Re: [TUHS] First Unix-like OSes not derived from AT&T code?

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?

I had a days experience with it on a POS cash register fixing a client issue. The shocker - they changed all the error messages to error codes with a look at the manual requirement. 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.
