The 11/73 is the KDJ11-A, based on the DCJ11 chip, which has a
processor status word at 17777776.
It also just so happens that (at least for all the DEC pdp-11s) a
machine with memory management also has a processor status word.

Not that I know of. The TSX versions of the drivers are the RT-11
versions rebuilt to use PAR6 instead of PAR1 for access to user
buffers, et al. Same documented restrictions of PAR1 use in the
RT-11 doc set would then apply to PAR6 when using the drivers under
TSX...
