Abstract: A method and apparatus for programming microprocessors which require machine code program instructions wherein black and white code strips are selectively pasted on a sequential instruction frame along a preprinted address code column, each code strip including a parallel trailer wherein the english equivalent of the instruction is displayed. A photoelecric, parallel reader is mounted on the frame for translation across the frame to sequentially load both the address code and the pasted on binary coded instructions into a static random access memory chip for the microprocessor. The technique thus provides for selective alteration of such program sequences by removing selected instruction strips and replacing such strips with other coded strips as required to modify the routine.
