2 unusual facts about Version 6 Unix


Version 6 Unix

Since source code was available and the license was not explicit enough to forbid it, V6 was taken up as a teaching tool, notably by the University of California, Berkeley, Johns Hopkins University and the University of New South Wales (UNSW).

UNSW professor John Lions' famous Commentary on UNIX 6th Edition was an edited selection of the main parts of the kernel as implemented for a Digital PDP-11/40, and was the main source of kernel documentation for many early Unix developers.


Whitesmiths

The Whitesmiths compiler, first written for the PDP-11, was released in 1978 and compiled a version of C similar to that accepted by Version 6 Unix (Dennis Ritchie's original C compiler).
