You
feel familiar with this TI-3400 EUROPA Databank? It is nothing else than the electronics of
the TI-2900
Info Bank stuffed into the housing of the EUROPA
10 calculator. It stores 125 names and numbers in a
2k Byte memory. In
addition it features an alarm clock with up to 10 alarms, an useful calculator with 10
digits capability and a code protected area for secret information.
Dismantling
this TI-3400 EUROPA Databank manufactured in April 1990 by
Inventec Corporation in Taiwan
reveals a clean design with an almost empty double-sided printed circuit board
(PCB) powered by a small CR2025 lithium battery. The Toshiba T9810H Application Specific CPU located with this TI-3400 EUROPA Databank is known from the
TI-2900 Info Bank and TI-3100 Pocket Dialer.
Inspecting
the PCB of this TI-3400 EUROPA calculator brought our attention to a small mark reading
10TI611DAMB-31D and revealing the internal TI-611 designation of the
product. We spotted similar PCB-Marks already with the EUROPA 10 and started compiling a list of the
PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
Production of the TI-3400 EUROPA was shifted early in 1991 to Malaysia.
Texas Instruments launched in 1987 a very innovative product line with the TI-2400 Phone Bank, TI-2600 Personal Banker, TI-2700 Mini Data Bank, and TI-2800 Paperless Printer followed till 1990 with the TI-2100 Pocket Info, TI-2900 Info Bank, TI-3100 Pocket Dialer, TI-3200 Pro Dialer, and TI-3400 EUROPA.
If you know the history of Texas Instruments it seems to
commemorate the introduction of the TI-2500
Datamath a quarter century ago.
