This "brown" TI-5130 is identical to the "office grey" TI-5130 introduced two years earlier. It matches perfectly its sibbling TI-5140 sporting a 12-digit display.
Dismantling
this TI-5130 manufactured in December 1985 reveals a design almost identical
with the TI-5140.
The
main differences are the NEC uPD1234G single-chip calculator circuit and the
10-digit display compared to the uPD1231G chip driving a 12-digit display.
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.
Texas Instruments introduced already in 1986 with the TI-5130 II the successor of the TI-5130 with a completely different design language.
