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,
