About
six years after introduction of the original TI-82
the calculator received a restyling to match with the current design line. The TI-82 offers a basic set of graphing tools for
mathematics and science coursework. The TI-82 is together with the TI-83
the predecessor of the upgradeable
TI-83 Plus.
From
a technical point of view resembles this TI-82 manufactured in 2000 more or less
the original design introduced in 1993. The printed circuit board (PCB) looks
very similar to the first design and makes use of the same components:
| • Z80 microprocessor • Toshiba TC14L010 ASIC with glue logic • Sharp LH531©1995 - Mask ROM for internal program storage • Samsung KM62256 - 32k Bytes SRAM for user program and data • Toshiba T6A04A - display driver |
The
glue logic of the TI-82 is integrated into a Toshiba TC14L010 ASIC, known
already from
the first edition of the TI-82. Learn more about the
Hardware Architecture of TI’s Graphing Calculators.
A
deeper exploration of the display board shows the unbelievable high density of
electrical connections between the Toshiba T6A04A display controller and the
graphics screen.
A serial port of the calculators allows the connection to the Calculator-Based Laboratory system CBL, its successor CBL 2, the Calculator-Based Ranger CBR and its successor CBR 2.
In 2001 another styling variation appeared, don't miss the TI-82 Parcus.
