The CP1600 was a 16-bit microprocessor created in a partnership between General Instrument and Honeywell in the 1970s. The CP1600's design was based on the PDP-11, whose design also formed the basis of the Western Digital MCP-1600 and influenced others. Honeywell used the CP1600 in a number of process control computers and related systems, but its most widespread use was the CP1610 version in the Intellivision video game console.
