The original design of the TI-30 introduced two years earlier was slightly changed to fit with the TI-30 STAT. Please notice the yellow or white printing of the "TEXAS INSTRUMENTS" logo above the keyboard on both TI-30 designs

A total of four different versions could be found here.

TI-30_1988_PCB.jpg (71843 Byte)The picture on the right gives you an idea about the internal construction of the calculator. The flexible printed circuit board (PCB) forms one half of the keys, holds the calculator chip and connects to the LCD. Even the two coin batteries are connected directly with two small PCB parts. Find a similar construction with the TI-52.
