  That's true but unfortunately Joe built it for an 11/05 because he wanted to duplicate the original DEC image.  That version uses 177776 to alter the PSW and in particular the CPU priority level, and that doesn't work on any of the LSI PDP-11s.  Yes, I know - use MTPS/MFPS instead, and Joe even provided a conditional assembly option for just this eventuality.  Gotta re-assemble to use it though.
