They are looking into it but can't decide how to do it. Note also that 3.0 and 4.0 will not run on a VAX 11/750, they only work on a 780. 5.0 will work on the 750, I think. Anyone considering the change should carefully examine the blurb that Western puts out advertising System III (I have no idea why they decided to call it System III, since internally it's UNIX 3.0). There is a list of new features since V7/PWB. This list contains a whopping seven items - depressingly short. Three of these seven new features are new device drivers (KMC, synchronous terminals, and a parallel communications link driver). They also tout their new tty driver (better than V7, for the most part, but also totally incompatible, requiring lots of ifdefs). The other features they mention are named pipes (should take any good UNIX hacker half a day to put this into V7 without peeking at 3.0), a new accounting package, and generally newer versions of everything. Now compare this to what Berkeley has done since V7. There really are some good things in 3.0 that haven't been released before. Aside from the device drivers, they are mostly in user programs that can plug into V7 or nBSD very cleanly, such as SCCS and a much newer and better uucp, nroff, and make. Also, consider that what appears to be the same system runs on both the 11 and the VAX - something that can't be sneezed at. Finally, the licensing was done really attractively. There can be no doubt that everyone should get a System III license, since that lets you run whatever you want from PWB, V7, Berkeley, etc. I hear that an educational license is about to spring into existence, too.
