It must have been PC/IX, that rings a bell. I also had Xenix in the same time frame, it was different (and I preferred Xenix).

I can't find any evidence of this. It appears AIX 1.0 wasn't for the original PC.

Does anyone else recall this distribution and what it was called or based on?


The first 8086 port was inside of Bell Labs, but was for a system with a custom MMU. The first commercial one was Venix released in 1983 based on Version 7 with some Berkeley improvements using the MIT compilers of the time, but it had a blue label with a boring stylized V on it. IBM released PC/IX a year later (1984) and marketed heavily. It was a companion to its other unix offerings, and wasn't AIX. That port was based on System III. If anything had the clever Charlie Chaplin marketing materials, it was sure to be PC/IX. Microsoft's Xenix was also in this time frame, but wasn't marketed by IBM (and its earliest version in 1982 predate Venix, but were only for Intel's System 86 machines, and may have required an Intel MMU board (the quick research I did was unclear on this point, other than it was supported). SCO/Microsoft released in late 1983 and early 1984 versions for the commercially available PC and other variants at the time before the IBM-PC became the standardized x86 platform.

So my money is on PC/IX.

Not sure if this is true in its entirety or not.
But that's what I recall, thst it was not a from scratch rewrite but more along the lines of other vendor UNIX clones of the time. 
License the source, change the name and then beat it to death.

in terms of rewrites from manuals, while it was not the first, as I
understand it, AIX was an example of "read the manual, write the
code."

Unlike Coherent, it had lots of cases of things not done quite right.
One standout in my mind was mkdir -p, which would return an error if
the full path existed. oops.

But it was pointed out to me that Condor had all kinds of code to
handle AIX being different from just about everything else.
