Naoki, I am trying to build these systems following your instructions.
I am using SimH 3.8.1 on a 64-bit Ubuntu system. I am seeing these problems:

$ vax780 dboot.init 
VAX780 simulator V3.8-1
HALT instruction, PC: 00030040 (HALT)
file : unix
HALT instruction, PC: 8000043B (HALT)

$ vax780 dboot.init 
VAX780 simulator V3.8-1
: hp(0,0)vmunix
61856+61008+70120 start 0x4B4
Trap from kernel mode
HALT instruction, PC: 800004B4 (HALT)

$ vax780 tboot.init
VAX780 simulator V3.8-1
HALT instruction, PC: 00050033 (HALT)
: hp(0,0)vmunix
87844+15464+130300 start 0x530
Process PTE in P0 or P1 space, PC: 80007E43 (XORW3 @-7035(AP), at D0FD2A4A, at -70B0(R1))

Do you have any idea why the three kernels are crashing? I have not modified
your .ini files.

Also, can you tell me how you constructed the three boot tapes? What
files from TUHS and elsewhere did you use?

Many thanks for your help, Warren
