From the technology this Little Professor from
1980 is similar
to the TI-1000 calculator of the same
epoche but uses the smaller keyboard of the slimline LCD-calculators.
The
electronics of this model is identical to the Little
Professor (1978) introduced two years earlier. The picture on the right
compares both printed circuit boards.
Compared to the first version of the Little Professor this one
could easily recognized be at
the ON/OFF keys and the LEVEL-key to adjust the grade level. Compare it your
own with the Little Professor (1976).
Two years later the Little Professor received a LCD instead the
old fashioned LED display. View both versions introduced in the United
States and United Kingdom.
