Poggi's calculator

In 1937 the problem of automatic solution of linear systems is proposed by Prof. Poggi, University of Pisa, but the entry into war and some resistance in the university prevented the realization of this project and the unit built goes lost.

I'm trying to rebuild this machine for solving algebraic calculations starting from the only sketch left. At the moment there is only a virtual simulation created by Alvaro Gonzalez Firpi.
