The Presentation Link Adapter connects either the ViewScreen panel or the TI-Presenter to student calculator featuring the USB port. In 2007 two different Presentation Link Adapters were available:

TI-84 Plus Adapter: Connects to the TI-84 Plus and TI-84 Plus Silver Edition with Cable 1
TI-89 Titanium Adapter: Connects to the TI-89 Titanium with Cable 2

Dismantling the TI-89 Titanium Presentation Adapter reveals a huge surprise, the rather complex printed circuit board (PCB) sports the circuitry of the TI-89 Titanium calculator with its three main components:

Processor: The processor located on the Printed Circuit Board (PCB) is the low-power version of the Motorola MC68EC000 labeled MC68SEC000.

ASIC: This impressive Integrated Circuit with the designation TI-REF680TG0204R02 integrates not only the glue logic of the design and USB interface but even 256k Bytes RAM.

Memory: This Presentation Link Adapter manufactured in August 2005 sports a Sharp Flash ROM LH28F320 with a capacity of 2Mx16 bits.
