The
TI-44 sold in Europe is 100% identically to the TI Business Analyst-II sold
elsewhere. Find more information on the Business
Analyst-II page. The calculator was available till the year 1984 and then
replaced with the BA-II.
The
internal construction of the TI-44 is more or less identical with the TI-1030
introduced June, 1978. The whole calculator uses one flexible printed circuit board
(Flex-PCB) with the integrated
circuit and a LCD-module. You won't find any soldering or usage of screws within
the calculator.
Like
the TI-30 LCD the TI-44 was available long time and
received some minor redesigns during production time. Late models make use of a
TP0322 in a smaller package.
