Abstract : This report contains a description of the most salient features and modifications which were implemented in the RADC M555 software system. All changes to ECP-2 were made either to protect certain programs or data vital to the successful operation of the system or to provide a greater degree of flexibility in the use of the system. Most important were the various protection features that were added such as the Map and Indicator block protection and checksumming, system disc file lockout capability, and removal of unessential interrupt lockout enables.
