This TI-5140 was manufactured in December 1985 in Japan. The style of the label and
the leading "T" in the date code suggests one of Toshiba's assembly plants. 

The internal design of the TI-5130 is very clean and cost effective.
Please notice the 10-digit display and the printer with 12 drums. 

The printed circuit board (PCB) of the TI-5130 is centered around a 
NEC uPD1234G single-chip calculator circuit.
