| The display
of the TI-80 is very difficult to read with only 48*64 dots to show 8 lines of 16 characters.
|
| This
TI-80 with the Date code I-1296 was manufactured
by Inventec in Taiwan in December 1996. Please notice the battery compartment with only two CR2032 Lithium batteries instead the 4+1 batteries of the other graphing calculators.

| The
printed circuit board (PCB) of the TI-80 reduced the number of components dramatically compared with its sibblings.
|
| The main
components of the TI-80: Toshiba T6M53A Application Specific CPU, Sharp LH5359@1995 ROM and Suwa Seikosha SRM2264 RAM.
