Well that's certainly before ICs I think that was in the 1950s and it was
some early calculators that killed slide rules. What kind of "processor" were
they using? I'm not so sure there was real HLL before Adm. Hopper. And no
binary by Babbge. Do you have any links or anything from the '40s?

I'm not so sure about that. I have documents from as early as 1948 showing
programming in machine language, though each of these use decimal numbers for
the opcodes and addresses. While of course many machines were binary
internally, I've never seen anyone actually code programs in binary.
