The
TI-5027 II replaced the almost identical TI-5027
within one year and features a much larger display. The calculator is still
battery operated.
The
label on the backside of the TI-5027 II looks familiar to us, the leading
"T" of the date code suggests Toshiba as manufacturer.
Dismantling
the calculator reveals its true genes, it was indeed developed and
manufactured by Toshiba in Japan. Please notice the Toshiba printed on the printed circuit board (PCB) of the calculator.
The next medium sized desktop calculator in the line was the TI-5032.
