Texas
Instruments replaced in France the original TI-Collège
Plus in 2013 with this TI-Collège Plus Solaire sporting the design of the
TI-34 MultiView introduced already in 2008.
The TI-Collège Plus
Solaire features a dot
matrix display with 31 * 96 addressable pixels allowing the calculator to
display equations as they would be printed in a text book.
The TI-Collège Plus
is the first calculator in the new MultiView series sporting for the "mode
menue" a total of 5 lines by 19 characters on the small graphing screen.
Both the TI-30XS MultiView
and the TI-34 MultiView used just 4 lines.
In addition to this
so called "AFFNATUREL / MathPrint" mode the calculator sports a TI-Collège compatible "AFFLIGNE
/ Classic" mode.
Compared with the original TI-Collège, we notice some major improvements:
| •
AFFLIGNE (compatible with TI-Collège) and AFFNATUREL Mode • EOS with 8 pending operations and 23 levels of parentheses • 7 memory variables x, y, z, t, a, b, c • Data editor and list formulas: 3 lists, each up to 42 items • Function table • Toggle key fractions and decimals • Equation entries up to 80 digits |
Dismantling this TI-Collège Plus
Solaire with the serial number K-DVT-239 (K for
Kinpo electronics, Inc. and DVT
for Design Validation Test) reveals a pretty common
construction with two printed circuit boards (PCB's). The main PCB hides the
single-chip calculating circuit under a small protection blob of black epoxy and
drives the graphing display with a heat sealed fine-pitch connector. The
keyboard makes use of a much simpler second PCB and a heat sealed connector,
too.
