> From my understanding it was without fee or royalty?

While I don't have a copy of the license before me, I gave many, many talks 
about our system at Tektronix. The more-or-less wording of the license 
granted to the four companies was: In exchange for reviewing the draft of 
the book and implementing the virtual machine, licensee is hereby granted 
an irrevocable world-wide, non-exclusive, royalty-free license to 
distribute the Smalltalk-80 system by incorporating into a product of the 
licensee.
