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?

Thanks,
