Sorry for not noticing this earlier, but the signal S0 seems to be
missing on the 6509. I added it myself and moved around the layout a
bit to fit SO2 where the other control signals are. (I also sorted it
by pin number. Never used the library editor in KiCad before so I just
edited the text file directly):
