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: >> ... >> The PDP-11 on which UNIX is implemented is a 16-bit 12K computer, >> and UNIX occupies 8K words.

How much more powerful early Unix was compared to CP/M and MS-DOS, in a small fraction of their memory space! ------------------------------------------------------------------------------- - Nelson H.
