Its a heavily hacked V6 kernel and many of what would become the v7 utilities including the a new compiler and the standard I/O library. Same was true of PWB 1.0 - which was based on most of the code. Dennis would not formally get V7 (which had an updated kernel) released until mid '79 (FWIW: The date on a number of the files in the V7 distribution tapes in Warren's archives show Aug 1, '79 - which sounds about right for when Dennis got it out). -------------- next part -------------- An HTML attachment was scrubbed...
