Following the introduction of Universal Controller parts for the Basic Controller, Honeywell introduced this limited version of the original Hiway processor card.

This processor will not work in the Basic Controller, RCD, or PIUs, but was intended for service in the following boxes: Basic and Enhanced Operator Stations.

This card contains the microprocesor that does the processing for the Operator Station. A single red LED on the card edge is illuminated when the processor is running.

The original, unconstrained version of this processor, the 30731832-001, is still available from WPC, and can be used in the Basic Controller in addition to the boxes listed above.
