The Lick Observatory charge-coupled device /CCD/ and controllerA description is given of a flexible microprocessor-based controller for charge-coupled device two-dimensional detectors. It is noted that the controller can operate under manual control or as a slave to a remote computer linked by coaxial cable. The system is discussed, together with data taken at the telescope and in the laboratory. The flexibility of the controller derives from its modular form and from the use of a programmable 8-bit microprocessor to control and sequence the electronic logic. The electronic circuits for such functions as signal processing, clock sequencing, voltage level adjustment, and temperature control are on small individual plug-in cards, making future improvements and changes simple. The software of the microprocessor is stored in erasable, programmable, read-only memory. Among the limitations of the controller is a scan speed of roughly 35 microsec per pixel.
