First of all we need to consult the dictionary: EUROPA is the German translation of Europe. Texas Instruments introduced the EUROPA-line of products beginning of 1990 as an independent design line for Germany.

Dismantling this EUROPA 10 calculator manufactured in June 1994 by Inventec Corporation in Malaysia reveals a clean design centered around an unknown Toshiba single-chip calculator circuit soldered on a double-sided printed circuit board (PCB) and powered by four solar cells and a small LR54 (LR1130) backup battery.

Please notice that the clock module used with the EUROPA 10 is powered from the calculator electronics, while it used with the similar TI-1798 and BA-20 Profit Manager its own small LR41 battery.

Inspecting the PCB of this EUROPA 10 calculator brought our attention to a small mark reading 10TI611A-02A and revealing the internal TI-611 designation of the product. We spotted similar PCB-Marks already with the TI-1798 and started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.

An identical housing was used for a Databank called simply EUROPA.
