I thought you'd find the slides from a talk given at SCOforum 2004 of interest, because they show that SCO also distributed, under the GPL, binutils in UnixWare and OpenServer. The talk was titled, "Open Source Components in SCO OpenServer and SCO UnixWare", and the credits list Ron Record at SCO engineering.

SCO's new position is that UnixWare is just another interchangeable name for UNIX and that SCOsource was about UnixWare, not Unix System V, but here's some more evidence that they are not the same thing and that SCOsource was primarily about UNIX System V. In this article, I'll restrict myself to things SCOfolk used to say about what SCOsource was about. As you will see, before the Honorable Dale Kimball ruled in August that the UNIX copyrights didn't pass from Novell to SCO, SCO said SCOsource was about UNIX System V source code. Now that it's time to pay Novell for those System V licenses, SCO says they were really UnixWare licenses.
