Yes, I suppose you're right. It's much nicer (IMO) to do the full
trick by asserting /WAIT with /M1, a flip-flop, AND a debounced

single-stepping circuit for a Z80 is pretty simple.
True, but it is not quite as simple as hooking up a debounced pushbutton
to the clock, which was how I interpreted the OP's question.
