Subj: REPLY TO MSG #5332 (UNDOCUMENTED 80C85 OPCODES)
I have no idea what bit 3 of the status byte is for, so anything you could add to my knowledge here would be ideal. The V flag is bit 1. The undocumented opcodes including RST V were written up, I believe, in the September 1980 edition of Microcomputing, in an article called "The Secret Life of the 8085" by Ken Barbier.
