Of the PDP-11 OSs RT-11 has the fewest requirements to
run.
I thought XXDP+ required even less (it doesn't use interrupts if it can
avoid them, for example). The argument being that an OS designed to load
diagnostics should run even on partially defective hardware.
Now whether you class XXDP+ as an OS is another matter.
