Mechanical computing devices used in the Istituto (Nazionale) per le Applicazioni del Calcolo "Mauro Picone"

Indice

1 History

The "Istituto per le Applicazioni del Calcolo" M. Picone (IAC) is a major Research Institute in Applied Mathematics of the Italian CNR.
Its history goes back to 1927 when it was founded by Mauro Picone. Since the origin its mission is to develop advanced computational methods -based on a rigorous mathematical approach - to give a numerical affordable solution to problems with strong relevance to science, society and industry.
As obvious consequence, IAC owned a wide variety of mechanical computing devices, from the first Brunsvigas until FINAC, one of two first electronic computers installed in Italy in 1956. In 50es IAC was chosen by UNESCO as siege of his International Computing Center.
Thanks to documents kept in personal Picone's archive, I've been able to built the following tables containing valuable data about almost all machines used in the institute.

3 MADAS

This is a quite confused chapter. Picone was not satisfied by MADAS's reliability. Machines was often upgraded or changed. Often two descriptive nouns (E.G. XX-DZ and XX-eDLZ) refer to the same serial number.
