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).
Thanks!

I recall having an IBM PC port of UNIX in the 1980s on floppy with
a black 6x9 box and Charlie Chaplin with the red rose. I thought
it was called AIX. I installed it, and recall it being very
different from UNIX for sysadmin (different logs, different admin
commands) but similar for users. I thought it was based on System
III or thereabouts.
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.
