I wrote a Fortran program to read and write RT-11 5-1/4" floppies on
a UNITY system (UNIX computer with an LSI-11 bus) over 5 years ago.
It also had list and delete commands.  Basically it emulated the PIP
utility on a PDP-11.  If I can find it, I will mail it to anyone interested
(as far as I can remember it's not too long).  I hope I had the good sense
to keep a listing at least!  I'll find out over the next few days.
