The TI-5020 was introduced in 1983 and and got the then new grey-blue design.  

The desktop line then covered 6 different calculators:

TI-5008    Pocket-sized, thermal printing
TI-5010    Small-sized, standard paper
TI-5032    Desktop-sized, battery option
TI-5130    10-digits, standard paper
TI-5142-III 12-digits, standard paper
TI-5020    Non-printing, solar powered

In the same timeframe a similar housing was used with the TI-5100 II. In 1988 the TI-5021 introduced a 12-digit display and included even a clock module.

The TI-5022 sports a 12-digit display in an otherwise identical housing.

The plastic material used for the housing of the TI-5020 is very sensitive to direct sun exposure. Find a picture of a heavily used calculator. 



The TI-5020 is featured in the Texas Instruments Incorporated bulletin CL-823A dated 1985.
