Mini-Unix is for PDP-11s without memory management: one process in memory at a time, no pipes/prof/ptrace. The LSI-11 specific system, which preceded Mini-Unix and was even less capable, is LSX. See and search on the page for "Heinz" for details. -- John Cowan http://www.ccil.org/~cowan cowan at ccil.org People go through the bother of Christmas because Christmas helps them to understand why they go through the bother of living out their lives the rest of the year. For one brief instant, we see human society as it should and could be, a world in which business has become the exchanging of presents and in which nothing is important except the happiness and well-being of the ultimate consumer. --Northrop Frye (1948)
