Plus and TI-84 Plus Silver Edition with
• 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 labelled 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 Byte RAM.
Memory: This Presentation Link Adapter manufactured in August 2005 sports a Sharp Flash-ROM LH28F320 with a capacity of 2M*16 bits.
