Honeywell 316

The Honeywell 316 was a popular 16-bit minicomputer built by Honeywell starting in 1969. It is part of the Series 16 which includes the Models 116, 316, 416, 516 and 716. They were commonly used for data acquisition and control, remote message concentration, clinical laboratory systems and time-sharing. The Series 16 computers are all based on the DDP-116 designed by Gardner Hendrie at Computer Control Company, Inc. (3C) in 1964.

The H-316 was used by Charles H. Moore to develop the first complete, stand-alone implementation of Forth at NRAO. They were used as ARPANET Interface Message Processors (IMP) but could also be configured as a Terminal IMP (TIP) which added support for up to 63 Teletype machines through a multi-line controller.

The original Prime computers were designed to be compatible with the Series 16 minicomputers.

The Honeywell 316 also had industrial applications. A 316 was used at Bradwell nuclear power station in Essex as the primary reactor temperature monitoring computer until summer 2000, when the internal 160k disk failed. Two PDP-11/70s, which had previously been secondary monitors, were moved to primary.
