Abstract: A manual crate controller for debugging and testing of CAMAC-modules (CAMAC is an acronym for computer automated measurement and control, an internationally accepted standard for interfacing modular instrumentation with computers through a bused back plane called a dataway) with capabilities for executing a large number of commands with full synchronization in conformity with CAMAC-modes for data exchange, that finds application in minicomputers using the CAMAC-standard. The manual crate controller includes a working and a control station. The latter includes a control panel, a program memory for storing commands entered with keys on the control panel and a start-up logic block. The working station contains a data memory with data inputs connected to the data buses of the CAMAC-main bus, and an input logic with inputs connected to the two most significant buses for function, and to the buses for "BUSY", initiation, resetting, first-strobe and second-strobe of the CAMAC-main bus.
