An SBus Monitor Board

During the development of computer peripherals which interface to the processor via the system bus it is often necessary to acquire the signals on the bus at the hardware level. It is difficult to attach general-purpose logic analysers and in-circuit emulators to a multiple pin bus connector and hence it is not practical to catch all the bus datarequired to ensure that such signals are in accordance with the bus specification. Hence a given connector specific bus monitor board is a necessary instrument to attach to the system motherboard in order to monitor all bus activities. A connector specific bus monitor board provides an efficient resource with which to study the internal philosophy of system software, the software implementation process for different communication layers, and to provide debugging for hardware developers. The bus monitor board described here is designed to attach to a SUN SBus and is similar to the Transformable Computer, which appeared recently, in that its arc...
