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.
Four ViewScreen panels were available in 2008:
|• Panel 1:
TI-73 VSC, TI-73 Explorer VSC,
TI-82 VSC, TI-83 VSC,
TI-83 Plus VSC, TI-83 Plus Silver Edition VSC, TI-84 Plus VSC,
TI-84 Plus Silver Edition VSC
• Panel 2: TI-89 VSC, TI-89 Titanium VSC, TI-92, TI-92 Plus, Voyage 200
• Panel 3: TI-85 VSC (2nd design), TI-86 VSC
• Panel 4: TI-Nspire, TI-Nspire CAS, TI-Nspire Touchpad, TI-Nspire CAS Touchpad
As an alternative the TI-Presenter video adapter connects to a TV or other projection device with a video input port.
a technical point of view the TI-83 VSC is almost identical with the students
TI-83. The main difference you notice is a bulgier bottom shell of the
calculator housing to accommodate the ViewScreen electronics and connector. Dismantling
the TI-83 VSC reveals a small printed circuit board (PCB) with two driver chips
connected with a flexible cable to the display PCB of the calculator.
Disassembling this TI-83 manufactured in June 1996 by Inventec Corporation in Taiwan reveals no big surprises. It makes use of just 5 main components on the printed circuit boards (PCBs):
|• 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 T6A04 - display driver
glue logic of the TI-83 is integrated into a Toshiba TC14L010 ASIC, known
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 T6A04 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.
Don't miss the colorful slide cases developed for the TI-83 Plus, they fit on the TI-83 ViewScreen, too.
The design of the TI-83 VSC was changed shortly after the introduction of the TI-73, find the official statement from Texas Instruments' website below:
|The slightly different look of the popular
TI-82 and TI-83 graphing calculators is in response to the very positive
educator reaction to the design, display viewability and rugged
construction of the new TI-73 middle grades graphing calculator.
Appearance changes to the TI-83 are limited to rounder key shapes and a
raised display. The TI-82 change is more dramatic, as the product looks
much rounder than the original boxy style. The key shapes for the TI-82
are also rounded.
