The TI-5021 was introduced in the year 1988 and combined a huge 12-digit display, a convenient keyboard and a small clock in a stylish desktop style housing. Instead the huge solar cells of the TI-5020 this one uses a single AA-sized battery for both calculator and clock module.

The TI-5021 addresses both home and office use and features even an item counter [IC] key and margin up/down [MU/D] functions.
