The Little Professor introduced in 1980 uses a small keyboard 
to fit alle 5 keyrows in the limited space of the original keyplate. 
The key spacing is identical to the TI-1010 keyboard.

The printed circuit boards (PCB's) of the Little Professor manufacturedin 1978 (left) and 1980 (right)
are identical. The smaller keyboard of the later Little Professor is obvious.
