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.

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.
