Well, that's one of 'em.  Actually there were at least two
Radix-50 character sets promugated by DEC.  I don't have
the tables here in front of me, but the tables for the pdp-11
and DECsystem-10 versions of Radix-50 were distinctly different
(and, of course, incompatible).

Just as a side note: namei() hasn't changed its name or its
information passing mechanism since 1969.  Yup, that's right:
u.u_base, u.u_count, etc. date from pdp-7 days.  Except then
they didn't have the extra "u_" in their names.  Of course,
back then there weren't pathnames as we know them now.
