Another option would be to use TU58em (a real serial port makes life
easier), and boot RT11 on the 11/05 with an image created under SimH.  I
did that recently with an S100 PDP-11 board from s100computers.com and
got RT11 and diagnostics to run.  (Long story, that.)

Then you could use that to set up an RT11 floppy on the 11/05.

RX01's are, IIRC, just standard IBM 3740 format, yes?
