Nice filebrowser interface. Can somebody explain to me the AIX history? I was but a wee lad at the time...
Well, I guess we can cover both AIX (with regards to Apple using it) and A/UX.
Apple started A/UX back around the same time as System 4. The idea was to use an underlying UNIX (System V) operating system with a Mac GUI on top on Mac hardware (specifically the Macintosh II series systems that were out at that time).
A/UX 2.x was released around the time of System 6 and used it as it's Mac application environment.
While A/UX 1.x was available in the form of floppies (55 of them as I recall), both A/UX 1.x and 2.x were generally sold as pre-installed 80 MB hard drives that you would swap out with your original drive.
A/UX 3.x (the one I'm most familiar with) is mainly based on System V Release 2.2 (Release 4 was the most current at the time) because it was lease expensive for Apple to license. But Apple did make modifications by adding parts from Release 3 and Release 4 (which effectively updated the functionality to being the same as System V Release 4), and they also used parts from 4.3BSD for the networking and file system.
This one was also sold as a hard drive, but was generally sold as a floppy/CD combination.
The thing about A/UX is that it is designed to only run on Motorola's 680x0 series processors.
So when Apple made the move over to IBM's PowerPC processors, they were faced with either having to port A/UX or come up with something completely new.
They chose neither.
IBM already had a UNIX operating system that was designed to run on POWER and PowerPC processors called AIX. Apple bought logic boards from IBM with PowerPC 604 or 604e processors on them that would work with AIX (4.x) and sold them as Apple Workgroup Servers.
Apple did experiment for a while with other options, but once AppleShare IP had reached a level of ability that Apple (and their clients) could deal with, they dropped AIX altogether.
