A fault-tolerant computer system comprises a main data bus 10 having interface slots 18 for interconnecting computer sub-systems 12, 14, 16..., one of which is a central processor sub-system 12 having three processor modules 20, 22, 24 operating in parallel in a substantially synchronised manner. One of the processor modules acts as master reading data from and writing data to the main data bus 10: each processor module compares data on the main data bus with data on a local bus of the module to determine any inconsistency indicating a hardware fault, and generates outputs reflecting the probability that a particular module is the source of the fault, which outputs are transmitted to the other modules over a synchronisation bus (26, Fig 3).
