Abstract
A fault tolerant computer system has a central processing system which includes at least one set of data pathways, and executes a series of data processing instructions including the transfer of messages along the plurality of data pathways. At least one set of transaction data storage devices are coupled to the data pathways for storing a predetermined number of successive messages transferred most recently on the data pathways. Error checking devices are included for detecting the presence of errors in the central processing system. Error storage devices are coupled to the transaction data storage devices and the error checking devices for causing the transaction data storage devices to cease storing additional messages in response to the detection of errors by the error checking device.
