Dismantling this TI ViewScreen 82 with
Date code LTA93 manufactured in October 1993 by
Texas Instruments in their Lubbock, TX, facility
reveals no surprises and looks almost identical to the final design introduced
in 2004 and in production till 2008. A large, transmissive LCD panel is connected to a Toshiba
T6A04 display driver known already
from the redesigned TI-81 introduced in October 1993,
too. The reminder

The Toshiba T6A04 combines 120 column drivers and 64 row drivers and the display RAM with a capacity of 120 x 64 bits in a tiny tape carrier package (TCP) and connects directly to an 8-bit Interface.
The Presentation Link Adapter connects the student versions of the TI-84 Plus family to the ViewScreen panel using the calculator's USB port.
With the phase out of the overhead projectors from the daily life, Texas Instruments developed with the TI-Presenter a perfect replacement for the ViewScreen panels based on modern video technology.
