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.
Dismantling
this early TI-5130 manufactured in 1982 reveals a very clean design.
The
printed circuit board (PCB) of the first generation TI-5130 is centered around a
Mitsubishi M58680P single-chip microcomputer.
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:
About 7 years later TI introduced a paperless printer. Please visit the TI-5038.
