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.

TI-5130_T1285_INT.jpg (272245 Byte)Dismantling this TI-5130 manufactured in December 1985 reveals a design almost identical with the TI-5140.

TI-5130_T1285_PCB.jpg (151240 Byte)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.

TI-5130_T1285_LBL.jpg (41830 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.

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