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.
