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.
The
internal construction of the TI-5021 is based on the Toshiba T6897 single-chip
calculator circuit and a self contained clock module.
In 1993 a more or less identical calculator was introduced
with the TI-5021 SuperView™.
The design of the TI-5021 matches with the TI-5038 introduced in the same year.
