The OS has no way of checking for one (unlike VMS). However, you might have
trouble finding the OS without the license. You will also need to pay extra
for the source code. (There may be an uncommented source code distribution
which you can use to reassemble the OS but doesn't count as the licensed

I'm sure some of the PDP-11 experts know a lot more about this than I do.
