Calculatrum
Calculatrum electronicum (-i, n.)[1][2] sive machinula calculatoria[3] est machina ad numeros calculandos fabricata, saepe gestabilis, quae arithmeticas operationes electrice solvit. A computatro differt, quod programmabile olim non fuit, ac tantum arithmeticas operationes agere poterat.
