A Smart Crate Controller for Fast CAMAC Data Acquisition

A smart CAMAC Crate Controller has been designed for use in Fermilab experiment E-705. Its distinctive feature is a hardwired list processor performing block transfers by executing lists of pre-stored CAMAC instructions. Data collected from the crate are sent to an external port: controllers organized in serial or parallel channels, transmit their data to buffer memories. Processing of interactive CAMAC operations, downloading of CAMAC instruction lists and supervision are provided by a Motorola 6809 micro-processor linked to the controller via the STD bus and to a host computer via an RS-232 serial interface.
