We were asked for a copy of our Unix License when we ordered the tape from
PH.  At that time the tape cost $65.  It contains the full Xinu source,
as seen in the above referenced book, but it also contains source for an
lsi11 assembler and a C compiler.  The compiler looks a good bit like the V7
PDP11 C compiler (i.e. not like the portable C compiler), so I would think
that a license would be required.  I believe we only had to show that we had
a V7 license.

PH might now have a Xinu-only tape without the development tools for which they
do not require a license, but, in the past, they did have the tape we ordered
from them, and they did require proof of a Unix license.
