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.
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:
(Central processing Unit): The
- 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.
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.
Flash ROM chip
of this Voyage 200
was manufactured by Sharp, Japan. The capacity of the memory chip is 2Mx16 bits, or the equivalent of
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.
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!
(February 2009: Don't miss this TI-XXXXXXXXXXX, you are right: 11 X vs 7 X.)
