(Didn???t Ultrix for VAX use ECOFF?) I'm pretty sure Ultrix on VAX was a.out. It could certainly run 4.2BSD a.out binaries. It did have some kind of SVR2 or SVR3 compatibility mode and it's possible that could run COFF binaries. I don't think I've seen ECOFF anywhere but on MIPS. Were there any SVR4 ports that didn't use ELF? The AT&T spinout where I saw and briefly used the VAX running SVR4 also had a bunch of 3B20s and I think 3B15s, but aside from noticing that they were all powered from the overhead 48V busbars and that the VAX must have been a real nuisance for their electricians, I never did anything with those.
