The
TI-83 ViewScreen Calculator (VSC) is the teacher version of the standard TI-83.
It connects with a special port to a ViewScreen panel via a cable. Placing
the panel on the overhead projector enlarges the image of the handheld screen so
that each student can follow along.
Three ViewScreen panels were available in 2003:
 | Panel 1: TI-73 Explorer VSC, TI-80 VSC,
TI-82 VSC, TI-83 VSC, TI-83 Plus VSC, TI-83 Plus Silver Edition VSC |
| Panel 2: TI-89 VSC, TI-92, TI-92 Plus, Voyage 200 |
| Panel 3: TI-85 VSC, TI-86 VSC |
As an alternative the TI-Presenter video adapter connects to a TV or other projection device with a video input port.
From
a technical point of view the TI-83 VSC is almost identical with the students
TI-83. The first difference you notice is a slightly changed bottom shell of the
calculator housing to accommodate the ViewScreen connector.
Dismantling
the TI-83 VSC reveals a small printed circuit board (PCB) with two driver chips
connected in a piggy back manner to the display board of the calculator.
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.
