I have been able to sysgen an RT-11 XM monitor with the idle loop light pattern enabled, and install and boot it on my PDP-11/45. Here’s a video of the idle lights:
https://www.youtube.com/watch?v=ycADKwgnLpE I built the latest simh and tu58em from source on my MacBook, then was able to do the sysgen under simh, copy the resulting binaries onto a TU58 image using simh’s TDC device, then use tu58em to copy the binaries over onto my working RT-11 4.00 distribution RK05 pack. It was pretty fun to get all this working — I had never seen RT-11's console light pattern before! —FritzM.
