Rt-11 didn't have directories, as far as I can remember, though as far 
as I got with that was V3.

which were a leftover from RSX and compatibility mode.  The one relic of 
that which is still in VMS is [000000] for top level directory.

ISTR logging onto RSX and RSTS systems with UICs rather than usernames.
