If you look in the tarballs for conformations of each molecule you'll find
PDBs:
http://ambermd.org/tutorials/advanced/tutorial32/GlycerolConfs.tar.gz
http://ambermd.org/tutorials/advanced/tutorial32/MPDConfs.tar.gz
There are PDB files for many conformations, complete with annotations
showing what Amber NMR restraints would be necessary were you to run sander
to arrive at that same local minimum. There are also "initial guess"
topologies and prepi files--starting points for your force field
development based on gas phase charges that might be created by hand, that
will serve as guides for tleap and other amber programs. One thing I don't
seem to have in there is an Amber inpcrd format file for each molecule, but
you can generate that yourself from one of the PDBs and the prepin files
with tleap, or by taking the given topologies and using cpptraj to convert
one frame of the trajectories in this tarball to Amber restart format:

I didn't expect you to run all the ORCA calculations yourself, so I opted
to just show you how the mdgx &configs and &speval modules work. The
results needed for the next step are provided so that you can get straight
to the data fitting part.
I'm still due to make some updates to the website based on MPS results with
pmemd, and there's a big new patch to mdgx coming soon, just didn't make it
in time for AmberTools19. I'll see about improving this tutorial with that
update.
