Which brought me to ask why do we use SEI in the first place? The 6507 has no interrupt capabilities (aside from BRK and the timer interrupt at $285), right. So it seems like putting SEI in your code wastes a byte. So should CLEAN_START remove it too?
If this has been asked before then please excuse me. I searched the list and couldn't find anything. Then again the search process doesn't seem to be working very well.
Take care,
Dennis
