I recall a couple of editors and some tools were kicking around written in
B.  I would check the GCOS archives, as I believe that for a long time, B
was a popular systems programming language for that OS target.  B might
have been moved to Multics, but I have no memory of seeing it.   IIRC, most
system programming there was on in its powerful PL/1 dialect or a
Fortran/often with a preprocessor like MORTRAN or RatFor, which I did see.

Interestingly, I also have no memory of a B implementation for the PDP-10,
which like GE/Honeywell systems, was 36-bit, word addressed. I used BLISS
and SAIL on those, if not the assembler.

FWIW: Besides C, B also begat two other languages Eh and Zed, both at
Waterloo,  Eh I believe, was what the original Thoth system was written,
although it might have had some utilities in B; you have to ask someone
like Mike Malcom.  Since many/most of the 1970s mini's and later micro's,
ISAs were byte addressed, the word nature of B (and the fact that the
source to Ritchie C compiler came with UNIX), is probably what caused it to
have a more limited life.
