From the technology this Little Professor from
1980 is similar
to the TI-1000 calculator of the same
epoch but uses the smaller keyboard of the
TI-1010 slimline LCD-calculators.
The internal design of this Little Professor (1980) is more or less identical to the second iteration of the Little Professor (1978) introduced two years earlier. The picture on the right compares both printed circuit boards (PCBs).
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.
