JSR/RTS PRESERVE DELAYED OPERAND AND STACK RETURN CYCLES

MOS manual chapter 8 Example 8.3 defines JSR's six-cycle schedule: opcode, target-low operand, current-stack dummy read, return-high write, return-low write, then the delayed target-high operand read. Example 8.4 defines RTS as opcode, discarded PC+1 read, discarded old-stack read, pulled low and high return bytes, then a discarded read at the raw stacked target before transfer to raw target plus one.

Raw traces, ROM material, local paths, and personal data are not part of this public record.
