Hello!
This is a long shot, but here goes, what, ah, platform was the
original DSK file created on? That is what is their copy of SIMH for
the Vax running on?

Next why not provide for us a copy of the methods used to initialize
the emulator. From that we may be able to advise you further.

And this is extremely important, did you build your own copy of SIMH
for this release of SUSE? Or was it built originally on a different
platform?

Oh and does the program run anything else properly? Other releases of
what the DSK blob you're trying to boot here, contains. It could be
our old friend VMS, or BSD or something we've not heard of before on
that DSK and so forth.
