They... weren't. I'm not aware of them changing, but I probably wouldn't

BSDI used (uses?) an a.out format compatible with NetBSD 0.8 I believe

I think the list would include Dell SVR4, and Coherent Unix as well, but
I didn't want to put them in the list until someone mentioned using
them - since I'm not 'certain'.

That's the good question, but I've re-organized the list to make IBCS2
a sub-list, and BSDI a seperate item. Give it an hour to show up.
