Campy changed their cable pull in 2001. The upper level 9s is all pre'01, so you can put 9s Chorus and Record on the radar, too, as well as 8s RDs. Probably some other 9s groups, too, but some lower 9s came after '01, and I don't know the visual cues on these.
FWIW, I searched for a while and finally picked up a 9s Chorus off eBay for about $50 shipped after losing many auctions. It works with my 8s Chorus Ergo.
