While cruising olduse.net I came across this puzzling entry in net.general Department of Computer Engineering and Science Case Western Reserve University Cleveland, Ohio We would like to announce our connection to Usenet. We are a private university located in Cleveland, vacation spot of the midwest. The department's primary facilities consist of: VAX 11/780: hardware: RM05's, TU77, DZ-11, DH-11 (able), 2.5 Mbytes. software: 4.1 BSD PDP 11/45: hardware: RM02, DS330 (RP04), RK05, RX02, RS04(solid state) cache45 (able), DH-11 software: UNIX V 6.9999999 What is UNIX V 6.9999999?? I suspect it's v6 with a bunch of patches, but not quite v7? I've seen from some Russian stuff that they prefered v6 on pdp-11's as it "ran faster" than v7 and needed far less ram/disk space... I know it's 30 years too late to ask them what it is but I figure someone may have actually ran/used 6.9999999... Thanks Jason Stevens
