The first edition of the TI-52 was manufactured in Japan. Please notice the two rigid printed circuit boards (PCB's),
a smaller one for the display and the Toshiba single-chip calculator circuit and a larger one for the keyboard.
The two coin-type batteries are orientated in east-west direction.

The second edition of the TI-52 was manufactured in Italy. The internal construction is totally different and
uses a two-sided flexible board. We know this type of design already from other calculators like the TI-30.
The two coin-type batteries are orientated in north-south direction.
