According to Ritchie and Kernighan writing in the 'Bell System
Technical Journal':

"""C was originally written for the PDP-11 under Unix, but the
language is not tied to any particular hardware or operating system. C
compilers run on a wide variety of machines, including the Honeywell
6000, the IBM System/370, and the Interdata 8/32."""

Note that Unix at the time was written in assembler and was recoded to
C for edition 6.

Also note that the very first machine to run what became Unix was a
PDP-9, not a -7.  Not that there is much difference.
