“A very good place to start” – Oscar Hammerstein II
IBM 801 Building ca. 1975
Late last year I became aware of “The Unix Heritage Society”, a fascinating archive and mailing list on UNIX history (and often, tangential topics). Even Ken Thompson occasionally contributes.
There have been various TUHS discussions of AIX in the 1980s, the RT/PC, etc. Often I want to say, “no, that’s not how it was, or, at least, not how it seemed to me when I was in the middle of things”, but I’ve avoided joining those discussions.
Since I don’t know of a good history of AIX, nor the associated hardware projects prior to the RS/6000, this is my attempt to say what I can to clarify and fill in the lesser known history. (Peter Salus’ A Quarter Century of Unix is a comprehensive reference, but barely mentions AIX. The RT book is a snapshot at the time of the first release and only incidentally covers history. AIX Turns 20 reflects on the first two decades.1)
