Current versions of IRIX are SVR4.  You need to mention System V here
as well.

I've never heard of Interactive BSD.  I have used Interactive UNIX.
The version I used was a much more conformant version of System V.3.2
than SCO had.  I think this belongs in the first group.

I also don't like the term "fake UNIX".  "Unlicensed UNIX" or
"trademark-refused UNIX" would be better.  The point is that the
versions are derived from a single source.
