Copyright for the Debian os8 package

The software license is available from:
http://www.pdp8.net/os/os8/os8_license.txt

I am not a lawyer, but I interpret it as being DFSG free EXCEPT
THAT IT IS ONLY FOR NON-COMMERCIAL PURPOSES.
The export control does not apply as there is no crypto included.
Again, I am not a lawyer, and here is the full text of the license
from the site named above:
