I was able to load the Nebraska sar file found at 
http://minnow.cc.gatech.edu/squeak/1356 into a 3.9 image.

In order to get  ' NebraskaServerMorph serveWorld: World onPort: 9091' 
to start up and not give the DNU you mention
modify  NebraskaServer (class)>>newForWorld
from: ^super new initializeForWorld: aWorld
to: ^super basicNew initializeForWorld: aWorld

I'm not putting this is as a change because even though this gets 
something running I have never used Nebraska do I have no idea if this 
is the only change you'll need to make.
