Yup. Amusingly, at one point, very early on, at MIT we were using octal for
addresses, in the very similar form 'a,b,c,d'. (I'll bet I could find an
example of that in the archives of the MIT-CSR UNIX machine, whose
file-system has been preserved.) I don't think we would have done octal just
to be different; it was almost certainly before decimal 'a.b.c.d' was the
effective standard.
