SGI and IRIX German technology website reports that SGI will completely abandon its MIPS processor architecture, including its operating system Irix, in favour of Linux-powered Itanium workstations. SGI used MIPS and Irix in its products for almost 20 years, and with this switch to Intel, yet another major (historically speaking, that is) company abandons its architecture for the more common Intel one.

Solaris isn't a BSD derivative... that's SunOS (4 and earlier). Solaris is based on AT&T SVR4, which SCO now own. Having to rewrite Solaris to remove SVR4 code is why open-sourcing Solaris took so long.

Do you know this as a fact? The story I collected is different.
"We paid a big, big bag of money a decade ago to get IP rights to do what we wanted to do with Solaris", said Scott McNealy. [,+HP+SCO+probably+wont+touch+us/2100-1016_3-... ]

"We have seen what Sun plans to do with OpenSolaris and we have no problem with it," McBride said. "What they're doing protects our Unix intellectual property rights." [,1759,1785664,00.asp ]

Based on those quotes, it's unreasonable to think Sun had to remove SVR4 code, which SCO owns according to you.

1. SCO own SVR4. That's a well-known fact, and is the basis of their IBM/Linux and Novell lawsuits. That Solaris is based on SVR4 is also a well-known fact - many in the UNIX industry were rather pissed off at Sun and AT&T at the time and formed a (now-moribund) organisation to produce a rival UNIX, OSF/1. When other companies then aligned themselves with AT&T and Sun, this once again divided the UNIX market into two camps. These facts can be verified at Wikipedia, among other places.

2. SVR4 is based on SVR3 (AT&T UNIX) with features from BSD.

3. It might be true that Sun paid money to whomever was the UNIX owner at the time to do whatever they wanted with Solaris. If so, that begs the question why they had to release it piecemeal to make sure they weren't contravening licence agreements.

4. It's well known that SCO's beef is with the GPL and the fact that Linux on x86 has wiped out its UNIX profits. (The old SCO used to be the big UNIX vendor in terms of numbers, because its UNIX ran on x86.) It's also well-known that SCO for a long time, and possibly even now, distributes code under the "unconstitutional" GPL licence.

it is much more involved than that...

Solaris 1 is based on SunOS 4.1

SunOS 4.0 has influences from 4.3BSD (Tahoe)
SunOS 3.2 has influences from UNIX System VR3

therefore Solaris 1 has roots on 4.3BSD and is not based on UNIX System VR4, however as you can see Solaris 2.0 got influenced by UNIX System VR4.

it is not a trivial story...

SCO and Novell are currently disputing who owns Unix. SCO doesn't own much of anything it looks like, based on the wording of the contracts.
