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.
Claims7
Apparatus for loading a sequence of instructions into a memory section of a data processing device comprising:
- a frame;
- address means selectively securable to said frame for providing a plurality of address signals indicative of the selected individual segments of said memory section;
- data means individually and selectively securable to said frame for providing a plurality of data signals in predetermined geometric relationship with selected ones of said address signals, and for providing a visual display indicative of said data signals;
- and
- reading means adapted for translation along said frame for responding to said address and data signal and providing coding signals indicative thereof to said memory section.
