Abstract

1296810 Data processing systems R H WILLIAMS 26 July 1971 35461/71 Heading G4A A computer program written in machine code is divided into sections each of which is recorded on replaceable cards for insertion into a read-only memory, each card being provided with a code or number indicating the program content whereby cards may be selected for use by unskilled personel. The cards may have conductive areas for co-operating with coils in the memory or alternative forms not requiring mechanical or electrical contacts to be made may be used.
