I vaguely recall that there was at least one NetBSD version that was just
broken and hadn't been tested on any VAX (real or simulated) before it was
'released'.
I suggest you:
1) try the same with simh 3.9
2) try a later NetBSD release.
If you're seeing a problem which persists across several NetBSD releases,
and/or exists in the 4.0 code but not the 3.9 code, please open an issue at
https://github.com/simh/simh/issues
Have Fun.

Thanks for the tips and info.
I've tried all versions of NetBSD 5.x (5.0.2, 5.1, 5.1.5, 5.2 and
5.2.3) that I can find on SIMH 4.0 beta and they all Segv. I have an old
NetBSD 3 that boots and I tried NetBSD 6.0.4 and that also boots.
I am not able to run earlier versions of SIMH as I'm on Windows 10 64-bit
and WinPCAP does not run on W10. I use NPcap on W10 and that doesn't
work on earlier versions of SIMH which require WinPcap.
You shouldn't need WinPCAP merely to test if the CD image is bootable.
The point of the boot test exercise is to help determine if the problem is
in NetBSD or due to recent changes to simh. If changes to simh are at
fault, I'll track it down and fix the problem.
I specifically want to run a 5.x version of NetBSD. I'm pretty sure it did
run on SIMH 3.8-1 on Windows 7 before the upgrade. I need to downgrade a
laptop I have to Win7 in the future and may try that. Until then I'll play
with OpenBSD which doesn't seem to have any problems with SIMH 4.0 beta.
The boot test I'm suggesting will be far less work than setting up another
system.
Let me know.

As I mentioned in my OP the NetBSD 5.x iso's installation works fine - no
problems with cd-rom boot. The first boot of the installed NetBSD 5.x Segv's
as per the original file attachment in my OP.
I installed the SIMH 3.9 vax.exe and ka655x.bin in a seperate directory
and ran the installed NetBSD 5.1. It booted w/o the Segv (and did not give
me the WinPCAP error since I used the sans-network version of SIMH 3.9).
While it doesn't help me to run it without a network I hope this helps you
find the problem. Again, installation from CD works fine - first boot
Segv's.
Thanks for your assistance.
