ABSTRACT:
A computer having a main read only memory is so arranged that a portion of the information stored in the main read only memory can be changed, if desired, without changing the entire main memory. Information to be substituted for a portion of the main information contained in the main memory is stored in a correction memory, which is incorporated in the computer when required. The CPU is arranged to fetch and use instructions or data alternatively from the main memory or the correction memory in such a manner that a predetermined portion of the main information is replaced by the substitute information. In one embodiment, data is stored in the correction memory for designating which portion is to be replaced and the CPU selects either memory depending upon this data. In another embodiment, one or more comparators are used for comparing the value on an address bus with addresses for designating the start and the end of the portion to be replaced.
