A fault tolerant computer system includes a fault tolerant data processing module which has means for detecting and correcting errors in the operation of the data processing module to maintain a high degree of data integrity. Data transmission control devices control the transmission of all data to the fault tolerant data processing module and the receipt of all data into the fault tolerant data processing module. Input/output terminals are coupled to the data transmission control means for receiving and transmitting data. A non-fault tolerant input/output module is coupled to transmit the data to the input/output terminals of the fault tolerant data processing module. This module includes a read device for transferring data to the fault tolerant computing system in response to requests from the data transmission control devices, and a firewall for preventing the non-fault tolerant input/output module from initiating transfers of data to the fault tolerant data processing module.
