you can get alignment of the above messages with the commands that
cause/inspire them if you invoke simh in verify mode:

       vax -v vax.ini

Just as you explicitly disable rl and ts you can disable these if you
care to.

Since you seem to want to use more than 64MB of RAM, you should be
loading the ka655x.bin rom image.  Using that image will probably fix
the:

?80 2 17 FF 00 0000

P1=00000100  P2=00000000  P3=FFFFFFFF  P4=00000088  P5=00000000
P6=00000000  P7=00000000  P8=03FC0000  P9=303FFE00 P10=00001FFF
r0=00000000  r1=20088000  r2=00000000  r3=30400000  r4=03FF4000
r5=00000000  r6=04000000  r7=30000000  r8=80000000 ERF=80000000

problem you are sometimes seeing.
