Yes, feel free to repost. You may want to check if parity comes up elsewhere. Looking at the Model 1 ROM I see two places where the code may have been changed for the Z-80. Once in the handling of arithmetic operators (+,-,*,/) and another when computing array lookup addresses. In both cases there is an "OR A" before a "JP PO,". I think in the original 8080 version those "OR A" would not have been necessary.
