Whilst I agree the claim is startling, there is a connection between
early C and the GE 635.  The little known Snyder C compiler has back
ends for the PDP-10, PDP-11, and Honeywell 6000 series (nee GE 635).

I believe this compiler was started when Snyder visited Bell Labs in
1973, and it comes with a very archaic version of Yacc.
