Machine Language / Assembler Test Programs

Format: The simulator expects the first line to contain the name of the program and the second line the contain the starting address (initial IP value). Subsequent lines contain the machine language code (what is to be loaded into memory) starting with location 0. Only the leading, numeric part of each line is used by the simulator. The rest (assembler and comments) is for human consumptions only. If there is more than the machine code, it must be immediately followed by at least one blank.
