This grey TI-5130 is identical to the TI-5130 introduced two years earlier. The design changed to the "office grey" of the other 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

The same housing was used two years later again with the TI-5045.

Dismantling this TI-5130 manufactured in 1983 reveals a completely revised printed circuit board (PCB) centered around a NEC uPD1234G single-chip calculator circuit versus the Mitsubishi M58680P chip of the original design.

The design of the TI-5130 was changed in 1985 again to a "brown" design scheme, matching the TI-5140 introduced in the same year.

Texas Instruments introduced already in 1986 with the TI-5130 II the successor of the TI-5130 with a completely different design language.
