This early TI-82 with the Date code I-0194 was manufactured
by Inventec in Taiwan in Januaty 1994. 

The PCB (printed circuit board) of the TI-82 manufactured in 1994 looks
very similiar to the TI-81 from the same timeframe.

The main components of the TI-82: Toshiba T84C00 CPU, Toshiba TC14L010 ASIC,
Sharp LH5311993 ROM and Suwa Seikosha SRM2A256 RAM.

Just for reference the main components of a TI-82 with ROM-Version 10.0
manufactured in July 1993 and sporting a  LH5311993 ROM, too.
