actually, in 48k basic interrupts stays disabled. but in 128k routine at #5B01 (which does ROM swapping) contains DI followed by EI. this is the cause of your problems with mysterious interrupt re-enabling. -

In fact what you could do is enable interrupts and HALT. Immediately after that you can get the address that it returned to. This way it will work with any ROM without having to worry about safe entry points etc. -
