NAND outputs tied to ground

They might also have picked which three to use to help present a better transmission line environment to the fast output.  Tektronix did this sort of thing with their own custom ICs to get maximum performance out of leaded packages.

I suspect it may have a non-functional purpose: https://en.wikipedia.org/wiki/Trap_street
