Why yes it does!. Just keep in mind that between 4.3 and 4.4 the virtual memory subsystem greatly changed, and as far as I know never was ported to the VAX. It may be easier to revert NetBSD 1.2 into 4.4 ….

But with all that work, well… It’s easier to just boot NetBSD.

Yeah. That set.
Does 4.3BSD-Tahoe have a VAX port?
Can’t we just try and make everything jump off of that?

The four CD set? I have those as well.

What we don’t have is any way to run the old pure 4.4

I’m almost surprised there is no Tahoe emulator of some kind.

I have the full source.
For all the BSD distros.
I have the CSRG archives.
You want?

I think this is the full 4.4 BSD source code.

I never did check why/how the VAX port of BSD fell behind from 4.3 BSD to 4.4, Net/2, 386 BSD, NetBSD 0.8/0.9/1.0 …
