This early TI-52 Prototype was manufactured in April 1985 by Toshiba in Japan. |
The
battery holder of this early TI-52 Prototype is identical with the
TI-30 Galaxy. |
The first design of the
TI-52 makes use of two printed circuit boards
(PCB's). The smaller PCB accommodates the single-chip calculator circuit, the display and the battery contacts. The larger one just the keyboard. |
