 Hi,

 I have a micro PDP11/73 equipped with an RD53, RX50 and a Cipher mag tape
 drive (untested). The machine currently boots into TSX (although I don't
 have usernames/passwords so no shell access).

 I'd like to get BSD2.11 onto the machine. What is going to be the best
 route? I assume that my chances of breaking through TSX security (so I can
 use kermit) are small, so is vtserver going to be the easiest method? 
I haven't done it in many years, but after you get the machine to
boot into RT11 you can disable the TSX security stuff.  Probably a file
named "STARTF.COM" is the initial RT11 startup and it contains the
command to chain to TSX.

I suppose the easiest break-in tool would be a floppy disk with a bootable
RT11 on it.
