Obviously a typing mistake :-) here are some more timings for PUSH/POP: PUSH qq (5,3,3) Standard =11Ts PUSH qq (5+3,3+1,3+1) RAM contention =16Ts PUSH qq (5+3,3+5,3+5) Display contention =24Ts POP qq (4,3,3) Standard = 10Ts POP qq (4,3+1,3+1) RAM contention =12Ts POP qq (4+4,3+5,3+5) Display contention =24Ts Edwin
