A small microprocessor based CAMAC module for testing and monitoring purposes

Summary form only given, as follows. A small microcomputer, using a Motorola 6800, has been developed. Two printed-board versions have been operating since 1979 in the NA3 experiment, and about 30 other are used for test and small experiments in various laboratories. The computer consists of a 2/25 or 3/25 CAMAC unit, which can be crate controller or branch driver. In normal use, it is connected to SA400 floppy disks and a terminal. Optionally, interfaces to a cassette unit, PROM programmer and three analog outputs can be operated on the same boards. Total memory size is 11 kbytes PROM (22 kbytes with 2716 memories) and 8 kbit RAM. Software on PROM consists of an input-output monitor, with disassembling facility, editor and local assembler, a fast and easy-to-use floppy disk monitor, and an histogram package, in 7 kbytes PROM. Some macro instructions are recognised in the assembler: message printing, CAMAC functions, initialisations and are then very easily performed. (0 refs).
