SOLVED: For questions 2-3, provide the full MARIE RTN for these new MARIE operations. Include the fetch, decode, operand fetch (if necessary); execution and store result (if necessary) stages. "X" in these instructions means the last 12 bits of the 16-bit instruction and should be referenced as IR[I1.0] in your RTN. Assume there is a direct pathway from MAR to PC (for #3) but not from AC to MAR (#2, after computing the memory location, you have to move it from AC to MBR to MAR).2) ClearIndexed X
