The peculiar characteristics of an autonomous CAMAC system based on the use of an Intel 8080 microprocessor are described. The system memory for program store, scratch work and data acquisition is contained in the autonomous CAMAC controller. Memory can be accessed in DMA mode with 24-bit data utilizing three bytes with a unique address. Suitable 3-byte floating point mathematical subroutines have been developed for general use and in particular for the requirements of the system. Details on hardware and software of the system are illustrated together with a brief mention of the generalizations.
