IBM 1710

The IBM 1710 was a Process Control system that IBM marketed in the 1960s. It used either a 1620 I or a 1620 II Computer and specialized I/O devices (e.g., A/D Converter, D/A Converter, Discrete I/O, Operator control panels).

The IBM 1620 used in the 1710 system was modified in several ways, the most obvious was the addition of a very primitive hardware interrupt mechanism.

The 1710 was used by many paper mills[?] and oil refineries.
