I cannot install 1.6.2 on the VAX/simh emulator, by booting the iso image.
But the 1.5.2 iso works okay.

Appears to be a known issue:

I'm using simh V3.2-0 on a NetBSD 1.6.2 i386 host.
The 1.6.2 iso boot hangs at this stage:
	NetBSD 1.6.2 (INSTALL) #0: Wed Feb 11 09:24:13 UTC 2004
	    autobuild@tgm.netbsd.org:/autobuild/netbsd-1-6-PATCH002/vax/OBJ/autobuild/netbsd-1-6-PATCH002/src/sys/arch/vax/compile/INSTALL
	[...]
	boot device: ra0
	root on md0a dumps on md0b
	Clock has gained 135 days - CHECK AND RESET THE DATE.
	root file system type: ffs
	[...hang...]

The 1.5.2 boot continues to the install menu.

Here is my simh config file:
SET CPU CONHALT
SET CPU 32M
load -r /export/netboot/simhvax/lib/ka655.bin
set rl disabled
set tq disabled
set rq0 locked
set rq0 cdrom
at rq0 /export/netboot/simhvax/vaxcd.iso
set rq1 offline
set rq2 offline
set rq3 offline
boot cpu
