The display of the TI-80 is somewhat boring with 
only 48*64 dots to show 8 lines of 16 characters.

The printed circuit board (PCB) of the TI-80 with
just an application specific Z80 CPU with one
external RAM and one ROM. The LCD-Driver
is placed on a small flexible board.


The battery compartment with only two CR2032
Lithium batteries instead the 4+1 batteries of
the other graphing calculators.
