Lots more of the backstory and history is here, for anyone curious:

and especially:

The reconstruction of the IMP as a running system was triggered by a 
patent lawsuit, where the IMP was highly relevant as a proof of 1970s 
"prior art", and getting it running again to be a demonstration at trial 
was the motivator.

Enjoy,
