You
feel familiar with this Databank? It is nothing else than the electronics of
the TI-2900
Info Bank in the housing of the Europa
10 calculator. It stores 125 names and numbers in a
2k Byte memory. In
addition you an alarm clock with up to 10 alarms, an useful calculator with 10
digits capability and a code protected area for secret informations.
Dismantling
this TI-3400 Europa Databank and comparing with the Europa 10 calculator reveals
a big surprise. The printed circuit boards (PCB's) of both products are
completely different but
carry an identical nameplate "TI-611".
The
Toshiba T9810H Application Specific CPU located in this TI-3400 Europa Databank
manufactured in April 1990 by Inventec
Corporation in Taiwan is known from the TI-3100
Pocket Dialer.
Production of the TI-3400 Europa was shifted to Malaysia early in 1991.
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.
