This TI-83 Plus with the date code I-0799A was manufactured by Inventec in Taiwan in July 1999.

The main printed circuit board (PCB) of the TI-83 Plus manufactured in 1999 is completely different to the 
previous TI-83. The Toshiba T6C79 Application Specific CPU was replaced by a two-chip approach based on
a discrete Zilog Z-80 CPU and a Texas Instruments TI REF 9815455 ASIC.

The PCB of this TI-83 Plus manufactured in Summer 1999 with the classic Z-80 based architecture. The
Flash-ROM AM 29F400 stores up to 512k Byte Program and the S-RAM Epson SRM2B256 sports 32k Byte capacity.

This early TI-83 Plus hosts the original ASIC TI REF 9815455 in a standard flatpack housing.
