Not all CDC machines did; consider the Cyber 200 series:


But that only made sense, as the Cyber 200 machines are bit-addressable.
  For a time, my work straddled both the Cyber 70 and 200 systems, and
so had to adjust my thinking.  Not just bit-ordering, but the 70/6000
used 6-bit display code, while the 200 used 8 bit ASCII.

Fun times.
