In opposite to the first printing models like the TI-5040 and TI-5135 this one was manufactured in Japan. The basic functions are similar, the technology inside completely different.

This calculator was available either with display or without (TI-5120). A sibbling of the TI-5130 with 12-digits printing capability was introduced in two steps. The first TI-5142 with a totally different styling and within month the final TI-5142.

TI-5130_LBL.jpg (42999 Byte)Since we deciphered the product label of the TI-5310 matching the UL-File number E42662 with a identification code 694B, we know with Toshiba TEC Corp. the manufacturer of this calculator, too.

Don't miss the database of all known UL-File numbers found on Texas Instruments calculators.

In 1983 Texas Instruments changed the design line again to the "office grey" coloring schema of other office products. The desktop line then covered 6 different calculators:

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

About 7 years later TI introduced a paperless printer. Please visit the TI-5038.

The TI-5130 is featured in the Texas Instruments Incorporated leaflet CL-199M dated 1983.
