[Simh] Migration utilities.

[pgaray at bigfoot.com]

I think that for PDP-11 simulation you could only copy the
image from a system that had the same controller that is
emulated by simh. AFAIK the boot block there is device
specific. On vax the console takes care of initial device
handling so the drive (in this case the image of the drive)
can be moved to a different hw.
