating System and 128k Bytes additional User memory.

TI-92 Plus: Flash ROM technology for re-programmable Operating System and downloadable applications.

Voyage200_PCB.jpg (177042 Byte)The printed circuit board (PCB) of this early Voyage 200 manufactured in June 2002 makes use of the TI-92 Plus hardware, but doubles the capacity of the Sharp LH28F320 Flash ROM from 1Mx16 Bits (2M Bytes) to 2Mx16 bits (4M Bytes).

The main components of the featured Voyage 200 manufactured in June 2002:

Voyage200_ASIC.jpg (169957 Byte)Voyage200_CPU.jpg (120941 Byte)CPU (Central processing Unit): The Motorola MC68SEC000 - the original M68000 16/32-bit microprocessor introduced in 1979 - optimized for embedded applications is supported by the TI-REF 200C040 and replaces the Application Specific CPU SC414181 solution if the TI-92. Learn more about the Hardware Architecture of TI’s Graphing Calculators.

Voyage200_ROM.jpg (170534 Byte)ROM (Read Only Memory): The ROM contains the operating system of the calculator. The first products on the market used mask-programmable ROM, the program was stored already during the production of the Integrated Circuit. Later calculators changed to Flash ROM, a technology allowing the programming of the software during the final production stage of the calculator. With the TI-83 Plus and all later graphing calculators from Texas Instruments even the user was able to reprogram the operating system.

The Flash ROM chip LH28F320 of this Voyage 200 was manufactured by Sharp, Japan. The capacity of the memory chip is 2Mx16 bits, or the equivalent of 4M Bytes.  

Voyage200_RAM.jpg (111586 Byte)RAM (Random Access Memory): The RAM is used as data memory and is used to store both variables, user programs and intermediate results. This Voyage 200 makes use of two Static RAM chips CY62126 manufactured by Cypress, USA. The capacity of the memory chips is 128k Bytes, each.

Voyage200_LCC.jpg (285253 Byte)DISPLAY: The Voyage 200 uses - in opposite to the handheld graphing calculators from this era - display drivers in conventional packages. We noticed in this Voyage 200 three T6B07 column drivers and two T6B08 row drivers manufactured by Toshiba, Japan. 


A serial port of the calculators allows the connection to the Calculator-Based Laboratory system CBL, its successor CBL 2 and the Calculator-Based Ranger CBR. Texas Instruments announced June 2002 an optional full-sized QWERTY Keyboard for a more convenient entry of notes into the handhelds but it even matched the Voyage 200.

Within the long history of TI calculators between 1972 (the famous Datamath) and today (June 2003) we never discovered a nameplate without the leading TI-XXXXXXX designation. Even the engineers of Texas Instruments were surprised when marketing decided for the unusual Voyage 200 name!

TI-XXXXXXXXXXX, you are right: 11 X vs 7 X.)

DALLAS, January 6, 2002

Texas Instruments, the leader in handheld educational technology, today announced the launch of its newest educational handheld, the Voyage™ 200 Graphing Handheld. With an icon desktop, computer connectivity, and multi-curricular software applications, this learning tool offers students a powerful handheld for understanding mathematics that can also be used in other subject areas.

Developed with leading educators, Voyage 200 combines all of the functionality and three times the user-available Flash memory of the popular TI-92 Plus, a graphing tool for high school and college advanced math. The unit comes equipped with an icon desktop, which enables users to easily navigate among Handheld Software Applications (Apps). It has a large screen display with 128 by 240 pixel imaging, and features an ergonomically designed case and a QWERTY keypad for note taking.

"I've used Texas Instruments technology in my classroom for many years, starting with the TI-81, and have always been impressed with how TI listens to educators during the development of new products," said Ann Davidian, a mathematics teacher from General Douglas MacArthur High School in Levittown, New York. "I'm excited about being a pilot site for Voyage 200 because I think it greatly expands the possibilities of what I can do with a handheld. My students think it's amazing and say the Voyage 200 would be the only handheld they would need for all of their classes."
