  Congrats!  I'm typing this on my phone so I'll be brief.  The standard
CSR address for a TU58 is 176500.  What second SLU do you have?

  Also, about  the "run"  light... Keep in mind that ODT, the prompt you're
interacting with, is actually written in microcode...not PDP-11 machine
language.  When you're at the ODT prompt, the "PDP-11" part isn't actually
in the run state,so it shouldn't be on until you actually begin execution
of some code you've loaded into memory.
