Abstract
A data processing system comprising a central processing unit, a read-only memory, a changeable read-only memory and a read-write memory. A resident computer program is stored in the read-only memory, and instructions corresponding to program changes are stored in the changeable read-only memory. The program is assembled, revised and stored in the read-write memory from which the revised program can then be executed by the central processing unit. Other or further program revisions may be made by changing or reprogramming the changeable read-only memory.
