I just discovered that this issue of the Australian UNIX User Group Newsletter contains summaries of all the talks and sessions from the Usenix Texas UNIX Users Conference - Summer 1981. https://vtda.org/pubs/AUUGN/AUUGN-V03.4.pdf In what I believe was my first public speaking role I presented "UNIX vs Godzilla -- UNIX in an IBM Environment" Lots of other familiar names in those notes too.
