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.
