Thanks, Doug and Warren, for the new files at http://www.tuhs.org/Archive/PDP-11/Distributions/research/McIlroy_v0/ At the TUHS mirror at my site, you can find an additional file http://www.math.utah.edu/pub/mirrors/minnie.tuhs.org/PDP-11/Distributions/r… ftp://ftp.math.utah.edu/pub/mirrors/minnie.tuhs.org/PDP-11/Distributions/re… that is less than half the size, and is (somewhat) searchable, thanks to Adobe Acrobat Pro 11 OCR conversion. Please include that in the TUHS master archive, even renaming it to the original file, if you wish. I like the beginning of "Section 2. Hardware", where Dennis wrote: How much more powerful early Unix was compared to CP/M and MS-DOS, in a small fraction of their memory space! ------------------------------------------------------------------------------- - Nelson H.
