Popis:	This work discusses the protection of the Processor Status Word of the PDP-11/60 computer and shows how a non-privileged user can modify the processor priority and execute his programs at PR7 priority level, that is, with all interrupts blocked. It also suggests some possible solutions to this problem. Finally, it considers how the problem is solved in the VAX-11.
