The TI-89 Titanium VSC uses a redesigned bottom shell of the housing to accommodate the ViewScreen connector. 
This calculator with the date-code I-0709 was manufactured by Inventec in Shanghai, China in July 2009.

A small, carefully shielded PCB (printed circuit board) hosts some drivers between
the ViewScreen connector and the flexible cable reaching to the main PCB.
