Re: Sadly... this is the beginning of the end
There was a lot of code-swapping between Berkeley and AT&T until AT&T's lawyers noticed that UNIX might be a money maker.
The IBM/Interactive Systems Corporation kludge included IX/370 and PC/IX (which were odd-ball variations on the theme, to say the least) and AIX Version 1 (which was BSD and SysVR1 & 2 based and ran only on the RT PC) ... All later versions of AIX were pure IBM. And showed it.
There was no System IV ... there was no System I or System II, either.
