The TI-5140 printing desktop calculator was introduced in 1985 and fits neatly into the TI-5130 series started already in 1981.
this TI-5140 manufactured in June 1986 reveals a design almost identical with
The main differences are the NEC uPD1231G single-chip calculator circuit and the 12-digit display compared to the uPD1234G chip driving a 10-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.
