Using the keyplate of the original Little Professor created a

This Little Professor (1978) was manufactured end of 1978
in Abilene, TX (week 36 year 1979) and uses a flexible PCB.

This Little Professor (1978) was manufactured early in 1980
in Abilene, TX (week 03 year 1980) and looks very different.

This PCB of this late Little Professor (week 03 year 1980) uses
the technology of the TI-30.

This picture combines the keyboard layout of the 
Little Professor (1978) with the model introduced in 1980.
