Changes
/* Instruction Execution Sequence */
*T1: Fetch operand byte $42 (zero page pointer address)
*T2: Get low byte from zero page ($80)
*T3: Get high byte from next zero page location ($10) in the first half-cycle, then add Y-register value ($F1) to $1080
*T4: Handle page boundary crossing (since $1080 + $F1 crosses a page)
*T5: Read the value from memory address $1171 into the accumulator
