I recall that one. It has some logic-race bugs.


May well be. Why don't you enumerate them? Be precise. This is
supposed to be what this group is all about.


The AC line is sufficiently nasty (noise, distortion, phase and
amplitude hits) that a precision zcd doesn't make a lot of sense. What
makes sense is something that is safe, simple, and reliable.
