The electronics of the TI-80 is centered around the Toshiba T6M53AApplication Specific CPU, an ASIC with both an unknown microprocessor and the necessary glue logic to scan the keyboard and control the two different memory chips and the display driver.The graphic display of the TI-80 is connected to a Toshiba T6B79 single-chip display driver mounted on a flexible printed circuit board.

A special "teacher version" called TI-80 VSC combines the standard TI-80 features with a port to connect to a ViewScreen panel via a cable. Placing the panel on the overhead projector enlarges the image of the handheld screen so that each student can follow along.

In 1998 the TI-80 was replaced with the TI-73 sporting an increased display size of 64 * 96 dots for better readable characters and crisper graphs.
