Texas
Instruments introduced in the United States with the BA-20 a very useful calculator.
Beside the basic calculator functions 6 additional keys enable the COST, SELL,
MARGIN calculations. You enter either two of the variables and get instantly the
result of the remaining value.
Both
the housing and the clock module were used with this TI-1798 and its European
sibbling TI-610.
Please notice the TI-1796 designation on the printed circuit
board (PCB), a hint that leads into the wrong direction.
The next generation of the TI-1798
looks completely different.
