DATAMATH CALCULATOR MUSEUM
|The Little Professor (1985)
educational calculator in its package.
|This Little Professor was manufactured
in October 1974
by Texas Instruments in Lubbock, TX (week 43 year 1986).
|The flexible printed
circuit board (Flex-PCB) of the Little Professor (1985)
combines display, single-chip calculator circuit and keyboard.
|The component side of the
PCB looks pretty familiar to us. It uses the
technology introduced in 1978 with the TI-50 calculator.
