I consider v8 v9 v10 to be worth of attention, even > influential, I can think of at least 4 things, some big, some small, where post-V7 Research Unix was influential: - Streams (as STREAMS in S5R3 & greater) - The filesystem switch (in S5R3, replaced by Sun vnodes in S5R4) - /proc ! This lives on in most Unixes and in Linux - /dev/{stdin,stdout,stderr}, /dev/fd/N - Minor but a nice generalization The influence was less from code and more from published papers, but there certainly was a notable influence. I was lucky enough in the late 80s and 90s to have an inside friend in the labs (BWK), who was kind enough to obtain for me a real printed Eighth Edition manual. Later he put me in touch with Doug who at first wasn't sure, but found out that the could, sell me a Ninth Edition manual. ($50 IIRC). I bought the published Tenth Edition manuals as well. It was great to read those things, even if at the time I couldn't get to the code. For whatever it's worth, Arnold
