The CII 10070 is a discontinued computer system from the French company
CII. It was part of the first series of computers manufactured in the late 1960s under
Plan Calcul
Plan Calcul was a French governmental program to promote a national or European computer industry and associated research and education activities.

The 10070 served as the basis for the design of the
Iris 50 and
Iris 80 series, which were entirely manufactured by CII.
