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 32-bit microcomputer, a full ASCII keyboard, a wide graphics screen and tons of built in software. Since then the basic design received two upgrades:
 | TI-92 II: Five user languages
and doubled RAM capacity |
| TI-92 Plus: Flash-ROM technology |
The printed circuit board
(PCB) of the Voyage 200 makes use of the TI-92 Plus hardware but doubles the
capacity of the Flash-ROM from 2M*8 to 4M*8.
Beside the MC68000
compatible microcomputer, two 128k*8 RAM and the Flash-ROM you'll notice only the display drivers
T6B07 (3*column)
and T6B08 (2*row).
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 we never discovered a nameplate without the leading TI-xx designation.
Even the engineers of Texas Instruments were surprised when marketing decided
for the unusual Voyage 200 name !
