Selenia Gp-16
The Selenia Gp-16 was a general purpose minicomputer designed by the Italian company Selenia of STET group. It was followed by an upgraded version called Gp-160.
History
The Gp-16 was minicomputer designed mainly for industrial customers, whose concept in design was similar to PDP-8. The design took place in Rome during the mid-sixties under the supervision of Saverio Rotella, when the production was carried in Fusaro (Napoli) in the second half of that decade.[1][2][3]
The most known uses were in control tower in airports, as done in Venice;[4] a modified upgraded version was used in Gruppi Speciali of CSELT, the second electromechanical phone switch in Europe.[5] The Gp16 was later adopted also by Olivetti.[6] However, it never reached a large diffusion because of a small market push from its producing company.[7]
