Prompted by an entry in this list, I tried switching Z-80 processors. Lo and behold!! The Problem Of The Lost Flags goes away! This is all very well, but then when I try the original Z-80 in another machine (same board), it performs correctly! Where did the Lost Flag problem go? Could dirty pins cause me to lose status flags while tracing in DDT? Oh well, I'll file this one along with the other intermittent problems I'm often plagued with.... ~sigh~ Bruce Robertson
