We had the same problem the first time we booted 4.3 on
a VAX 750 with a RA81 disk: the system prints the usual
autoconfig messages, asks for the root device, then panics "iinit".

This is because we used the boot and copy programs on the 4.2
cassette.  You can't do that with an RA81 disk, because the partition
sizes are different under 4.3.  In particular, the swap partition
starts in a different place.  The effect is that /vmunix is read into
memory intact, but can't make sense of the miniroot file system.

To get around this, extract the /boot and /copy programs from the
4.3 miniroot to /43boot and /43copy, then:

	# halt
	>>>B/3
	Boot
	: ra(0,0)43copy
  ...
	From: ts(0,1)	(or whatever your tape device is)
	To: ra(0,1)
  ...
	>>>B/3
	Boot
	: ra(0,0)43boot
  ...
	Boot
	: ra(0,1)vmunix

That should do it.
